Transmission rack of toothed belt associated with elastic support board - which is compressed between pinion and rigid support bar to increase number of engaged teeth and transmissable force.

摘要

The rack of a rack and pinion drive is formed by a toothed belt (1) applied over a rigid bar guide (2) with an elastic band (3) in between that the belt conforms to the wheel over a larger sector and more teeth are engaged than with a rigid system. The distance (11) between the wheel axis (10) and the belt teeth (12) is less than the wheel radius (13) such that at least three teeth are fully engaged. $ USE/ADVANTAGE - Rack and pinion transmissions. The elastic support of the toothed belt allows greater number of teeth engagement and greater force transmission e.g. four times the force.
