Abstract
With a differential gearing having a spur gear construction, the compensating gears (31a, 31b) are installed in meshing pairs and are tightly enclosed by a housing (14) so that with meshing spur gears (22, 23) they can act as toothed pumps with pressure zones, with a locking moment being produced between the two driven shafts (2,3). A substantial increase in the locking moment is achieved in that the compensating gears constructed as pinions are disposed in a determined sequence on the circumference of the spur gears and also comprise along their face width partitions (32) which prevent a reduction in pressure along the toothing. As a result with an equal number of pinion pairs there is produced a number of pressure zones which is more than double and consequently there is an increase in the locking moment developed.
