Description

Technical Field

[0001] The invention relates to the technical field of bearing ball testing, in particular to a testing device for performing a high-speed rotation test on a ball inside a bearing. Background Art

[0002] In modern industrial production, bearings are widely used in many fields, so they may be damaged during use. Ball bearings are generally composed of a retainer, an outer ring, an inner ring, and a ball. The position of the ball is related to other components. Therefore, the service life of the ball in the bearing is different for different working conditions. At present, there are few tests on bearing balls at home and abroad, and there are almost no high-speed test machine accompanying test devices. Therefore, it is of great significance to make up for the accompanying test device of bearing test machines, which has guiding significance for bearing detection test machines.

[0003] Most common general bearing testers are bearing friction and wear testers, and there are fewer testers for the balls inside the bearings. Therefore, only by giving specific working conditions to the key components (balls) and allowing the balls to rotate at high speed can we get closer to the actual working conditions and obtain more accurate analysis conclusions.

[0004] Considering that the current technologies are all based on test devices for the entire bearing, the performance of the entire bearing is tested and studied, and there is no single test for each component of the bearing, resulting in inaccurate test results. In addition, when there is a problem with the bearing, it is impossible to pinpoint which component has the problem, affecting the efficiency of subsequent repair and maintenance. This device can provide a rotational speed for the balls inside the bearing for testing, so that the ball test machine can measure the analysis test closer to the actual working conditions. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a test device for performing high-speed rotation tests on balls inside bearings, which solves the problem that in the existing bearing detection process, there is no single test for each bearing component, resulting in inaccurate test results.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a test device for performing high-speed rotation tests on balls inside bearings, comprising a support frame, the top of the support frame is rotatably connected to a transmission shaft, the outer wall of the transmission shaft is fixedly connected to a coupling, the outer wall of the coupling penetrates and is rotatably connected to the top inner wall of the support frame, the outer wall of the coupling is fixedly connected to a loading wheel, the top of the support frame is equipped with a temperature sensor that can be installed and removed by bolts, and the top of the support frame is equipped with a speed sensor that can be installed and removed by bolts.

[0007] Preferably, one end of the transmission shaft is fixedly connected to a motor.

[0008] Preferably, three groups of transmission shafts are provided, and the three groups of transmission shafts include transmission shaft A, transmission shaft B and transmission shaft C.

[0009] An operating system for a test device for performing a high-speed rotation test on a ball inside a bearing, comprising a loading shaft speed control module and a sensor monitoring module, wherein the loading shaft speed control module controls the speeds of three groups of transmission shafts to test the parameters of the ball at different speeds, and the sensor monitoring module collects various parameters of the ball during the test.

[0010] Preferably, the loading shaft speed control module includes a main rotating shaft control module A, which controls the speed of a group of motors. The main rotating shaft control module A is connected to a main rotating shaft control module B, which controls the speed of another group of motors. The main rotating shaft control module A and the main rotating shaft control module B are both connected to a communication interface module, and the communication interface module is responsible for receiving control instructions from the staff, thereby further transmitting the adjustment and control commands to the main rotating shaft control module A and the main rotating shaft control module B for speed control.

[0011] Preferably, the main rotating shaft control module A includes a controller module A, to which a motor module A is connected, and the controller module A controls the output shaft rotation speed of the motor module A.

[0013] Preferably, the sensor monitoring module includes: a temperature sensor module, a noise sensor module, a vibration sensor module and a rotational speed sensor module. The temperature sensor module records the temperature value during the ball rolling test, the noise sensor module records the noise value during the ball rolling test, the vibration sensor module records the vibration amplitude during the ball rolling test, and the rotational speed sensor module records the rotational speed value during the ball rolling test.

[0014] Preferably, the temperature sensor module is connected to a temperature measuring instrument module, and the temperature measuring instrument module is responsible for displaying the temperature value collected by the temperature sensor module.

[0015] Preferably, a speed measuring instrument module is connected to the speed sensor module, and the speed sensor module is responsible for displaying the speed value collected by the speed sensor module.

[0016] Working principle: The bearing balls to be tested are placed separately on the outer wall of the loading wheel, and the staff controls two sets of motors to start them, so that the motor drives the transmission shaft to rotate, and at the same time cooperates with the synchronous belt set on the outer wall of the transmission shaft to drive the three sets of transmission shafts to rotate at the same time, so that the transmission shaft drives the coupling to rotate at the same time, and the coupling drives the loading wheel to start high-speed rotation. During the rotation of the loading wheel, the bearing balls are driven to rotate by friction, thereby simulating the working state of the bearing balls. In this way, for measuring the bearing ball tester, it can easily solve the state factors of the bearing balls under actual working conditions.

[0017] In conjunction with the operating system, the staff can adjust the speed of the three loading shafts to achieve tests under different working conditions; and through the speed sensor connected to the base assembly, as well as the temperature sensor and vibration sensor on the side, the speed, temperature and vibration data can be analyzed in real time.

The present invention is provided with a temperature sensor module, a noise sensor module, a vibration sensor module and a speed sensor module, so that various parameters of the bearing balls can be recorded during the rotation of the bearing balls, which is conducive to judging the quality of the bearing balls from multiple aspects and ensuring the accuracy of the detection.

[0020] 3. The present invention is provided with a loading shaft speed control module, so that the speeds of the three groups of loading wheels can be adjusted according to the needs of the staff, so as to test the balls under different working conditions and improve the testing space and adaptability.
