Abstract
The utility model discloses a motor vibration absorption structure, which comprises a motor consisting of a motor stator, a motor rotor and a motor end cover (1), wherein the motor end cover (1) is provided with a bearing (4), a motor rotor shaft (5) is supported on the bearing (4), a vibration absorption rubber pad (2) is arranged between the bottom surface of the motor end cover (1) and the endface of the bearing (4), and a vibration absorption steel ball (6) is arranged between the bottom surface of the motor end cover (1) and the end face of the motor rotor shaft (5). The motor vibrationabsorption structure can bear instantaneous high-impact acceleration action of 30,000 grams, has the advantages of strong capacity of bearing instantaneous impact, long service life, simple structure,easy manufacture, compact vibration absorption structure and small volume, and is particularly suitable for being made into a high-impact resistant micro motor.
Description
Technical field
The utility model relates to a kind of motor vibration-proof structure, belongs to the motor manufacturing technology field.
Background technology
At present, electric machine structure of the prior art generally all is that Bearing Installation with the support rotor axle is on electric motor end cap, when rotor is subjected to impact load, the energy of its impact load all passes on the bearing by rotor axis of electric, and pass on the electric motor end cap by bearing, and then be delivered in the external system by electric motor end cap, the motor of this structure is because bearing will bear whole moment impact load and energy, therefore when the motor with these structures was used in the occasion of some moment impact acceleration very big (such as impact acceleration greater than 20000g), the bearing of these motors of the prior art just was easily damaged.Therefore electric machine structure of the prior art can not satisfy the needs of use.
The utility model content
The purpose of this utility model is: provide a kind of and bear that the moment impact ability is big, useful life motor vibration-proof structure long and simple in structure, easy to manufacture, to overcome the deficiencies in the prior art.
The utility model is achieved in that and comprises the motor of being made up of motor stator, rotor and electric motor end cap, bearing is installed on electric motor end cap, rotor axis of electric is supported on the bearing, between the end face of the bottom surface of electric motor end cap and bearing, be provided with rubber damping pad, between the end face of the bottom surface of electric motor end cap and rotor axis of electric, be provided with the vibration damping steel ball.
Be provided with groove and shrinkage pool on the inner bottom surface of above-mentioned electric motor end cap, rubber damping pad is installed in the groove, and the vibration damping steel ball is installed in the shrinkage pool.
Between the end face of above-mentioned rubber damping pad and bearing, also be provided with the matrix back-up ring.
Owing to adopted technique scheme; the utility model is by the improvement to existing electric machine structure; make motor pass through three kinds of modes in use with rotor; the energy delivery that is produced under the effect of HI high impact transient acceleration is in external system or directly be absorbed at motor internal, thereby has protected rotor and bearing not to be vulnerable to the damage of HI high impact transient acceleration effect effectively.Test through reality, do the time spent according to the utility model bearing moment 30000g high-impact acceleration, can effectively the part impact energy be carried out the oneself and absorb and reasonably the part impact energy is delivered in the external system, the utility model is operate as normal reliably still.Therefore, the utility model compared with prior art, not only have can bear that the moment impact ability is strong, long service life, advantage simple in structure, easy to manufacture, but also have vibration-proof structure compactness, advantage that volume is little.Structure of the present utility model is particularly suitable for the micromachine of anti-HI high impact.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Embodiment of the present utility model: at the motor of making anti-HI high impact, particularly during micromachine, preferably adopt structure of the present utility model to make: promptly comprise by conventional method make by motor stator, the motor that rotor and electric motor end cap 1 are formed, and on electric motor end cap 1, install bearing 4, rotor axis of electric 5 is supported on the bearing 4 by traditional approach, during making, electric motor end cap 1 preferably adopts stainless steel material to make, bearing 4 can directly adopt common narrow profile shaft of the prior art to hold, rubber damping pad 2 is installed between the end face of the bottom surface of electric motor end cap 1 and bearing 4 then, and the vibration damping steel ball 6 that installation is used as vibration damping between the end face of the bottom surface of electric motor end cap 1 and rotor axis of electric 5; For easy to install and use, also can on the inner bottom surface of electric motor end cap 1, produce groove 7 and shrinkage pool 8 during manufacturing, then rubber damping pad 2 is installed in the groove 7, vibration damping steel ball 6 is installed in the shrinkage pool 8; Convenient in order to adjust in use, a matrix back-up ring 3 is installed between the end face of rubber damping pad 2 and bearing 4 again.
When using the utility model; when rotor under the situation that the effect of HI high impact transient acceleration takes place; energy on the rotor at first is delivered to part energy on the electric motor end cap by bearing; secondly part energy is delivered on the rubber damping pad; cushioning effect by rubber damping pad; with this portion of energy decay and absorption; rubber damping pad will further be compressed simultaneously; when being compressed to rotor axial end contact buffering steel ball; energy remaining will be delivered on the electric motor end cap and by electric motor end cap by buffering steel ball and be delivered in the external system on the rotor; the energy delivery that rotor is produced in the effect of HI high impact transient acceleration by above-mentioned three kinds of modes is in external system or directly absorbed, thereby reaches the purpose of both protecting rotor also to protect bearing.
