Problems solved by technology

Although this kind of motor cover solves the lubrication problem of the wiper motor reduction mechanism to a certain extent, it has the direct sliding contact between the top block on the extrusion column and the gear, which produces sliding friction. The deceleration mechanism is overheated, which affects the service life. In addition, its lubricating oil can only flow out in one direction to lubricate the gear device and cannot recycle the lubricating oil, resulting in the need to add lubricating oil frequently, which is inconvenient to use

Abstract

The invention discloses a bottom pressurization oil supply type self-lubricating windshield wiper motor. The motor comprises a gear box body, a box body upper cover, an oil bottom groove, a driving motor, a driving turbine, a driven gear, a transmission worm, an atomizing nozzle and a pressurizing plunger pump. The oil bottom groove is connected to the bottom of the gear box body, and an oil return hole is arranged in the gear box body. The driving turbine is engaged with the transmission worm and the driven gear, the driving turbine is provided with an eccentric connecting portion, and a central axis of the eccentric connecting portion and the central axis of the driving turbine are not located on a same straight line. The pressurizing plunger pump comprises an oil inlet end, an oil outlet end and a piston, one end of the piston is connected with the eccentric connecting portion, the oil inlet end is connected with an oil storage cavity, and the oil outlet end is connected with the atomizing nozzle. Lubricating oil can be recycled, interval time for adding the lubricating oil is prolonged, and use is more convenient. Meanwhile, the lubricating oil is converted into mist so that acontact area of the lubricating oil can be increased, a lubricating range is wider, a lubricating effect is better, and a service life of the self-lubricating windshield wiper motor is prolonged.

Description

technical field [0001] The invention relates to a self-lubricating wiper motor of a bottom pressurized oil supply type. Background technique [0002] The invention patent with the patent number of 201910046308.2 discloses a motor cover of a wiper, which includes a motor casing, and a wiper gear device is arranged inside one end of the motor casing, and a push rod is arranged on the wiper gear device. A motor sealing cover is fixed on the top of the motor casing, and a fixing plate is fixed inside the motor sealing cover. An oil storage chamber is formed between the fixing plate and the inside of the motor sealing cover, and an oil discharge device is arranged in the oil storage room. The oil discharge device includes a first fixed ring, a second fixed ring, a first elastic device and a squeeze column, a first circular through hole is opened on the top of the fixed plate, and a second circular through hole is arranged on the motor sealing cover. shaped through hole, and the ...
