The friction and wear characteristics of gears in vacuum were investigated. The gear testing machine of power circulating type with a vacuum chamber was developed, in which the coeffiiet of friction between the contacting tooth surfaces, and the temperatures of the gear teeth and the shaft can be measured under various running conditions. The running test for S45C, SUS440C, MoS_2 coated SUS440C, Duracon and Nylon gears were carried out in air and vacuum environment by using the gear tsting machine, and the coefficient of friction between the contacting tooth surfaces, the wear of the gear teeth and temerature changes of the gear teeth, the shaft, etc. were measured. On the basis of these tesults, the friction and wear characteristics of gears in vacuum were determined to a considerable extent.The main results obtained from this investigation are summarized as follows.1. The coeficient of friction of S45C gears in vacuum is larger than that in air, but that of SUS440C gears in vacuum is smaller and those of MoS_2 coated SUS440C, Duracon and Nylon gears in vacuum are almost equal to those in air.2. The efficiency of S45C gears in vacuum is lower than that in air, but those of SUS440C, MoS_2 coated SUS440C, Duracon and Nylon gears in vacuum are almost equal to those in air.3. The amounts of wear of S45C and SUS440C gears in vacuum are smaller than those in air, but those of MoS_2 coated SUS440C, Duracon and Nylon gears in vacuum are almost equa to those in air.4. The life against the scoring of gears s improved considerably by coating the solid film lubricant on the tooth surfaces.Thus the friction and wear characteristics of gears in vacuum was determined, and the useful data for the design of gears in vacuum environment obtained from this investigation.

研究了真空环境下齿轮的摩擦磨损特性。本文介绍了一种带真空室的动力循环式齿轮试验机，它能在各种工况下测量齿轮齿面间的摩擦系数和齿轮齿与轴的温度。利用齿轮试验机对S45C、SUS440C、MoS_2涂层SUS440C、Duracon和Nylon齿轮在空气和真空环境中进行了运转试验，测量了接触齿面间的摩擦系数、轮齿的磨损量以及轮齿和轴等的温度变化。在此基础上，对真空中齿轮的摩擦磨损特性进行了一定程度的研究，主要结果如下：1. S45C齿轮在真空中的摩擦系数大于空气中的摩擦系数，而SUS440C齿轮在真空中的摩擦系数小于空气中的摩擦系数，MoS_2涂层SUS440C、Duracon和Nylon齿轮在真空中的摩擦系数与空气中的摩擦系数基本相等. S45C齿轮在真空中的效率低于空气中的效率，而SUS440C、MoS_2涂层SUS440C、Duracon和Nylon齿轮在真空中的效率与空气中的效率基本相当. S45C和SUS440C齿轮在真空中的磨损量小于空气中的磨损量，而MoS_2涂层SUS440C、Duracon和Nylon齿轮在真空中的磨损量与空气中的磨损量基本相当.在齿轮齿面涂敷固体膜润滑剂后，齿轮的抗擦伤寿命大大提高，从而测定了真空环境下齿轮的摩擦磨损特性，为真空环境下齿轮的设计提供了有用的数据。
