我公司生产的12Cr2Ni4A钢主动圆锥齿轮(见图1)和从动螺旋圆锥齿轮(见图2)的设计制造精度为6～7级,传递速度分别为11362r/min和8217r/min,传递功率约为150马力。渗碳淬火前,零件跳动量要求如图所示,B面着色面积分别为75%和85%以上,且沿圆周无间断。着色区域以外平面度要求亦示于图中。渗碳淬火后,两件B面平面度要求分别控制在0.05和0.02mm左右。不规定椭圆度和跳动量等,而以着色检
The design and manufacture accuracy of the 12Cr2Ni4A steel active bevel gear (see Fig. 1) and the driven spiral bevel gear (see Fig. 2) produced by our company is 6 ~ 7, the transmission speed is 11362r / min and 8217r / min respectively, 150 horsepower. Before carburizing and quenching, the requirements for part runout are shown in the figure. The colored area on the B surface is 75% and 85% respectively, and there is no interruption along the circumference. Flatness requirements outside the colored area are also shown in the figure. After carburizing and quenching, the flatness requirements of two B surfaces are respectively controlled at about 0.05 and 0.02 mm. Does not require ovality and the amount of beating, etc., and to color inspection
