Abstract
The present utility model discloses a shake-proof device for motor. Said device in accordance with the present utility model comprises a motor front housing and a motor back housing which end surfaces are kept in an entire contact and fixed by screws, and is characterized in that: a concave ring corresponding to the shape of the motor front housing end surface and having a section width equal to that of the motor front housing end surface is set at a margin position of the motor back housing end surface; the upper end surface of a screw dochium at the motor front housing is lower than the motor front housing end surface, and a gap is formed therebetween and has a height same to that of said concave ring. Said concave ring and said gap facilitate formation of a dentation-like connection between the motor front housing end surface and the motor back housing end surface to avoid translations. The present utility model is capable of reducing effectively a possibility that a motor, especially a high power motor, is damaged due to shakes, and prolonging the service time of a motor, and facilitating installation of a motor ate the same time.
Description
Technical field
The utility model relates to a kind of motor vibration abatement, relates in particular to a kind of heavy-duty motor vibration abatement, belongs to motor accessory production field.
Background technology
Motor to be applied in current society very extensive, its power also differs widely according to actual needs, motor that power is bigger such as powerful fan motor, in use have bigger seismism, owing to fix by screw between motor fore shell and the motor back cover, so this vibrations can make holding screw be subjected to a bigger pressure.In existing all motors, motor fore shell end face contacts with the face face that motor back cover end face is plane formula, that is to say, if there is not holding screw, the motor fore shell can move arbitrarily in the direction vertical with motor with the motor back cover.Like this, the motor that installs is in use owing to vibrations produce shaking force, also will bear fully with the shaking force of motor vertical direction in the shaking force by holding screw, so might cause holding screw flexural deformation or fracture, and then cause dislocation between motor fore shell and the motor back cover, make rotor (being motor shaft) and stator (being coil) friction, thereby damage motor, shortened the life-span of motor.On the other hand, when holding screw was installed, because the motor fore shell can move arbitrarily in the direction vertical with motor with the motor back cover, so the hole is acquired a certain degree of difficulty, it was not very convenient installing.
Summary of the invention
The purpose of this utility model can avoid the holding screw of motor to be subjected to shaking force with the motor vertical direction with regard to being to provide in order to address the above problem a kind of motor vibration abatement, this device effectively.
For achieving the above object, the utility model is realized in the following manner:
The utility model comprises motor fore shell and motor back cover, contact fully between motor fore shell end face and the motor back cover end face, and fix by screw, be provided with the corresponding scrobicular ring of shape with described motor fore shell end face at the edge of described motor back cover end face, the cross-sectional width of described scrobicular ring is identical with the cross-sectional width of described motor fore shell end face; The upper surface of the screw seat of described motor fore shell is lower than described motor fore shell end face and between forms breach, and the height of described breach is identical with the height of described scrobicular ring.
Described scrobicular ring and breach make motor fore shell end and and formed a kind of connected mode that dentation connects that is similar between the motor back cover end face, so can avoid translation, just can avoid the motor fore shell to move arbitrarily in the direction vertical with motor with the motor back cover.
As best mode of the present utility model, the height of described scrobicular ring and described breach is between 0.2-2 centimetre.This height is adjusted accordingly according to different work of overall dimension of motor, can satisfy actual needs, can not influence the convenience and the aesthetic property of installation again.
The beneficial effects of the utility model are:
In sum, the utility model effectively reduce motor especially heavy-duty motor prolonged the useful life of motor because of vibrations damage the possibility of motor, be convenient to the installation of motor simultaneously.

Fig. 2 is the vertical profile schematic diagram after the utility model installs.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further concrete description:
As shown in Figure 2, the utility model comprises motor fore shell 1 and motor back cover 8, contact fully between the end face of the end face of motor fore shell 1 and motor back cover 8, and fix by screw, as shown in Figure 1, edge at the end face of motor back cover 8 is provided with and the corresponding scrobicular ring 6 of the end surface shape of motor fore shell 1, and the cross-sectional width of scrobicular ring 6 is identical with the cross-sectional width of motor fore shell 1 end face; End face and between that the upper surface of the screw seat 3 of motor fore shell 1 is lower than motor fore shell 1 form breach 5, and the height of breach 5 is identical with the height of scrobicular ring 6.
In actual applications, as shown in Figure 1, between motor fore shell bearing 2 and motor back cover bearing 9, connect by axle, scrobicular ring 6 and breach 5 make between the end face of the end face of motor fore shell 1 and motor back cover 8 and have formed a kind of connected mode that dentation connects that is similar to, so can avoid translation, just can avoid motor fore shell 1 to move arbitrarily in the direction vertical with motor with motor back cover 8, thereby avoided the dislocation between motor fore shell 1 and the motor back cover 8, also just avoided the axle between motor fore shell bearing 2 and the motor back cover bearing 9 to be damaged because of vibrations.
The height of scrobicular ring 6 and breach 5 is between 0.2-2 centimetre.This height is adjusted accordingly according to different work of overall dimension of motor, can satisfy actual needs, can not influence the convenience and the aesthetic property of installation again.
Of the present utility modelly focus between the fore shell end face of motor and back cover end face, being provided with a kind of connected mode that dentation connects that is similar to, if only change the shape or the size of the fore shell end face and the back cover end face of motor, all should be considered as invading patent right of the present utility model.
Claims (2)
1, a kind of motor vibration abatement, comprise motor fore shell and motor back cover, contact fully between motor fore shell end face and the motor back cover end face, and fix by screw, it is characterized in that: be provided with the corresponding scrobicular ring of shape with described motor fore shell end face at the edge of described motor back cover end face, the cross-sectional width of described scrobicular ring is identical with the cross-sectional width of described motor fore shell end face; The upper surface of the screw seat of described motor fore shell is lower than described motor fore shell end face and between forms breach, and the height of described breach is identical with the height of described scrobicular ring.
2, motor vibration abatement according to claim 1, it is characterized in that: the height of described scrobicular ring and described breach is between 0.2-2 centimetre.
