Common problems with the main propulsion system and auxiliary gear box of the ship - gear box reduction motor
The application fields of deceleration motors are becoming increasingly diverse, and abnormal situations may occur in daily life. Let's take a look at the abnormalities that occur in daily life.
1) Common problems with gearbox motors, marine diesel generator sets, and marine propellers:
1. The gearbox motor cannot be started during initial use
2. There is a collision sound inside the gearbox motor
3. Large engineering ship propeller, 56M engineering ship propeller output shaft does not rotate
4. The gearbox motor is experiencing oil leakage
5. The gearbox motor has a broken shaft phenomenon
2) Reasons and solutions for the problem:
1. ① Marine oil pump gearbox. Due to low temperature or other reasons, the flow of lubricating oil inside the reducer of the marine water pump gearbox deteriorates, and the instantaneous current of the motor increases, resulting in overload protection of the driver. It can be started a few more times.
② There is gear wear and iron cutting inside the gearbox motor, and it is necessary to disassemble and clean or replace the internal gears.
2. Full rotation thruster - the internal planetary carrier is displaced, and the friction between the internal gears causes iron cutting. At this time, it is necessary to replace the gearbox.
3. Gearbox for loader - If the output end bearing of the rudder bearing on the plane friction is displaced, deformed or worn, it is necessary to replace the machine and bearings, and check whether the internal gears are worn or cracked.
4. Harmonic reducer, mixer truck reducer - The condition of the crawler harvester walking gearbox is a common situation, mostly caused by excessive lubricating oil. When the excess oil is consumed, this situation will not occur.
5. ① If the decelerator operates for a long time under overload, the output shaft may partially break due to fatigue. Operating according to the manufacturer's specified requirements can greatly reduce the occurrence of such accidents.
② The output shaft of the maintenance machinery gearbox is subjected to uneven force, with radial loads exceeding the rated range, or working at the rated high force for a long time.
Planetary gearbox - At this point, it is necessary to check whether the load exceeds the rated range. If so, a larger model gearbox motor needs to be replaced.
