A Brief Introduction to the Planetary Speed Reducer

Posted on by

The planetary reducer is an industrial product which has a wide range of applications. Its property can compare beauty with other military speed reducers, but its price is equal to the price of the common industrial goods. Therefore, it is very popular in a lot of industrial fields.

In the passage some basic concepts of this speed reducer will be introduced in order to help people get a general idea quickly. What comes first is about its series. It refers to the series of the planetary wheel. Sometimes, because a set of planetary wheels can not meet the relatively big transmission ratio, there is need to increase one or two sets of the wheels in order to satisfy the requirement of the transmission ratio. With the increase of the gears, the length of this speed reducer will correspondingly be increased and the efficiency will be reduced to some degree. The next concept is about backlash. The so-called backlash means a tiny angular displacement. The unit for this backlash is “minute”, which means sixtieth of one degree. Back clearance is another name.

Since people get some ideas about this speed reducer, it is turn to talk about its functions and features. As far as we know, the main transmission structure of the planetary speed reducer includes planetary wheel, sun wheel and outer ring. Compared with other speed reducers, the planetary reducers are characterized by the following features, such as high rigidity, high accuracy, and high transmission efficiency, high ratio of twisting moment and cubage and maintenance for life. On basis of these features, most of the planetary reducers are installed on the stepper motor and actuating motor.

Their main functions are to reduce the rotating speed and increase the torquemoment. They also play an important role in matching the inertia. What’s more, it has also other unique features besides for the above-mentioned merits. Its cubage is quite small, its weight is light, its loading capacity is high, its service life is long and its operation is very stable without loud noise. Owing to its different features, it is indeed very popular in different fields, such as engineering plant, metallurgy, mine, petrochemical industry, construction machinery, light industry, automobile, ship and weapon. The temperature of this reducer ranges from -25 to 100 Celsius degrees. At the same time, the working temperature can be changed through changing the lubricating grease. All in all, this reducer is very popular in the industry.

Oil Seals

Posted on by

In terms of an oil seal, there are a lot of different types. Depending on how they are constructed, U-ring oil seals as well as block vee rings can be used as a rod seal, a piston seal or even a symmetric seal. U-rings and block vee rings are called single acting seals, also known as unidirectional seals, and have to be mounted back to back in cylinder applications that are double acting.

A Block Vee seal is really more compact and performs better under high pressure conditions than a U ring does. V ring seals are made of all rubber and are primarily used to get rid of dirt and other types of contaminants. V rings are stretched over a shaft and sealed against the side of housing or another type of machine component. Besides, more oil seals are introduced as there are several different kinds of clearance seals, also known as labyrinth seals. The one feature they all share with each other is that they all work on a principle of positive clearance. This means that there isn’t any rubbing that occurs against the shaft or the housing.

A lot of labyrinth seals are made up of a rotor, which rotates, and a stator, which is static, piece with a radial gap between the two pieces. The gap has to be bigger than the radial clearance of the bearing that is being sealed. Also, the operating speeds as well as the temperature have to be considered when utilizing a labyrinth seal. These kinds of seals typically don’t perform very well at lower operating speeds.

Another type of labyrinth seal is a laminar sealing ring, which utilizes a series of flat metal rings, similar to washers, of different diameters to make a labyrinth seal. Bearing isolators are a dynamic kind of seal that is designed to keep bearings protected from outside elements. They are also made up of a rotor, a rotating piece, and a stator, or static member. Some bearing isolators are made out of labyrinth construction but others use O rings or other kinds of positive seals.

To Eliminate Noise from a Switch Mode Supply

Posted on by

A switching mode power supply is very efficient in its working. Although, the supply is designed in such a way that it produces noise that is inaudible to the human ear, it sometimes gives a lot of noise especially when it gets old.

The good news is that if your switching mode power supplies producing a lot of noise there are ways in which you can eliminate the noise.

 

High-pitched whine with a fan

The noise is caused by lack of lubrication in the fan bearing. To eliminate the noise you should lubricate the bearing. This calls you to unplug the device from the power supply and remove the fan’s bearing protective plating. You should then put a few drops of sewing machine oil directly onto the bearing.

You should note that some protective plating is held by screws while others are held by a thick sticker.

High-pitched whine without a fan

This noise is usually caused by external electromagnetic interference (EMI). To solve it you need to move the power supply away from anything that produces a large amount of EMI. Some of the objects that tend to produce a lot of EMI include: large speakers, large batteries, fluorescent lights and flat-screen monitors.

If you remove the supply from these objects and the noise persists, it must have been caused by a dry capacitor. You should remove the capacitors together with the soldering iron and then replace them with new capacitors.

