Worm Drive Pairs Scientific School and Research Workgroup
Within the framework of the activities of the Worm Drives Scientific School and Research Workgroup operating at the University of Miskolc, several new valuable publications, Scientific Student Papers and PhD dissertations have been prepared as a result of the complex examination of the connection characteristics of modern worm drives and developments in manufacturing geometry.
Just as the computerisation of calculation procedures increases the importance of mathematical proficiency, a higher level of descriptive geometry knowledge and new approaches to geometrical developments are also required for the correct operation and innovation of increasingly sophisticated modelling software.
Topic of the research work
The subject of the research work is mathematical, including geometric and manufacturing geometry developments, which are also related to developments in the field of descriptive geometry.
Mathematical developments, new abstractions, are determined by whether the created abstraction describes the behaviour of the studied phenomena. The topic of mathematical developments is closely aligned with the direction of technological development. It is a natural expectation that new mathematical abstractions have meaning, utility and order.
Focus area
The performance of worm drive pairs is influenced by the shape of the worm and the worm gear formed by the complex geometry of the hob. The production of cylindrical and conical worms with curved profiles (primarily when grinding hardened worms) still poses a problem, which is especially evident in the production of hobs that machine the wheels connected to the conical worm.
Tasks to solve
Examination and optimisation of the difference between the mathematical definition of the tooth surfaces of the cylindrical and conical worm gear drive pair elements and the generation of production geometry, as well as the constructive development of the shape and movement geometry of tools, machining the elements of drive pairs. New types of mathematical solutions to the modelling and simulation of drive pairs and programming of the indirect method based on knowledge of tool geometry. Tools Contact Analysis and Finite Element Method analysis of the connection of the worm gear driving pairs.
