Abstract
The utility model discloses a kind of low-noise and scrape hydroelectric machine, comprise motor body assembly, reduction box assembly, worm shaft (5) end of the worm-and-wheel gear in the deceleration box (3) of described reduction box assembly and with reduction box assembly mutually assembling place is provided with plastics jackscrew (4), the armature shaft (9) of described motor body assembly upper and between the housing (8) and deceleration box (3) of motor body assembly place gap spring (6) is housed.The utility model can reduce the abnormal noise produced when scraping hydroelectric machine work, and the injection moulding process of plastics jackscrew is simple and feasible, can be widely used on the automobile electrical micro-machines such as automobile wiper motor, seat motor, air regulator lifting motor.
Description
Technical field
The present invention relates to a kind of motor, specifically relate to a kind of be applied to automobile scrape hydroelectric machine.
Background technology
Automobile wiper is the indispensable parts of automobile, and scrape the main element that hydroelectric machine is automobile wiper, hydroelectric machine is scraped by starting, through linkage (crank etc.) transferring power, brush assemblies is scraped in drive, produce scraping arm pressure simultaneously, by scraping blade, wiper is carried out to glass, thus sweep the foreign matter such as rainwater, dust on clean glass.At present, scrape hydroelectric machine and comprise motor body assembly, reduction box assembly, the housing of motor body assembly is connected with the deceleration box of reduction box assembly, the armature shaft of motor body assembly is connected with the worm shaft of the worm-and-wheel gear of reduction box assembly, worm-and-wheel gear is arranged in deceleration box, and reduction box assembly is directly positioned on car body.The deceleration box corresponding to worm shaft downstream that armature shaft is connected to worm-and-wheel gear is provided with a manhole, this manhole is mechanically linked a circular adjustment screw, there is screw thread and match with the manhole on deceleration box in the appearance of this adjustment screw, adjustment screw is by rotating the length regulating and enter deceleration box, but its length entered in deceleration box cannot obtain conservative control, good regulating action can not be played, be difficult to the abnormal voice that reduction reduction box assembly sends.This installation procedure is comparatively loaded down with trivial details in addition, can not get a desired effect.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and provide a kind of low-noise and scrape hydroelectric machine, be intended to easy for installation, reduce noise, improve and scrape water-based energy.
The present invention realizes by following technical solution: low-noise scrapes hydroelectric machine, comprise motor body assembly, reduction box assembly, in the deceleration box of described reduction box assembly and with the worm shaft end of the worm-and-wheel gear of reduction box assembly mutually assembling place be provided with plastics jackscrew, on the armature shaft of described motor body assembly and between the housing and deceleration box of motor body assembly, gap spring is equipped with at place.
After adopting the present invention, worm shaft is inserted in plastics jackscrew, and plastics jackscrew serves supporting role, armature shaft penetrates gap spring, under the effect of gap spring elongation and thrust, automatically regulate the position of armature shaft, thus serve the abnormal noise reducing and produce when scraping hydroelectric machine work.And the injection moulding process of this plastics jackscrew is simple and feasible, can be widely used on the automobile electrical micro-machines such as automobile wiper motor, seat motor, air regulator lifting motor.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and execution mode, the present invention is described in further detail.
Fig. 1 is the structural representation that low-noise of the present invention scrapes hydroelectric machine.
Fig. 2 is the structural representation of deceleration box in the present invention (having had plastics jackscrew).
Fig. 3 is the structural representation of deceleration box before injection moulding in the present invention.
Embodiment
Known with reference to Fig. 1, Fig. 2, low-noise of the present invention scrapes hydroelectric machine, comprise motor body assembly, reduction box assembly, in the deceleration box 3 of described reduction box assembly and with worm shaft 5 end of the worm-and-wheel gear of reduction box assembly mutually assembling place be provided with plastics jackscrew 4, on the armature shaft 9 of described motor body assembly and between the housing 8 and deceleration box 3 of motor body assembly, gap spring 6 is equipped with at place.The tapered shape of described plastics jackscrew 4.
As shown in Figure 1, motor body assembly comprises commutator 10 (i.e. commutator), armature winding 11, armature core 12 (i.e. rotor), magnetic shoe 13 (i.e. stator), housing 8, armature shaft 9 etc.; Reducer assemblies comprises worm shaft 5, worm gear 7, deceleration box 3 etc.Housing 8 and deceleration box 3 cooperation tighten together; Armature shaft 9 is connected with worm shaft 5; Worm shaft 5 and worm gear 7 (both engagements) composition worm-and-wheel gear (namely deceleration transmission is secondary).
As shown in drawings, the injection moulding process that described low-noise scrapes the plastics jackscrew of the deceleration box that hydroelectric machine adopts is: described deceleration box (for aluminium alloy) is after die cast, on described deceleration box 3, and with the joint, outer end of worm shaft 5, there is bellmouth 2 (inwardly), on described deceleration box 3, and with this bellmouth 2 adjacent, there is injecting hole 1 (outwardly), described injecting hole 1 be formed as between bellmouth 2 running through (connection), this deceleration box 3 is located by frock clamp, directly plastics entered in bellmouth 2 by injecting hole 1 by injection molding machine (passing through injection molding technology) and form plastics jackscrew 4, that eliminate follow-up installation procedure, be attached on deceleration box for the direct gained of injection moulding.
Described deceleration box is mechanically connected on housing, worm shaft 5 is inserted in plastics jackscrew 4 and (suitably adjusts, be inserted into suitable position), armature shaft 9 penetrates gap spring 6, under the effect of gap spring elongation and thrust, the position of automatic adjustment armature shaft, thus serve the abnormal noise reducing and produce when scraping hydroelectric machine work.Scrape hydroelectric machine operationally, can be subject to worm gear and give worm shaft an active force, worm shaft is meeting upwards play under the effect of this active force, and plastics jackscrew serves supporting role.Also playing correct guidance effect when scraping hydroelectric machine work simultaneously, reducing its radial amplitude of oscillation, and for holding mill part in the middle of friction pair.Armature shaft 9 and worm shaft 5 rotation can be touched with deceleration box, be worn and torn, and this plastics jackscrew hardness is low, both protects deceleration box, and protects worm shaft again, improves the useful life and durability of scraping hydroelectric machine.The present invention can be used for the wiper of the forward and backward windshield of vehicle, described vehicle, as motor vehicles such as passenger vehicle, car, trucies, scrapes the motor that hydroelectric machine is the wiper for vehicle, as permanent magnet DC motor.
