PHGM / Parallel Helical Geared Motor

A torque-arm anchors the Reducer and provides stability to the mounting with Equipment assembly turnbuckle. The Fenner Parallel Helical Geared Motor Shaft Mounted Speed Reducer is manufactured in eight gear case sizes, designated by the letters B through to J. The eight sizes may have anyone of twelve nominal gear ratios, 5:1, 6.3:1, 6.8:1, 10:1, 13:1, 15:1, 20:1, 25:1, 30:1, 40:1, 50:1, and 63:1. A very wide choice of final driven speed can be determined by the use of the ratios, with different motor frame size adaptors to mount, according to the application need. The units will normally be oil lubricated, but they are equally suitable for "lubricated for life" greases.

Improved Power Rating Backstop assembly in the Adaptor, to facilitate effective stoppage Separate provision for fixing the Torque arm without opening casing assembly bolts. Compact Design results in improved performance of Equipment.
