Abstract

When modernizing drives and machines, it is generally difficult to achieve significant improvements across all areas critical to operation. The modernization of a single-support contactless drive system involves design changes that improve a number of characteristics and properties, which means that they are complex in nature. Primarily, this involves reducing the rotating masses and the total mass of the drive, increasing the stiffness and load-bearing capacity of the support and rotor, ensuring the stability of the drive’s rotation at all speed regimes and under any type of external load, and reducing operating costs (consumption of process air, electrical power, etc.). Based on an analysis of the characteristics of aerostatic supports, areas for improvement were proposed, and the modernization of a single-support aerostatic drive system was realized. This involved transitioning from a symmetrical double-conical design to an asymmetrical conical-ring design, in which the ring-shaped support surface, acting as a support, carries the main load.
