MOUNTING FACE SYSTEM

摘要

A motorized drum has a drum shell having an inner periphery and a central axis, with a motor and a reducer disposed therewithin for delivering rotary power to the drum shell at a determined region thereof. A mounting face system has a mounting face arrangement that receives components to be attached to alter the length of the motorized drum. The mounting face arrangement is disposed at an end of the motorized drum distal from the region where the reducer delivers power to the drum shell. The mounting face arrangement limits the flexure of the attachable components such that the deflection curve is continuous to reduce stress concentration.
