齿轮在使用的过程中,齿面经常出现压陷和剥落,有的齿轮甚至工作几小时后就发现齿面有压陷(图1)。为排除这一故障,本文以具体实例分析,研究故障原因及鼓形齿的设计问题,作一简要介绍。 (一) 压陷故障的特点: 我们所研究的齿轮,其模数m=2毫米,齿数Z=15,齿顶高系数,f=0.8材质为12C_rNi4A渗 Gear in the process of use, the tooth surface often appear depression and peeling, and some even found gear tooth surface after a few hours of depression (Figure 1). In order to eliminate this failure, this article analyzes the specific examples to study the cause of the malfunction and the design of drum-shaped teeth, make a brief introduction. (A) the characteristics of depression fault: The gear we studied, the modulus m = 2 mm, the number of teeth Z = 15, tooth top high coefficient, f = 0.8 material 12C_rNi4A seepage
