MOTION TRANSMITTING DEVICES AND TOOTHED WHEELS FOR USE THEREIN

摘要

A motion-transmitting device, e.g. a torque converter, for transmission of rotary motion makes use of a toothed wheel in which each recess between adjacent teeth is a portion of an ovoid hole. A datum plate has ovoid holes equidistantly arranged about a centre eccentric with respect to the wheel. Connector pins engage with rolling motion the holes in the datum plate and the recesses between the teeth, entering into and out of engagement with the wheel as the wheel is driven eccentrically with respect to the datum plate. The number of pins and holes differs from, preferably by unity, the number of teeth. Of the three integers, wheel, eccentric and datum, one forms the input, one the output and the third is the fixed reference. IMR/MM/SW/BA2648
