摘要：A vibration damper for a vibrating screen is provided with tubular housing and aflexible cylinder arranged within the tubular housing, with the flexible cylinder projectingoutwardly of one end of the housing. The flexible cylinder provides a friction surfaceperpendicular to a central axis through the cylinder. The end of the cylinder opposite thefriction surface, is spaced inwardly from the adjacent end of the housing. A ram assemblyis connected to the second end of the housing. The ram assembly includes a rigidmember arranged within the housing to engage the adjacent end of the flexible cylinderand cap mounted over the second end opening of the housing. The cap is provided with acentral axial bore, at least partly threaded, into which is fitted a threaded actuating boltwhich extends therethrough and engages the rigid member. The bolt is operative uponturning to move the rigid member toward the flexible cylinder and apply an adjustableforce biasing the flexible cylinder to move the friction surface outwardly of the first endopening of the tubular housing for vibration dampening engagement with a vibratingscreen. The end of the tubular housing surrounding the friction surface end of theflexible cylinder is spaced radially outward of the flexible cylinder and limits flexing of theflexible cylinder transversely to the central axis through the tubular housing.
