The products of the valve profession are widely used, so that valve accessories are also developing rapidly.Regarding valve drive equipment manufacturers, the long-term use of valves will cause a lot of wear and tear on the valve bevel gearbox and reduce its service life.

So how can we reduce the wear and tear of bevel gears and improve the service life? In the eyes of BA bevel gear manufacturers, there are actually the following methods.To select raw materials, it is necessary to be reasonable, and must pass on the quenching and tempering treatment.According to the change rule of the sliding coefficient of the two wheels during gear transmission, the sliding coefficient of the tooth root of the cast steel bevel gear is greater than the sliding coefficient of the tooth tip, and the sliding coefficient of the pinion tooth root is greater than the sliding coefficient of the large gear tooth root, in order to make The tooth root wear of the large and small reduction gears is close to the level. The small gear should be made of harder materials, and the hardness of the small gear should be dozens of HB higher than the hardness of the large gear. The small gear can also be selected with high-frequency induction edge Groove heating and surface quenching increase its wear resistance.In the initial work after replacing the new gear, generally only pay attention to understanding whether the working and sound of each part is normal. If it is normal at all, it will be put into use. Running-in and no-load experiments are not sufficient, and the intent of the gear running-in is not achieved. Bevel gear box Bevel gear box
