Description

Technical Field

[0001] The utility model relates to the field of bearing detection, in particular to a bearing wear detection mechanism. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment that supports mechanical rotating bodies and reduces the friction coefficient during their movement. Due to the high dimensional accuracy requirements of their processing, the internal wear-resistant alloy coating is very thin, so it is very easy to wear after long-term use. Regular inspection operations are required to determine whether the bearing needs to be repaired or replaced, so as to prevent damaged bearings from affecting the operation of the machine.

[0003] The criteria for judging bearing damage mainly depend on two performances: one is vibration, and the other is temperature. Bearing vibration is very sensitive to bearing damage. A special bearing vibration meter can be used to measure the magnitude of the vibration, and the specific abnormality can be inferred from the frequency distribution. However, when the bearing is under-lubricated, over-lubricated, or the lubricant contains impurities, it is impossible to make a normal judgment only through the bearing vibration meter, so it is necessary to use an additional temperature detector to perform detection operations. The existing temperature detection operation generally directly detects the rotating bearing through a probe, but the bearing exposed to the outside world is easily affected by the outside temperature, which makes the detected temperature data less accurate, thereby affecting the staff's judgment on the degree of bearing wear.

[0026] Furthermore, a bearing vibration meter 1 is fixedly connected to the top of the support frame 2, an electric push rod 9 is fixedly connected to the top of the support frame 2, a vibration measuring head 11 is fixedly connected to the bottom of the electric push rod 9, the bearing vibration meter 1 is connected to the vibration measuring head 11 through a circuit line, and a detection hole is opened on the top of the fixed cover 13, which further reduces the influence of the external environment on the temperature of the bearing during operation, making the temperature detection data more accurate.

[0027] Furthermore, a fixed block 5 is fixedly connected to the other side of the support frame 2, a decibel meter 7 is fixedly connected to one side of the fixed block 5, a sound measuring tube 19 is passed through and fixedly connected to the other side of the fixed cover 13, and the side of the sound measuring tube 19 away from the fixed cover 13 is slidably connected to the sound receiving port on the back side of the decibel meter 7, which can play a role in assisting the detection of abnormal sounds and improving the accuracy of detection.

[0028] Furthermore, the moving mechanism includes a motor 2 14 and a threaded rod 15, the rotating shaft end of the motor 2 14 is fixedly connected to one end of the threaded rod 15, the bottom of the fixed cover 13 is fixedly connected to a fixed rod 16, the bottom of the fixed rod 16 is fixedly connected to a threaded block 17, the inner wall of the threaded hole in the middle of the threaded block 17 is threadedly connected to the surface of the threaded rod 15, and a moving groove 18 is opened at the top of the base 8, the side surfaces of the fixed rod 16 and the threaded block 17 are respectively slidably connected to the side surfaces of the top and bottom ends of the moving groove 18, and the two ends of the threaded rod 15 are respectively rotatably connected to the two sides of the inner wall of the moving groove 18, and the side surfaces of the motor 2 14 are fixedly inserted into the inside of the base 8, so as to facilitate the fixing operation of the fixed cover 13, thereby creating a relatively closed detection space for the bearing.

The temperature detector 12 can use the temperature measuring tube 20 to centrally measure the change of the temperature of the bearing during the rotation process. Through the bearing vibration meter 1, the decibel meter 7 and the temperature detector 12, the degree of wear of the bearing can be better judged, thereby determining the cause of the bearing wear.
