Metrical synthesis of guided needles of changeable structure is in warp – knitting machine

Purpose. Design of the target mechanism of oscillating motion the ushkovykh of needles in the warp-knitting machine with use of applied CAD – programs. Methodology. Methods of metric synthesis and the kinematic analysis of standard mechanisms of technological machines of light industry are used. Findings. The mechanism of changing structure is worked out with a stop for the drive of guide needle in a warp – kitting machine for the cycle of looping; mathematical models are got for the metrical (geometrical) synthesis of changing structure of mechanism. Originality. The analytical method of metrical (geometrical) synthesis is offered four link mechanism of changeable structure for the drive of guide needles of warp – knitting machine, incarnating law of motion with a stop for the cycle of looping. Practical value consists in development of functionally-perfect mechanisms of warp – knitting machines by reduction of amount of movable elements at maintenance of technological process of looping, that will provide reduction of the inertia loading and potentially will promote the productivity of machine
