Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] As shown in Figure 1, the processing of the new non-zero indexing bevel comprehensive displacement bevel gear can be processed by existing gear processing equipment, such as ordinary gear milling machines and gear grinding machines. Because the design feature of this transmission is that under the condition that the shaft angle Σ is constant, the sum of the comprehensive displacement coefficient composed of the radial displacement coefficient and the tangential displacement coefficient is not zero. That is to say, the sum of the circular tooth thicknesses of the large and small gears is not equal to the pitch π*m. Therefore, the process pitch cone must be taken on the meshing pitch cone when the transmission pair is meshed during calculation. The parameters input during the calculation must be the parameters on the pitch cone and pitch circle. ...

Abstract

The invention discloses a method for calculating machining parameters for a non-zero index comprehensive-modification bevel gear. In process, only pitch diameter, pitch modulus, pitch tooth profile angle and pitch theoretical circular tooth thickness need to be calculated according to parameters given on a designed drawing. Machining parameters of the bevel gear with a non-zero index comprehensive-modification tooth system are determined according to the parameters including the pitch diameter, the pitch modulus, the pitch tooth profile angle and the pitch theoretical circular tooth thickness. Speed and accuracy in calculation by the method are greatly increased, and the repeated calculating process is decreased. Technicians can calculate machine adjustment parameters required by the non-zero index comprehensive-modification bevel gear conveniently, quickly and accurately.

Description

technical field [0001] The invention relates to a calculation method for processing parameters of bevel gears, in particular to a calculation method for processing parameters of non-zero indexing cone comprehensive displacement bevel gears. Background technique [0002] The new type of non-zero indexing cone comprehensive displacement bevel gear transmission adopts the sum of the comprehensive displacement coefficient composed of the radial displacement coefficient and the tangential displacement coefficient to be non-zero (xh = xΣ+ 0.5*xtΣ*cosα≠0, where xΣ=x1+x2, xtΣ=xt1+xt2,) is designed and manufactured according to the principle. The transmission scheme obtained by optimizing the design of the gear pair transmission comprehensive performance with the four displacement coefficients (radial displacement coefficients x1, x2; tangential displacement coefficients xt1, xt2) as variables. Compared with the common zero-displacement bevel gear scheme, it has higher strength, lon...
