Vari-speed Pulley By Vijay Enterprise

Vari Speed Pulleys

The Vari-Speed pulley has been designed for use
where frequent speed changes are required. This pulley
consists of two facing cone shaped discs - each sliding
laterally on a sleeve, forming a V-Grooved pulley of
infinitely variable pitch diameter.

The V-Belt is held in perfect alignment as the two consisting
cones of the pulley move equally on either side. An
adjustable motor base carries the motor and the Vari-Speed
Pulley and by the rotation of the hand wheel this can
be moved towards or away from the driven shaft automatically,
increasing or decreasing the effective diameter of the
Vari-Speed Pulley and causing a change in the driven
speed. Because of its special design, the change of
speed can be effected easily while the machine is in
motion.

No attempt should however be made to change the speed
unless the unit is running.
