一、概述细齿花键连结是机械零件中常用的一种固定连结形式,广泛应用于汽车、拖拉机上。据统计,汽车、拖拉机产品上细齿花键有许多是采用齿数Z=36或48,模数一般为m=0.7～1.0,压力角α=45°(见图1)。细齿花键轴的加工,近代国外已广泛采用无屑加工的冷滚轧或冷搓工艺。国内在大量生产中仍采用滚齿工艺。细齿花键的精度在产品图上用中径公差表示,公差值一般在0.03～0.084mm 之间,在大量生产中,用一对专用花键环规检验,其中综合花键环规具有整圈键齿,用以控制花键的
First, an overview Spline spline is a commonly used mechanical parts of a fixed form of connection, are widely used in cars, tractors. According to statistics, many of the fine serrations in automobile and tractor products adopt the number of teeth Z = 36 or 48, the modulus is generally m = 0.7 ~ 1.0, and the pressure angle α = 45 ° (see Figure 1). Fine-tooth spline shaft processing, modern foreign countries have been widely adopted cold rolling or cold rolling process without rubbing. In the mass production is still using hobbing process. The precision of serrated spline is indicated by the diameter tolerance in the product drawing. The tolerance value is generally between 0.03 and 0.084mm. In mass production, a pair of special spline ring gauges are to be tested. The integrated spline ring gauge has Whole circle key teeth, used to control the spline
