Common Problems and Solutions of Planetary Reducer
1. the worn planetary gear tooth and gluing, pitting, grinding deviation and introduction (especially the pinion speed is very easy to wear) may cause vibration of the reducer.
Treatment: timely replacement of severely worn gears. Generally can use the reverse running method to solve the tooth surface serious gluing.
2.the planetary reducer gears of the meshing surface contact and uneven force, so that the axial movement of the gear frequently, the occurrence of tooth fracture or tooth ring fracture, as well as spoke cracks, etc., causing vibration of the reducer.
Treatment: replace the damaged parts; adjust the gear ring and spoke door with; replace the gear of tooth wear over limit; adjust the bearing clearance; improve gear lubrication, etc.
3. planetary reducer high-speed shaft and medium-speed shaft slide key wear introduced, shaft pinion coupling bolts have loosened or fracture caused by reducer vibration.
Treatment: replace the sliding keys and broken bolts, tighten the loose bolts.
4. planetary reducer gear rough machining and shaft and bearing wear, in normal operation, the tooth ring non-working surface stress, causing vibration of the reducer.
Treatment: replace the parts that meet the processing accuracy and roughness requirements; remove the worn shaft and bearings.
5. planetary gears and shaft with a large amount of interference, so that the shaft breaks at the fit caused by the vibration of the reducer.
Treatment: replace the broken shaft, adjust the gear and shaft with the amount of interference.
6. planetary gear and shaft shaft hole fit tolerance such as hole is too large, resulting in gears and shafts are not concentric, or gears and shafts are not properly assembled to produce loose phenomenon, causing vibration of the reducer.
Treatment: adjust the gear and shaft shaft hole fit tolerance; careful assembly to prevent loosening.
7. planetary reducer output shaft gear wheel center and ring loosening, side pressure plate activities or pressure plate bolts have loose or broken, as well as the large gear static balance or unbalance, causing vibration of the reducer.
Treatment: tighten the wheel center and tooth ring; tighten the pressure plate bolts, replace the broken bolts; improve the balance of the large gear.
