ABSTRACT:
A rotary control damper is described that includes a rotor comprising a spur gear and a plurality of rotary cylindrical bodies coaxially provided on a lower face of the spur gear. The damper also includes a stator comprising a plurality of stationary cylindrical bodies coaxially provided on an upper face of a base. The stationary cylindrical bodies rotatably engage the rotary cylindrical bodies of the rotor. An annular protrusion is provided on an outer periphery of the outermost outer race of the rotary cylindrical bodies. The protrusion engages a protrusion provided on the base of the stator outside the outermost inner race of the stationary cylindrical bodies. In addition, it slidingly engages the annular protrusion of the rotor in a direction of rotation of the rotor. The protrusion has a downward inclination face provided on at least one of the engaging faces between the annular protrusion and the engaging protrusion. A gap is formed which, between the rotary cylindrical bodies and the stationary cylindrical bodies, is filled with an oil.
