Abstract

1525571 Driving arrangements for dynamoelectric machines HIGH TEMPERATURE ENGS Ltd 22 Aug 1975 [24 May 1974] 23393/74 Heading H2A [Also in Division F2] Two inputs of a differential device 10, e.g. of epicyclic or bevel gear type, are driven simultaneously through irreversible worm gears 8A, 8B by electric motors 3A, 3B, and the output of the differential drives a shaft 1, e.g. of a valve, through reduction gearing 11 ... 14 and a toothed sector 2, the arrangement being such that should one motor fail the shaft 1 is driven at half-speed by the other motor.
