The key factors of precision casting
gears are analyzed as follows: in the process of gear processing, those advanced blank forming processes, more stable and precise heat treatment procedures, and particularly suitable surface hardening treatment procedures, these are the final steps to form gears The key element of quality. For example, there are several key links in the grinding process: only by selecting a grinding wheel with a sharp grinding edge and a small grinding surface stress, the grinding feed can be increased, thereby shortening the grinding time. It is to improve the grinding efficiency and prolong the dressing interval of the grinding wheel to reduce the cost.
Design is the key step and the initial step of precision casting. For gear casting, design is also its key step. It is related to the quality and level of the cast gear. In the design stage, select the appropriate cast gear material, carry out Advanced and reasonable structural design, selection of efficient and reliable gears and bearings are indispensable links.
On the premise of ensuring no grinding burn cracks and ensuring quality, it is necessary to use higher grinding parameters as much as possible to shorten the grinding time, so as to improve the grinding efficiency and increase the output, but also to ensure its accuracy, Reduce surface roughness. By using a more suitable grinding oil, it can ensure good lubrication and rust prevention, which is more conducive to reducing the surface stress of the grinding tooth surface, avoiding burn cracks, reducing roughness, and reducing the degree of blocking the grinding wheel pores. , to ensure the sharpness of the grinding wheel, thus reducing the dressing of the grinding wheel, reducing the amount of grinding wheel and reducing the cost.
