| 摘 要： | 为了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SRV Ⅳ 微动磨损试验机上，设计了一种能实现硬度对钢蜗轮副磨损行为影响研究的试验方法。并利用该方法在无润滑，室温条件下考察了硬度对40CrNiMoA钢和18Cr2Ni4WA钢组成的钢蜗轮副磨损行为的影响。试验结果表明：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；在试验条件下，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，可延长机械式履带调整器中钢蜗轮副的使用寿命。

| Abstract: | In order to prolong the service life of steel worm pairs used in track tension adjustor, a test method was designed to evaluate the effect of hardness on the wear behavior of steel worm gear on a SRVⅣoscillating friction and wear tester. Through this method the wear behavior of 40CrNiMoAsteel -18Cr2Ni4WA steel with different hardness matching was studied under dry sliding condition at room temperature. The results show that in the steel worm gear pair composed of 40CrNiMoA steel and 18Cr2Ni4WA steel, the wear volume loss of 40CrNiMoA steel decreases and that of the worm material increases with the hardness of 40CrNiMoA steel increasing. When the hardness of 40CrNiMoA steel is about HRC43, wear volumes of the worm specimen is equal to that of the gear specimen. Based on the experimental results, reasonable hardness matching for prolonging service life of track tension adjustor was proposed. |
