Test of gear bending fatigue limit based on up and down method The bending fatigue strength of gear is an important indicator for gear performance, it is a good approach to gain the bending strength in the light of the test procedure. The test of the single – tooth bending fatigue strength of 20CrMoH carburized gear is discussed. After a series of experiments, the result represents that it is more actual to determine the risk position with broken – line section method. It provides a new approach for evaluating the gear bending fatigue strength. Making full use of this theory, the gearbox can be improved in a certain level. With more than 20-year experience on gearbox and micro motor, Zhaowei has designed and produced tons of high-quality products.

Heat treatment method of planetary reducer

-
Choosing good material of planetary reducer is conducive to improving the bearing capacity and service life of gear reducer. In view of the structural characteristics of precision reducer and the load characteristics of gears, hard tooth face gears should be widely used. There are many heat treatment methods to obtain hard face gear. For example, surface quenching, whole quenching, carburizing quenching and nitriding should be selected according to the characteristics of gear reducer. 1. Surface hardening The common surface quenching methods are high frequency quenching (for small size gears) and flame quenching (for large size gears). When the hardened layer of surface hardening includes the bottom of the tooth root, the effect is the best. The hardness of tooth surface can reach 45-55HRC. 2. Nitriding The application of nitriding can ensure that the gear can achieve high hardness and wear resistance under the condition of minimum deformation. After heat treatment, ...

How to solve the wear fault of gear reducer

-
Gear reducers are generally used in low-speed, high-torque transmission equipment, but in fact gear reducers are often used in high-speed mechanical environments, so it is inevitable to withstand multiple types of friction. If not protected, wear failures are likely to occur. Such problems often occur, so we should learn to deal with these wear and tear. There are three kinds of wear faults of the gear reducer. One is the wear of the bearing chamber of the gear reducer, which includes the wear of the bearing housing, the bearing housing of the housing, and the bearing housing of the transmission. The second is the shaft diameter of the gear reducer gear shaft wear, the main wear parts are in the shaft head, keyway and so on. The third is the bearing wear of the gear reducer drive shaft. For the wear failure of the gear reducer, the traditional solution is repairing after repair welding or brush plating, but both have certain drawbacks. Generally, the thermal stress generated by th...
