TIMKEN imported bearings will inevitably be damaged during the working process; such as the appearance of abnormal heating, oscillation and noise increase; indicating that TIMKEN bearings can be damaged now; the following engineers from Shanghai Axis Research and Trading Co., Ltd. explain the common TIMKEN bearings Several ways of damage.
The most common and most common is the TIMKEN imported bearings exhibit cracking and cracking; this condition is usually due to data defects and heat treatment; the cooperative interference is too large; the combination is not properly drawn; if the bearing surface is grooved, it will cause stress concentration; Will form a ring crack and crack.
Secondly, TIMKEN imported bearings show the damage of the cage. This situation is mostly on the high-speed TIMKEN bearing; because the high-speed TIMKEN bearing smoothing agent is lacking; the wearer and the body or the ferrule touch point wear, bump, and even cause the cage to crack.
The most common damage is the TIMKEN bearing work; the wear and rust are unpredictable; these two types of damage are usually prevented by punctual inspection and protection; for example, when the TIMKEN bearing seal is not good; the dust or particulate matter is allowed to enter. TIMKEN bearings; or poor smoothness; will cause severe scratches or abrasions on the touch surface; and increase the oscillation and noise of TIMKEN bearings. Intrusion of moisture or acid, alkali, salt and other materials into TIMKEN bearings or smoothing agents is not appropriate. Will be cited as TIMKEN bearing corrosion.
There is also a kind of fatigue that is also a simple damage of TIMKEN bearings; mainly in the raceway or external surface of TIMKEN bearings; because of the effect of accepting alternating load, the surface of the touch surface is flaky; and gradually expands to form a concave Pit. If it continues to work, it will constitute the area shedding area. Because the device is not suitable or the TIMKEN bearing seat hole and the centerline of the shaft are skewed, the TIMKEN bearing will receive a large load and cause early fatigue damage.
