Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing testing technology, specifically to a drum bearing support with bearing testing function. Background Technology
[0002] For some lifting machinery, production tasks are heavy, and the lifting and maintenance of various types of lifting machinery are used frequently in harsh environments, such as high temperature, high humidity, and high dust. In order not to affect production efficiency and ensure the normal and safe use of special equipment, technicians need to frequently check the health condition of the bearings in the drum of the lifting machinery. At present, the inspection of bearings in the drum of lifting machinery mainly relies on hearing and vision, and personnel must go to the location of the component and carry out the inspection while the equipment is running. Because of the close contact with the operating mechanism during the inspection, there is a high safety risk, and the inspection results are greatly affected by subjective factors. Utility Model Content

[0005] This utility model proposes a drum bearing support with bearing detection function, including a bearing housing, and further including a rolling bearing, a crank mechanism, and a displacement sensor measuring instrument for being sleeved on the drum shaft; the rolling bearing is mounted on the bearing housing;
[0006] A support plate is fixed to the side wall of the bearing housing, and the crank mechanism is fixed to the support plate. The displacement sensor measuring instrument is fixed to the telescopic end of the crank mechanism. When detection is performed, the crank mechanism pushes the measuring head of the displacement sensor measuring instrument to contact the end face of the rolling bearing.
[0007] Furthermore, bearing end caps are provided on both sides of the bearing housing, the bearing end caps are located on both sides of the rolling bearing, and a through hole is provided on the bearing end cap for the measuring rod of the displacement sensor measuring instrument to pass through.
[0008] Furthermore, the through hole is provided with a composite bearing that facilitates the sliding of the measuring rod of the displacement sensor measuring instrument.
[0009] Furthermore, the crank mechanism includes a crank, a drive motor fixed on the support plate for driving the crank to move, a guide rail fixed on the support plate, and a slider that cooperates with the guide rail; the output end of the crank is connected to the slider, and the displacement sensor measuring instrument is fixed to the front end of the slider.

[0012] Furthermore, the drive motor is a remote-controlled motor.
[0013] Furthermore, the displacement sensor measuring instrument is a grating ruler displacement sensor measuring instrument.
[0014] Compared with existing technologies, this invention utilizes a crank mechanism to move a displacement sensor measuring instrument until the measuring head contacts the end face of the rolling bearing. The displacement sensor measuring instrument then measures the circular runout of the rolling bearing end face towards the center, improving the safety and accuracy of the inspection process and enabling inspections without stopping the machine or production. This device can intelligently monitor the operating status of bearings in the drum section of crane machinery and display the results data to relevant terminals. Technicians can determine the bearing's operating status based on the test results, deciding whether the crane machinery can continue to be used, whether lubrication is needed, or whether the bearing needs to be replaced, while also extending the bearing's service life.
