Embodiment Construction

[0016] A gear processing technology of the present invention is characterized in that: a gear processing technology is characterized in that: comprising the following steps:

[0017] (1) First of all, make a reasonable selection of gear materials;

[0018] (2) Formation of gear blanks: forgings, castings;

[0019] (3) Rough machining of gears: processing of tooth blanks, tooth shapes, and tooth ends, and removal of excess materials;

[0020] (4) Semi-finishing of gears: Shaping the gears;

[0021] (5) Gear heat treatment: preheating, quenching, tempering;

[0022] (6) Secondary finishing: benchmark the gear, finish the tooth shape and finish the product.

[0023] The gear material is alloy structural steel.

[0024] The preheating condition is 550-650°C / 40min.

[0025] The quenching condition is 900-950°C / 100min.

[0026] The tempering condition is 150-250°C / 3-4h.

[0027] The process of the invention is simple and clear. Rough machining, semi-finishing, and secondary f...

Abstract

The invention discloses a gear machining process. The gear machining process is characterized by comprising the following steps of (1), material selection, wherein a gear material is reasonably selected; (2), formation of a gear blank, wherein forging and casting are carried out; (3), rough machining of a gear, wherein gear blank machining, gear form machining and gear end machining are carried out, and redundant materials are cut off; (4), semi-finishing of the gear, wherein gear shaping is carried out on the gear; (5), heat treatment of the gear, wherein preheating, quenching and tempering are carried out; and (6), secondary finishing, wherein standardization is carried out on the gear, and the gear form is subject to finish machining to obtain a final finished product. The gear machining process has the advantages that the working procedures are simple and clear; and rough machining, semi-finishing and secondary finishing are carried out on the gear, so that the gear form is betterguaranteed, the machining efficiency is improved, the cost is saved, and meanwhile the quality of the gear is improved.

Description

technical field [0001] The invention relates to the technical field of transmission machinery, in particular to a gear processing technology. Background technique [0002] The application of gears in transmission has appeared very early. At the end of the 19th century, the principle of generative gear cutting method and special machine tools and cutting tools using this principle appeared one after another. With the development of production, the stability of gear operation was paid more attention. Gears are toothed mechanical parts that can mesh with each other, and they are widely used in mechanical transmission and the entire mechanical field. Modern gear technology has reached: the gear modulus is 0.004-100 mm; the gear diameter is 1 mm-150 meters; the transmission power can reach hundreds of thousands of kilowatts; the speed can reach hundreds of thousands of revolutions per minute; Second. [0003] The development of gear transmission in my country started from the ...
