Description
Technical Field
The utility model relates to an electromechanical device, concretely relates to motor shaft protection device.
Background
The motor plays an important role in various devices and fields as a power source of electric appliances or various machines. The motor shaft is an important part connected with the rotating part, the rotating rod or other parts can deviate in the rotating process, the connection part is loosened to generate larger vibration, so that the motor shaft can generate friction and fracture in the working process, and certain potential safety hazards are caused to influence the normal operation of equipment.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that not enough to above-mentioned prior art provides a motor shaft protection device, plays the guard action to motor shaft, reduces the skew and prevents its fracture and meet accident.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a motor shaft protection device, includes pivot body, casing, its characterized in that: the inside installation cavity that is of casing, casing head and tail both ends are equipped with the open slot that is used for placing pivot body both ends, and the pivot body passes through first bearing and second bearing and casing fixed connection, shells inner wall is equipped with four evenly distributed's spout, the both ends of spout are equipped with the stopper, and sliding connection has splint in the spout, the splint both ends are connected with first spring, the other end and the stopper fixed connection of first spring, the splint cup joint is on the pivot body, and splint keep away from being connected with a plurality of second springs on the side of pivot body, another terminal surface and the spout fixed connection of second spring.
The utility model has the characteristics as above: the pivot can produce eccentric radial force and axial force at the during operation and make the pivot take place the skew, the pivot can be cliied at the motor during operation to splint that set up in the casing, reduce the skew of pivot and then reduce the friction, thereby the protection pivot is not split, set up the vibrations that the spring can slow down splint and receive between splint and casing, set up the removal that the stopper can restrict splint in the spout, can protect the pivot body not receive external impact force and damage in arranging the pivot body in the casing.
The utility model discloses further setting is: the contact surface of the clamping plate and the rotating shaft body is arc-shaped.
The utility model has the characteristics as above: the arc-shaped contact surface can make full contact with the rotating shaft body.
The utility model discloses further setting is: and an elastic anti-collision strip is arranged on the contact surface of the clamping plate and the rotating shaft body.
The utility model has the characteristics as above: the elastic anti-collision strip can effectively slow down the direct impact of the rotating shaft on the clamping plate, and the service life of the clamping plate is prolonged.
The utility model discloses further setting is: a heat radiation fan is installed in the shell.
The utility model has the characteristics as above: the rotating shaft can generate heat during working, the rotating shaft is arranged in the shell and is not beneficial to heat dissipation, and the heat dissipation can be accelerated by installing the heat dissipation fan in the shell.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
As shown in fig. 1, motor shaft protection device, including pivot body 1, casing 2, 2 inside installation cavity 21 that is of casing, 2 end to end of casing both ends are equipped with open slot 22, the open slot 22 at 2 both ends of casing is arranged in at the end to end both ends of pivot body 1, pivot body 1 and casing 2 are fixed through first bearing 3 and second bearing 4, 2 inner walls of casing are equipped with four evenly distributed's spout 23, the both ends of spout 23 are equipped with stopper 9, stopper 9 is last to be fixedly connected with first spring 10, sliding connection has splint 5 in the spout 23, splint 5 cup joints on pivot body 1, splint 5 keeps away from and is connected with a plurality of second springs 6 on the side of pivot body 1, another terminal surface and the spout 23 fixed connection of second spring 6. The end face of the clamping plate 5 sleeved with the rotating shaft body 1 is an arc-shaped face, an elastic anti-collision strip 7 is arranged, and two heat-dissipation electric fans 8 are arranged on the inner wall of the shell 2.
During operation, put into casing 2 with pivot body 1 in, splint 5 are fixed cup joints on pivot body 1 circumference, and splint 5 reduces the axial skew of pivot body 1 when rotating, and splint 5 both ends are equipped with stopper 9 and have restricted the back-and-forth movement of splint, and splint 5 keeps away from pivot body 1 and serves the impact that the spring 6 that sets up and can convert the impact that splint 5 received into elasticity and slow down the impact. The motor inevitably generates a lot of heat during operation, and the heat dissipation electric fan 8 arranged in the shell 1 plays a role in heat dissipation.
