Face gear tooth scraping machining method

Abstract

The invention relates to a face gear tooth scraping machining method. A face gear is machined by adopting a method of using a cutter to cut a workpiece, the cutter and a workpiece are in spatial staggered axial surface worm transmission, namely the cutter and the workpiece form a spatial cylindrical surface worm pair, and therefore, tooth scraping machining of the face gear is realized. The face gear tooth scraping machining method inherits the technical advantages of tooth scraping of the cylindrical gear and possesses higher production efficiency and machining precision. According to the face gear tooth scraping machining method, enveloping of the tooth surface is achieved through the space surface worm transmission principle, and materials are removed by adjusting offset of the cutter and the workpiece in the machining process.

Description

technical field [0001] The invention relates to a processing technology of a face gear, and more specifically, relates to a method for processing a face gear with tooth scraping. Background technique [0002] Face gears are used to transmit force and motion between intersecting and staggered shafts. They are widely used in automobiles, engineering machinery, and aerospace equipment. They have the advantages of strong bearing capacity, insensitivity to installation errors, and adjustable contact areas. [0003] The current front gear technology mainly focuses on gear shaping, rolling-grinding (worm tool), milling-grinding (disc tool): gear shaping is the most commonly used processing method for face gears, and cutting is realized based on the meshing of simulated large and small gears. By using The number of teeth of the gear shaping cutter is more than that of the small wheel to achieve local contact, and can process all types of face gears, with good process flexibility; th...

Problems solved by technology

[0004] The above analysis shows that the face gear shaping process is the most flexible at present, and can manufacture inner and outer bevel gears, but the efficiency is low and it is impossible to realize the free modification of the tooth surface; The requirements are high, and internal bevel gears cannot be processed; the milling-grinding process of disc cutters can realize tooth surface modification, but the processing efficiency is low

[0005] Gear skiving is an efficient and high-precision manufacturing process for cylindrical gears and ring gears. The gear skiving process can only be applied to cylindrical gear parts (including internal and external gears, splines, couplings, etc.). Other processing theories and product objects limit the promotion of this technology to a certain extent.
