ABSTRACT:
A speed changing device wherein the driver and driven pulleys can be replaced to attain a desired increase or decrease in rotational speed. The distance between the driver and driven pulleys is adjustable so that the tension of the drive belt coupling the driver and driven pulleys is also adjustable. The mounting plate upon which the motor and driver pulley are mounted can be tightened securely against the housing so that the previously set tension can be retained during the operation of the speed changing device.
