Embodiment 1

[0025] like figure 1 figure 2 As shown, a moving ring detection bearing includes an outer ring 2, an inner ring 1 and several balls, the outer ring 2 is a static ring, the inner ring 1 is a moving ring, the inner ring 1 is connected to a rotating shaft 7, and the rotating shaft 7 is provided with a A sensor device for detecting the vibration and temperature of the inner ring 1.

[0026] The sensor device includes a housing 3 and a main control chip arranged in the housing 3, a plurality of temperature sensors, a vibration detection device, a wireless communication device, a wireless power supply receiving coil 5 and a power adjustment unit; the bearing is fixedly arranged in the bearing housing 6, A wireless power supply transmitting coil 4 is fixedly arranged in the casing 6, and the wireless power supply transmitting coil 4 cooperates with the wireless power supply receiving coil 5; the wireless power supply receiving coil 5 is connected with a power adjustment unit, and t...

Embodiment 2

[0041] A moving ring detection bearing, comprising an outer ring 2, an inner ring 1 and several balls, the outer ring 2 is a static ring, the outer ring 2 is a moving ring, and the outer ring 2 is provided with a sensor device for detecting the vibration and temperature of the inner ring 1 . At this time, the outer ring 2 is a moving coil, which rotates with the rotating body, and the sensor device monitors the temperature and vibration of the outer ring 2 in real time.

Abstract

The invention relates to a moving race detection bearing, comprising an outer race, an inner race and a plurality of balls; the outer race is a fixed race; the inner race is a moving race; a rotary shaft is connected in the inner race; the rotary shaft is provided with a sensor device to detect vibration and temperature of the inner race. The moving race detection bearing has the advantages that traditional fixed race detection is modified into existing moving race detection, the temperature and vibration of the bearing can be detected more sensitively, and the response speed is higher; operating state of the bearing can be detected and monitored online in real time, and the operating state can be controlled in real time.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a moving ring detection bearing. Background technique [0002] In order to detect the working conditions of the bearings in real time, some bearings are now equipped with temperature or vibration sensors. The bearings include inner rings and outer rings. During operation, one rotates and the other is stationary, which are called moving rings and static rings. Smart bearings at this stage The sensors are all integrated on the stationary ring. In the past, the sensor is arranged on the stationary ring, which has the following defects, such as slow detection response and insensitive defects. [0003] Research by Purdue University in the United States shows that there is a significant difference in the temperature distribution inside and outside the bearing. The temperature of the moving ring is much higher than that of the static ring, and the temperature response of the moving rin...
