Abstract
The utility model discloses a low noise long -life car wiper, including motor body and deceleration box assembly, motor body includes stator, rotor and pivot, deceleration box assembly includes the worm wheel, the pivot be with worm wheel complex worm, the draw -in groove has been seted up in the pivot, it is equipped with the adjusting spring to add on the draw -in groove, one side cover of adjusting spring is equipped with antifriction bearing and step rotor axle sleeve. Compared with the prior art, the beneficial effects of the utility model are that: through obtaining the buffering after the joining of adjusting spring at the atress in the twinkling of an eye that the motor has just started, can be fine reduce the axial impact force of motor, the elasticity of spring can be fine simultaneously remedies the axle clearance of rotor motor because of working and result in for a long time to the EPT rubber material is adopted in the effect that improves the motor life -span and reduce motor noise, and elasticity and leakproofness are effectively improved, reaches the purpose of reinforcing durability, reduction noise.
Description
Technical field
A kind of auto parts machinery of this utility model is and in particular to a kind of low noise long-life automobile wiper.
Background technology
At present, wiper motor is made up of motor body and reduction gearbox assembly, and the rotating speed of motor passes through the snail in reduction box
Bar axle (alternatively referred to as worm screw), worm gear reducer, are then exported by worm-wheel shaft, thus driving automobile wiper assembly system to transport
OK.Worm shaft in reduction box is directly connected with the armature shaft of motor, or is directly assemblied on the end of armature shaft, and worm screw
The other end of axle is then integrated in the processing hole of reduction box, and the wiper motor according to commonly using in the market uses rotor
Axle two ends steel ball thimble design As-Is analysis, the defect that generally existing electric efficiency is low, noise is big.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, providing a kind of electric efficiency height, frictional force
Little, noise is low, good endurance, the automobile wiper of cost relative reduction.
For solving above-mentioned technical problem, the technical solution of the utility model is：
A kind of low noise long-life automobile wiper, including motor body and reduction gearbox assembly, described motor body includes
Stator, rotor and rotating shaft, described reduction gearbox assembly includes worm gear, and described rotating shaft is the worm screw with worm gear, in described rotating shaft
Offer draw-in groove, described draw-in groove adds adjustment spring, the side of described adjustment spring is set with rolling bearing and step turns
Sub- axle sleeve.
The moment stress that rain shaving electrical machine has just started is 3-5 times of normal operation in normal, frequently starts to electricity for a long time
The impulsive force of machine rotor axial direction can lead to rotor axially gap play thus leading in motor work process due to inertia
Produce abnormal sound, then can be buffered in the moment stress that motor has just started after the addition adjusting spring, can be very
The good impulsive force reducing motor axial direction, simultaneously the elasticity of spring can be very good to make up rotor electric machine and lead because working long hours
The axial gap causing, thus the effect improving electrical machinery life and lowering motor noise.
Preferably, described motor body and the sealing member of reduction gearbox assembly junction are rubber.
Common motor, the sealing member of motor body and reduction gearbox assembly is paper-board material, there is fragile, sealing not
The defect such as strong, using ethylene propylene diene rubber material, elasticity and sealing are effectively improved, and reach enhancing durability, reduce and make an uproar
The purpose of sound.
Preferably, a side of described adjustment spring and step rotor axle sleeve is all arranged with c-type jump ring.
Using suspended type elastic structure, armature spindle is increased draw-in groove, installs spring c-type jump ring additional and fix, one end does not stress,
Reduce frictional force, reducing energy consumption, increase delivery efficiency, delivery efficiency is up to 55% about, and the delivery efficiency of common electric machine is
45% about, accordingly can reduce stalloy quantity and enamel-cover number of wire turns simultaneously.Reach electric efficiency height, rub by such scheme
Wiping power is little, noise is low, good endurance, the purpose of cost relative reduction.
Compared with prior art, the beneficial effects of the utility model are：Can be in motor after the addition adjusting spring
The moment stress just having started is buffered, and can be very good to reduce the impulsive force of motor axial direction, the elasticity of spring is permissible simultaneously
Make up the axial gap that rotor electric machine leads to because working long hours well, thus improving electrical machinery life and lowering motor noise
Effect, using ethylene propylene diene rubber material, elasticity and sealing are effectively improved, and reach and strengthen durability, reduce noise
Purpose.
