摘要： A reduction gear includes a case including a hollow cylinder having teeth on its inner wall; a ring gear having outer teeth meshed with the teeth of the cylinder, and inner teeth; and an eccentric gear assembly mounted in the cylinder and including a hollow eccentric shaft including rear and front eccentric sections, and first and second gears rotatably secured onto the rear and front eccentric sections respectively. Rotating an input shaft in a first speed will rotate the eccentric shaft to rotate the first and second gears around the inner teeth of the ring gear eccentrically, thereby rotating the output shaft in a second speed lower than the first speed. The invention has an increased number of meshed teeth between each of the first and second gears and the ring gear so as to distribute a radial load to more teeth in rotation.

摘要翻译： 减速机包括：壳体，包括在其内壁上具有齿的中空圆筒; 具有与所述气缸的齿啮合的外齿的齿圈和内齿; 以及安装在所述气缸中并且包括中空偏心轴的偏心齿轮组件，所述中空偏心轴包括后偏心部分和所述前偏心部分，以及分别可旋转地固定到所述后偏心部分和所述前偏心部分上的第一和第二齿轮。 以第一速度旋转输入轴将旋转偏心轴以使第一和第二齿轮围绕环形齿轮的内齿偏心旋转，从而使输出轴以低于第一速度的第二速度旋转。 本发明在第一和第二齿轮和环形齿轮中的每一个之间具有增加的啮合齿数，以便将旋转的径向载荷分配给更多的齿。
