摘要： A worm gear mechanism includes a worm, a torque-transmitting worm wheel meshing with the worm, and an auxiliary worm wheel disposed concentrically with the torque-transmitting worm wheel. The auxiliary worm wheel has a pitch circle diameter set to be greater than a pitch circle diameter of the torque-transmitting worm wheel and hence meshes with the worm in a meshing phase different from that of the torque-transmitting worm wheel. A screw thread provided on the worm actually meshes with teeth of the torque-transmitting worm wheel along a length defined as an actual meshing length. The screw thread has an effective length reduced to be approximately equal to the actual meshing length.
摘要翻译：蜗轮机构包括蜗杆，与蜗杆啮合的扭矩传递蜗轮，以及与扭矩传递蜗轮同心设置的辅助蜗轮。辅助蜗轮的节圆直径设定为大于扭矩传递蜗轮的节圆直径，因此与蜗轮啮合的啮合相位与扭矩传递蜗轮不同。设在蜗杆上的螺纹线实际上沿着定义为实际啮合长度的长度与扭矩传递蜗轮的齿啮合。螺纹的有效长度减小到近似等于实际的啮合长度。

摘要： A unit-type electric power steering system comprises a steering mechanism having a first shaft and a second shaft. The first shaft has an input shaft for connection to a steering shaft, and an output shaft connected to the input shaft for angular displacement relative thereto and for connection in driving engagement with the second shaft. The second shaft is disposed in a case for displacement therein. A torque sensor detects a steering torque of the steering mechanism, and an electric motor outputs a steering assist force to the first shaft in response to the steering torque detected by the torque sensor. The first shaft, the torque sensor and the electric motor define components integrated into a single unit for removable connection to and disconnection from the second shaft and the case as a single unit without independent connection and disconnection of any one of the components.

摘要： Provided is an electric power steering device in which the operation feeling is improved without a decrease in commercial value. A phase compensation unit performs a frequency shift on a compensation frequency band compensated by the phase compensation unit. The phase compensation unit performs phase-shift in the compensation frequency band through a frequency shift process, instead of an increase in compensation gain. Therefore, it is possible to minimize occurrences of minute vibrations and abnormal noise in the steering system including the motor that accompany an increase in gain, and to improve the operation feeling and commercial value.
