Gear oil pumps are characterized by reliable operation, simple structure, convenient manufacturing and high oil pressure, so they are widely used.
When the engine is working, the driving gear on the camshaft drives the transmission gear of the oil pump, which causes the driving gear fixed on the driving gear shaft to rotate, thereby driving the driven gear to rotate in the opposite direction, and the oil from the oil inlet cavity along the backlash And pump wall to the oil outlet cavity. In this way, a low pressure is formed at the oil inlet cavity to generate suction, and the oil in the oil pan is sucked into the oil cavity. Due to the continuous rotation of the main and driven gears, the oil is continuously pressed to the required parts.
