Variable Speed Pulleys

Overview

The variable speed pulley is a well established drive; designed to give continuous speed variation at a comparative low cost.

Unfortunately it is well known that this design is subject to excessive flange wear due to the type of drive systems employed.

 

However, our new variable speed pulleys eliminate this problem by introducing a completely new drive system:

  • The hub is made from induction hardened steel, hard chrome plated and ground to give uninterrupted slide fit with flanges. Keys are not used with this application.

  • Moving flanges give a wide contact area therefore eliminating uneven belt pressure.

  • The pulley flanges are coupled by means of nylon sleeve couplings to the outside of the flanges and by two flates machines on each end of the pulley hub. Two springs situated inside the nylon coupling give the desired pressure.

  • There is provision for re-greasing the pulley slideways, although the grease chambers are pre-packed before leaving the factory.

Styles we offer:

Variable Speed Pulleys “Mono”

Variable Speed Pulleys “VOL”

Variable Speed V-Belts
