[0002] Gearbox performance testing is a process of evaluating gearbox performance through a series of tests. These tests include, but are not limited to, gearbox noise testing, gearbox vibration testing, gearbox temperature testing, and gearbox fluid testing. Gearbox performance testing is a quality assurance measure for gearboxes, ensuring their stability, durability, and reliability during use. However, the performance testing of axle gearboxes generates significant noise, making it impossible to conduct the tests in a soundproof environment, which would cause noise pollution and reduce the environmental friendliness of the testing equipment. Furthermore, the inability to perform fixed tests on axle gearboxes directly reduces the accuracy of the test data. Therefore, we have redesigned a performance testing system for high-speed train axle gearboxes. Utility Model Content
