Multi-purpose gear system has axis of rotation is in-line with the axis of rotation of the output drive minimizing mechanical losses

摘要

A multi-purpose gear drive system has a power-input cog (2) of the required ratio, whose axis of rotation is in-line with the axis of rotation of the output drive cog (3). The input and output cogs are linked by two or more further cogs by adjacent pinion gears which effect the necessary step-down or step-up ratio.
