Background technology
Automobile water wiper is the indispensable parts of automobile, and the purposes of wiper motor is for installing and driving Windshield Wiper assembly.At present, wiper motor is made up of motor body and drop-gear box assembly, and the rotating speed of motor, by worm shaft (also can be described as worm screw), worm gear reducer in drop-gear box, is then exported by worm-wheel shaft, thus drives automobile water wiper assembly system cloud gray model.Worm shaft in drop-gear box is directly connected with the armature shaft of motor, or on the end being directly assemblied in armature shaft, the other end of worm shaft is then integrated in the machining hole of drop-gear box.Because armature shaft is subject to the restriction of structure and size, the elongated round steel generally all adopting length-diameter ratio to be greater than 12 is produced; If excessive for the machining hole deviation of connecting worm axle supporting, the assembly quality of motor will be affected, and then cause worm shaft in wiper motor work, easy generation end float misalignment and radial runout, worm gear and worm shaft friction force are aggravated, wearing and tearing also aggravate and noise becomes large, thus shorten the service life of this motor.
In addition, it is well known that, in order to eliminate worm screw shaft runout and axial jump in prior art, such as: disclosed such in ZL 20092011337.7, in described deceleration matrix, increase a similar gear with the other end of the worm shaft in worm gear motor matrix, eliminate the axial jump and radial runout that produce when it runs, this structure not only increases drop-gear box volume and cost, and the operation of gear owing to newly increasing, not only increase the operating power of wiper motor, too increase noise when wiper motor runs simultaneously.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and provide a kind of can eliminate worm shaft radially wobble with end float misalignment, install easy to process without side on oscillation formula wiper motor.
The object of the invention is achieved through the following technical solutions: without side on oscillation formula wiper motor, comprise motor body, drop-gear box assembly, the drop-gear box of described drop-gear box assembly is built with intermeshing worm gear, worm shaft, this worm shaft is connected with the armature shaft of motor body, this worm gear is connected with worm-wheel shaft, that engages at described worm gear, worm shaft is equipped with a radiai adjustment element on the worm shaft of position, and the outer end of described worm shaft is equipped with an axial adjustment element; Described radiai adjustment element and axial adjustment element are contained on the drop-gear box of drop-gear box assembly respectively.
After adopting the present invention, effectively can eliminate radially wobbling and end float misalignment of worm shaft, realize without side on oscillation, and easy to process, ensure installation quality, can reduce and run noise, improve the service life of wiper motor.Radial direction, axial adjustment component structure for eliminating side on oscillation are simple, by adopting the processing technology of precise injection molding, one-mold multiple-member, greatly improving work efficiency, also reducing parts cost simultaneously.The motor adopting the present invention to be assembled, is particularly preferably applied in the driver train of vehicle Computer Aided Design, as the motor in wiper, electric glass lifter, skylight.
