DRIVE SYSTEM DIMENSIONAL DATA
SERIES 21 standard V-belt drives in controllable (C) and spring-loaded (M) configurations may be applied in various combinations of the 3 to 8 inch sizes to obtain desired output speeds. Horsepower range is fractional thru 5 Horsepower. Convenience in the use of standard “A”, “B” or “C” belts make these lighter duty drives desirable.
Exceptionally high ratios in larger diameter drives are available due to the interlocking face designs of these pulleys.
Installation of a drive combination takes only a few minutes. The C-type pulley is mounted on the motor and the M-type pulley is mounted on the driven shaft. The control bracket is bolted in place, and the proper V-belt is snapped into position. No lubrication is ever required due to the plastic impregnated sintered bronze bushing design. The drives are maintenance free.
CONTROL MODEL 350
Model 350 control fits four controllable pulleys. The control is composed of an angle bracket which is bolted to a convenient location on the customer’s machinery, a threaded control stem and handwheel, a torque bracket which fits into the controllable pulley, and a pair of stop nuts. The stop nuts may be adjusted to limit speed range as required.
