The common damage forms of XLD22-71-2.2KW cycloid pin wheel reducer output shaft are as follows:
Wear
Bearing position wear : The parts where the output shaft and the bearing are fitted will wear due to long-term operation, poor lubrication, improper matching clearance, etc., resulting in a decrease in the matching accuracy, affecting the performance of the reducer, causing problems such as jumping and vibration during operation of the output shaft.
Keyway wear : Keyway is used to connect the output shaft to external loads, such as couplings, gears, etc. During the torque transmission process, the friction and impact between the keyways will gradually wear out, and the keyway width will increase, resulting in loose fit between the keyways and the keyways and inability to effectively transmit torque.
Deformation
Bending deformation : When the radial force that the output shaft of the reducer is subjected to is too large, such as the concentricity deviation between the output shaft and the load during installation, and the load has a large eccentricity, etc., the output shaft will be bending deformation. The output shaft after bending and deformation will aggravate the wear of the bearing, and even lead to poor gear meshing, resulting in abnormal noise and vibration.
Torsion deformation : If the load carried by the reducer suddenly increases, or is frequently started and braked, the output shaft may withstand a large torque impact. When the torque exceeds the material's ability to withstand, torsion deformation will occur, which may cause the output shaft torsion.
fracture
Fatigue fracture : Under the action of long-term alternating load, microscopic cracks will occur inside the output shaft. As time goes by, the cracks will gradually expand. When it reaches a certain level, fatigue fracture will occur in the output shaft. Fatigue fracture usually occurs in areas where stress is concentrated, such as shoulders, keyways, transitional rounded corners, etc.
Overload fracture : Overload fracture occurs when the load bearing the reducer output shaft exceeds its ultimate load bearing capacity. For example, unexpected impact loads, wrong Selection may cause the reducer to operate under overload conditions for a long time, etc., which may cause overload and fracture.
Corrosion : If the reducer works in a humid, corrosive gas or liquid environment, corrosion may occur on the surface of the output shaft, reducing the strength and wear resistance of the shaft and accelerating its damage. In addition, acidic substances, moisture, etc. in the lubricating oil may also cause corrosion to the output shaft.
