VIBRATION ISOLATING SPINDLE SUSPENSION Russian patent published in 2018 - IPC D01H7/08 

FIELD: textile and paper.

SUBSTANCE: invention relates to textile machinery, in particular to pendants of spindles of spinning machines. This is achieved by the fact that in the vibration isolating suspension of a spindle containing elastic elements located in the spindle beam between the spindle support flange and the end face of the beam, an elastic element located in the upper part of the spindle beam is made in cross section in the form of a T-bush located between the spindle support flange and the end surface of the spindle beam fixed from turning around its axis by means of a pin fixed in the spindle beam and entering with a gap into the support flange of the spindle, and elastic elements located in the lower part of the spindle beam are made in the form of an elastic washer, pressed through a rigid washer by means of a spring through the end face of the nut interacting with the threaded part of the spindle suspension, the elastic elements are made of a three-dimensional mesh weave, wherein the density of the mesh structure of the elastic mesh elements is within the optimum range of values of 1.2…2.0 g/cm³, herewith the wire material of the elastic mesh elements is EI-708 steel, its diameter is within the optimum range of 0.09…0.15 mm, and the pin fixed in the spindle beam and fixing the elastic element from turning is made vibration damping in the form of a hollow cylindrical damping element, to the ends of which flat stops are rigidly attached, and the inner cavity is filled with a set of at least two damping discs mounted on an elastic axis coaxially disposed with a cylindrical shell of the damping element, and between the damping discs there is at least one cylindrical helical spring, the cavity of which is filled with a vibration damping material, for example, polyurethane.

EFFECT: higher efficiency of vibration isolation in the resonance mode, simplified design and assembling are provided.
