Description

The oil pump is installed on the side of the third main bearing in the crankcase and is submerged in the lubriing oil. After starting, the oil pump sucks the lubriing oil. The oil port is connected with the oil passage of the upper crankshaft and the oil inlet of the coarse filter product. The pipe joint at the lower part of the oil pump is connected with the oil pipe and a fine filter. The oil pump housing is equipped with a driving shaft and a driven shaft. The lower end of the driving shaft uses a semicircular key and The steel wire clamp is fixed with the driving gear, the parts of the driving shaft in contact with the pump housing have radial oil storage grooves, the upper part of the driving shaft is connected with the distributor drive shaft through the cut groove, the transmission gear is fixed on the distributor drive shaft, and the transmission The gear meshes with the helical gear on the camshaft of the accessory mechanism to drive the oil pump. The driven shaft is press-fitted on the housing, and the driven gear is loosely sleeved on the driven shaft. When the driven shaft rotates, it drives the driving gear to rotate, and the driving gear The rotation drives the driven gear to rotate, and the rotation directions of the two gears are opposite. The volume of the oil inlet cavity increases due to the movement of the gear teeth in the disengagement direction, and a certain vacuum suction force is generated in the cavity. The oil pump sucks in from the oil inlet and fills the oil inlet cavity. When the gear rotates, the oil stored between the hydrogen teeth is brought into the oil outlet cavity. Since the gears on one side of the oil outlet cavity are engaged, the volume of the oil outlet cavity decreases and the oil pressure rises. , the oil is pressed out through the oil outlet and enters the friction surface of each moving part through the oil passage.

Characteristic

1.Transferring of oil to the engine essential parts of the engine under pressure.
2.Ease movement of the engine lubricant around the engine.
3.Offers direction to the movement of the oil through the galleries to various parts.
4.Helps to return the hot oil to the coolant oil in the reservoir.
5.Keeps the oil circulation within the engine constants.
