Embodiment Construction

[0053] According to the technical solution of the present invention, the applicant proposes a calculation method based on the shaving tooth modification meshing angle, and the specific implementation steps are:

[0054] Set the parameters of the gear being shaved to: the number of teeth Z 1 , normal modulus m n1 , normal pressure angle α of the pitch circle n1 , Pitch circle helix angle β 1 , Pitch circle normal arc tooth thickness The radius of curvature of the involute end point ρ max1 , the radius of curvature ρ of the starting point of the involute min1 , Shaving excess δ;

[0055] Set each parameter of the gear shaving cutter as: number of teeth Z 0 , normal modulus m n0 , normal pressure angle α of the pitch circle n0 , Pitch circle helix angle β 0, Pitch circle normal arc tooth thickness

[0056] When the staggered shaft cylindrical gear meshes without backlash, the pitch circle normal pitch P jn Normal arc tooth thickness with pitch circle of shaved gear ...

Abstract

The invention discloses a Stephenson-Newton iteration method based on gear shaving and modifying and engagement-angle calculating, which is applied to the technical field of the modifying of the gear shaver for the first time. The optimal solution of the engagement angle can be obtained by adopting the existing general approximate calculating method of the end surface engagement angle, the calculation error of the length of the engagement line, which is caused by the calculation error of the engagement angle, can be avoided, the modifying position of the gear shaver can be calculated more accurately, and the process effect of removing the concave shape of the shaved gear can be guaranteed effectively.

Description

technical field [0001] The invention belongs to the technical category of gear shaving technology in the gear manufacturing industry, and in particular relates to a calculation method based on gear shaving modification meshing angle. Background technique [0002] Gear shaving is an efficient traditional process for gear finishing, which has been widely used in gear production. However, when standard involute shaving cutters are used for gear shaving, different degrees of "sharpening" will occur near the pitch circle of the shaved gear tooth profile. The phenomenon of "concave tooth shape" affects the load-carrying capacity, transmission quality and service life of the gear. The correct shape modification of the shaving cutter is an effective way to solve the "concave tooth shape" of shaving teeth in the current production, that is, the concave modification in the middle area of ​​the standard tooth shape shaving cutter. Since the "concave tooth shape" of shaving is caused b...