You should note that capacitors have the ability of causing massive electronic shock; therefore, after unplugging the power supply you should leave it unplugged for at least three hours before you remove the capacitors.

Low-pitched hum

If the low-pitched hum is annoying, you should put the supply in a metal casing in order to shut the noise in the casing. All you should do is to visit your local store and find a casing that will fit your entire power supply unit. You should then place the supply inside the casing and screw the casing shut.

Conclusion

These are some of the ways in which you can eliminate the noise in a switching mode power supply unit. If you do all of the above and the noise persists, you should take your device to a professional who will rectify the problem for you.

To ensure that your device lasts for a long time without developing problems, it’s good that you buy your device from a reputable seller.

Pallet Truck: For Large Weights

Posted on by

Pallet Jack scales also known as a pallet truck is an ideal tool which is typically used to weigh a variety of large items including pallets, drums, kegs and barrels. In a pallet jack scale, the forks are separated from the front wheels as the hydraulic jack is raised forcing the load upward until it clears the floor. The pallet is lifted as much as necessary to clear the floor for subsequent travel. In just one operation, one can lift the load, read its weight, and move it to its destination using the Pallet Jack scales.

This scale is ruggedly built to be cognizant of the extensive industrial use. It delivers reliable weighing results or counting results wherever it is used. These scales are used to speed up the warehouse and shipping processes. Heavy duty Pallet Jack scales can be used for permanent or portable installations. The adjustable leveling feet and the optional four-way ramp access make the loading process simple.

A typical scale consists of one set of pallet, an indicator box (with indicator), a junction box and a built-in printer which is optional. There are different types of Pallet Trucks in the market. An ideal scale should have a leak proof design, extra roller for easy moving, plastic bonded three lever positions, easy to operate, silent in operation, minimum pulling power, no oil leakage, minimum maintenance and maximum mobility. There should be a constant floor contact and stability. The wheels should sustain heavy loads and hence minimize wear and tear. The Pallet Jack scale should provide for easy operation from all angles ergonomically.

A scale should be designed to reduce the pulling power and minimize operation fatigue. Some of the key specifications of a Pallet Scale are the load capacity, lowest fork height, highest fork height, turning wheels, load wheel single, load wheel double, fork size, fork overall width and fork length. Self-Propelled Electric Pallet Truck and Pallet Jack with scale, 4500 lbs, are some of the latest Pallet scales available in the market. Ergonomic handle features, easy to operate throttle with infinite forward and reverse speeds, lift / lower controls, horn and safety-reverse button are some of the features of these models.

The drive motor controller prevents unsafe starts after the safety-reverse button has been inadvertently struck. Double reinforced welded forks with adjustable tie-rods increases the years of service. Electromagnetic disc brake with automatic dead-man feature activates when the user releases the handle. An integral battery charger and a battery level gauge are included in these models.

The pallet scale rolls smoothly on the polyurethane, steer and load wheels making them one of the most reliable tools. A pallet scale maximizes efficiency by eliminating wasted time and floor space when checking inbound and outbound shipping weights of up to 5000 lbs. One can conclude that quick verification of incoming / outgoing freight, checking weights anywhere in the plant, in transit without hauling loads to a platform, all-purpose mobile scale, batch and drum filling and inventory control are a few of the many uses that a Pallet scale can offer.

Pallet Jack Scale
Scales are used for taking various measurements, whether it is weight, volume or mass. Now-a-days digital scales are used largely. Scales give the measurement which is required while disposing anything or to accommodate anything.

Rotary Die Cutting

Posted on by

Rotary die cutting is a process used to cut paper, metal, rubber, plastic, vinyl and other material in a predetermined shape and size. This method is used to cut shapes and designs that cannot be accomplished by a straight cut on a web press or a guillotine cutter.

The rotary cutter uses knife-edge cutting blades designed to cut a particular shape. A machine presses the die into the material to produce the desired shape. The blades can be designed to cut a diverse range of raw materials. Labels, envelops, folders, cartons and documents are just a few items produced using the rotary die cutting process.

The cutting dies used in the rotary die cutting process are made from tungsten carbide. It is a very hard and expensive substance used in high volume production processes that justifies the extra costs incurred. Perforated blades or dies are used to form perforations on paper. These can be used for making receipts books, bills and tickets. Rotary die cutting equipment for industries involves relatively low upfront costs ranging from $50,000 to $70,000. However, the cost of replacing old and worn out blades is high.

One major drawback of rotary die cutters is that changeovers are time consuming and difficult. This is because they require excessive amounts of material to re-register the printing to the desired cutting and creasing specifications. Rotary die cutting equipment only registers in the direction of travel. If the material shifts in any other direction, defects begin to appear.

