Embodiment Construction

[0029] The present invention is a special face gear shaper tool designed for face gear shaper processing. Taking a certain type of face gear shaper cutter as an example, the structure realization process of the gear shaper cutter is as follows: figure 1 shown. This implementation example is aimed at figure 2 The surface gear structure diagram shown, the steps to realize the gear shape cutter tooth structure are as follows:

[0030] (1) Known face gear teeth number N 2 , Face gear structure size (inner and outer diameter D 1 and D 2 ), number of pinion teeth N 1, pinion modulus m′, pinion pressure angle α′, pinion indexing arc tooth thickness s′, pinion precision grade, according to the principle of point contact surface gear transmission and surface gear and pinion are processed by the same tool , to determine the number of teeth N of the face gear shaper cutter s The range is than the number of pinion teeth N 1 1 to 5 more (it is not determined until step (8) whether ...

Abstract

The invention relates to a method for determining a face gear slotting cutter tooth form structure, which can determine a reasonable tooth number of a face gear slotting processing cutter based on the basic principles of face gear slotting gear processing and face gear meshing drive in comprehensive consideration of affects of different slotting cutter tooth number to the processing dimensions of a face gear and the drive meshing performance of a processed face gear, and further determines a face gear slotting cutter structure to be processed according to the tooth number of a pinion that is matched with the face gear. The face gear processed by the determined face gear slotting cutter tooth structure has good drive performance, the follow-up cost to reshape the face gear in order to improve the meshing performance of the face gear is saved, and meanwhile, the processing efficiency of the face gear is improved.

Description

technical field [0001] The invention relates to a novel tooth shape design method of a gear-shaping cutter for processing a gear-face gear, which is suitable for the design method of a gear-shaping cutter in the gear-shaping processing of a face gear. Background technique: [0002] At present, foreign technical data show that face gears can be processed by gear shaping, hobbing and grinding. Due to the strict confidentiality of foreign face gear processing technology, the processing methods and cutting tool design technology have not yet been mastered in China. , while domestic research on facing gears is still mainly focused on the design stage of facing gears, mainly including the research on the tooth surface equation of the face gear, the research on the contact analysis of the face gear, the research on the transmission stress of the face gear, the research on the elastohydrodynamic lubrication of the face gear and the research on the face gear Research on gear shaping ...
