Discuss in detail the key factors of precision casting gears

The key factors of precision casting gears are analyzed as follows:

In the gear processing process, advanced blank forming technology, more stable and more precise heat treatment process and particularly appropriate surface hardening treatment process are important factors for the final formation of gear quality. For example, there are some important links in the grinding process: only by choosing a grinding wheel with sharp grinding edges and low grinding surface stress can the grinding supply be increased, the grinding time is shortened, the grinding efficiency is improved, the interval between grinding wheel dressings is extended, and the cost is reduced. .

Design is the key step and initial step of precision casting. Design is also a key step of gear casting, which is related to the quality and level of cast gears. In the design stage, it is an indispensable link to select suitable casting gear materials, carry out advanced and reasonable structural design, and select efficient and reliable gears and bearings.
On the premise of ensuring grinding burn cracks and quality, higher grinding parameters should be used as much as possible to shorten the grinding time, so as to improve the grinding efficiency and output, and ensure its accuracy and surface roughness. By using a more suitable grinding oil, it can ensure that under the premise of good lubrication and rust prevention, it is more conducive to reducing the stress of the grinding tooth surface, avoiding burns and cracks, reducing the roughness, reducing the degree of clogging the pores of the grinding wheel, and ensuring the grinding wheel Sharp, reduce grinding wheel dressing, reduce the amount of grinding wheel, and reduce cost.
