Аннотация: This study presents novel findings on design and analysis of spatial screw-lever manipulators. It is offered to introduce a screw kinematic pair with variable pitch instead of a classical screw-and-nut connection with a fixed pitch in the manipulators. Using this kinematic pair, we have developed a novel model of manipulator based Показать полностьюon the structure of five-bar screw-lever mechanism. This manipulator has a single drive input and allows reproducing complex screw movement in the shape of spatial trajectory having variable pitch and curvilinear axis. The potential application of such manipulator that has a complex reproducible trajectory is for internal contouring cutting, as well as for mixing processes. The novel manipulator as distinct from known screw-lever mechanisms allows easy changing of the output link for reproduction of new trajectories. This property is essential for cutting different internal surfaces by the same manipulator. © 2017 The Authors. Published by Elsevier Ltd.
