Product Description
Customized Copper Bushing for Swing Gear of Steam Turbine Turning Gear
Copper Bushing for Swing Gear of Steam Turbine Turning Gear. In the transmission mechanism of the steam turbine turning gear, the swing gear serves as a key movable transmission component. Its smooth operation and stable meshing rely on a well-designed supporting structure.
Installation Position and Structural Features
The rotation center of the swing gear is on the driving gear shaft, and its journal is fitted with the copper bushing. Generally tubular in structure, the copper bushing has a precisely machined inner wall with high surface finish. It is sleeved on the shaft end of the swing gear and fixed to the housing of the turning gear or the rocker arm support structure. It provides stable support for both the revolution of the swing gear (rotating around the pinion on the driving shaft) and its rotation (spinning on its own axis during torque transmission).
Core Functions
Friction Reduction and Lubrication
Copper bushing material features excellent wear resistance and self-lubricating performance. It reduces friction resistance of the swing gear journal during rotation and lowers wear, preventing jamming or damage caused by direct metal-to-metal contact.
Positioning and Guiding
The fit clearance between the copper bushing and the journal is precisely designed to guarantee accurate axial positioning of the swing gear, ensuring proper tooth backlash and avoiding tooth surface impact or poor meshing.
Vibration Damping
During engagement or disengagement from the turning gear, the copper bushing absorbs part of the impact force through minor self-deformation, reducing vibration of the transmission mechanism and protecting gears and shaft components.
Correlation with Turning Gear Operation
  • When the turning gear engages automatically, the swing gear revolves clockwise driven by the pneumatic actuator. The copper bushing ensures a stable motion trajectory for smooth meshing.
  • During steam turbine startup, the swing gear revolves counterclockwise and disengages from meshing. The low-friction property of the copper bushing enables smooth disengagement and prevents failure due to jamming.
  • If the copper bushing is worn or fit clearance becomes excessive, the swing gear may deflect, causing abnormal noise, accelerated wear, and potential impact on automatic interlock function.
Maintenance Points
  • Regularly inspect the wear condition and lubrication status of the copper bushing
  • Ensure no scratches, peeling or overheating marks on the inner wall
  • Keep mating surfaces clean to avoid abrasive wear from impurities
  • Strictly control fit clearance during replacement to comply with equipment technical specifications
Although the swing gear copper bushing is a small component in the turning gear, its performance directly affects the reliability of the transmission mechanism and the quality of gear meshing. It is an important support for the turning gear to realize core functions such as uniform cooling of the rotor and prevention of bending deformation.
