Rotor electric motor
Applied in: Oil, Gas & Energy | Mechanical Engineering
Problem, idea and solution
The stub axle of the (electric motor) rotor has been severely damaged.
The roller bearing has jammed, which causes the inner ring of the bearing to rotate on the axle. As a result of the overload, the stub axle has bent by 0.2 mm.
Bearing ring is removed, the axle is adressed and then repaired by flame spraying and grinding.
Because flame spraying a relatively "cold" process, there is no risk of the axle warping or the rotor overheating.
Fretting is a type of wear that occurs as a result of undesired tiny movements between two components. Consequently, wear...
Every type of wear requires dimensional recovery. Dimensional recovery is also required when a design or machining error...
