Patent number: 8839958Abstract: A method and a device for screening aggregates and/or soils with a screening deck, where each point of the screening deck revolves continuously in the same rotating direction along a circular path. This movement is effected by the fastening frame of the screening deck being bearing-mounted upon at least two eccentric shafts, where each eccentric shaft is in turn bearing-mounted on a device body with bearings, through the midpoints of which extends a rotation axis of the eccentric shaft. Additionally, a throw axis spaced from the rotation axis of the eccentric shaft extends through the midpoints of bearings present between each eccentric shaft and the fastening frame, so that when the device is in operation, the throw axis revolves around the rotation axis along a circular path continuously in the same direction. All mass forces of movable structural components have been balanced with respect to rotation axes.Type: GrantFiled: October 10, 2012Date of Patent: September 23, 2014Assignee: Salmonbay Consulting OyInventor: Markku Jonninen

Patent number: 5620101Abstract: A trommel separator includes a clutch mechanism that operates with a shaft mounted right angle gear reducer for direct drive of the drum and a flexible mount. The clutch mechanism has a clutch slip disk which is located between first and second disks. The first disk receives the torque from the shaft mounted gear reducer which is then transferred to the second disk, which is rigidly connected to a rotating drum, when the first and second disk are pulled together. A clutch regulating system, namely jam nuts and a spring coil, are connected to the first and second disks through shafts for pulling the first disk and the second disk together. The flexible mount has a mount which rests upon a pivot plate for rotating the mount around a vertical axis. A first and second plate is attached to the gear reducer and horizontally rotatable within the mount. Clips keep the mount from lifting off a frame and spacers prevent the clamping of the mount. Pads are also used to prevent wear of the clips.Type: GrantFiled: December 6, 1994Date of Patent: April 15, 1997Assignee: Andela Tool and Machine, Inc.Inventors: Cynthia Andela, James Andela
