Gear grinding machining method and device

Abstract

The invention provides a gear grinding machining method and device. The method adopts an abrasive belt which is high in grinding efficiency, the abrasive belt is in high-speed motion along the tooth width direction of a gear to conduct grinding, and the abrasive belt is in generating motion relative to a gear blank to grind each tooth socket tooth surface sequentially and swings slightly relative to the generatrix of the tooth surface to achieve crowned tooth surface shape correction. The device for achieving the grinding machining method is provided and comprises a bed body, a lifting table, a gear blank rotation dividing head, a gear blank flat moving work table, a gear blank dip angle table, an abrasive belt feeding work table and an abrasive belt deflection rotary disc. A numerical control system controls all the portions to be in linkage and conducts complementation of abrasive belt abrasion loss, machining of various gears can be achieved by using suitable press grinding plates and belt guiding wheels or guiders, disc-shaped or worm-shaped grinding wheels are not required, and the method and device has high machining efficiency and machining quality.

Description

technical field [0001] The invention relates to a gear processing method and equipment, in particular to a gear grinding processing method and equipment. Background technique [0002] Gear processing includes forming milling cutter milling, hob hobbing, worm grinding wheel grinding and other processing methods. Single-piece production can also use EDM to cut spur gears; among them, the process route of shaving or grinding after hobbing is The most typical industrialized mass production method. However, shaving is only suitable for soft tooth surfaces, and cannot process hard tooth surfaces after heat treatment, and the manufacturing precision of shaving cutters is high and expensive. Grinding generally uses a disc grinding wheel or a worm grinding wheel to perform generating motion with the gear blank to grind the tooth surface, and is generally used for finishing after shaving or heat treatment. Regardless of whether the disc grinding wheel or the worm grinding wheel is u...

Problems solved by technology

[0004] The invention provides a gear grinding processing method and equipment, which changes the point contact of the existing grinding wheel grinding, makes the abrasive belt contact the generatrix of the gear tooth surface, and makes a generating movement between the abrasive belt and the tooth blank, or the abrasive belt Under the action of the grinding plate, it is in full contact with the tooth surface, and the shape of the grinding plate is used to copy the profile of the tooth surface of the gear, which solves the shortcomings of the traditional gear grinding machine, such as frequent dressing of the grinding wheel and low processing efficiency.
