Problems solved by technology

[0006] The inventors of the present application have found that the above two methods of the existing braking device have certain defects, for example, for the method using friction force, the braking torque is small, and heat and dust are easily generated during the braking process. , has adverse effects on the operation of the motor. If this effect is to be reduced, the braking device needs to be placed outside the motor, but this will increase the volume of the power assembly; for the method of using the locking mechanism, if the structure of ratchet and pawl is adopted , you need to set two sets of ratchets and pawls to achieve two-way locking. The braking device is more complicated. If the structure of screw and gear is used, it cannot be installed inside the motor due to problems such as reduction ratio and space.

Description

technical field [0001] The present application relates to the electromechanical field, in particular to a braking device and a power assembly. Background technique [0002] In automation equipment, power components are usually used to provide driving force for the movable parts of the equipment. The power assembly can have a motor and a reduction device, wherein the reduction device can be connected to the output end of the motor's rotating shaft, and the reduction device can transmit the power of the motor's rotating shaft through its internal gear and other transmission components, and output the power from the output shaft. For power, the rotational speed of the output shaft of the speed reduction device may be lower than the rotational speed of the rotating shaft of the motor. [0003] The power assembly usually also has a braking device, which is used to stop the rotating shaft of the motor from rotating, so as to ensure the safety of the automation equipment during op...
