摘要
为确定双圆弧齿轮粗切后的精切余量,安排了精切前公法线长度测量工序,并推导了精切余量与公法线长度的关系式。公法线长度当量值与当量进刀量比值应在0.7～1.1之间。实践中一般精切余量为1.5mm,余量公差为±0.5mm。
In order to determine the finishing allowance of double- circular-arc gears, the author recommends a procedure for measuring the base tangent length before finishing-cut and derives the relation between the finishing allowance and the base tangent length. The ratio between the equivalent value of base tangent length and the equivalent feed should be within 0.7-1.1. It is common practice to select a finishing allowance Of 1.5mm, with a tolerance of ± 0.5mm.
