Abstract

This adjustable rotary type viscous damper include s shaft 1 journaled in fixed housing 2. Drum 3 is keyed to an end of shaft 1 for rotation within housing 2. Drum 3 includes one or more recesses 4 forming a plurality of concentric cylindrical surfaces 5. Cap 6 is provided with a series of spaced cylindrical sleeves 7 protruding from one surface. Cap 6 is placed on the open end of housing 2 with sleeves 7 protruding into recesses 4 of drum 3 between adjacent surfaces 5. The interior of housing 2 is filled with a lubricating fluid. The position of cap 6 can be adjusted radially of housing 2 to vary the amount of eccentricity of sleeves 7 and, at the same time, adjust the spacing between sleeves 7 and the cylindrical surfaces of recesses 7.

Adjustable Rotatory Type Viscous Damper

This adjustable rotary type viscous damper include s shaft 1 journaled in fixed housing 2. Drum 3 is keyed to an end of shaft 1 for rotation within housing
2. Drum 3 includes one or more recesses 4 forming a plurality of concentric cylindrical surfaces 5. Cap 6 is provided with a series of spaced cylindrical sleeves 7 protruding from one surface. Cap 6 is placed on the open end of housing 2 with sleeves 7 protruding into recesses 4 of drum 3 between adjacent surfaces 5. The interior of housing 2 is filled with a lubricating fluid. The position of cap 6 can be adjusted radially of housing 2 to vary the amount of eccentricity of sleeves 7 and, at the same time, adjust the spacing between sleeves 7 and the cylindrical surfaces of recesses 7. The amount of damping force exerted by this device is a function of the spacing between the adjacent surfaces of the sleeves and recesses which can be varied by adjusting the position of cap 6.
