Description

technical field [0001] The invention relates to the field of dynamic monitoring of the health status of key parts of mechanical equipment, in particular to an installation assembly suitable for monitoring rotating parts of rolling bearings, which is an improvement of on-line monitoring systems and common parts, especially for bearing positioning spacers and lock nuts Such as the transformation of bearing installation components, so that it can monitor the temperature, speed, and vibration signals of the rotating parts of the bearing (including the inner and outer rings of the bearing, and the cage) online. Based on these real-time measurement signals, it cooperates with the proprietary bearing operating status evaluation and fault diagnosis. Algorithms to realize the perception of the running state of rolling bearings, so that ordinary bearings become intelligent bearings with the function of sensing working conditions. Background technique [0002] Rolling bearings are wide...

Problems solved by technology

The main reason is that the bearing is installed in the bearing seat, the space is narrow and the environment is complicated

The relatively mature electromagnetic coupling wireless power supply can realize wireless energy supply. Ding Chuang and Zhao Yongdong from the Department of Mechanical Engineering of the Armored Corps Engineering College have realized torque measurement through non-contact inductive power supply technology, but the general electromagnetic coupling power supply scheme is difficult to meet the narrow ferromagnetic space. The energy supply in the medium, and the open alternating electromagnetic field is often accompanied by the eddy current effect, which will bring unnecessary heat sources, and then affect the test results of the bearing and even the entire shafting

Photoelectric conversion energy supply is a scheme without eddy current effect. It drives the energy receiving end through strong light irradiation, and then converts light energy into electrical energy to meet the energy demand of the system. However, for the working environment of the bearing, this energy supply scheme is difficult. Coping, the environment with oil and oil mist can easily block the transmission of light, and the deposition of oil on the energy receiving end is inevitable
