The damage state of spherical roller bearing, such as: card injury roller bearing rings of ribs, may consider as reasons, lack of lubricant, not suitable for bending, for defects, foreign oil discharge structure of invasion, TIMKEN bearing installation error, shaft is too large, also for these reasons coincide.
1, cavitation
Cavitation self-aligning roller bearing is surface damage form of contact with the liquid and solid surface arising from their relative motion. When the lubricating oil in the oil film oil low pressure area, will form a bubble, bubble motion to the high-pressure zone, under pressure of bubble collapse, great impact and high temperature in the collapse of the moment, repeated action of solid surface in the impact force, material fatigue loss, the friction surface of small pit, and then developed into a cavernous scars. Heavy load, high speed, and the load and speed changes in the larger TIMKEN bearing, often cavitation;
2, the fluid erosion
Fluid erosion self-aligning roller bearing is the fluid fierce impact of solid surface can cause fluid erosion, make the point. The solid surface, the surface of this injury is smooth;
3, the electrical erosion
The electric erosion of spherical roller bearing is due to motor or electric leakage, in the TIMKEN bearing friction spark surface, causing punctate scars in the friction surface, which is characterized in injury reciprocating appeared in stiffer shaft neck surface.
