Multi-fault coupling gear box simulated experiment bench

Abstract

The present invention discloses a multiple fault coupling wheel case analog experimental table in the field of rotating machinery vibration monitoring and diagnosing, a plurality of typical faults of the gear equipment can be comprehensively, objectively and conveniently simulated, such as eccentricity, pitting, stripping, uniform abrasion on the tooth surface, tooth root fatigue crack, tooth breaking and the like; through dialing the assemble arrangement result of the gear with the fork spreader converting mechanism, the coupling fault signal and the signal varying process of the gear from normalization to fault generation can be continuously observed in operation. Besides, by arranging fault on the bearing the bearing fault and a bearing coupling fault of the gear can be simulated. The researching proofing procedure for the fault diagnosing method by the scientific researcher is greatly facilitated, the time from theory to the practice is shortened and the time and energy spent for arranging the experiment by the scientific researcher are saved. Besides, the multiple fault coupling wheel case analog experimental table can also be applied in the teaching practice for improving the learning and recognizing level.

Description

technical field [0001] The invention belongs to the field of vibration monitoring and diagnosis of rotating machinery, and relates to a multi-fault coupling gearbox simulation test bench for comprehensively, objectively and conveniently simulating several typical faults of gear equipment. Background technique [0002] Gear devices are widely used in various sectors of the national economy. The operating status of the gear device directly affects the equipment, personal safety and production benefits of the enterprise. Use scientific methods to monitor and judge the operation status of gear units, so as to understand the operation quality and prevent failures, which is of great value to the equipment management and economic benefits of the enterprise. As an important part of the theory and practice of mechanical fault diagnosis, gear fault diagnosis has attracted people's attention from the very beginning. Through years of basic theoretical research ...

Problems solved by technology

If there is only theoretical research but no experimental research, then the research on the effectiveness, accuracy, advantages and disadvantages of various gear fault diagnosis methods cannot be based on a solid scientific basis.

At present, most of the gear box test benches used by scientific research institutes are mechanical power closed type or electric power closed type running gear test benches, which are mainly used to observe the occurrence and development process of a single (or single pair) gear failure, such as imitating the German FZG's CL-100 gear testing machine is characterized by low cost, easy installation, and easy observation and measurement. However, it is necessary to replace the gear test piece to observe different faults, and one test can only observe one fault at the same time. It is inconvenient to study the gear fault diagnosis method
