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.
