Analyze and Correct Model for Machining Involute Spline

摘要

The rolling technic of involute spline has many advantages. This method can increase the production efficiency, has no cutting, can improve the metal structure of machining surface to increase the quality of surface and prolong the life of product, so the technic is used extensively in the industry of automobile and tractor. The design model of spline outline is built according to the formative theory of equidistant spiral surface by means of meshing principle of involute spline, roller is manufactured and machining spline is test according to the model. The correction of spline outline is accounted by means of measuring the outline of spline in three-coordinates measuring machine and comparing the measuring data and the data of ideal involute spline. The spline is remachined in corrected roller and ideal spline shape is gotten.
