Embodiment approach

[0076] As a preferred embodiment, the actual parameters of the cycloid-involute spiral bevel gear are:

[0077]

[0078]

[0079] The processing parameters of the large wheel are determined according to the helix angle of the midpoint of the convex surface of the large wheel is ψ:

[0080] N C = N sin Γ = 54.7448

[0081]

[0082] S = A 2 + r C 2 - 2 A r C sin ( ψ - v ) = 316.97 mm

[0083]

[0084] q=ψ+η=61.3152°

[0085] The helix angle of the concave surface of the big wheel is:

[0086] R = ...

Abstract

The invention discloses a method for processing cycloid-involute spiral bevel gears on general digital control gear milling machines and a corresponding solid cutter, and belongs to the field of spiral bevel gear processing. According to the method, a large wheel can be processed by a double-sided method and a small wheel is processed by the double-sided method or a single-sided method. After a gear is subjected to heat treatment, the gear is shaved or ground. The cutter for processing the gear is integral; an installation structure of the cutter body on a machine tool is the same as a cutter installation structure used by the general digital control gear milling machines, and a soft cutting cutter head and a hard cutting cutter head used on the cutter and the assembly structure and method thereof are consistent with those used for the cycloid-involute spiral bevel gears. The cutter adopted in the method is simple in structure and easy to manufacture, and can perform processing on the general digital control machine tools without accessories or special designs, so the cycloid-involute spiral bevel gears can be easily promoted in industrial circles.

Description

technical field [0001] The invention relates to the field of spiral bevel gear processing, specifically a method for processing cycloid-involute spiral bevel gears and an integral cutterhead for processing such gears, which can be processed on a general-purpose milling machine. Spiral bevel gear. Background technique [0002] For the large-scale spiral bevel gears used in mining, metallurgy, building materials, energy and other industries, most foreign countries use the cycloid-quasi-involute system (Cycle-Palloid System) invented by the German Klingelnberg company in 1964. This tooth system adopts The double-body cutter head is processed by continuous hobbing on a special machine tool, and the gear is scraped with a cutter tooth equipped with a CBN cutter head after heat treatment. The advantage of this tooth system is that the adjustment of the contact area is simple and convenient, and no special software is required to calculate the gear cutting. It is very suitable for...
