摘要: 为选择合理的硬度配对来延长机械式履带调整器中钢蜗轮副的使用寿命,在SRVⅣ微动磨损实验机上,设计了一种研究硬度对钢蜗轮副磨损行为影响的实验方法,并利用该方法在无润滑、室温条件下考察了不同硬度配对对40CrNiMoA钢和18Cr2Ni4WA钢组成的钢蜗轮副磨损行为的影响.实验结果表明:随着蜗轮材料40CrNiMoA钢硬度的增加,40CrNiMoA钢的磨损体积减小,与之相对应的蜗杆材料18Cr2Ni4WA钢的磨损体积增大;在实验条件下,双方具有相近使用寿命的硬度配对出现在40CrNiMoA钢硬度为HRC43左右时.

Abstract:

In order to select a reasonable hardness matching for prolonging the service life of steel worm wheel pairs used in mechanical track tension adjustors,a experimental method was designed to evaluate the effect of hardness on the wear behaviors of steel worm wheel pairs on a SRV Ⅳoscillating friction and wear tester.By using this me-thod,the wear behaviors of the worm wheel pairs with different hardness matching of 40CrNiMoA steel and 18Cr2Ni4WA steel were investigated in unlubricated condition at a room temperature. Experimental results show that, in the steel worm wheel pairs composed of 40CrNiMoA steel and 18Cr2Ni4WA steel, the wear volume of 40CrNiMoA steel decreases, while that of the worm material 18Cr2Ni4WA steel increases with the increase in hardness of 40CrNiMoA steel, and that, in the applied 18Cr2Ni4WA steel have approximately equal service experimental conditions, both the 40CrNiMoA steel and the life when the hardness of 40CrNiMoA steel is about HRC43.
