Abstract

1,187,326. Rollers; vibration dampers. MOUNT HOPE MACHINERY Ltd. 21 May, 1968, No. 24055/68. Headings F2S and F2U. Vibration of a heavy roller comprising a stationary hollow axle 10 carrying a rotatable sleeve 12 on fluid bearings 14 or, Fig. 3 (not shown), on roller bearings (76), is damped by a paddle 70 resiliently mounted in the hollow axle. As shown, the paddle is mounted by resilient rods 68 in blocks 64 mounted on a tension rod 56 which gives the roller an initial curvature prior to application of the load. The axle is partially filled with water or other lubricating fluid and the paddle acts to pump the fluid through the clearance between itself and the axle to dampen vibration of the roller. The paddle is tuned to a natural frequency equal to that of the roller. Again, Fig. 5 (not shown), the paddle is mounted on a tension bar 56 at its centre only, tuning masses being mounted at its end. The paddle may be formed as a laminate, e.g. in the manner of a leafspring, and vibrational energy of the roller absorbed additionally by interfacial friction between the discrete layers of the laminated paddle as it vibrates.
