Description

Technical Field

[0001] The utility model relates to the technical field of oil pumps, in particular to a three-claw positioning and mounting type oil pump. Background Art

[0002] The oil pump is a key component in the engine lubrication system. Its main function is to extract and pressurize the engine oil from the oil pan and then transport it to various parts of the engine that need lubrication, such as the crankshaft, connecting rod, camshaft, etc. The quality of its performance directly affects the service life and operating stability of the engine. An efficient oil pump can ensure the smooth circulation of the engine oil in the engine, reduce friction and wear, and lower the temperature of the engine during operation, thus ensuring the normal operation and good performance of the engine.

[0003] In the prior art, such as the utility model with the publication number CN210035005U, the utility model relates to the field of oil pumps, specifically an oil pump body, which includes a cylindrical pump body main body. A cylindrical first cavity is opened on the pump body main body, forming a bottomed and lidless cylinder; a first through hole for the rotation shaft to pass through is opened at the bottom of the cylinder, and the first cavity and the first through hole are coaxially arranged. By coaxially arranging the first cavity and the first through hole, and then arranging an eccentric ring in the first cavity, the upper end surface of the eccentric ring is recessed downward to form a stepped shape, and the outer rotor and the inner rotor are arranged in the cavity of the eccentric ring. When the inner rotor rotates forward, it drives the eccentric ring to rotate. After rotating a certain angle, the first stepped surface abuts against the limiting block; when the inner rotor rotates reversely, it drives the eccentric ring to rotate reversely. After rotating a certain angle, the second stepped surface abuts against the limiting block. Whether the inner rotor rotates forward or reversely, it ensures that the pump oil always enters from one channel and flows out from another channel, and the oil inlet groove and the oil outlet groove will not be interchanged.
