Abstract

The invention relates to a vibration and abrasion test bench. A vibrating shaft input end is connected with an electromagnetic speed adjusting motor; the vibrating shaft is fixed at the bottom of a box body by a bearing; the center of the vibrating shaft is connected with an eccentric wheel; the eccentric wheel is matched and connected with a push rod by a pressure spring; the push rod is connected with the box body in a sliding way; the push rod is connected with a rotary disc by screw thread; a load spring is connected between the rotary disc and a sample plate; the sample plate is arranged at the top of the push rod; a top end is fixedly connected with a guide bench; the sample plate is connected with the guide bench in a sliding way; a cover plate is fixedly connected on the guide bench; a clamp is connected on the cover plate in a moveable way; the lower end of the clamp is fixedly connected with a standard sample; the top of the box body is connected with a rotary shaft; the lower end of the rotary shaft is connected with the clamp in a sliding way; and the input end of the rotary shaft is connected with the motor. The test bench disclosed by the invention can provide various compound environments with variable load, the presence of vibration, the absence of vibration and the like for studies of friction and abrasion between solids under the vibrating condition and various precise instruments can be arranged on the test bench for scientific researches. The test bench has good organization expandability.

Description

technical field [0001] The invention relates to a vibration and wear test bench, in particular to a test bench for studying the influence of two factors of vibration and sliding friction and wear. Background technique [0002] At present, the single vibration and single wear test benches in the market can no longer meet the needs of development, and more and more people pay more and more attention to the test benches that study and measure vibration and wear at the same time. One of the existing vibration and wear test benches uses a force-measuring shedding mechanism and an experimental chuck to connect the vibrator to the entire testing machine, and conduct experiments and comparative tests on different friction and wear of materials such as static load and vibration on the testing machine. However, this kind of test bench adopts a gear transmission mechanism, which is bloated, and the vibration generated by the gear transmission mechanism affects the test accuracy; the ot...
