Vibration damper for rotor housings
First Claim
1. A vibration damper for a rotor housing made of a housing material, said vibration damper comprising a damping band made of an elastic material having a high coefficient of friction against said housing material, and a clamping band comprising a material having a different modulus of elasticity than said housing material, wherein said damping band is arranged in a frictionally contacting and contour fitting manner on an outer circumferential surface of said housing, and said clamping band is arranged in a contour fitting manner on an outer circumferential surface of said damping band to secure said damping band to said housing.

Abstract
A vibration damper for rotor housings includes a rubber-elastic damping band (6) that encircles the outer circumference of the rotor housing (4) in a contour fitting manner. A clamping band (7) encircles the damping band (6) and secures the damping band to the housing (4). The clamping band is made of a material having a different modulus of elasticity than the material of the rotor housing, which achieves a detuning of the vibrational system including the rotor housing and the vibration damper as components. Such a detuning reduces the vibrational tendency of the rotor housing. Frictional rubbing between the damping band and the housing surface, and between the damping band and the clamping band effectively damps or dissipates the energy of any vibration that does occur. The clamping band includes a tension adjustment element that is adjustable and releasable so that the clamping band and the entire vibration damper may easily be removed from the housing for carrying out maintenance and inspection procedures.
