Gear Drives

Author: E.E. Kimberly

Because of vibration and shaft deflection, a pinion on the unsupported end of a motor shaft, as indicated in Fig. 13-1 (a), should not be used to drive a load greater than 75 hp. In applications requiring more than 75 hp, it is advisable to use either an outboard bearing, as Fig. 13-1 (b), or two outboard bearings and a flexible coupling, as Fig. 13-1 (c).
