Abstract A weight screw rod type damper in which a cylindrical main case is provided with a closure and a fixing part at one end, and a cylindrical auxiliary case provided with fixing part at one end, and a small diameter threaded hole at the other end is inserted into the main case to be free to move axially inward and outward. A screw rod engaged rotatably in the closure of the main case near the fixing part, threadably engages the small diameter hole of the auxiliary case near the middle part of the rod and rotatable clockwise and is counterclockwise with the relative movement of the auxiliary case outward and inward of the main case and a cylindrical weight is fixed directly or through an accelerating device to the screw rod or an extension thereof.
A weight screw rod type damper comprising a cylindrical main case provided with a closure and a fixing part at one end and an open opposite end, a cylindrical auxiliary case provided with a fixing part at one end, and a closure at the opposite end having a small diameter threaded hole therein, said auxiliary case being inserted into the main case with its end closure facing the closure of the main case so as to be free to move axially inward and outward, a screw rod engaged rotatably in the closure of the main case, said screw rod threadably engaging the hole of the closure of the auxiliary case near the middle part thereof and being rotatable clockwise and counter-clockwise with the relative movment of the auxiliary case inward and outward of the main case and a cylindrical weight within the fixing part of the main case operably connected to the screw rod whereby upon a vibration being transmitted to the damper, the weight may be rotated by the reciprocation of the screw rod.
