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 ...
