Today’s automated machinery makes heavy use of servo motors to increase production and decrease waste. When a speed reducer is required for the servo motor, the torque density of the servo is best matched to a planetary style reducer. Shimpo’s Able planetary reducer is produced in a modern plant using the latest generation CNC machinery. This results in extremely close tolerances and very low gear backlash, in a design shown for many years to be robust enough to handle high power servo motors. Shimpo offers two variations, VRAF (medium duty, lowest cost) and VRAL (heavy duty, common mounting and output shaft dimensions, longest life rating). Shimpo’s RXC ring cone traction drives use a gearless planetary design to provide adjustable speed reduction without loss oftorque. The typical RXC drive produces a speed range of 800-0 RPM, with full holding torque at zero speed. Unlike modern electronic drives, ring cone drives show an increase in torque at lower speeds. Coupled with an internal device that increases torque during momentary overloads, the traction drive really is the ox that will pull your plow through the worst conditions. Sometimes it still makes sense to choose an old fashioned p o w e r - house. Cycloidal speed reducers have been popular for decades, for applications that are abusive to a drive train. The typical Shimpo Circulute 3000 cycloidal reducer will routinely shake off a 500% shock load, and keep on working. The cycloidal design includes an eccentrically bored roller bearing centered in a sprocket-like wheel. The wheel engages pins along the ID of the housing and transmits torque to the output shaft. The number of wheel teeth vs. the number of housing pins determine the reduction ratio, and the high percentage of teeth in engagement with pins is what provides such high shock-load capability. This style reducer, although more expensive than a helical gear reducer, solves longevity issues and eliminates headaches.
