LOW NOISE GEAR FOR VEHICLES ENGAGED IN DELIVERY AFFECTED POPULATION IN EMERGENCIES in temporary accommodation

摘要

The invention relates to transport mechanical engineering and can be used to reduce the noise level of the different transmissions. The technical result - increase the damping properties of the gear. This is achieved in that the toothed wheel, comprising a crown with a concentric inner cylindrical surface of the hub and the vibration-damping member in the form of symmetrically disposed concentric rings arranged with an interference fit in the annular grooves, and a rim of flexible material disposed between the ring and the inner surface of the crown, wherein a groove formed on the inner surface of the ring from its end, and the resilient ring is made, each of the elastic rings made in the form of at least two elastic koaksil flax arranged rings, inner and outer, fixedly interconnected by at least two symmetrical elastic, diametrically opposite, elements with a through central groove, symmetrically disposed inside the element, wherein the side surfaces defining the elements, as well as the central slots are inclined with respect to the axes of the outer and inner rings and central through-slots are symmetrically arranged inside the elastic elements are filled with a damping element reticulated polyurethane injection prefecture, a hub mounted shaft on which is formed a longitudinal keyway for attaching the drive gear to the equipment elements and the gaps between the shaft and rings filled vibration damping material, for example elastomer or polyurethane.
