Motor-speed reducer for the simultaneous driving of two structures

摘要

The motor-speed reducer comprises an elongated tubular case (1) in which is disposed a motor (2) provided with two coaxial output shafts extending in opposite directions (4 and 6). Mounted on the end of each output shaft is an end portion (24) of a housing (22) of a speed reducer (18, 20). The end portion of the shaft has a worm (8, 10) which is engaged with an input worm wheel (32) of the speed reducer. The two speed reducers are preferably similar. A cassette (42) including an end-of-travel device and rotation detectors is mounted in the case (1) around the output shaft (6).