The rotary die cutter process is economical over a longer period. It is extensively used in manufacturing industry and stand-alone die cutting firms. However, the technology is changing at a fast pace, and new processes like laser die cutters are already in use. These are much faster and accurate than rotary die cutters.

All about Pantyhose

Posted on by

Pantyhose (also known as tights) are sheer close fitting coverings of the body from the waist to the feet, most frequently worn by women. Like stockings they are usually made of nylon. The one-piece pantyhose garment appeared in the 1960s and provided a convenient alternative to stockings (nylons).

The term ‘pantyhose’ originated in the United States, referring to the combination of ‘panties’ (an American term for women’s underpants) with sheer nylon hosiery. In the United Kingdom, they are called tights, a term that refers to all such garments regardless of denier. In the U.S., the term tights is used for non-sheer garments similar to pantyhose, such as those worn by girls, dancers and athletes.

Pantyhose are worn for a number of reasons. Sheer pantyhose that match the skin color of the legs can enhance the appearance of legs, making them look smoother. Darker pantyhose can enhance the legs by outlining the shape and by making the legs seem slimmer. Brown colored pantyhose give the illusion of tanned legs; an ‘instant tan’. Pantyhose also has a practical use, as it can provide warmth in colder weather and let one appear “bare-legged” even in the winter. Pantyhose that are knitted with lycra enhance blood circulation by applying even pressure on the legs throughout the day.

Pantyhose are currently a standard sight in offices worldwide, where they have been accepted as part of a professional dress code for women. Though a barelegged trend is now popular amongst younger women, hosiery is still common in offices and places where formal dress is required. Schools with uniforms often require some sort of hosiery as a part of the uniform (usually pantyhose or tights).

Most pantyhose are composed of nylon and a small amount of spandex, which provides the elasticity and form fitting that is characteristic of modern pantyhose. Unfortunately, the nylon fabric is somewhat prone to tearing and it is common for very sheer hose to ‘run’ soon after snagging on something rough or sharp.

Pantyhose worn for fashion have a standard construction. The top of the waist is a strong elastic. The part covering the hips (panty area) is composed of a thicker material than the legs. The gusset or crotch is also a stronger material, sometimes made of cotton. The legs of the pantyhose are made of the thinnest material which has a consistent construction down to the toes, which may be reinforced to guard against wear. However, a constant complaint of pantyhose is that they “run” or tear frequently, which ensures that wearers must constantly purchase new pairs.

Pantyhose are available in a wide range of styles. The sheerness of the garment, expressed as a numerical ‘denier’/’dtex’, ranges from 3 (extremely rare, very thin, barely visible) to 20 (standard sheer) up to 30 (semi opaque).

Pantyhose are sold in a variety of colors and textures (patterns). In business wear, the texture is usually neutral and the most common shades are beige, gray, white, and blacks, while fashion styles popular among younger women include a wide range of colors and textures.

Pantyhose are considered a part of the lingerie wardrobe, and thus a turn-on for many men when they see them on the wearer. Styles which are shiny, silky, and sheer-to-waist are attractive to many men their alluring qualities even triggering pseudo-transvestic feelings about this most feminine item of women’s clothing.

All about Piston Pumps and Their Beneficial Operations

Posted on by

Piston pumps are there almost everywhere in our lives. But, it’s just that we are not aware of their existence or their usefulness. The axial one are used almost everywhere but they are most useful in the aerospace industry.

Well, before talking about this and its use in the various industry sectors, let us know a few basic things about them. These are nothing but positive displacement pumps that have a number of cylinders arranged in a circular pattern within a cylinder block. This block known as a rotor or a barrel, this is a key component in their assembly. The size and surface texture of this cylinder bores is critical to proper performance and life of the assembly.

This comes in many varieties that include axial radial inline form, radial-piston form, and also in plunger. They also differ based on the type of component they are used like bronze, brass, steel, stainless steel, iron, nickel alloy, or other material.

These pumps are used in lower pressure applications, unlike plunger pumps which are high pressure pumps. Indeed, this provides an excellent solution for many hydraulic oil pumping applications. However, the pumps used in these operations have iron cylinder and piston with a steel piston rod.

Whatever model of piston pumps or pressure washer pumps you intend to buy, always go for manufacturers whose products are acknowledged for high functionality, low power consumption and excellent durability. They should also come with rounded construction that has no drum-type surfaces to amplify noise.

Also, as in a centrifugal pump where restriction or increased head creates reduced flow, a piston pump has a very flat flow performance curve. This may result in blockages, which is very hazardous. Hence, use only piston pumps that have safety devices such as unloaded valves.

A.R. North America provides many industrial products with best quality like piston pumps, plunger pumps, car wash pumps.
