Abstract

The invention relates to an oil pump. The oil pump includes an end cover, a base, a driving gear and a driven gear; the end cover is connected with the base to form an inner cavity, and the driving gear meshes with the driven gear and is arranged in the inner cavity; and the end cover and the base are formed by laminating and connecting a plurality of stamping plates. According to the oil pump, the integrated structure of the base and the end cover is formed by laminating and connecting multiple layers of stamping plate structures, and further, avoiding grooves for avoiding protruding structures such as burrs are manufactured on the corresponding side surfaces of the stamping plates. Based on the structural arrangement of the oil pump, the structural shape and dimensional accuracy of the base and the end cover in the oil pump can be ensured, so that the cooperation precision of the base and the end cover with other components is higher, meanwhile, the surface finish requirements are met, manufacturing is easy, the product cost is significantly reduced, the production efficiency becomes higher, the economic performance of products is improved, and the products are more competitive in price.

Description

technical field [0001] The invention relates to an engine oil pump. Background technique [0002] The gear oil pump generally includes an end cover and a base. After the end cover and the base are installed, a cavity is formed inside to accommodate the driving gear of the oil pump and the driven gear meshing with it. In addition, hydraulic oil passages with relatively complex shapes are generally provided on the end cap and the base. [0003] Since the driving gear and the driven gear are in the state of high-speed rotation in the above-mentioned internal cavity during operation, there are relatively high requirements for the dimensional accuracy and surface finish of the internal cavity. In addition, the mounting surface of the end cover and the base And the requirements for dimensional accuracy and surface finish of the mounting surface where the base is installed with the engine, gearbox, etc. are also relatively high. [0004] In addition, in order to meet some special...
