本文介绍用EA(镍铬-铐铜)热电偶嵌在齿轮轮齿上,通过刷环引电器来测量运转接触过程中的螺旋锥齿轮轮齿表面基础温度(也有人称为轮齿准稳态表面温度或轮体温度等).并对影响齿轮轮齿表面基础温度的一些因素如齿轮的工作转速、工作载荷和齿轮润滑油的供油温度、供油压力、供油方式的变化作了些试验研究.从获得的试验结果看出,齿轮的工作转速、工作载荷和润滑油的供油温度的变化对齿轮轮齿表面基础温度有明显的影响;而润滑油的供油压力、供油流量在正常工作范围内变化和供油方式的变化对齿轮轮齿表面基础温度的影响不甚明显.
This article describes the use of EA (nickel-chromium - handcuffed copper) thermocouple embedded in the gear teeth through the brush ring electrical contactors to measure the process of contact spiral bevel gear tooth surface temperature (also known as gear quasi-steady surface Temperature or wheel temperature, etc.) Some tests were also made on some factors that affect the basic temperature of gear tooth surface, such as the working speed of the gear, the working load, the oil supply temperature of the gear oil, the oil supply pressure and the oil supply method From the test results obtained, it can be seen that the change of working speed, working load and oil supply temperature has a significant effect on the temperature of gear tooth surface. However, the lubricating oil supply pressure, Changes in the normal working range and changes in fuel supply on the surface of the gear tooth surface temperature is not obvious.
