Abstract

The utility model discloses a locknut for a motor. The locknut for the motor comprises a locknut core and a compress plate, a threaded hole is arranged at the center of the locknut core, an outer surface of the locknut core is a conical face, the conical face gradually enlarges along a screwing direction of the locknut core, a conical hole matching with the conical face of the locknut core is arranged at the center of the compress plate, and a plurality of through holes are uniformly distributed on the periphery of the compress plate along a peripheral direction. By adjusting the structure of the locknut, a preconceived locking effect of the locknut is achieved, and during constant operation and stopping of the motor, service life of the locknut is prolonged, and repair rate of the motor is lowered.

Description

A kind of motor is used locking nut
Technical field
The utility model relates to a kind of motor and uses locking nut.
Background technique
The working principle of nut is to adopt the frictional force between the nuts and bolt to carry out self-locking, but the reliability of this self-locking in dynamic load will reduce.Therefore when nut is used for motor, often take some proof measures in order to lock us, guarantee the reliability of nut check, wherein locking nut is exactly a kind of proof measures wherein.Because existing locking nut is an overall structure, locking effect is bad, needs the better motor of a kind of locking effect of research and development to use locking nut.
Summary of the invention
Goal of the invention: the purpose of the utility model is to overcome the deficiency of existing technology, and a kind of locking effect is provided, and good motor is used locking nut.
In order to solve the problems of the technologies described above, the utility model has adopted following technological scheme:
A kind of motor is used locking nut; It comprises locknut core and compression plate; The center of said locknut core is provided with tapped hole, and the outer surface of locknut core is a conical surface, and this conical surface becomes big gradually along the direction of screwing of locknut core; The center of said compression plate is provided with and the suitable cone shape hole of the external conical shape face of locknut core, along the circumferential direction is uniformly distributed with some through holes in the outer rim of compression plate.
In the utility model, further, the larger diameter end of said locknut core is provided with chuck, and the outer rim of said chuck is provided with some through holes, and said through hole is corresponding one by one with through hole on the compression plate.
In the utility model, further, said chuck and compression plate (2) weld together.
Beneficial effect: through the structure of adjustment locknut, make the locking effect of locking nut reach the effect of envisioning, in continuous operation of motor and stopped process, prolonged the working life of locking nut, reduced the motor repair rate.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is that A-A among Fig. 1 is to amplification view.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done explanation further.
As illustrated in fig. 1 and 2, the motor of the utility model comprises locknut core 1, compression plate 2 and chuck 3 with locking nut.
Center at locknut core 1 is provided with tapped hole, and the outer surface of locknut core 1 is a conical surface, and the size of this conical surface becomes greatly along the direction of screwing of locknut core 1 gradually, makes the profile of locknut core 1 be similar to a wedge-shaped blocks structure.The center of compression plate 2 is provided with and the suitable cone shape hole of the external conical shape face of locknut core 1, and compression plate 2 can be enclosed within on the cylindrical of locknut core 1 from the bottom to top like this.Chuck 3 is set in the larger diameter end of locknut core 1, and the shape of the interior hole shape of chuck 3 and the larger diameter end of locknut core 1 is suitable.Be respectively equipped with that quantity equates and through hole one to one in the outer rim of compression plate 2 and chuck 3.The quantity of through hole is 8 in the present embodiment, and they are evenly arranged along the circumferencial direction of compression plate 2 and chuck 3.
During use, earlier locknut core 1 is threaded on the motor, successively chuck 3 and compression plate 2 is enclosed within on the locknut core 1 from the bottom to top again, through bolt compression plate 2 and chuck 3 are fixed at last, and compression plate 2 and chuck 3 are welded together.Use just through bolt and these through holes, is fixed locking nut and wind wheel in motor the time; And regulate the gap between bonnet and the wind wheel through the tapped hole of locknut core 1 inner ring.
In motor operation course, compression plate 2 can prevent locknut core 1 to lower slider, and chuck 3 can prevent that locknut core 1 from rotating, and guaranteed the locking effect of locknut core 1.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
