Tooth Surface Model Construction and Error Evaluation for Toothtrace Modification of Helical Gear by Form Grinding
摘要
Abstract
When grinding of helical gears with tooth to tooth,contact lines changed all the time, the additional movement caused the tooth to produce “distortions of modification”.Based on the facts, this paper presented a high precision establishment method of tooth flank.Firstly,the actual contact line equation of form grinding was derived by the principles of tooth to tooth.Secondly,changing the center distance values,getting multiple sets of contact line along the tooth and NURBS surface fitting was used to get tooth flank of tooth surface.Thirdly,studying the main factors affecting the accuracy of tooth surface deviation of tooth profile and helix deviation and the evaluation model of tooth errors was proposed.Then,in a longitudinal case study of drumshaped tooth helical gear,the tooth flank of the entire process was described.Finally,by grinding experiments the accuracy of error prediction and high accuracy of tooth surface were verified.关键词
