XC870K excavator loader Boom connection plate
The internal gear ring is the core component of the planetary gear transmission system. Its annular internal gear structure is coaxial with the planetary carrier, with a smooth outer surface and an involute tooth profile on the inner ring. As a fundamental component of the planetary gear system, the internal ring gear achieves power transmission, speed regulation, and direction change through internal meshing with the planetary gears, and plays a key transmission role in wind power equipment and engine starting systems. Its structural design needs to meet the constraint of concentric conditions, ensure equal distance from the center of the sun gear, and improve surface hardness and wear resistance through infiltration heat treatment
In terms of dynamic characteristics, the meshing stiffness and damping parameters of the inner ring gear and planetary gear directly affect the load balancing effect of the transmission system. In engineering applications, it is necessary to combine axial limit and tooth thickness optimization to ensure mechanical stability
