Embodiment 1

[0024] Embodiment 1: as figure 1 As shown, a main drive bearing test bench includes a bench 24, a power mechanism is integrated on the bench 24, and the power mechanism is used to provide axial force, radial force and overturning moment for the test bearing system. Test the bearing system, the test bearing system is connected with the power mechanism.

[0025] The test bearing system includes a test bearing 7, a test bearing connection flange 8, a test bearing load large flange 18 and a test bearing connection plate 3, and the test bearing connection flange 8 is connected to the test bearing outer ring and the test bearing load through high-strength bolts 9. The large flanges 18 are connected, the test bearing outer seal 6 is installed between the test bearing outer ring and the test bearing connection plate, the test bearing load large flange 18 is arranged on the outside of the bench 24, the test bearing load large flange 18 is connected with the power mechanism and The pow...

Embodiment 2

[0029] Embodiment 2: as figure 2 As shown, a main drive bearing test system includes a main drive bearing test bench, and the test bearing system and the power mechanism in the main drive bearing test bench 24 form a load test system, and the test bearing system and the driving mechanism are installed in the bench 24. system, the bearing system to be tested is connected to the drive system and the test bearing system and the bearing system to be tested rotate synchronously. The load test system, the bearing system to be tested and the drive system form the main drive bearing test system under simulated working conditions. Through two sets of bearing systems Synchronous operation, eliminating the friction of the rotating pair. By loading the test bearing system, the bearing force of the test bearing system is transmitted to the bearing system to be tested, thereby realizing the performance test of the bearing system to be tested, and simulating the real working conditions close...

Abstract

The invention provides a main drive bearing test bench and a test system. The test bench comprises a bench frame; a power mechanism is integrated on the bench frame, a test bearing system is installedin the bench frame, and the test bearing system is connected with the power mechanism. According to the invention, through synchronous operation of the two sets of bearing systems, elimination of friction revolute pairs, loading of the test bearing system and transmission of the bearing force of the test bearing system to the to-be-tested bearing system, the performance test of the to-be-tested bearing system is further realized, and the stress condition of the main drive bearing under the real working condition is simulated; therefore, the test result is greatly improved to be close to the real environment, the powerful data support is conveniently provided for subsequent product development, the overall structural design is compact, equipment is highly integrated, and the operation reliability is improved.

Description

technical field [0001] The invention relates to the technical field of the main drive bearing test of a shield machine, in particular to a main drive bearing test bench and a test system. Background technique [0002] At present, the large-scale main bearing test bench mainly carries out tests around the main bearing of wind power, and the main bearing test of the shield machine is still in the exploratory stage at home and abroad. In addition, in order to eliminate the bearing friction and rotating pair, the loading method of this type of test bench is directly loaded on the fixed ring of the bearing, without considering the actual loading of the bearing (some are loaded by the moving ring), which increases the uncertainty of the test results. For example, in the patent application number "2019111653004", the patent name is "A main bearing axial force loading test device" and the patent application number is "201710320452.1", the patent name is "Shield machine main bearing ...
