Adjustment of the main kinematic chains of heavy vertical lathes
Journal Title: Proceedings in Manufacturing Systems - Year 2018, Vol 13, Issue 1
Abstract
In this paper the variants of adjusting of the main kinematic chains from the vertical lathes (carousel) are presented. Different possibilities of driving with electric motors are presented in a comparative manner by means of gearbox type gearboxes and belt or tooth belt transmissions. The paper presents the control systems used in older electric motors with a single speed, but also modern systems, in which asynchronous current motors are used having conntonously speed adjustment by frequency variation. It is emphasized the current role of gearboxes which is that of torque amplification and not of speed reduction. It is presented the criteria for choosing the optimal variant from a technical and economical point of view, depending on the specific technological requirements. Some experimental achievements are presented in heavy machine tools from the families of normal and vertical lathes (carousel) for the fabrication and re-fabrication of lathes, which can process pieces having diameters ranging from 800 to 10 000 mm.
