Abstract

The intensified tester includes load maintainer, test head parts, lubricating mechanism, control system and drive gear. The test head parts include test head and seat of test head. The test head is connected to the drive gear, and load maintainer. The control system is connected to the drive gear, the load maintainer, and the lubricating mechanism. The drive gear supplies power needed for test. The load maintainer supplies load needed for test. The lubricating mechanism makes tested bearing lubricating and cooling down adequately under normal condition. The control system is in use for controlling electric operations, protecting and recording test parameters, monitoring operational aspect of test, analyzing test procedure, test result, and carrying control feedback properly. Features are: reasonable design, compact structure, capable of presetting, measuring, controlling and auto recording test parameters. The tester can make alarming and stopping operation, and printing out cause.

Description

Technical field: [0001] The invention relates to a rolling bearing life and reliability strengthening test machine, which is mainly suitable for the strengthening test and rapid evaluation of the rolling bearing life and reliability. Background technique: [0002] In the early 20th century, my country's bearing industry has been using the former Soviet Union's ZS bearing life testing machine for bearing life testing. With the development of science and technology and bearing manufacturing technology, the performance of this kind of testing machine has obviously lagged behind the needs of actual test development. inconvenient. The F&M 5”B rolling bearing fatigue life testing machine imported from the United States is not only expensive, but also uses a pneumatic high-voltage power source and a 60Hz electric frequency, which is not suitable for China’s national conditions. Invention content: [0003] The technical problem to be solved by the present invention is to overcom...
