The invention discloses an integrated speed reducer which comprises a motor, a speed reducer, a gland, a hollow shaft, an end cover and a shell, and the motor and the speed reducer share one shaft andare installed at the two ends of the hollow shaft. Wherein the motor and the speed reducer share a shell and a gear ring, a stator of the motor is fixed in the shell, three outer gears in the speed reducer are meshed with the gear ring and are arranged on three eccentric mechanisms which form eccentric angles of 120 degrees with one another, and the planet carrier upper cover, the planet carrierlower cover and the three outer gears are in positioning connection through bolts sleeved with hollow pin shafts, a plurality of bearings and locking parts. The motor and the speed reducer share the same shaft and the same shell, so that the integrated speed reducer is more compact in structure and more stable in operation, the size and the weight of the integrated speed reducer are reduced, and due to the arrangement of the three outer gears with the eccentric angles of 120 degrees, the corner precision of the speed reducer is improved, power transmission is more stable, the speed ratio is increased, and the output torque is increased.
Description
technical field [0001] The present application relates to the field of deceleration devices, in particular to an integrated deceleration device. Background technique [0002] As a mechanical transmission device, the speed reducer is widely used in many fields, and the small tooth difference reducer is a special planetary reducer with flexible structure and various application forms. In the integrated reduction gear, the motor and the reducer have their own shells, which are usually connected by two independent parts, and the two shells also need to be connected and fixed separately; most of the reducers with small tooth difference use two gears socketed in two eccentric Direction, and the design of the eccentric sleeve with an angle of 180 degrees between the two eccentric directions, in order to achieve the effect of increasing the reduction ratio and increasing the output torque. [0003] The inventors have found that in the related art, there are the following problems: ...
