Profile determination of a tube-straightening roller by envelope theory
Journal of Materials Processing Technology, 1999Abstract A simple method by applying envelope theory to determine the profile of a tube-straightening roller has been studied. The roller profile is defined as the envelope of a three-parameter family of spatial curves. The three parameters are rotation, translation and rotation, which generate by their motions the spatial curves. The envelope theory

Time-varying mesh stiffness analysis of a single-roller enveloping hourglass worm gear
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2018As a new type of transmission, the single-roller enveloping hourglass worm gear (SEHWG) is widely used in precision mechanical transmission systems. Time-varying mesh stiffness (TVMS) is one of the most important excitations, which has great influences on the dynamic characteristics of SEHWG systems.
