Common problems with gearboxes
Thread Content
Common problems in gearboxes: Gear wear: Scratches, welding, pitting, corrosion that leads to cracks, and even breakage of the gear roots. Bearing failure: Alternating stresses cause pitting, corrosion, cracks, flaking, and ultimately bearing failure, which can cause significant damage to the gearbox. Excessive sludge and deposits inside the gearbox, as well as carbon buildup on the gear surfaces, lead to wear and corrosion, thereby shortening the lifespan of the gear oil. Vibrations, shocks, and high noise levels also reduce the lifespan of the internal components of the gearbox. Shaft breakage. High oil temperature
There is also shaft bending and twisting； Bearing \"running inside the circle\" and similar issues ；
Attention should also be paid to the oil lubrication and oil temperature in the gearbox; oil lubrication helps to reduce wear between the gears. When designing the gearbox, it is necessary to consider whether there is sufficient heat dissipation from the surface of the gearbox – if not, the oil needs to be cooled using a cooler.
