<P>PROBLEM TO BE SOLVED: To take out second and third rolling bearings from a housing along with thrust transmitting parts only by extracting input shafts after detaching a case cover to improve maintainability, and to suppress noise and damage of the bearings by dispersing a load acting on the rolling bearings to a plurality of members, firmly supporting the rolling bearings, and reducing deviation of rotational axes. <P>SOLUTION: Front sides of pinions 15, 19 are rotatably supported on a first case 4 via first ball bearings 37b, 38b, and rear sides of the pinions are rotatably supported on a second case 5 via the second ball bearings 37c, 38c. Rear sides of the input shafts 12, 16 are rotatably supported on the case cover 6 via the third ball bearings 37d, 38d. Clutches 14, 18 and input gears 13, 17 are stored in the case cover, sleeves 39, 40 are interposed between the first ball bearings and the front sides of the pinions, and the pinions are allowed to be inserted/extracted to/from the sleeves. <P>COPYRIGHT: (C)2013,JPO&INPIT |
