    摘要： An automobile-motor driving device equipped with speed reducer which has improved supply of lubrication oil to inside of the rolling bearings without sacrificing the function of the bearings, to reduce deformation in the rolling bearing outer ring. A parallel shaft gear speed reducer provides an automobile-motor driving device equipped with speed reducer. The parallel shaft gear speed reducer includes a plurality of gear shafts having two ends supported via rolling bearings fitted into bearing fitting holes in a speed reducer casing which houses the parallel shaft gear speed reducer. A groove in an inner circumferential surface of the bearing fitting hole into which the rolling bearing is fitted communicates between a space that houses the speed reducer and an inside space of the bearing fitting hole, at a location not crossed by the line of action of a load acting upon the rolling bearing due to the meshing of the gears.

    摘要： A rolling-element bearing transmission includes a rotor configured to rotate a shaft relative to a stator and a rotatable output ring that includes a first rolled-on surface element. The shaft includes at least one second rolled-on surface element, and the stator includes a third rolled-on surface element. First and second pluralities of rolling elements are located between the shaft and the stator and between the shaft and the output ring. Also, a transmission mechanism transmits a rotary motion of the shaft to the output ring with a speed reduction such that the output ring rotates at a lower speed than the shaft.

    摘要： A series elastic actuator includes a gear, a mounting recess formed in the gear, an elastic body provided in the mounting recess, an output body, a through-hole penetrating the gear, a shaft passing through the through-hole, a pair of bearings to radially support the shaft, and a pair of bearing mounting recesses to receive the pair of bearings. The gear is configured to rotate by a rotational power source. A rotation force of the gear is transmitted to the gear by the elastic body. The through-hole may extend in an axial direction, and the pair of bearings may be spaced apart from each other in the axial direction. The pair of bearing mounting recesses may be formed at opposite ends of the through-hole.

    摘要： A lubrication device for a vehicle drive-force transmitting apparatus that includes a casing, such that an interior of the casing is sectioned by a partition wall into a gear room and a motor room. A communication hole is provided through the partition wall to communicate between the gear room and the motor room. The communication hole has a gear-room-side opening and a motor-room-side opening, and opens at the gear-room-side opening in the gear room and at the motor-room-side opening in the motor room. The motor-room-side opening is located on an upper side of a bearing which supports a gear mechanism provided in the gear room and which is held in a bearing holding wall of the casing. The gear-room-side opening is provided in the bearing holding wall, and is in held in communication with a gap defined between an inner race and an outer race of the bearing.

    摘要： A gear transmission unit, particularly for a motor-vehicle, is provided with a forced lubrication system for lubricating rolling bearings and/or further inner components of the transmission unit. The unit is provided with one or more accessory elements in the form of lubricant distribution boxes. Each distribution box has a hollow body rigidly connected to the casing of the unit adjacent to a respective channel outlet which supplies a flow of lubricant under pressure. The hollow body defines an inner lubricant distribution chamber and has an inlet connected to the channel outlet and two or more outlets connected to further conduits for channels or chambers, for supplying the flow of lubricant under pressure in parallel to various components to be lubricated inside the transmission casing.
