The main differences between worm wheel gear grinding machines and profile grinding wheel gear grinding machines are reflected in the processing principle, processing efficiency, application scope and structure of the machine -tool. The specific analysis is as follows:
1. Working principle
– The working principle of the worm gear grinding machine is similar to that of the gear hobbing machine. It uses a worm-shaped grinding wheel to continuously mesh with the gear to form the involute shape of the gear teeth.
– The shape grinding wheel gear grinder directly grinds the shape of the gear teeth by matching the grinding wheel with a specific tooth shape, which is similar to using a tool to directly cut the shape of the gear the gear.
2. Treatment effectiveness
– The worm gear grinding machine is suitable for mass production of small and medium module gears because it uses the generation method for grinding, which is most efficient in batch grinding of small module gears. and medium modules.
-The forming wheel gear grinding machine can process gears with large diameter, large module and small number of teeth. It is more suitable for flexible production and complex modification of tooth surface. Its production efficiency may be subject to some limitations, but its grinding contact. The area is larger than the expansion area. Thorough grinding can also achieve faster material removal and improve grinding efficiency.
3. Scope
-The forming wheel gear grinding machine is not limited by module size or number of teeth. It is suitable for high-precision gears which have modification requirements for tooth shape, drum shape requirements for tooth direction and special requirements. for the transition parts of tooth root and tooth top, and the accuracy can reach level 2 to level 3 and is stable to level 3.
-Although the worm wheel gear grinding machine can also achieve higher precision processing, its precision may not be as high as that of the formed wheel gear grinding machine, and the grinding wheel needs to be replaced when processing gears with different modules, which limits its applicability to a certain extent.
4. Machine tool structure
-The shape grinding wheel gear grinding machine has simple structure, stable and reliable performance, relatively cheap price and easy maintenance.
-The structure of the worm gear grinding machine is more complex and may require more maintenance and technical support.
In summary, for the mass production of standard gears with small and medium modules, a worm wheel gear grinding machine may be more suitable, while for gears with extra-large modules and a small number of teeth or special tooth shape processing, forming machine The grinding wheel gear grinding machine can be more suitable.
