Development of Constructive Scheme and Mathematical Model of Plate Oscillations of the Needle Thread Tension Regulator with Three-Stage Shock Absorbers in a Sewing Machine

Abstract

The article presents a constructive scheme and principles of operation of the needle thread tension regulator of a sewing machine. The mathematical model of axial oscillations of the plates of the needle thread tension regulator of the stiffness characteristics of three-stage stake shock absorbers and their dissipative properties at changes in the needle thread tension is derived. The results of analytical method of solving the problem of plate oscillations of the thread tension regulator are given.
