Product Description

High Speed CNC Poly-V Pulley for Electric Motor Drive Systems


  Poly-V is a multi rib belt drive whose special construction allows it to be used with very small pulley diameters, reducing noise and vibrations. It solves many drive problems in a number of applications such as machine tools, wood working machines, fitness machines, compressors, fans etc. SIT pulleys have been designed to guarantee optimal drive performances and life. They are ideal high ratio or high torque drives. With only 1 belt, tensioning is easy and you do not have to worry about matching belts. For further information or help in selecting a drive contact P.T. Parts.

  Characteristics:

· Suitable for transmitting power up to approx. 600 kW
· Wide range of section for every drive requirement: J , L & M
· Suitable for small size pulleys diameter (20 mm), achieving very high
· peripheral speed (up to 60 m/s)
· The belt can counter flex and work on the backside
· Wide range of pulleys for taper bush available from stock

PRODUCT DETAILS

We can supply the whole series of Muti-Wedged Pulleys (J3-M20), from DP 20mm to
710mm. The pulleys are available in standard straight and taper lock bores.
Multi-Wedged Pulleys are made of GG25,GGG45,S45C or other materials requested
by the customers.

     
 

The pulleys are machined by highly precise CNC, dynamically balanced and black
coated. They have the features of high precision, steadiness and smooth
transmission. They are suitable for kinds of precise, high speed and heavy loaded
transmission equipments. They can also be used on auto motors.
We can manufacture specially designed Multi-Wedged Pulleys according to
customers' requests.

PRODUCT ADVANTAGES

Poly-V Drives are the compact alternative to the standard Vee-Pulley Drives. P.T. Parts carry all of the
Poly-V pulleys and belts in this Catalogue on the shelf and if special diameter pulleys are required they
can be made in our factory.
The ribbed belt combines the high flexibility of flat belts with the high performance of V-belts. The Vshaped parallel ribs are made from a wear-resistant rubber compound. The high strength tension cord is
designed for the many applications of ribbed belt. It is embedded in a rubber adhesive mixture and
covers the entire width of the ribbed belt. Fiber reinforced, wear resistant rubber compounds ensure
quiet operation, oil and heat resistance and a long belt life.
Other features of the Poly-V drive systems include being able to transmit up to 600kW with just one
belt. Poly-V belts can be up to 98% efficient. High speed ratios can be achieved, up to 20:1 with off the
shelf sizes and up to 60:1 with special pulleys. Due to the single belt design, uniform tension is put on
the belt across all grooves. Noise levels can also be reduced by changing over to Poly-V drives. Less
maintenance is required on Poly-V drives and you do not have the problem of one belt wearing faster
than the other because there is only one belt.
All of the pulleys that P.T. Parts carry are made in Cast Iron, the smaller pulleys have blank or pilot
bores while the larger ones are machined to suit a taper lock. Poly-V belts should be run on grooved
pulleys for the best transmission of power, however flat pulleys can be used as idlers or even drive
pulleys if required. Due to the flexibility of the Poly-V belt, flat drive pulleys can also be placed on the
back side of the belt to make quite complicated serpentine drives all driven from the one drive shaft. It
should be noted that when using a flat pulley the transmittable torque will be reduced.
