How to improve the bearing capacity of rv reducer

　　With the development of planetary transmission technology, the application of rv reducer has become more and more extensive. It has the characteristics of compact structure, high transmission efficiency, and large transmission ratio. Therefore, it has been widely praised. In the use of this equipment, there are often many The work is concentrated in this link of gear transmission, and in order to improve the operating efficiency, the first thing we should do is to increase the bearing capacity of the reducer.
　　1. The choice of gear material
　　For heavy-duty gears, the surface is required to reach a certain degree of hardness, to ensure the contact strength, metal wear resistance, and the core to have a certain degree of toughness.To meet these requirements, the gears need to be carburized and quenched.The material is generally alloy steel with a carbon content of less than 0.2%, and the alloying elements are generally Cr, Ni, Mo, Ti, etc.These elements have significant effects on improving hardenability, refining grains, improving wear resistance and toughness, respectively.
　　2. Increase tooth width
　　When the outer diameter of the rv reducer is required to be unchanged, appropriately increasing the width of the internal gear can effectively increase the bearing capacity of the gear and increase the bearing torque of the reducer.At the same time, the unit load under constant torque can be reduced.At the same time, the deflection of the gear teeth can be reduced, the noise excitation can be reduced, and the transmission noise can be reduced.If the tooth width coefficient is too large, it may result in poor rigidity and large deformation of the pinion, causing eccentric load on the tooth width, and the contact accuracy cannot be guaranteed.Generally, the tooth width coefficient of cylindrical gear is 0.4~0.8.
　　3. Gear modification
　　When the gear pair is under heavy load, the gear teeth will produce larger bending deformation when meshing.Due to the shape, the base section of the driving wheel participating in the meshing tooth becomes shorter, and the base section of the corresponding tooth of the rv decelerating motor wheel becomes longer. Interference occurs when entering and exiting the mesh, and it occurs at the tooth top and the tooth root.
　　For heavy-duty gears, generally repairing at the tooth end can prevent the tooth end from overloading due to tooth orientation errors.Tooth shape trimming, root trimming and tooth end trimming are better ways to improve the gear transmission performance of heavy-duty gear reducers.The amount of tooth tip trimming is closely related to the load. Proper trimming can ensure the smoothness of the gear pair meshing (engaging in and out), reducing dynamic load and noise, and improving bending strength and contact strength.
　　4. Increase gear modulus and tooth profile angle
　　To keep the outer diameter size of rv reducer unchanged, it is necessary to increase the load-bearing capacity, which can be met by reasonably increasing the gear modulus and reducing the number of gear teeth.Large-modulus gears can improve the bending strength of gears, which is an important indicator of gear carrying capacity.At the same time, the meshing angle a'can be increased, which is beneficial to increase the comprehensive radius of curvature, reduce the Hertzian stress, and improve the bearing capacity.
　　Therefore, in order to improve the bearing capacity of the rv reducer, you can start with the selection of gear materials, increase the tooth width, gear modification, and increase the gear modulus and tooth profile angle, so that the equipment can operate more efficiently.
