The lifespan of the bearing is divided into fatigue life, service life; wear life; fault life. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
1. Weary life: the raw material of the primary moving parts of the bearing reaches the limit; the cumulative time before the bearing fails.
Additional dynamic load: the life is 10,000 rpm; the bearing can accept the load.
Equivalent dynamic load: refers to the assumed load of the bearing's practical load converted according to the working conditions of the dynamic load.
2. Lifespan: It is the general reference of the above three kinds of lifespan; in theory, it refers to the fatigue life of the bearing; in normal operating conditions, it shows the bearing wear life; when the conditions are not normal; when there are no shortcomings in the production; The number of illnesses.
3. Wear life: the bearing is due to normal wear; the accumulated working time before the rule is increased to the limit of the rule. At today's bearing industry level; the wear life should be > fatigue life; but in practice the traction motor is the opposite.
4. The number of illnesses: the problem of bearing attack; it is the accumulated working time before the loss of working ability.
Then the bearing is smooth and what is the relationship between the bearing life; look at the bearing's smooth intention we know:
The intention of the bearing is smooth:
1. Extended fatigue life.
Bearing rolling fatigue life; in rotation; rolling touch surface is smooth and outstanding; then extension. This is the biggest advantage of smooth bearings; can add fatigue life; extend bearing life.
2. Cut conflicts and wear out.
The ferrules, the tumbler and the holder that make up the bearing touch each other; avoid metal touch; reduce conflict and wear.
3. Discharge conflict heat, cooling cycle oil method, etc. can use oil to discharge heat from conflicts; or heat from outside; cooling. Avoid bearing overheating; avoid aging oil itself.
4. Other partner smooth bearings also have the ability to invade the inside of the bearing; or to avoid the rust and corrosion of the bearing.
