Abstract
The utility model discloses a car pivoted window motor comprising a motor shaft, a bearing and a housing. The bearing sleeves the motor shaft and is in clearance fit with the motor shaft. The housing sleeves the bearing and is in interference fit with the bearing. The diameter of the front end of the inner hole of the bearing is less than the diameter of the rear end of the inner hole. According to the utility model, the design in which the diameter of the front end of the inner hole of the bearing is less than the diameter of the rear end of the inner hole is adopted, so the occurrence of the motor shaft locking condition can be prevented in the shell assembly process, accurate positioning does not need to be performed during installation, so the motor assembly speed can be improved, and at the same time, the motor production cost can also be reduced.
Description
Technical field
The utility model relates to a kind of motor, the motor specifically using on a kind of automobile window.
Background technology
The design of automobile window motor middle (center) bearing is that the shape of brearing bore and the peripheral shape of motor shaft are suitable at present; The shape of the external surface shape of bearing and internal side of shell face is suitable, bearing holder (housing, cover) is on motor shaft, casing is in bearing outside, in the time that shell assembles, compress bearing, the stressed brearing bore that causes of bearing lateral surface dwindles, after brearing bore dwindles, bearing " is embraced motor shaft ", the zero load of motor and load current increase, and then cause production qualification rate low, and motor assembling difficulty; Address this problem at present and need to carry out precision control to bearing and casing, production cost is high; Simultaneously because the wearing and tearing that also increased motor shaft and bearing " embraced motor shaft " by bearing, reduce the useful life of motor, also adopt at present the wearing and tearing that the mode of bearing and casing arranged in dislocation reduced to bearing and motor shaft, but compact car has requirement to the height of automobile window motor, limit and adopted the scope of application of producing in this way motor.
Summary of the invention
Goal of the invention: the utility model provides a kind of simple, effectively to prevent the generation of bearing locking motor shaft situation automobile window motor that assembles.
Technical scheme: the utility model discloses a kind of automobile window motor, comprise motor shaft, bearing and casing; Described bearing holder (housing, cover) on motor shaft and with motor shaft matched in clearance, described casing be enclosed within bearing outside and with bearing interference fit; The endoporus point diameter of described bearing is less than endoporus rear end diameter.In the utility model, adopt the endoporus point diameter of described bearing to be less than the generation that can prevent motor shaft locking situation when this design of diameter of endoporus rear end makes shell assembling, when installation without accurate location, improve the assembling speed of motor, also reduced the production cost of motor simultaneously.
Bearing described in the utility model preferably adopts stepped; Described bearing is made up of bearing front portion and bearing rear portion, and the interior diameter of described bearing front portion is less than the interior diameter at bearing rear portion; The outer dia of described bearing front portion is less than the outer dia at bearing rear portion.Stair-stepping bearing described in the utility model, makes bearing front portion be connected with motor shaft gap, and due to stair-stepping design, bearing is anterior not to be contacted with casing, when assembling, is not stressed, and has avoided the generation of bearing front portion with motor shaft locking situation; And the diameter of bore at described bearing rear portion is greater than the diameter of bore of bearing front portion, in the time of assembling, bearing rear portion is connected with casing close-fitting, and the bearing rear portion endoporus that is squeezed dwindles, but because bearing is stepped, bearing rear portion endoporus does not dwindle and can form locking phenomenon to motor shaft, be connected with casing because bearing only has bearing rear portion, bearing is anterior to be connected with motor shaft, has reduced friction area simultaneously, reduce wearing and tearing, improved the useful life of motor.
The face of internal side of shell described in the utility model and bearing rear portion interference fit.The interior diameter of described bearing front portion is less than the interior diameter 0.6-0.2mm at bearing rear portion; The outer dia of described bearing front portion is less than the outer dia 0.6-0.2mm at bearing rear portion.Bearing described in the utility model adopts the poor generation that can effectively avoid bearing rear portion locking situation of above-mentioned ladder, has reduced assembly difficulty simultaneously, without accurate controlling dimension, has accelerated the assembling speed of motor, has improved production efficiency.
Beneficial effect:
Compared with prior art, the utlity model has following advantage:
(1) automobile window motor described in the utility model adopts stair-stepping bearing, can effectively avoid the generation of bearing locking motor shaft situation, has reduced the zero load of motor, has reduced the load current of motor, effectively reduces energy consumption.
(2) automobile window motor described in the utility model adopts stair-stepping bearing, reduce the difficulty of assembling, accelerate the speed of assembling, without the precision of accurately controlling bearing, in the margin of tolerance of regulation, can both realize installation, reduced production and processing cost, improved the qualification rate of product, improved product is production efficiency simultaneously.
(3) in automobile window motor described in the utility model, adopt stair-stepping bearing, reduced the wearing and tearing of motor, improved the useful life of motor, further improved the quality of product.
Brief description of the drawings
Fig. 1 is the structural representation of automobile window motor described in the utility model.
Fig. 2 is the structural representation of automobile window motor middle (center) bearing described in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand following embodiment and only be not used in restriction scope of the present utility model for the utility model is described, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the amendment of the various equivalent form of values of the present utility model.
Embodiment
A kind of automobile window motor as shown in the figure, comprises motor shaft 1, bearing 2 and casing 3; Described bearing 2 is stepped bearing anterior 21 and the bearing rear portion 22 of being divided into, and the interior diameter of described bearing front portion 21 is less than the interior diameter 0.5mm at bearing rear portion 22; The outer dia of described bearing front portion 21 is less than the outer dia 0.5mm at bearing rear portion 22.
The annexation of above-mentioned each parts is as follows: described bearing 2 be enclosed within on motor shaft 1 and with motor shaft 1 matched in clearance, described casing 3 be enclosed within bearing 2 outsides and with bearing 2 interference fit; The endoporus point diameter of described bearing 2 is less than endoporus rear end diameter.
The motor assembling process of above-mentioned automobile window motor is as follows: after bearing packs casing into due to interference fit, bearing rear portion endoporus tightens, because bearing rear portion endoporus is greater than the anterior endoporus of bearing, can be to motor shaft locking, and bearing front portion is not connected with casing, can there is not equally motor locking situation.
