Abstract. Non-reversible step drives with a spring accumulator are considered, which allow reducing energy consumption when performing technological processes. Kinematic schemes of the step drive layout are analyzed, optimal designs of control units are selected, and an experimental installation of a non-reversible step drive with energy recovery is developed. Tests of a non-reversible step drive carried out with the use of the experimental installation makes it possible to compare previously obtained theoretical data with the experimental results. A comparative analysis of the time indicators of a pneumatic step drive and a drive with energy recovery is carried out. The obtained results demonstrate that the use of a spring battery can significantly reduce energy costs, and therefore application of spring drives is economically advantageous in the industrial sphere.

Keywords: rotary table, spring batteries, energy recovery, step drive, non-reversible drive
