Abstract
The invention relates to an automatic axial end-play control device of a windscreen wiper motor. The automatic axial end-play control device of the windscreen wiper motor comprises a motor end cover and a casing. A rotor shaft is arranged in the casing, is sleeved with a plastic part positioning and control device, and is connected to the position of a bearing of the end cover through the plastic part positioning and control device; the plastic part positioning and control device comprises a base and a connecting end provided with a through hole; a torsion spring is arranged at the connecting end; two slope-shaped boss sections connected end to end are arranged on the base in the circumferential direction; the thickness of each boss becomes thinner in the forward 180-degree rotating direction, and becomes thicker in the reversed 180-degree rotation direction; the thickness, in the position of the bearing, of the end cover becomes thinner in the corresponding forward 180-degree rotation direction, and becomes thicker in the reversed 180-degree rotation direction; a connector used for installing the torsion spring is formed in the transverse thickest position in the 180-degreerotation direction of the end cover. The automatic axial end-play control device of the windscreen wiper motor is used in cooperation with an automatic plastic part positioning device to adjust the axial clearance of the rotor when the motor rotor is assembled and can automatically eliminate accumulated errors of all parts in the assembling process and compensate the clearance caused by mutual friction in the operating process.
Description
Technical field
The present invention relates to a kind of wiper motor, especially a kind of wiper motor axial endplay automatic control equipment.
Background technology
Current wiper motor rotor play in the axial direction in work all can not be effectively controlled, the gap of mutually wearing and tearing when the accumulated error during assembling between each parts and running and producing can make the positive and negative bidirectional rotation of wiper motor can not be controlled at all the time in the scope of designing requirement, the wiper of wiper can not be vacillated now to the left, now to the right in controlled area charactert, therefore need to improve electric machine structure, effectively control the axial endplay of this rotor.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the uncontrollable problem of existing wiper motor rotor axial play in the above-mentioned background technology, provide a kind of wiper motor axial endplay automatic control equipment.
The technical solution adopted in the present invention is: a kind of wiper motor axial endplay automatic control equipment, comprise electric motor end cap, casing, in casing, be provided with armature spindle, on described armature spindle, cover has the plastic position control device, and determine by this plastic the position of bearings that control device is connected to end cap, described plastic position control device comprises that base and offers the link of through hole, on link, be provided with torsion spring, on described base, join end to end in the circumferential direction of the circle and be provided with two sections domatic boss, boss thickness 180 degree are rotated in the forward by thick to thin, reverse 180 degree are thick by being thinned to, on described end cap, also be arranged to 180 corresponding degree is rotated in the forward by thick to thin in position of bearings, reverse 180 degree are thick by being thinned to, and in the horizontal thickness of 180 degree, have an interface that torsion spring is installed, this device coordinates the plastic automatic positioning equipment to regulate the end play of rotor when rotor assembles.After coordinating, this device make it along by thick, regulating gap to thin direction according to the stressed opposite direction twisting plastic control device of torsion spring, the torsion spring that assembles initial plastic thickness catches on admires into the thickest opening part of end cap, now twisting plastic has and thickly to thin direction, twists to casing end face and end cap end contact and coincide, torsion spring is thick along with plastic has in this process rotates and the power of tightening up gradually torsion spring to thin direction, simultaneously in assembling and use procedure under the effect at torsion spring, plastic has thin mutually the wearing and tearing when accumulated error between each parts and compensation running while moving to eliminate assembling to thick direction and the gap that produces, this device can be regulated displacement automatically, thereby can automatically control all the time the end play of rotor.
The invention has the beneficial effects as follows: wiper motor axial endplay automatic control equipment of the present invention has overcome the problem that current wiper motor can not be controlled the rotor axial play, the gap of mutually wearing and tearing when in the time of can automatically eliminating assembling, the accumulated error of each parts and compensation are turned round and producing, this device can be regulated displacement automatically, thereby can automatically control all the time the end play of rotor.
