Abstract

The invention belongs to the technical field of spiral gear manufacturing, and particularly relates to a manufacturing method for a spiral gear applied to a motor of an automobile skylight. A lathe cutting or thread rolling technology, which is complex, is mostly adopted for traditional machining and manufacturing of spiral gears, obtained spiral gears are poor in hardness and short in service life; for solving the problems above, the manufacturing method is provided. The manufacturing method comprises the following steps: S1, preparing raw materials and carrying out preparation; S2, guiding the raw materials into a smelting furnace for smelting; S3, carrying out smelting detection, regulation and control; S4, guiding melt into a mold for molding; S5, carrying out annealing and demolding; S6, carrying out performance detection; and S7, carrying out polishing. The spiral gear is made of multiple metal materials in a mixed manner, the hardness and toughness of the spiral gear are improved, and the service life of the spiral gear is prolonged; as manufacturing is conducted in a casting integrated forming manner, the manufacturing method is simple, and operation is convenient to carry out; and as oxygen is isolated during casting, oxidation is avoided, and the quality of manufacturing is improved.

Description

technical field [0001] The invention relates to the technical field of manufacturing helical gears, in particular to a method for manufacturing helical gears used in sunroof motors of automobiles. Background technique [0002] Cars are very common in life. In order to improve the comfort of cars, many cars are equipped with sunroofs on the top. The sunroofs are mostly opened by motor drive, and the motor drive uses a helical gear as a transmission mechanism. [0003] Traditional helical gears are mostly manufactured by lathe cutting or thread rolling technology, which is relatively complicated, has poor hardness and short service life. Contents of the invention [0004] The purpose of the present invention is to solve the disadvantages of traditional helical gears, such as lathe cutting or thread rolling, which are relatively complicated, poor in hardness, and short in service life. A manufacturing method of a helical gear for an automobile sunroof motor. [0005] In ord...
