Abstract
A noise reducing device for a track chain arrangement in which a pair of track chains are trained around a sprocket. The noise reducing device reduces noise arising when the track chains come into engagement with sprocket teeth and includes a pair of annular supporting brackets secured to the opposite sides of the sprocket, a plurality of resilient members secured to the radial outer surfaces of the aforesaid pair of annular supporting brackets, and a pair of resilient metal hoops secured to the resilient members in concentric relation to the sprocket. The metal hoops are elastically deformed when the track chains engage the sprocket teeth.
