运动精度是齿轮、传动装置、机器和机械的重要性能指标,它基本上确定了整个机械制造业产品的质量。运动误差是这种特性的综合指标。根据现行的技术标准资料,既可用直接法检查(用单啮仪)也可用间接法检查(通过直接检查齿轮各项配合参数)。应当指出不断努力提高效率、提高速比、可靠性及机器的紧凑性必然要不断降低齿轮传动误差。这种状况要求解决提高检查精度方面一系列的问题,包括已经知道的许多困难。这些困难在于齿轮存在着很多不连续的复杂的几何表面(限制了齿的侧面),故应检查运动量而不是几何量。运动检查可保证检查条件最大限度地接近使用条件。此外,按已知的 Motion accuracy is an important performance indicator for gears, transmissions, machines and machinery that basically determines the quality of the entire machinery manufacturing product. Motion error is a composite indicator of this property. According to the current technical standard information, either direct inspection (with a single needle device) can also be used indirect inspection (by directly checking the gear with the parameters). It should be pointed out that continuous efforts to improve efficiency, improve speed ratio, reliability and compactness of the machine must continue to reduce the gear transmission error. This situation calls for a series of problems in improving the inspection accuracy, including many already known. These difficulties lie in the fact that the gears have many discontinuous, complex geometrical surfaces that limit the flanks of the teeth, so check the amount of exercise rather than the amount of geometry. Exercise checks to ensure that the inspection conditions to maximize the use of conditions. In addition, as known
