摘要： In an electric power steering device, a driven gear of a deceleration gear mechanism for transmitting rotation of an electric actuator for generating auxiliary steering power has a gear body made of a synthetic resin material. At least the outer periphery of a metal core ring is covered by the gear body. The gear body is molded and integrated with the core ring by injecting synthetic resin material into a mold, in which the core ring is inserted. A plurality of teeth, each of which has faces which run in the direction of the axis of rotation of the driven gear, are formed on the outer periphery of the core ring so as to be arranged at intervals in a circumferential direction. The synthetic resin material that constitutes the gear body is filled in the spaces between the teeth of the core ring.

摘要： A gearing radius of a worm wheel is set corresponding to a neighborhood region of a steering neutral position, in such a way as to be relatively large. Thus, backlash is made to be relatively small. This prevents noises from being produced when an automobile travels straight on a bad road. Conversely, the backlash is set corresponding to most of regions of steering angles, which are within the remaining region thereof, in such a manner as to be relatively large. Thus, increase in resistance torque is suppressed. This is realized by a simple configuration in which a bias portion is provided in a part of the profile of teeth. In a case where power is transmitted from an electric motor by a worm shaft and a worm wheel during a steering operation, noises are hard to be produced even when the automobile travels on a bad road.
摘要翻译：蜗轮的齿轮半径被设定为对应于转向中立位置的邻域，以相对较大的方式。因此，齿隙相对较小。这样可以防止汽车在恶劣的道路上直线行驶时产生噪音。相反，对应于处于其剩余区域内的转向角的大部分区域，以相对较大的方式设定齿隙。因此，抑制了电阻转矩的增加。这通过简单的构造来实现，其中在牙齿轮廓的一部分中设置偏置部分。在转向操作期间通过蜗杆轴和蜗轮从电动机传递动力的情况下，即使在汽车在恶劣的道路上行驶时也难以产生噪声。

摘要： A planetary gear apparatus whose gears are all constituted by continuous shifted gears. A backlash between the input sun gear and each of the input side planetary gears is adjusted by pressing a second carrier plate supporting each integrated pair of the input side planetary gears and the output side planetary gears and moving it in the axial length direction by a ball bearing by a screwing operation of an adjusting nut. A backlash between the output sun gear and each of the output side planetary gears is also adjusted by pressing the output sun gear and moving it in the axial length direction by the ball bearing by the screwing operation of the adjusting nut. Accordingly, the backlash of all meshing portions can be adjusted during or after completion of the assemblage.
