What are the ways to improve the bearing capacity of the reducer?

In order to improve the bearing capacity of the reducer, the internal and external meshing gear pairs must meet the requirements of strength life and meshing quality. The following bonfiglioli reducer introduces in detail the methods to improve the bearing capacity of the reducer. The selection of gear material for heavy-duty gears requires a certain surface hardness to ensure contact strength metal wear resistance and a certain toughness in the core. To meet these requirements, gears need Carburizing and quenching. The alloy steel with carbon content less than 0.2% is generally used, and the alloy element is Cr-NiNiMo-Ti and so on. These elements play a significant role in improving hardenability, grain refinement, wear resistance and toughness respectively. It can effectively increase the bearing capacity of gear and improve the bearing moment of reducer. At the same time, the unit load under constant torque can be reduced. At the same time, it can reduce the bending of gear teeth, reduce noise excitation, and play the role of reducing transmission noise. If the tooth width coefficient is too large, it may lead to poor rigidity and large deformation of pinion gear, which can cause bias load on tooth width and can not guarantee contact accuracy. In general, the gear width coefficient of cylindrical gear is 0.4 ~ 0.8. 3. When the gear pair is subjected to heavy load, the gear tooth meshing will produce large bending deformation. As a result of deformation, the base joints of the active gear participating in the meshing gear become shorter, the base joints of the corresponding teeth of the drive wheel become longer, the interference occurs when entering and exiting meshing, and occurs at the top and root of the tooth for the heavy-duty gear. Generally speaking, practicing at the end of the tooth can prevent the overloading of the tooth end caused by the error of the tooth direction. Tooth profile modification, root modification and tooth end modification are better ways to improve the transmission performance of heavy duty gear reducer. There is a close relationship between the size of the tooth top repair edge and the load. The proper repair edge can ensure the smoothness of gear pair meshing (gnawing in and out), reduce the dynamic load and noise, increase the bending strength and contact strength, and increase the gear modulus. In order to maintain the same dimension of gear reducer with increasing gear profile angle, it is necessary to increase the bearing capacity, which can be satisfied by reasonably increasing the gear module and reducing the gear tooth number. Large modulus gear can improve the bending strength of gears, and bending strength is an important index of gear bearing capacity. At the same time, the meshing angle can also be increased, and the increase of the meshing angle is beneficial to increase the radius of comprehensive curvature and reduce the Hertz stress. These are the methods of improving the bearing capacity of the reducer introduced by the bonfiglioli reducer. I hope the summary of the small editor will be helpful to everyone.
