Abstract
Electric motor of automobile component with double rolling bearing mechanism disclosed by the invention, including：Motor, the motor include that motor output shaft and electricity drive part, and electricity drives the revolution of member driving motor output shaft；One worm screw, worm screw is on the worm screw end of motor output shaft；One worm gear, the worm gear are connected with worm drive；One in order to assembling the deceleration body of worm and wheel；The worm screw end of its motor output shaft is by two roller bearings in the deceleration body.As a result of two rolling bearings, its radial clearance very little, so the snail rod ends bend of worm screw and motor output shaft will not be made when worm gear bears very big radial load, so can allow being engaged on its node of worm and worm wheel all the time, so as to ensure that transmission efficiency, the intensity of worm gear and worm screw is improve.
Description
Technical field
The present invention relates to electric motor of automobile technical field, especially a kind of electric motor of automobile component with double rolling bearing mechanism.
Background technology
The electric motor of automobile component with worm and gear that great majority are used at present, is mostly using a rolling bearing and one
Support of individual or two sliding bearings as transmission, in many cases, where at worm screw, stress is larger due to foozle not
Obtaining does not adopt big gap to coordinate, so that motor is when receiving more energetically, one end of worm screw becomes so as to there is worm shaft without support
Bent phenomenon, this bending can cause the engagement of worm and wheel not same on node, transmission efficiency occur and lower, and heating is increased etc.
Phenomenon, also results in the phenomenons such as worm tooth-surface damage when serious.
Content of the invention
The technical problem to be solved is for existing for the existing electric motor of automobile component with worm and gear
Above-mentioned technical problem and a kind of electric motor of automobile component with double rolling bearing mechanism is provided.
The technical problem to be solved can be achieved through the following technical solutions：
There is the electric motor of automobile component of double rolling bearing mechanism, including：
Motor, the motor include that motor output shaft and electricity drive part, and the electricity drives part and drives the motor output shaft
Revolution；
One worm screw, the worm screw is on the worm screw end of the motor output shaft；
One worm gear, the worm gear are connected with the worm drive；
One in order to assembling the deceleration body of the worm and wheel；
Characterized in that, the worm screw end of the motor output shaft by two roller bearings in the deceleration body.
In a preferred embodiment of the invention, two worm screw bullets are also configured with the worm screw end of the motor output shaft
Property positioning tapered sleeve, the flexibly positioned tapered sleeve of each worm screw is located between the worm screw and the rolling bearing.
In a preferred embodiment of the invention, multiple fabrication holes are configured with the flexibly positioned set of the worm screw, just
Fixed installation in worm screw Yu the worm screw end of motor output shaft.
In a preferred embodiment of the invention, Laser Welding is adopted between the worm screw end of the worm screw and motor output shaft
Connect or the mode of bonding is fixedly connected.
In a preferred embodiment of the invention, bullet is adopted in the rolling bearing outer end for driving part one end near the electricity
Property pressing plate is pushed down, to limit its axial gap.
As a result of technical scheme as above, the present invention compared with prior art, with following the characteristics of：
1). the supporting way that the worm screw end of motor output shaft is adopted two rolling bearings, two rolling bearings exist respectively
Worm screw is withstood on axial direction, for undertaking the axial force that transmits during dynamic turning.
2). multiple fabrication holes are configured with the flexibly positioned set of worm screw, be easy to the worm screw end of worm screw and motor output shaft
Fixed installation.
3) in two rolling bearings one be fixed on deceleration body, load worm screw after reinstall another rolling bearing, then
Pushed down with spring bearer plate, eliminate axial gap.
4) as a result of two rolling bearings, its radial clearance very little, so when worm gear bears very big radial load
The snail rod ends bend of worm screw and motor output shaft will not be made, so can allow worm and worm wheel all the time is engaged on its node
On, so as to ensure that transmission efficiency, improve the intensity of worm gear and worm screw.
5) coefficient of friction of rolling bearing is less than sliding bearing, and transmission efficiency, caloric value are few, when motor runs up
Produce heat and abrasion be few,
6) rolling bearing is without friction, after long-play, without axial gap, when motor is switched to reverse by forward direction without punching
Hit gap.
7) as two rolling bearings withstand worm screw respectively in the axial direction, the axial direction that transmits during dynamic turning assume responsibility for
Power, so worm screw just only needs to the torsion that can just meet transmission using less fixed end taken about the point of fixation with the worm screw end of motor output shaft
Require, on the flexibly positioned set of worm screw, be configured with multiple fabrication holes, can be solid by worm screw in the way of using laser welding or bonding
It is scheduled on the worm screw end of motor output shaft.
8) axial force of the invention only passes to rolling bearing, and solder joint is solely subjected to the power for rotating, so only needing to superficial weldering
By connecing intensity or adopt the bonding can also meeting intensity.
9) worm screw of the invention top footpath is big, so as to improve the intensity of the plastic gear coordinated with which.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is enlarged diagram at the I of Fig. 1.
