Description

Technical Field

[0001] The utility model relates to the technical field of bearing grease low-temperature torque test equipment, in particular to a grease low-temperature torque tester detection device. Background Art

[0002] At present, in the low-temperature torque test of ball bearing grease, the American ASTM D1478-2007 and the Chinese SH / T0338 ball bearing grease low-temperature torque test methods are used. In these two test methods, a dynamometer is used in the test machine to measure the torque. According to the provisions of the test standard, the test device must be installed with the test bearing after reaching the predetermined temperature (generally -50°C or -70°C). The timing starts when the temperature continues to cool to the predetermined temperature. The temperature is kept constant for two hours, and then the drive motor is started. The dynamometer pointer is immediately observed. Generally, it takes several seconds to tens of seconds to read the maximum value. The maximum value reached by the pointer is recorded, and this value is used to calculate the starting value. The test shaft is rotated for 60 minutes (while maintaining a constant temperature), and the average reading of the dynamometer pointer is observed within 15 seconds after 60 minutes, and the operating torque is calculated based on the average value. Therefore, the test personnel must wait for the cooling to reach the predetermined temperature to start timing after the experiment begins, and then wait for two hours to start the transmission mechanism, record and calculate the starting torque value; then wait for another hour, and record the average reading again within the last 15 seconds and calculate its torque as the test result. In this way, the test personnel must pay attention to the test progress at least within 3 hours. Once the data reading time is missed, the experiment fails. Moreover, the data reading time is relatively hasty, and there are inevitable errors in manual reading. In addition, the data measured by the dynamometer has large errors and low precision, resulting in inaccurate test structure.

[0003] However, current bearing fixing devices can only fix bearings of specified sizes. When bearings of different sizes need to be fixed, the clamping components need to be replaced, which is time-consuming and laborious.
