DEVICE FOR REDUCING NOISE IN GEAR WHEEL COUPLINGS,WITH A HIGH SAFTY DEGREE

摘要

A highly safe device for reducing noise produced in gear wheel couplings in the motion transmission and distribution lines of wrapping and packeting machines operated at very high output speed. Two co-axial and opposite gears have the same number of angularly coincident teeth, one of the gears being formed of rigid metal material and the other consisting of tough and elastically yielding material.
