The invention discloses an automobile engine oil pump belt wheel. The automobile engine oil pump belt wheel comprises an engine oil pump belt wheel body, wherein an assembly hole which is fitted withan assembly shaft is formed in a central position of the engine oil pump belt wheel body; the engine oil pump belt wheel body is of an integrated structure in powder metallurgy forming; a first concave cavity is formed in one side of the engine oil pump belt wheel body; a second concave cavity is formed in the other side of the engine oil pump belt wheel body the depth of the first concave cavityis greater than the depth of the second concave cavity; conical lightening holes are uniformly formed in the periphery of the assembly hole in the engine oil pump belt wheel body; the diameter of thelightening holes in a first concave cavity side is greater than the diameter of the lightening holes in a second concave cavity side; wheel teeth fitted with a transmission belt are formed at the periphery of the engine oil pump belt wheel body; grooves are formed between adjacent wheel teeth. The automobile engine oil pump belt wheel disclosed by the invention has the advantages that the structure is simple, and the automobile engine oil pump belt wheel is in one-step forming by adopting a powder metallurgy technology, is convenient to manufacture and is low in manufacturing cost; a part of axial force generated during a rotating process can be counteracted by adopting a non-symmetric structure; through the conical lightening holes, the gravity center is kept in the central line, and rotation is more stable.
Description
technical field [0001] The invention relates to a spare part of an automobile engine, in particular to an automobile engine oil pump pulley. Background technique [0002] As we all know, when the engine is working, cooling and lubrication are very important. Insufficient cooling or excessive cooling will cause adverse consequences, which will cause the engine to not work normally, reduce power, and shorten life; lack of lubrication between parts will aggravate the wear of parts, thus affect the overall life of the engine. [0003] The engine oil is the most important part of the lubrication system. The oil not only has a lubricating effect, but also can cool down the parts. The role of the oil pump is to provide power for the delivery of the oil. When the engine is running, the oil pump runs and passes The pulley transmits the driving force outward, so the reliability of the oil pump pulley is not only related to the operation of the oil pump and the delivery of oil, but wi...
