Abstract
The utility model relates to a steering wheel assistance lifting motor of automobile, in particular to a high stability lifting motor of automobile. The utility model comprises a motor body and a reducer case. The reducer case comprises a case body, a case cover, and an input gear and an output gear arranged between the case body and the case cover. The output gear consists of a middle tooth part and a support part, the diameter of which is less than the outside diameter of the tooth part. The output gear is supported between the case cover and the case body in a rotary way through oily bearings arranged on both ends of the output gear on the support part. An oily rubber blanket, a ball bearing washer, a thrust ball bearing and a ball bearing washer are arranged between the inner ends of the oily bearings and both ends of the tooth part of the gear in turn; the oily rubber blanket touches the inner ends of the oily bearing. The utility model is capable of adjusting the axial displacement of the output gear; by adopting the utility model, the operation stability is improved. The utility model solves the problems of the prior lifting motors of automobile that the output gear of the reducer case is vulnerable to axial displacement which can not be adjusted automatically, and the operation stability is poor and so on.
Description
Technical field
The utility model relates to a kind of automobile lifting motor of steering wheel power-assisted, particularly a kind of high-stability car lifting motor.
Technical background
For alleviating the manipulation strength of driver, be provided for the automobile lifting motor of steering wheel power-assisted usually.Existing its speed reducer of automobile lifting motor mostly is following structure: the rotor shaft of motor body is connected with the input gear transmission of speed reducer, by reduction gear or direct and output gear engagement, output gear is supported between casing and the case lid by the bearing rotation of being located at its two ends the input gear again.The rotating shaft of supporting output gear in the motor reduction gearbox of said structure causes the axial position deviation of output gear easily because of the load that output gear is subjected to moves axially, and influences the stability of lifting motor operation.
Summary of the invention
The utility model purpose is to provide a kind of axial displacement that can align output gear automatically, can improve the automobile lifting motor of the stability of operation, solved that axial displacement easily takes place for speed reducer output gear that existing automobile lifting motor exists and can not self-regulating, problem such as the stability of operation is relatively poor.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: the high-stability car lifting motor, comprise motor body and speed reducer, speed reducer comprises casing, case lid and be located at casing and case lid between input gear and output gear, described output gear is made of the tooth portion of centre and the diameter supporting portion less than tooth portion external diameter, output gear is supported between case lid and the casing by the rotation of the oil-impregnated bearing on the supporting portion of being located at its two ends respectively, be provided with the oil-containing rubber pad successively between oil-impregnated bearing the inner and the output gear gear teeth portion two ends, the ball bearing packing ring, thrust ball bearing and ball bearing packing ring, the oil-containing rubber pad contacts with oil-impregnated bearing the inner.Wherein, be arranged on oil-impregnated bearing inner with output gear gear teeth portion two ends between oil-containing rubber pad, thrust ball bearing and the axial displacement that can adjust output gear automatically of ball bearing packing ring that the thrust ball bearing two ends are set, improve the stability that lifting motor moves; On the other hand, the oil-containing rubber pad also can replenish the lubricant oil of oil-impregnated bearing, to satisfy the lubricated needs of oil-impregnated bearing, reduces the wearing and tearing of oil-impregnated bearing and output gear, prolongs working life of the present utility model.
As preferably, described oil-containing rubber pad integral body contains many micropores, is soaked with lubricant oil in the micropore.The oil-containing rubber pad adopts microcellular structure, can comprise more lubricant oil, but when oil-containing rubber pad pressurized removal of lubricant, when the oil-containing rubber pad resiles, can absorb lubricant oil, thereby guarantee oil-impregnated bearing enough its lubrications of lubricant oil of oil-containing all the time.
Therefore, the utlity model has the axial displacement that to align output gear automatically, can improve the characteristics such as stability of operation.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model speed reducer.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: the automobile lifting motor, comprise motor body and speed reducer, as shown in Figure 1, speed reducer comprise casing 7, case lid 16 and be located at casing 7 and case lid 16 between input gear 12 and output gear 14, casing 7 is connected and fixed by plus screw 15 with case lid 16, rotor shaft 3 is in transmission connection with input gear 12, rotor shaft 3 ends are provided with plastics jacking block 2, plastics jacking block 2 ends are spheric structure and offset with screw 1 end, are provided with while and the idle pulley 13 of importing gear 12 and output gear 14 engagements between input gear 12 and the output gear 14.Wherein idle pulley 13 and input gear 12 are plastic gear, and output gear 14 is a metal gear.The plug 6 and the plug 5 of idle pulley 13 and input gear 12 and support idle pulley 13 and input gear 12 are rotatably connected, and plug 6 is directly fixedlyed connected with case lid 16 and casing 7 with plug 5.
Claims (2)
