JF0338 Automobile wheel hub bearing grease low temperature torque tester
Introduction: The low-temperature torque tester for automotive wheel bearing grease is suitable for measuring the running performance of grease in specially manufactured, spring-loaded automotive wheel bearing assemblies under low temperature conditions. The test principle is to fill the grease sample into a special In the manufactured automobile wheel hub bearing assembly, the device assembly is first heated and then immersed at -40°C. In addition, other test temperatures can be set according to the requirements of the grease specification. The spindle runs at a speed of 1r/min, and the torque value that prevents the hub from rotating when it runs to 60s is measured. Features: 1. Standard built-in and outside tapered roller bearings, LM67010-LM67048 and LM11949 2. Microcomputer temperature controller, temperature control range from normal temperature to -50 ℃ 3. pt100 temperature sensor, the acquisition accuracy is high ± 0.5 ℃ 4. Imported compressor cascade refrigeration, low noise. 5. The transmission motor adopts a high-speed ratio, 1740/1, which can maintain a stable speed. 6. The low temperature box is insulated with special materials, and there is no temperature influence on the outside. 7. Digital display torque value. 8. The loading spring can withstand the pressure of 500N, and is equipped with a set of pressure calibration device. 9. Digital display working time and bj. 10. A set of standard greaser. technical parameter Applicable standards: NB/SH/T0839, ASTM D4693 Refrigeration method: Danfoss dual compressor refrigeration Temperature control range: normal temperature~-50℃ Time control: digital time timer Speed control: 1r/min Torque test: digital dynamometer Torque* degree: 0.1* Working power supply: AC220V 50HZ Machine power: 1000W Loading quality: 400N
