Judgment can remove the bearing under the reuse (

, check after cleaning the outer spherical bearing, carefully check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, bearing clearance whether to increase, and presence of falling damage, abnormal size precision.
Thin wall bearings manufacturer of angular contact ball bearings can match the optimal number of balls and the contact Angle of 30 °.
They support radial load is higher than contact bearing deep groove ball bearings or four o 'clock, and can support comes from the same direction of axial load.
According to special requirements, the separation of small ball bearing etc. , the inner ring with one hand flat end, rotate the outer ring confirm whether smooth.
This type of bearings bearing separation, rolling body, the outer ring raceway surface can be patrolling, respectively.
Large bearing (
轴承)
Can't rotate with the hand, pay attention to (
注意)
Check the rolling element and raceway surface, cage and guard surface appearance, bearing the importance of the higher, the need to be careful to check.
Bearing bearing lubrication method, divided into grease lubrication and oil lubrication.
In order to make the bearing function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method.
If only consider lubrication and oil lubrication.
However, grease lubrication can simplify the structure of bearing the surrounding of the special features, compare the pros and cons of grease lubrication and oil lubrication.
Judge bearing can use again, according to the damage degree of bearing, mechanical properties (
兴能)
, importance, and operating conditions, the factors related to inspection cycle to decide.
But check if found any of the following defects, the bearing can't continue to use, need to replace the new outer spherical bearing.
1, viscosity lubrication condition between the rolling contact surface to form a enough to separate the two surfaces of the lubrication film, lubricant,
Effect: can reduce or avoid friction and wear)
At normal operating temperature must keep certain minimum viscosity in order to reduce the bearing friction, high bearing life (
一生)
Ring, the main factors of work for bearing average diameter and speed.
Work viscosity lubricant in the working temperature of viscosity by working at t4 ℃ temperature and according to viscosity glue according to the temperature curve of viscosity ratio is a markers of oil film forming ability,
目标的目标)
By its rotation speed has a great influence on bearing life, running state variation (
The temperature rise, reduce speed (
减少)
, dye content increased)
Outside the spherical bearing life may be big pollution, lower amplitude.
2, the correction coefficient of bearing life calculation and influencing factors (
因素)
Analysis of the correction coefficient calculation method.
Analysis of all kinds of influence the correction coefficient for calculate a foundation coefficient of bearing life, make better lubrication conditions of the SKF bearing, should be greater than or equal to the viscosity (
粘度)
Than also cannot too much, otherwise the increase in viscosity could make the bearing work (
工作)
Temperature rise.
When extreme pressure additive lubricating oil should be adopted in addition the pressure between the moving surface can change the lubricating oil viscosity, the symbolic calculation method are taken into account the operating conditions (
Working temperature speed load reproduced size lubrication condition the influence of external spherical bearing life.
Bearing is set up and reform, insulating cover, cover a usually covered with paper or other containers, transportation has a wooden and bamboo paper or in a time step by step.
If there is a plastic sheet roll and tapered roller bearing cup.
Bearing lubrication to ensure good effect.
Inspect the lubrication oil pump in good condition, pipe (
Conduit)
Flow spark specifications tank, in order to ensure sufficient supply.
Lubricating oil is clean with no dirt, at the same time the cursor within the scope of the right time, and in the correct gear oil, about five minutes after the winter oil viscosity check, to check the oil level in the range you can run the oil slowly, said it is necessary to take the compensation level.
Use bearing specification, has been playing to the outer spherical bearing life come to an end.
Situation is relatively small, are generally in operation process for various reasons caused damage to bearing, serious directly producing bearing scrapped off and reason for the installation,
ān zhuāng)
, use, lubrication,
lubrication)
These three aspects, common have SKF bearing ring gear had caused by the injury, the main reason is the insufficient lubrication or foreign bodies.
Must first rule out the cause of the accident to solve these problems, combined with the environment, site, structure, and so on several aspects to inspect a similar accident happening again, bring unnecessary trouble.
