一种带离合器的减速电机

Abstract

本实用新型涉及一种带离合器的减速电机，包括动力模块和离合器；离合器包括：离合轴，连接于动力模块的输出端；离合套，可轴向滑动地套设于离合轴的外周；弹性件，活动卡设于离合轴的外周且其一端抵接于离合套；其中，离合轴的外周设有至少一个限位凸块，离合套设有至少一个与限位凸块相匹配的限位槽；弹性件用于将离合套压向限位凸块，使限位槽卡接于限位凸块；离合套可通过克服弹性件的弹力以相对于离合轴旋转，使限位槽脱离限位凸块。本实用新型的减速电机受到外力冲击时，离合套可通过克服弹性件的弹力相对于离合轴旋转，使限位槽脱离限位凸块，让离合套在离合轴上打滑，避免损坏减速电机。

Claims

1. A geared motor with a clutch, characterized in that, Includes a power module and a clutch; the clutch includes: The clutch shaft is connected to the output end of the power module; The clutch sleeve is axially slidably sleeved on the outer periphery of the clutch shaft; An elastic element is movably engaged on the outer periphery of the clutch shaft, with one end abutting against the clutch sleeve; The clutch shaft has at least one limiting protrusion on its outer periphery, and the clutch sleeve has at least one limiting groove that matches the limiting protrusion. The elastic element is used to press the clutch sleeve against the limiting protrusion, so that the limiting groove is engaged with the limiting protrusion. The clutch sleeve can rotate relative to the clutch shaft by overcoming the elastic force of the elastic element, so that the limiting groove disengages from the limiting protrusion.

2. The belt-clutched reduction motor according to claim 1, characterized by, The contact surfaces between the limiting groove and the limiting protrusion are both arc surfaces or inclined surfaces.

3. The clutch-equipped gear motor of claim 1, wherein, One end of the clutch shaft is provided with a limiting ring and the other end is provided with a detachable limiting component. The limiting protrusion is located on the limiting ring, and the clutch sleeve and elastic component are located between the limiting ring and the limiting component.

4. The clutch-equipped gear motor according to claim 3, characterized by The limiting component includes a retaining plate sleeved on the outer periphery of the clutch shaft and a retaining spring secured on the outer periphery of the clutch shaft. The retaining plate abuts against the elastic component. The outer periphery of the clutch shaft is provided with an annular groove, and the retaining spring is secured within the annular groove.

5. The clutch-geared reduction motor of claim 1, wherein, The outer periphery of the clutch sleeve is provided with at least one connecting plane.

6. The clutch-equipped gear motor of claim 1, wherein, The elastic element is a metal spring.

7. The clutch-geared reduction motor of claim 1, wherein, The power module includes a motor body and a reduction gear assembly. The input end of the reduction gear assembly is connected to the output shaft of the motor body, and the output end of the reduction motor is connected to the clutch shaft.

8. The clutch-equipped gear motor of claim 7, wherein, The reduction assembly includes a fixed base, a transmission gear set, and a worm gear. The fixed base is disposed on the motor body, the transmission gear set is mounted on the fixed base, the worm gear is disposed on the output shaft of the motor body and meshes with the starting gear of the transmission gear set, and the ending gear of the transmission gear set is provided with a connecting shaft, which is the output end of the reduction motor.

9. The clutch-equipped gear motor of claim 8, wherein, The clutch shaft is provided with a mounting hole, and the connecting shaft is inserted into the mounting hole and can drive the clutch shaft to rotate.
