Description

Technical Field

[0001] The utility model relates to the technical field of abnormal sound detection of deep groove ball bearings, in particular to a detection device for abnormal sound of deep groove ball bearings. Background Art

[0002] Deep groove ball bearings are the most widely used rolling bearings. They have the characteristics of low friction resistance and high rotation speed. They can be used on parts that bear radial loads or combined loads of radial and axial loads. They can also be used on parts that bear axial loads. When producing deep groove ball bearings, in order to ensure the quality of deep groove ball bearings, it is necessary to detect abnormal sounds generated during the operation of deep groove ball bearings, so corresponding abnormal sound detection devices are required.

[0003] Reference publication number CN206601237U discloses a bearing vibration detection device, which includes a frame, a rotating shaft, a motor, a three-jaw chuck fixture, a clamping claw arranged on the three-jaw chuck fixture, an abutment assembly, and a detection device arranged on the frame for detecting the vibration of the bearing. The clamping claw includes a fixed rod slidably connected to the three-jaw chuck fixture, a movable rod slidably connected inside the fixed rod, and a limiting member for limiting the sliding position of the movable rod is arranged on the side wall of the fixed rod. If the axial length of the inner ring of the bearing is large, the clamping claw cannot completely fit with the inner ring of the bearing, and the movable rod can be used to limit the sliding position of the movable rod. The movable rod is controlled to move toward the side away from the fixed rod, so that the length of the claw increases until it can fully cooperate with the inner ring of the bearing, and then the position of the movable rod is fixed by a limiting piece. In this way, the movable rod is not easy to move when the bearing is tested. This setting improves the applicability of the bearing vibration detection device to a certain extent. According to the above, although the device can be well applied, it is usually not convenient to perform vibration tests on bearings in a sealed environment, which makes the bearings susceptible to interference from the external environment, thereby affecting their detection accuracy, which often troubles people.
