European Standard Groove Multi Ribbed Belt Pulley

Ribbed belt pulley of different types ( according to type and width of ribbed belt). The material used is cast iron EN-GJL-250 UNI EN 1561, and for only a few types it is steel C45 E UNI EN 10083-1. They have a small prebore that can be machined  according to  customers' requirements. Moreover the most common types are available also with taperlock bore.

European standards:

a) V-belt pulley for taper bushing: SPZ, SPA, SPB, SPC, up to 10 grooves   

b) Adjustable speed V-belt pulleys and variable speed pulleys              

c) Flat belt pulley and conveyor belt pulley

Bore: pilot bore, finish bore, taper bore, bore for QD bushing

Technical parameters:

Advantage:

1. Precise guidance: The design of ribbed belt pulley can achieve precise guidance function. It can guide objects or workpieces to move along a specific track to ensure the direction and accuracy of movement.

2. Reduce friction loss: The belt pulley closely matches the seat through the groove, so that rolling friction replaces sliding friction, thereby reducing friction loss and energy consumption.

3. Lightweight structure: ribbed belt pulley is usually made of high-strength materials, with a simple and lightweight structure, making it easy to install and adjust.

Application:

1. Automobile: multi-ribbed belt pulley can be used in the transmission system of automobile engines to improve the performance and economy of the vehicle.

2. Engineering machinery: multi-ribbed belt pulley can be used in the transmission system of engineering machinery to improve the working efficiency and reliability of the machinery.

3. Ships: multi-ribbed belt pulley can be used in the transmission system of ships to improve the performance and safety of the entire system of the ship.
