Abstract
The utility model discloses a wiper motor including a motor, a reduction box, a worm wheel and a worm. The worm wheel and the worm are in mesh transmission and are arranged in the reduction box. The worm is connected with an output shaft of the motor. The wiper motor is characterized in that the reduction box is also provided with a back worm wheel arranged on a side back to the worm wheel. The back worm wheel is made of nylon material. The wiper motor provided by the utility model facilitates to guarantee the installation quality, reduces the abrasion of the worm wheels and the worm, reduces the operation noise and prolongs the service lifetime.
Description
[technical field]
The utility model relates to a kind of wiper parts, particularly a kind of improvement of rain shaving electrical machine invention.
[background technology]
Rain shaving electrical machine is a critical piece of windscreen wiping system for automobile.The structure of existing rain shaving electrical machine is generally: comprise motor, reduction box, worm gear and worm screw, worm gear and worm engaging transmission are located in the reduction box, the axle head of worm screw is connected with the output shaft of motor, and another axle head needs to be supported by the support holes that reduction box is processed in addition.Because the difficulty of processing of support holes is larger, easily there are deviation in the processing dimension of support holes and position, so installation quality that can not fine assurance rain shaving electrical machine, worm screw easily produces axial motion and radially wobbles during wiper work, wearing and tearing between the aggravation worm and gear, running noises is large, and shorten useful life.
[summary of the invention]
For the deficiency that background technology exists, the purpose of this utility model is intended to provide a kind of installation quality that is easy to guarantee, reduces the rain shaving electrical machine that worm and gear weares and teares, reduces running noises, increases useful life.
The utility model is implemented by following technical solution:
A kind of rain shaving electrical machine, comprise motor, reduction box, worm gear and worm screw, worm gear and worm engaging transmission are located in the reduction box, and worm screw is connected with the output shaft of motor, it is characterized in that: also be provided with the backrest worm gear in the described reduction box, the backrest worm gear is in the side setting of worm screw back to worm gear.
Rain shaving electrical machine of the present utility model, the axle head of worm screw is connected with the output shaft of motor, another axle head does not need to be supported by support holes, because worm screw just can access good location under the backrest effect of backrest worm gear, so just avoided the processing of support holes, be easy to guarantee the installation quality of rain shaving electrical machine, worm screw can not produce axial motion and radially wobble when making wiper work, keep the engaged transmission state good with worm gear, thereby reduce wear, reduce noise, increase useful life.
As a kind of preferred, the material selection nylon material of described backrest worm gear.The backrest worm gear is selected nylon material, and is lightweight, wear-resisting, can reduce noise.
[description of drawings]
Fig. 1 is structure chart of the present utility model.
[embodiment]
As shown in the figure, rain shaving electrical machine of the present utility model, comprise motor 1, reduction box 3, worm gear 2, backrest worm gear 5 and worm screw 4, worm gear 2, backrest worm gear 5 and worm screw 4 are located in the reduction box 3, worm gear 2 and worm screw 4 engaged transmission, backrest worm gear 5 be in the side setting of worm screw 4 back to worm gear 2, backrest worm gear 5 and worm screw 4 same engaged transmission, worm screw 4 is connected with the output shaft of motor 1, the material selection nylon material of described backrest worm gear 5.
Rain shaving electrical machine of the present utility model, because worm screw is well located under the backrest effect of backrest worm gear, be easy to guarantee the installation quality of rain shaving electrical machine, so worm screw can not produce axial motion and radially wobble during wiper work, keep the engaged transmission state good with worm gear, thereby reduce wear, reduce noise, increase useful life.
Claims (2)
