Description

The Car window electric machine transmission device

Technical field

The utility model relates to a kind of Car window electric machine transmission mechanism.

Background technology

Rotor and worm drive shaft in the tradition armature all are same axises, and above-mentioned way is very high to this requirement of beating, processed complex, and also the long more perpendicularity of axle ensures that with crooked just being difficult to motor use a period of time axle is easy to bending, causes motor oscillating.

As the patent No. is the electric rotor that the Chinese patent (notification number is CN2783616) of CN200520011155.1 discloses a kind of electric tool, comprise coil windings and commutator, it is characterized in that: the syndeton of described commutator and described coil windings is: on described commutator, the end of commutator segment has holding tank, weld by of the end clamping of described holding tank the tap of described coil windings, the electric rotor of this utility model electric tool is suitable for a large amount of productions, its structure, make, assemble quick and convenient, but its rotating shaft is whole one, so there is aforesaid defective.

Similar problem also is present in the Chinese patent that the patent No. is CN200520011746.9 (notification number is CN2783609), and it provides a kind of electric rotor of improved electric tool, comprise main shaft and the iron core that is contained on the main shaft, it is characterized in that: on the outer surface of described iron core, have the balance groove.On described main shaft, impeller is housed.

And self-locking also is to shake basic demand in the window electromechanics trade for shaking important indicator in the window motor performance.Self-locking is cut off the power supply of motor for when glass lifting arrives certain altitude, pushes glass with the power of 50Kg, and glass can not move downslide, plays certain self-locking effect.Traditional window motor transmission mechanism that shakes adopts the worm and gear transmission, when motor under out-of-work situation, external force acts on worm gear when passing to worm shaft again, just there is self-locking in itself, but their self-locking effects are bad, the someone has done some improvement for this reason, as the patent No. is that 200920187735.4 Chinese patent " Car window electric machine " discloses a kind of vehicle window transmission mechanism, it comprises end sealing and the open casing of the other end, be installed in a carbon brush holder of casing open end, be positioned at casing open end one side and be releasably attached to gear box on the casing, this gear box comprises a Worm-gear assembly, be positioned at the support of bearing and the rolling bearing that is positioned at the support of bearing with the casing cooperation place, it further comprises between casing open end and rolling bearing and the fixture of the described rolling bearing of axial restraint, adopt the technical scheme of this utility model, can guarantee the normal operation and the auto-lock function of motor, improve the functional reliability of Car window electric machine.But it mainly relies on worm and gear to realize self-locking, so the self-locking effect also needs further improvement, in addition, structure is also compact inadequately, is unfavorable for installing and using.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of compact conformation, self-locking effective at the above-mentioned state of the art, and be convenient to electric motor and separate assembling with reducing gear, avoided in the assembling process because of the bad problem of the long flexible concentricity that causes of axle.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of Car window electric machine transmission device, it includes rotor, worm screw rotation axis, the worm gear of motor, it is characterized in that: the rotor shaft of described motor detachably connects first driving member of claw coupling, the rear portion of first driving member is distributed with a plurality of claws along periphery, accordingly, the front end of worm screw rotation axis is provided with second driving member of claw coupling, the leading section of second driving member a plurality of pawl seats that along the circumferential direction distributed insert for claw and to connect;

And the claw coupling outside is with the roller bearing ring, and the roller bearing ring is provided with a plurality of roller shaft seats along the inner peripheral surface of own endoporus, and the built-in chamber in the roller shaft seat is communicated with the outer peripheral face and the endoporus of roller bearing ring, and being equipped with in the built-in chamber can be along mobile roller bearing inside and outside the radial direction;

Further, second driving member of claw coupling is provided with inboard conflict of mating surface and roller bearing and cooperates or break away between the pawl seat;

At last, the roller bearing ring is with bearing holder (housing, cover) outward again, and under worm screw rotation axis backward rotation state, roller bearing is promoted outer being moved by the mating surface on the pawl seat, keeps exposing the trend of roller bearing ring outer peripheral face, realizes reverse self-locking with the inner peripheral surface tensioner of bearing holder (housing, cover).

As improvement, described claw is to be convexly equipped with on the circumferential surface of first driving member, and accordingly, the roller bearing ring is having the cooperation draw-in groove between roller shaft seat on the inner peripheral surface.

Preferably, described claw coupling adopts the three-jaw connector, adopts three claws, and accordingly, the pawl seat also is three, and roller bearing and roller shaft seat also are three, and the setting that evenly distributes of concentric shafts circumference.

Further improve, described detachably the connection adopted the irregularly-shaped hole socket connection.Described irregularly-shaped hole is mounting hole, triangle hole, quadrilateral hole, five lateral opening or hexagonal holes.

At last, described draw-in groove adopts the circular arc draw-in groove.

Compared with prior art, advantage of the present utility model is: the armature that tradition is shaken the window motor is divided into two, assemble easier, divide the work refinement more, can accomplish that electric motor separates assembling with reducing gear, avoided bad in the assembling process because of the long flexible concentricity that causes of axle, cause problems such as motor is suppressed extremely, abnormal sound, and long service life, and increased the self-locking mechanism of compact conformation, simple in structure, assembling easily, in conjunction with the self-locking property of worm and gear and the unidirectional self-lock between roller bearing and the bearing holder (housing, cover), the self-locking effect is better.
