Abstract
The utility model discloses an automobile generator electric axle device, wherein, one end of the electric axle is an iron core and the other end thereof is a endless screw. A middle support bearing, a left support bearing and a right support bearing are respectively provided on the middle portion, the iron core and the endless screw of the electric axle. The middle and the left support bearings are both self aligning sphere sliding bearings, thereby bringing in high gearing efficiency, small abrasion, low noise and long life.
Description
Technical field
The utility model relates to a kind of armature shaft device of electric motor of automobile, and an end of armature shaft is an iron core, and the other end is a worm screw, is respectively equipped with middle supporting, left side supporting and right supporting middle part, iron core and the worm screw of armature shaft.
Background technology
Use on the automobile the permanent magnetic DC motor, the common ground of its structure is: behind the electrical power, worm screw armature shaft rotation, worm screw and gears engaged, and the rotation of driven gear shaft assembly, mechanical energy is exported by gear shaft, finishes electric energy and transforms to mechanical energy.Its armature shaft device is supported by three bearings, intermediate main bearing is the rolling ball bearing of overall radial sliding bearing or band dust cap, its major defect is: because three fulcrum structures of axle are redundant structure, the flexural deformation of issuable axle when intermediate main bearing is overall radial sliding bearing normal because error on making and work, bearing and axle surface can not obtain comprehensively evenly engagement, produce twisted phenomena, axle journal and bearing friction are bigger when making the armature shaft rotation, drive of motor efficient is reduced, power output and brake torque reduce when identical input power, and energy consumption strengthens; Intermediate main bearing be the overall radial sliding bearing for above-mentioned reasons, the bearing bearing wear is increased, after the bearing wear, the aperture is strengthened, and the gap between hole and the axle increases, can make motor vibration occur, increase motor noise, when the gap obviously increased, the distance between hole and the axle strengthened, worm screw and gears engaged worsen, and cause the gear inefficacy of skidding when serious; When middle base bearing is the rolling ball bearing of band dust cap, compare with sliding bearing, motor noise is bigger; The worm screw of three fulcrum structures of general axis end uses the plastic material sliding bearing, because this place's radial load is big, bearing is easy to wear, causes the distance between hole and the axle to strengthen, and worm screw worsens with gears engaged, causes the gear inefficacy of skidding in the time of seriously.
Summary of the invention
For overcoming the defective of prior art, the technical problems to be solved in the utility model has provided a kind of transmission efficiency height, wearing and tearing are little, noise is low, the armature shaft device of the electric motor of automobile of long service life.
The technical solution of the utility model is: the armature shaft device of this electric motor of automobile, wherein an end of armature shaft is an iron core, the other end is a worm screw, middle part, iron core and worm screw at armature shaft are respectively equipped with middle supporting, left side supporting and right supporting, and middle supporting and left side supporting are self-alignment formula spherical bearing.
Because the middle supporting of the armature shaft device of this electric motor of automobile and left side supporting are self-alignment formula spherical bearing, thus make the transmission efficiency height, wearing and tearing are little, noise is low, long service life.
Description of drawings
Fig. 1 is a structure chart of the present utility model;
Fig. 2 is the structure stress deformation pattern of Fig. 1.
Embodiment
With reference to the accompanying drawings, will be described in detail embodiment of the present utility model.
Fig. 1 is a structure chart of the present utility model.One end of armature shaft 5 is iron cores, and the other end is a worm screw, supporting 4 in middle part, iron core and the worm screw of armature shaft are respectively equipped with, left side supporting 6 and right supporting 3, and middle supporting 4 and left side supporting 6 are self-alignment formula spherical bearing.Right supporting 3 is composite self-lubricating sliding bearings.Also be respectively equipped with left axially mounting 7 and right axially mounting 2 at the two ends of described armature shaft, left side axially mounting 7 adopts the high-performance abrasion-proof plastics, and right axially mounting 2 adopts steel ball, reaches performances such as wear-resistant, low friction, the helical gear worm transmission pair is improved useful life, and noise reduces.
Fig. 2 is the structure stress deformation pattern of Fig. 1.Operation principle of the present utility model is: during machine operation, the worm screw of armature shaft drives helical gear (worm gear) rotation, and helical gear has individual radial effect power P to worm screw, and this power occurs bending and deformation the worm screw as the armature shaft of slender axles, and worm screw produces B in middle supporting place
1° the angle of inclination, owing to adopt self-alignment formula spherical bearing, bearing also tilts thereupon, makes bearing and axle surface energy obtain comprehensively evenly engagement, does not produce twisted phenomena, in like manner, self-alignment formula spherical bearing is also adopted in left side supporting, and bearing also tilts thereupon, makes bearing and axle surface energy obtain comprehensively evenly engagement, bearing wear reduces, and transmission efficiency improves.More wear-resisting composite self-lubricating sliding bearing is adopted in right supporting, this point has individual radial effect power P nearer from helical gear to worm screw, again because the armature worm shaft worm screw part diameter of axle is thinner, rigidity is relatively poor, the composite self-lubricating sliding bearing has and well prevents worm screw flexural deformation, because helical gear has individual radial effect power P to make the angle of inclination B of worm screw bending in the generation of style of work point to worm screw
2° very little, do not influence worm screw and helical gear normal engaged, transmission accuracy is higher, because the composite self-lubricating sliding bearing has performances such as self-lubricating preferably, wear-resistant, low friction, makes the raising in useful life of helical gear worm transmission pair again.Straight line 9 among Fig. 2 is that the armature shaft device does not have the state under the stressing conditions, and curve 8 is armature shaft device states after stressed.
The present invention can be applicable to various permanent magnetic DC motor supporting on the automobile as: scrape hydroelectric machine, skylight motor, seat motor, windscreen lifting motor etc., as embodiments of the invention skylight motor and wiper motor, implement the present invention--behind the two self-alignment formula spherical bearing devices of armature shaft three fulcrums of electric motor of automobile, the increase in useful life of helical gear worm transmission pair, efficient improve, noise reduces.The present invention has been applied to skylight motor (motor corporation of Cherry) and the wiper motor (Nanjing Fiat) supplied.
