FIELD: machine building.
SUBSTANCE: invention relates to vacuum process equipment. Harmonic tight drive includes tightly connected casing and made as single part installation flange, bottom and input and output links, flexible tight link deformed by the external elliptical generator of waves of forced deformation, made in form of two peak contour and installed in contour of the flexible bearing, flexible tight link, two-wave toothing made by rims of the engaging wheels. Output, flexible tight and input links are made with double supports, flexible tight link is divided and made assembled from fixed, installed one on another with relative mobility of bolted thin-wall enclosures, and are provided with individual functions. The flexible tight enclosure executes function of tightness assurance, and internal non-tight enclosure executes function of the power load transfer. Invention describes device and sequence of operations of assemblage/disassemblage of harmonic tight drive and scope of its application.
EFFECT: reduced amplitudes of links vibration, increased links rigidity, vibration stability and strength, increased tightness and drive service life.
