Description
Summary:The article presents the development and justification of parameters of the new design of the sewing machine needle mechanism with elastic coupling, which provide an increase in speed modes of operation while reducing operating costs. As well as new scientific results obtained based on theoretical and experimental studies. A new design of the needle mechanism of a sewing machine with an elastic connection is developed and the problem of the dynamics of the needle mechanism with an elastic connection is solved by taking into account the dynamic and mechanical characteristics of the engine, inertial, elastic-dissipative parameters of the mechanism, as well as the resistance force of the sewn materials by the sewing machine. The dependences of the parameter changes in the function on the resistance force of the cross-linked materials are obtained.
