The products of the valve profession are widely used, so that the valve accessories are also developing rapidly. As for the valve driving equipment manufacturers, the long-term use of the valve will cause a lot of wear on the valve bevel gear and reduce its service life.

So how can we reduce the wear of bevel gear and improve the service life? In the view of Ba bevel gear manufacturers, there are actually the following methods. First of all, the selection of raw materials is necessary to be reasonable, and first of all, we must pass the quenching and tempering treatment. According to the change rules of two wheel sliding coefficient during gear transmission, the sliding coefficient of cast steel bevel gear tooth root is greater than that of its tooth top, and the sliding coefficient of pinion tooth root is greater than that of large gear tooth root. In order to make the tooth root wear of large and small reduction gears nearly equal, the pinion should be made of harder materials, In the heat treatment, its hardness is tens of HB higher than that of the big gear. The small gear can also be heated along the tooth groove by high-frequency induction and surface quenching to increase its wear resistance. For the initial work after replacing a new gear, generally only pay attention to whether the work and sound of each part are normal. If it is basically normal, it will be put into use. The running in and no-load test are insufficient, which can not achieve the intention of gear running in.
