Description
Technical field
The present invention relates to a kind of motor, and in particular to be a kind of lifter dynamo of autocar glass.
Background technology
The lifting of vehicle glass is completed by the work of lifter dynamo of autocar glass.The glass of automobile of prior art
Glass elevator motor, it is made up of motor component and reductor part, reductor part includes deceleration box and in deceleration box
The intermeshing transmission worm gear and geared worm, transmission worm gear set is working of plastics（Operating noise can be reduced）, geared worm
For steelwork, the right axle end of geared worm and the output axis connection of motor component, the centre of geared worm are supported by spherical bearing,
The left axle end of geared worm is vacantly set.Shortcoming is：When motor operation, rotor rotates, and drives transmission worm gear to rotate, band
After load, worm gear gives worm screw one reaction force, and this reaction force produces an axial thrust load and a radial component, works as load
After torque increase, this radial component can make motor shaft outwards produce elastic deformation, so that worm and gear meshing point changes,
After the change of this meshing point, electric efficiency is influenceed up to more than 20%, when meeting abnormal conditions, load torsion is uprushed, and motor occurs stifled
Turn, the outside deflection increase of worm screw, away from worm and gear meshing point, because worm gear is plastic material, so snail occurs in worm gear
Climbing tooth or shaving phenomenon are taken turns, so as to cause motor damage, failure mechanisms.
The content of the invention
In view of the deficiencies in the prior art, the purpose of the present invention is to be to provide a kind of simple in construction, can avoid the occurrence of worm gear
Climbing tooth or shaving phenomenon, guaranteed efficiency and the anti-worm screw sidesway lifter dynamo of autocar glass for improving service life.
The present invention is adopted the following technical scheme that to complete：
The lifter dynamo of autocar glass of anti-worm screw sidesway, is made up of motor component and reductor part, and reductor part includes
Deceleration box and the intermeshing transmission worm gear and geared worm set in deceleration box, transmission worm gear are working of plastics, are passed
Dynamic worm screw is steelwork, the right axle end of geared worm and the output axis connection of motor component, and the centre of geared worm is by spherical axis
Supporting is held, the left axle end of geared worm is vacantly set, it is characterised in that：The left axle end end of geared worm has arc surface, passes
The left axle end end alignment inclined-plane of dynamic worm screw, inclined-plane are slided with arc surface and offseted, and the incline direction on inclined-plane prevents geared worm
Left axle end is away from transmission worm gear.
Inclined-plane position is provided with wear-resistant pad, and wear-resistant pad is loaded in deceleration box in the semi-surrounding groove being provided with, semi-surrounding groove
Wear-resistant pad is obliquely installed with tipper bottom, its right end face of the wear-resistant pad after being obliquely installed forms the inclined-plane, wear-resistant pad
Left end face and semi-surrounding groove tipper bottom between be provided with thickness adjust pad
The inclined-plane and the angle of geared worm vertical direction are 6-9 degree.
Using the lifter dynamo of autocar glass of above-mentioned technical proposal, when loading moment increases in motor operation course,
Worm gear acts on reaction force on worm screw and increased, while its radial component increases, worm screw by this radial component influenceed to produce to
Outer elastic deformation, now inclined-plane can prevent the outside elastic deformation of worm screw, that is, the sidesway of geared worm is prevented, so that it is guaranteed that worm gear
Worm engaging point does not change, and ensures that electric efficiency does not change；When abnormal conditions occur, load torsion is uprushed, electricity
Stall occurs for machine, and same inclined-plane can prevent the outside elastic deformation of worm screw, so that it is guaranteed that worm and gear meshing point does not change, keep away
Exempt from worm gear climbing tooth or shaving phenomenon occur, ensure that motor is not damaged by, improve motor service life.
