Description
Technical field
The utility model relates to a kind of aseismatic mechanism.Specifically, be used to prevent from making motor between its bearing outer ring and bearing pedestal medial surface, produce the aseismatic mechanism clashing into and rub and shake under operation by machining tolerance and shape position error.
Background technology
As everyone knows, the appearance of motor is long-standing, and it is widely used in all trades and professions as actuating unit.Motor wherein has a housing, housing two ends are provided with the end cap for pushing down bearing, rubbing surface of end cover center is all processed with for the circular pit with bearing fit, the oral area of circular pit all has gland, all there is the axis hole coordinated with armature spindle at the bottom of described hole and gland center, have bearing in axis hole, described armature spindle end is successively by stretching out outside corresponding end cap after the axis hole at the bottom of the axis hole on gland, bearing and hole.The motor application of said structure is the level of state fashion in horizontal occasion i.e. its armature spindle can, once the motor of this structure is installed in vertical, when being such as applied on elevator or staircase, owing to magnetic field can be produced after the stator energising of motor, have the effect of magnetic pull.Add the tolerance and shape position error that produce in bearing pedestal on the support of motor, front and rear cover and the rotor axis of electric course of processing, and the play that bearing enclose exists, make between armature spindle and bearing inner race, produce between the hole wall of bearing outer ring and circular pit and clash into and rub.Meanwhile, the electromagnet pull of stator can be subject at energising running rotor, cause armature spindle to have axial displacement and produce.All above-mentioned factors, not only can make motor produce vibrations and noise, also can shorten the useful life of motor.
Utility model content
Problem to be solved in the utility model is to provide a kind of motor and runs aseismatic mechanism.Adopt this aseismatic mechanism, when motor can be avoided to run, produce vibrations and noise, extend the useful life of motor.
The problems referred to above to be solved in the utility model are realized by following technical scheme:
Motor of the present utility model runs aseismatic mechanism and comprises electric machine casing, there is end cap at electric machine casing two ends, rubbing surface of end cover center has for the circular pit with bearing fit, the oral area of circular pit has gland, all there is the axis hole coordinated with armature spindle at the bottom of described hole and gland center, have bearing in axis hole, described armature spindle end is successively by stretching out outside corresponding end cap after the axis hole at the bottom of the axis hole on gland, bearing and hole.The hole wall medial surface being characterized in described circular pit there is circumferential recess, flexible bump protection ring in circumferential recess.
Wherein, described elasticity bump protection ring is indeformable rubber ring at one hundred and twenty degrees centigrade.
The width of described circumferential recess is greater than the diameter of section of elasticity bump protection ring, and the diameter of elasticity bump protection ring is greater than the degree of depth of circumferential recess.
In the on-compressed state, the diameter of described elasticity bump protection ring 0.1 ~ 0.2mm larger than the degree of depth of circumferential recess.
Further improvement of the utility model scheme is, has stiffness spring pad at the bottom of the hole of described circular pit and between bearing.The unilateral along the circumferential direction undulate of described stiffness spring pad.
Wherein, described stiffness spring pad is spring steel pad.
Take such scheme, there is following problem:
As can be seen from the above scheme, due to the hole wall medial surface of described circular pit being processed with circumferential recess, be provided with elasticity bump protection ring in circumferential recess, this elasticity bump protection ring is indeformable rubber ring at one hundred and twenty degrees centigrade.Can not be out of shape at one hundred and twenty degrees centigrade, aging, to avoid when motor runs between armature spindle and bearing inner race, produce between the hole wall of bearing outer ring and circular pit and clash into and rub, not only effectively reduce vibrations when motor runs and noise, and extend the useful life of motor.Again due at the bottom of the hole of described circular pit and be provided with stiffness spring pad between bearing, the axial endplay that the axial magnetic pull that motor is subject in running causes and shake can be weakened by the elastic deformation of stiffness spring pad, thus the vibrations that reduce further when motor runs and noise, extend the useful life of motor.

Fig. 2 is the I point enlarged diagram of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, motor of the present utility model runs aseismatic mechanism and comprises electric machine casing 1, described electric machine casing 1 is cylindric, its two ends are provided with end cap 6, end cap 6 medial surface center is processed with the circular pit for coordinating with bearing 3, the oral area of circular pit is fixed with gland 7, and at the bottom of described hole and gland 7 center is all processed with the axis hole coordinated with armature spindle 5, is provided with bearing 3 in axis hole.Described armature spindle 5 end is successively by stretching out outside corresponding end cap 6 after the axis hole on gland 7, bearing 3 and the axis hole at the end, hole.Because friction, shock produce vibrations and noise when running for avoiding motor, extending the useful life of motor, the hole wall medial surface of described circular pit being processed with circumferential recess, in circumferential recess, being embedded with elasticity bump protection ring 2.Described elasticity bump protection ring 2 is indeformable rubber rings at one hundred and twenty degrees centigrade.
Wherein, the width of described circumferential recess is greater than the diameter of section of elasticity bump protection ring 2, and the diameter of elasticity bump protection ring 2 is greater than the degree of depth of circumferential recess.
In the on-compressed state, the diameter of described elasticity bump protection ring 2 0.1 ~ 0.2mm larger than the degree of depth of circumferential recess.
Because friction, shock produce vibrations and noise when running for avoiding motor further, extending the useful life of motor, at the bottom of the hole of described circular pit and between bearing 3, being provided with stiffness spring pad 4.This stiffness spring pad is spring steel pad, its unilateral along the circumferential direction undulate.
