机车牵引传动装置齿啮合的工作能力,一般是通过在运行过程中定期测量其不同截面厚度的方法,根据齿几何尺寸的变化而评定的。齿啮合耐磨性的测定是个错综复杂的问题,至今尚未研究明白齿间接触的机械、物理化学及热变化过程。经验表明,不拥有磨耗过程的数据资料,就不可能十分全面而客观地评定牵引传动装置 Locomotive traction gear meshing ability to work, usually by regularly measuring the thickness of the different sections of the method of operation, according to changes in tooth geometry and assessment. Determination of tooth engagement wear resistance is a complex problem, so far no understanding of the mechanical contact between teeth, physical chemistry and thermal change process. Experience has shown that it is not possible to assess the traction gearing very comprehensively and objectively without data on the wear process
