Description
Technical field
This utility model belongs to the technical field of steering wheel decelerator, is specifically related to the steering wheel decelerator of a kind of anti high overload.
Background technology
Traditional decelerator there will be bearing deformation under big overload situations, directly results in decelerator hydraulic performance decline, it is impossible to normally completes its task, and to ensure that its integral rigidity will certainly increase volume and the quality of decelerator.
Utility model content
In view of this, this utility model provides the steering wheel decelerator of a kind of anti high overload, it is possible to make steering wheel decelerator can under big overload normal operation, and the increase of quality volume is controlled minimum.
Realize the technical solution of the utility model as follows:
The steering wheel decelerator of a kind of anti high overload, including housing, sliding bearing, close ball bearing, output shaft, worm gear and worm screw；
The two ends processing of described worm gear has supporting axle, and the side processing of worm gear has circumferential toothing, and this toothing forms travelling gear；
One end processing of described worm screw has circumferential toothing, and this toothing forms travelling gear；
Worm screw is movably connected on housing by close ball bearing, the axis of worm screw is consistent with the overload direction of decelerator, the toothing of worm screw one end coordinates with the output shaft gear of motor, worm and wheel coordinates, the toothing of worm gear side coordinates with the gear on output shaft, the two ends of output shaft are movably connected on housing by sliding bearing, the supporting axle at worm gear two ends is installed sliding bearing, is movably connected on housing by sliding bearing.
Further, housing includes left shell and right shell body.
Beneficial effect:
1, this utility model adopts worm gear-endless screw, spur gear double reduction mode, and the benefit of this kind of ways of deceleration be overwhelming majority axles, and axis can with to transship direction parallel, it is to avoid the shearing of axle.
2, this utility model all uses sliding bearing with the bearing of overload direction orthogonal direction, so can increase bearing rigidity and lifting surface area, increase decelerator reliability under big overload condition.All using close ball bearing with the bearing of overload direction parallel direction, this kind of bearing can bear very big axial and radial load and the advantage with the little light weight of volume.
3, under equal intensity, reliability, reducer structure of the present utility model is compact, volume is little, light weight, it is possible to increase the space availability ratio of steering wheel.To shortening steering wheel length, alleviating steering wheel quality and have certain help.

Fig. 2 is the A-A profile of Fig. 1.
Wherein, 1-right shell body, 2-worm gear, 3-sliding bearing I, 4-output shaft, 5-sliding bearing II, 6-sliding bearing III, 7-left shell, the toothing on 8-sliding bearing IV, 9-worm screw, the close ball bearing of 10-, 11-gear on worm, 12-worm screw.
Detailed description of the invention
Develop simultaneously embodiment below in conjunction with accompanying drawing, this utility model is described in detail.
As depicted in figs. 1 and 2, this utility model provides the steering wheel decelerator of a kind of anti high overload, including housing, sliding bearing, close ball bearing 10, output shaft 4, worm gear 2 and worm screw 12.
Housing includes left shell 7 and right shell body 1.
The two ends processing of described worm gear 2 has supporting axle, and the side processing of worm gear 2 has circumferential toothing, and this toothing forms travelling gear；
One end processing of described worm screw 12 has circumferential toothing 9, and this toothing 9 forms travelling gear；
Worm screw 12 is movably connected on housing by close ball bearing, the axis of worm screw 12 is consistent with the overload direction of decelerator, the toothing 9 of worm screw 12 one end coordinates with the output shaft gear of motor, worm screw 12 coordinates with worm gear 2, the travelling gear of worm gear 2 side coordinates with the gear on output shaft 4, the two ends of output shaft 4 are movably connected on housing by sliding bearing II5 and sliding bearing III6, the supporting axle at worm gear 2 two ends is installed sliding bearing I3 and sliding bearing IV8, it is movably connected on housing by sliding bearing, the axis of worm gear 2 is perpendicular to the overload direction of decelerator, thus the rotating shaft moment of motor is transmitted the output shaft giving decelerator by decelerator by worm gear-endless screw, and the axis of worm screw is parallel to overload direction, prevent the deformation of close ball bearing.
According to the steering wheel decelerator that this technology manufactures, it is adaptable to transship greatly environment and compact conformation.Fully meet shell steering wheel and be subjected to big overload, reduce the instructions for use controlling partial-length.Increase explosive payload for guided cartridge, the demand of raising stability provides a method that.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
