Trends in the Development of Rotary Tables with Different Types of Gears

摘要

The paper presents the special solutions of rotary table drive with hybrid spiroid gear drive. The construction solutions of rotary tables were reviewed and the various construction solutions, most frequently encountered on the market, were described. Rotary table solutions are discussed for the application in numerical control machines that are the fifth axis or can be used as an independent positioning device. Many different types of rotary table solutions are available on the market where direct drive or mechanical gear transmissions of different types are used, i.e.: worm gear drive or spiroid gear drive. One of the directions for the development of the rotary table drive are the new hybrid solutions, in which different types of mechanical gear transmissions are used. The article presents the construction and the operating principles of new gear units, in which the cylindrical or conical gear with helical line of the tooth work together with the face gear. The presented solutions are protected by patent applications.
