齿轮工作平稳性精度,是衡量齿轮质量的重要因素之一,工作平稳性精度差,会使齿轮传动速比瞬时发生变化,产生冲击、振动、噪音,致使齿轮断裂破坏,影响机器寿命。如何提高平稳性精度,是从事齿轮加工技术人员的任务。多年来,笔者曾对法国、日本进口新产品中传动齿轮件进行分析,并在双碟形砂轮卧式磨齿机上用0°、15°、20°磨削法磨出的齿轮件,测出齿形及基节误差,按其数据进行比较,结果发现0°磨削法比15°、20°磨削法误差小,精度高。笔者从理论上进行了定量分析探讨,分述如下。一、齿轮齿形及基节误差分析比较以斜齿圆柱卤轮在双碟形砂轮卧式磨齿机上磨齿为分析对象,如附图所示。
The precision of gear work is one of the important factors to measure the gear quality. The poor precision of work stability will cause the gear transmission ratio to change instantaneously, which will produce shock, vibration and noise, which will cause the gear fracture and damage and affect the life of the machine. How to improve the stability of precision, is engaged in the task of gear machining technicians. Over the years, I have to France, Japan imported new products in the transmission gear for analysis, and in the two-disc grinding machine horizontal grinder with 0 °, 15 °, 20 ° grinding method of grinding gear, measured Tooth shape and base section error, according to their data were compared and found that 0 ° grinding method than the 15 °, 20 ° grinding error is small, high precision. The author from the theoretical analysis of quantitative analysis, are as follows. First, the gear tooth profile and base section error analysis Helical gear cylindrical helical gear grinder on the two-disc grinding machine as the analysis object, as shown in the figure.
