Problems solved by technology
[0003] This kind of torque limiter can only adjust the slipping torque of the torque limiter, and cannot realize the shifting function during the torque transmission process, and the structure is relatively complicated
Due to the mechanical transmission structure, sometimes the mechanical transmission structure may be stuck during the power transmission process, which may easily make the shifting not smooth.

Embodiment Construction
[0025] In conjunction with the accompanying drawings, the transmission device is specifically described by taking the application of the transmission device on a motor power take-off as an example.
[0026] The motor power take-off includes a housing 3, a stator 13 disposed in the housing 3, a rotor and a power output shaft 1, the rotor is arranged on a rotor bracket 12, and the rotor bracket 12 is sleeved on the power output shaft 1, and the power output shaft 1 is supported in the housing 3 by bearings, and the outer end of the power output shaft 1 protrudes outside the housing 3 .
[0027] A movable frame 4 is sleeved on the power output shaft 1 in the housing 3, and a spline structure with a mutual clearance fit is provided between the movable frame 4 and the power output shaft 1, and a circumferential to the transmission. A clutch structure is provided between the movable frame 4 and the rotor bracket 12. After the clutch structure is closed, power can be transmitted fro...

The invention discloses a transmission device of a power output unit, and the transmission device is used for realizing transmission of power. The transmission device structurally comprises a rotor bracket, wherein a movable frame sleeves a power output shaft; a clutch structure is arranged between the movable frame and the rotor bracket; the movable frame and the power output shaft are in circumferential transmission; a primary drive gear sleeves the power output shaft; the primary drive gear and the rotor bracket are in circumferential transmission; a reduction transmission mechanism is arranged between the primary drive gear and a secondary driven gear which sleeves the power output shaft; a one-way transmission structure is arranged between the secondary driven gear and the power output shaft; springs act on the movable frame to promote the clutch structure to close; a return type pushing mechanism is arranged between the movable frame and the power output shaft; and the return type pushing mechanism is used for promoting the movable frame to overcome elastic force of the springs to axially move for separating a clutch during large-torque transmission.
Description
technical field [0001] The invention belongs to the field of mechanical power transmission, and in particular relates to a transmission device applied to a power output device for transmitting power. Background technique [0002] A utility model patent (CN 202659757U) discloses a torque limiter for a transmission shaft, which includes an outer tapered sleeve, an inner tapered sleeve, a thrust ball bearing, a sleeve, an elastic body, a gland, and the outer tapered sleeve and the inner tapered sleeve to a certain The taper fit, the elastic body is installed between the sleeve and the gland, and the outer cone sleeve, sleeve, elastic body, and gland are connected together by bolts. The utility model adjusts the slipping torque of the torque limiter by adjusting the axial force applied by the bolt, and compensates the wear and deformation of the friction surface through the elastic body. Since the friction surface adopts a cone structure, the whole structure has a smaller rotati...
