Abstract
An automobile motor axial clearance damper is used for automobile motor with a reducer, characterized in that an elastomer is arranged in a cavity on the end of an output lead screw inside the reducer, the elastomer is provided inside with a hole embedded inside with a rigid positioning step, a rigid baffle is positioned between the elastomer and the end of the output lead screw. The utility model has the following advantages: when the output lead screw or an armature is abraded, the elastomer can automatically eliminate the clearance, rendering no axial clearance either in the motor's initial state or after a period of operation. The elastomer hole is coordinated with the rigid positioning step on the generator end cap or the reducer. When the generator receives a great axial force and then compresses the elastomer, the rigid positioning step will limit axial movement of the armature or the output lead screw, thereby protects the elastomer and meanwhile prevents significant axial chain movement caused by the great axial force.
Description
Technical field
The utility model relates to electric motor of automobile, particularly relates to a kind of device of eliminating electric motor of automobile end play.
Background technology
After there are end play in the armature shaft of conventional automotive seat motor or output screw mandrel, very big vibration noise can appear in the motor operation, if output screw mandrel end play excessive after, very big string also can occur with its connector and move, directly influence motor properties or fail safe, this moment, common practices was, adopt a screw, regulate end play by rotating screw, but after screw loosening or adjusting range wearing and tearing, its axial motion will increase obviously also.
Summary of the invention
The purpose of this utility model is to provide a kind of device that adopts elastic gel to eliminate electric motor of automobile end play, and elastomer can be eliminated the end play after armature shaft or the wearing and tearing of output screw mandrel automatically, end play can not occur after use a period of time.
For reaching above-mentioned purpose, the technical solution of the utility model is: device one elastomer in the cavity that output screw mandrel end is provided with in deceleration box, and there is a hole elastomer inside, sets a rigidity positioning step in the hole, the rigidity positioning step is made a monomer structure, or is to fixedly connected with deceleration box.Between elastomer and output screw mandrel end, a rigidity plate washer is housed, rigidity plate washer and output screw mandrel end be for contacting tight fit, and after exporting screw mandrel and wearing and tearing, elastomer can be eliminated the gap automatically, makes motor remain no end play.
Superior effect of the present utility model is:
1) the utility model is used to have the Car Motor Axial Clearance Dispelling Device of decelerator, and its elastomer can be eliminated the gap automatically after output screw mandrel or armature shaft wearing and tearing, makes motor all not have end play in initial condition and after using a period of time.
2) on the end cap of elasticity body opening and motor or the axial stiffness positioning step on the deceleration box cooperate; after motor is subjected to very big axial force compresses elastomeric; its rigidity positioning step will limit moving axially of armature shaft or output screw mandrel; play the elastomeric function of protection, avoid simultaneously because big axial force produces big axial motion.
Description of drawings
Figure is constructional device figure of the present utility model.
The number in the figure explanation
The 1-elastomer; 2-rigidity plate washer; 3-exports screw mandrel;
The 4-hole; 5-rigidity positioning step.
Embodiment
Below in conjunction with accompanying drawing structure of the present utility model is further described.
Accompanying drawing is the utility model and the electric motor of automobile enforcement figure that has decelerator.Wherein install an elastomer 1 in the cavity that output screw mandrel 3 ends are provided with in deceleration box, there is a hole 4 elastomer 1 inside, set a rigidity positioning step 5 in the hole 4, rigidity positioning step 5 is made for a monomer structure, or be and the deceleration box rigid connector, between elastomer 1 and output screw mandrel 3 ends, a rigidity plate washer 2 is housed, rigidity plate washer 2 with export screw mandrel 3 ends for contacting tight fit.
