Supporting capability of the press joint with curved grooves in the junction

摘要

By the example of press joint with curved grooves in the junction new structuring concept of interference joints is shown. Using this concept it is possible to increase the fit supporting capability according to the torque and axial force. Elastostatic joint model is shown which allows to define analytically the elastic deformation wave height contact pressure value in junction and to evaluate supporting capability of joint. Some quantitative influence investigation results of form dimensions, grooves position on joint quality are given.
