<p>the gear box is for electric locomotives has an intermediate gear (2) meshing with a driven wheel (1) and connected to the wheel (1) and connected to the wheel shaft (12) by a rocker (4) so as to be movable arcuately about the wheel axis. By such movement the intermediate gear is engageable with drive pinions of different diameter mountable on a fixed shaft. The intermediate gear is mounted on a sleeve (202) supported on a pin (21) which has spring-loaded end collars (22, 23) between which the sleeve, the two arms of the rocker and the adjacent two housing walls (5, 52) are resiliently gripped, one of the housing walls (52) being flexible.</p> |
