Abstract

Gear drive has two pinions driven (11, 17) by a single motor (1) and both meshing with a rack (18) or large dia. gear. The torque on the pinions is equalised by an epicyclic gearing. The motor drives a carrier (5) for a set of bevel planets which mesh with two sun bevels (6, 12) arranged at opposite sides of the planets. The two sun gears are connected to drive the respective pinions in the same direction of rotation. The two sun gears are connected by a coupling having spring elements which preload the sun gears into opposite rotational directions, taking up backlash of both pinions.
