Improve the bearing capacity of precision planetary reducer，There are several ways to start。Here are some of the main methods and strategies：

one、Gear design and optimization

1. Gear modification：

• Tooth shape trimming、Root repair and tooth end repair are effective methods to improve the performance of heavy gear transmission。These modification measures can prevent overload caused by tooth orientation errors，Thereby increasing the carrying capacity。

• Pay special attention to the size of the tooth top trim，It is closely related to the size of the load，Proper trimming can ensure the smoothness of gear pair meshing，Reduce dynamic load and noise，Improve flexural strength and contact strength。

2. Increase the gear module and tooth Angle：

• In the case that the outside diameter of the equipment is unchanged，The load capacity can be improved by reasonably increasing the gear module or tooth Angle。Large modulus gear can improve the bending strength of gear，The adjustment of tooth shape Angle is also beneficial to increase the comprehensive curvature radius，Hertzian stress reduction。

3. Increase tooth width：

• In the case of the transmission outside diameter requirements unchanged，Appropriately increasing the width of the internal gear can effectively increase the bearing capacity of the gear。This can not only improve the bearing torque of the reducer，It can also reduce the unit load at constant torque，Reduce tooth deflection and transmission noise。

4. Adjust the coefficient of displacement：

• Correct selection of displacement coefficient can improve the bearing capacity of gear20%to30%。The adjustment of displacement coefficient can improve the meshing quality、Increase bending strength，And helps to fit in the center distance，Thus improve the service life of the gear。

two、Material and process

1. Choose high quality materials：

• Gear with good material，Its carrying capacity is stronger than the general material，It also has better wear resistance。For heavy gear，Materials are generally used with less carbon content0.2%Alloy steel，If joinedCr、Ni、Mo、TiIsoalloying element，To improve hardenability、Refined grain、Improve wear resistance and toughness。

2. Root reinforcement treatment：

• The fatigue strength of tooth root bending is reduced，The measures of tooth root strengthening can be taken to improve the fatigue strength。Such as，There may be defects such as decarburization layer on the surface of tooth root of carburized quenched gear，The defective layer is removed by shot peening，Can ensure the bending strength of the tooth root。

three、Lubrication and maintenance

1. Choose suitable lubricating grease：

• Improper use of lubricating oil is one of the main reasons for gear failure。Should choose suitable、Reasonable lubrication method and lubricating grease，To improve the service life of the equipment。The choice of lubricating grease should be based on the load、speed、Transfer power、Meshing efficiency、Bearing efficiency and inlet and outlet temperature difference and other factors。

• Suitable lubrication methods include grease lubrication、Splash lubrication（Oil bath lubrication）And forced lubrication（Oil injection lubrication of circulating oil station），The selection should be based on the circular speed and speed of the gear。

2. Control tooth surface roughness：

• Reducing tooth surface roughness is beneficial to lubrication，Easy to form a full oil film，Thus improve the lubrication performance。

four、Other notes

• Regular inspection and maintenance：Check the operating status of the planetary reducer regularly，Identify and address potential problems in a timely manner，Ensure the normal operation of the equipment。

• Reasonable design and selection：In the design and selection，The conditions of use of the equipment should be fully considered、Load characteristics and performance requirements，Select the appropriate planetary reducer model number and specifications。

To sum up，It is necessary to consider the gear design comprehensively to improve the bearing capacity of precision planetary reducer、Material selection、Lubrication and maintenance and other aspects。By taking the above measures，It can effectively improve the bearing capacity and service life of the planetary reducer。
