Description
Technical Field
The invention relates to the field of motors, in particular to a self-locking mechanism applied to a rotating shaft.
Background
In most transmission machinery applications, it is desirable to keep the transmission component stationary when stopped, avoiding movement caused by external forces, such as the drive shaft of a motor, and therefore adding a self-locking mechanism to the transmission component to lock the transmission component.
In the prior art, the self-locking is realized through the friction ring sleeved on the rotating shaft, the friction ring is tightly wrapped on the rotating shaft to generate self-locking force, the rotating shaft rotates when the product works, the friction ring and the rotating shaft continuously generate friction force, after the product is used for a period of time, the friction ring has larger abrasion, so that the self-locking force of the product is weakened, and finally the self-locking force of the product is reduced.
Disclosure of Invention
The invention aims to solve the defects and provide a self-locking mechanism applied to a rotating shaft.
The object of the invention is achieved by: be applied to self-locking mechanism of rotation axis, including drive assembly and self-locking assembly, drive assembly's lateral surface has wrapped up in the shell, drive assembly includes stator core and pivot, stator core cover is established in the lateral surface of pivot, the both ends of shell all are equipped with the opening, the opening all covers and has closed the curb plate, the middle part of curb plate all is equipped with the hole of dodging that is used for dodging the pivot, the one end of pivot is equipped with the spiral position, self-locking assembly includes fixed shell and reducing gear shell, the reducing gear shell sets up the one end of keeping away from the spiral position in the pivot, the fixed shell cover is established in the lateral surface of reducing gear shell and is connected with the curb plate, it has the resistance filler to fill between fixed shell and the reducing gear shell.
In the above description, as a further scheme, a position of the speed reduction shell, which is close to the rotating shaft, is provided with a clamping position matched with the rotating shaft, and the speed reduction shell is connected with the rotating shaft through the clamping position. The reduction gear case is used for providing the effect of reducing speed.
In the above description, as a further scheme, the side plate and the shell are fixedly connected through bolts and nuts.
In the above description, as a further scheme, the rotating shaft is rotatably connected with the housing through a bearing.
The beneficial effects of the invention are as follows: through filling a resistance filler between fixed shell and deceleration shell, make the pivot produce resistance when arbitrary direction rotates to reach the effect of self-locking force, this structure is difficult for wearing and tearing, can long-time continuous operation, long service life.
