I. General

Bearing is one of the indispensable parts in various mechanical equipment, in order to ensure the quality and performance of bearings, need to carry out a number of experiments. Common bearing performance experiments include load bearing experiments, friction coefficient experiments, fatigue life experiments and so on. These experiments can not only provide reference for bearing manufacturers, but also provide important reference data for bearing users.

Second, load bearing test

Load bearing performance is one of the basic performance of the bearing, the test method is to install the bearing in the load bearing device on the test, determine the bearing to withstand large loads. This experiment can directly reflect the bearing in the work can withstand the size of the load, but also agreed on the basis of bearing performance indicators.

Third, the friction coefficient test

The coefficient of friction of the bearing determines the friction heat and power loss produced by the bearing in the work and other indicators. Friction coefficient test is through the measurement of bearing rolling friction and bearing internal friction and the sum of the calculation. The friction coefficient experiment of bearings can provide important reference data for the use of bearings, and help to deeply understand the principle of friction and reduce power loss. Fourth, fatigue life test

Bearing fatigue life test is an important means of evaluating the working life of bearings, the purpose of the experiment is to determine the life of the bearing under the specified conditions and the cause of failure. In the fatigue life experiment, usually through repeated loading and repeated impulse loading to reproduce the actual working conditions of the bearing in the work. This kind of experiment can simulate the changes in the working environment of the bearing and reflect the life of the bearing more realistically.

V. Other experiments

In addition to the above three common bearing performance experiments, there are some other experiments are also very important, such as bearing noise experiments, axial clearance experiments. These experiments can provide bearing manufacturers and users with more comprehensive bearing performance evaluation data, and can guide the use and improvement of bearings.

Sixth, the conclusion

Bearing performance experiments are very important to ensure the quality and performance of bearings. Through the determination of load bearing, coefficient of friction, fatigue life and other experiments, the performance indexes of bearings can be effectively evaluated. These experiments not only provide reference for bearing manufacturers, but also provide users with important reference data for using bearings.
