- Abstract
The temperature distribution of gear tooth surface is one of the key indicators for evaluating the thermal management and lubrication design of gear transmission system, and the experimental measurement of gear surface temperature has become an important part of gear transmission system research. In view of the need for real-time and on-line measurement of surface temperature of rotating gears, this paper designs a transverse plane of oil-jet-lubrication rotary gear temperature measurement test rig based on contact thermocouple and non-contact infrared pyrometer. In this design, the thermocouple is welded to the transverse plane of the rotating gear and rotates with it, and the temperature measurement value is transmitted to the external receiving concentrator through a wireless signal transmitter fixed at the end of the measuring gear shaft. An air-purging tube for blowing out the oil mist on the infrared temperature measuring optical path is designed and connected to the front end of the infrared pyrometer, which is used to reduce the influence of oil mist and other impurities in the test chamber on the infrared temperature measurement results. The experimental results show that the two methods of thermocouple and the infrared pyrometer can effectively measure the teeth surface temperature of oil-injected lubrication gear under three different rotating speeds, and the maximum temperature difference between the two methods is not exceed 5 ℃. The measurement methods and analysis conclusions of this test have good reference value for the design analysis and test verification of gear transmission system under complex working conditions.
