The invention discloses a method for preparing and processing an oil pump driving gear. The method comprises the following steps that a material of which the chemical components and the physical properties meet the requirements of technical parameters is selected, and hot die forging is performed to obtain a rough blank; an oil pump driving gear finished product is prepared from the rough blank according to technical parameter requirements; the oil pump driving gear finished product is checked and accepted, and unqualified semi-finished products are scrapped or reworked; and the qualified oilpump driving gear finished product is protected, packaged and warehoused. The method for preparing and processing the oil pump driving gear has the beneficial effects that the wear resistance, fatiguestrength, rigidity, hardness and toughness of the oil pump driving gear are improved, the overall strength of the oil pump driving gear is improved, the reliability of the oil pump driving gear is improved, and the service life is prolonged; and the use requirement of the oil pump driving gear is met, meanwhile, the fault probability of an oil pump is reduced, and the use cost is saved.
Description
technical field [0001] The invention relates to the technical field of oil pump active teeth, in particular to a method for preparing and processing oil pump active teeth. Background technique [0002] The oil pump is a light and compact pump, which can be divided into three categories: inline type, distribution type and single type. The oil pump is used to increase the oil pressure and ensure a certain amount of oil to force oil supply to each friction surface. Internal combustion engines widely use gear type and rotor type oil pumps. The gear type oil pump has the advantages of simple structure, convenient processing, reliable operation, long service life and high pump oil pressure, and is widely used. The rotor of the rotor pump has a complex shape and is usually pressed by powder metallurgy [0003] The driving gear of the oil pump is a gear that will rotate regardless of the working state. The gear power of the driving gear is directly derived from the crankshaft, and...
