What Are Plastic POM Timing Belt Pulleys?

Plastic POM Timing belt pulleys is made of POM mateterial.  As with many other synthetic polymers, POM is produced by different chemical firms with slightly different formulas and sold variously by such names as Delrin, Kocetal, Ultraform, Celcon, Ramtal, Duracon, Kepital, Polypenco, Tenac and Hostaform. POM pulleys are a wheel on a shaft or an axle. It is developed in order to support the change of direction and movement of a belt or a cable along the circumference.  Pulley is grooved in between two flanges all over its circumference. Toothed belts and pulleys are of major importance in synchronous drives based on flexible components.Their curvilinear tooth profile was designed with high-speed and provide excellent registration without a loss in torque carrying capability making them ideal for precise registration applications and heavy loads. Timing belt drives are increasingly replacing inefficientroller chain sprockets for the transfer of power from shaft to shaft, torque multiplication, speed reduction, speed increase, and shaft synchronization.

What are the advantages of plastic POM timing pulleys?

1. High Power Transmission Capacity: Plastic POM timing belt pulleys have advantages of high stiffness, low friction, and excellent dimensional stability. POM pulleys are able to give more power than a friction drive belt because of the Minimum radial load on the shafts and on the bearings. A non-extendable belt that transmits the motion without significant stretching and therefore without lost motion. The transmit capacity has a feature of high torques at low speed. High mechanical efficiency, as much as 98% when properly maintained. By contrast, chain drives are in the 91-98% efficiency range, while V-Belts average in the 93-98% range.
2. Good performance at high speed: Transmission of absolute asynchronous motion because of absolutely without slipping in motion. Regular and constant motion, since the toothed belt, is free from polygonal winding and the consequent speed variation typical of chain transmissions. Timing belt pulley has Wide speed range, especially important when the entire speed range is developed from a single source
3. Silent running, good performance, minimum overall dimensions
4. Clean operation is easy and no need for lubrication and rust-resistant.
5. POM timing pulleys may be machined using traditional methods such as turning, milling, drilling etc. These techniques are best employed where production economics do not merit the expense of melt processing. The material is free-cutting, but does require sharp tools with a high clearance angle. The use of soluble cutting lubricant is not necessary, but is recommended.

What  Pitches of Plastic  POM Timing Belt Pulleys Can We Supply?

 Toothed pulleys are coded on the basis of:

– the number of teeth
– pitch, expressed by one or more letters
– width, expressed in hundredths of an inch
– flange ( if any ) expressed by the letter F.

Example:
Pulley 10 XL 037 has:

– 10 teeth
– pitch identified by letters XL
– a belt width of 37 mm

N = Number of pitch lengths or teeth on a pulley
P = Pitch is the distance between the axes of two adjacent teeth irrespective of whether these teeth are on the pulley or
the belt provided that measurement is taken on the circumferenceor pitch line
t = Belt thickness
Dp = The diameter of the pulley pitch is obtained from formula Dp = (P · N)/P
De = External diameter of pulley De=Dp – NF
Df = Flange diameter
d = Bore diameter
