Der Rotorwelle (1) ist zumindest ein mit einem Medium (21) befüllbarer Hohlraum (3; 11, 12, 13, 14, 16, 17, 18, 19, 22, 23, 24) derart zugeordnet, dass Unwuchten der Rotorwelle (1) in ihrem Drehbetrieb reduziert sind.
Abstract:
A system for reducing vibrations in a rotating system uses a variable viscosity medium (26) that is redistributed in a housing (20) connected to the rotating system (2). Specifically, the medium is responsive to a control signal that is generated as a function of rotational speed of the rotational system. The control signal activates a triggering device that promotes a change in viscosity of the medium such that it is distributed within the housing in a manner that reduces vibratory loads.
Abstract:
An adaptive balance system is described for adaptively balancing a mass rotating about an axis of rotation. The system comprises a plurality of reservoirs for containing fluid and arranged around a centre substantially coincident with the axis rotation in use. A conduit arrangement interconnects fluid reservoirs to allow the flow of fluid therebetween. A pump arrangement is connected by the conduit arrangement between fluid reservoirs for pumping the fluid from each fluid reservoir to another fluid reservoir through the conduit arrangement.
Abstract:
The invention relates to tyre balancing compositions having improved balancing properties comprise a visco-plastic gel and solid bodies having an average smallest dimension in the range of 0.5-5 mm; preferably 1-4 mm, more preferably around 3 mm. When applied in a layer to the inside of a motor vehicle tyre, the compositions act by allowing the solid bodies move through the gel and to concentrate in areas to counteract imbalances. The solid bodies preferably have an average ratio alpha between their smallest and their largest dimension of alpha , preferably 600-2000 kg/m , in particular 700-1000 kg/m , especially 800-900 kg/m ; they may be made from polyolefins, polystyrene, polyvinyl chloride, polyamide, rubber or glass. The weight ratio between the solid bodies and the gel is from 10:1 to 1:10, preferably from 5:1 to 1:5, in particular from 2:1 to 3:1, such as from 1:1 to 1:2. The invention further concerns a tyre balancing kit and a method for balancing automobile wheel assemblies.

Abstract:
The invention relates to an automatic balancing centrifugal apparatus by fluid compensation, which compensates a load imbalance among buckets holding samples by injecting a fluid into the buckets or sucking the fluid from the buckets, thereby simplifying the overall structure of the centrifugal apparatus, increasing the durability, and centrifuging a large quantity of samples under various high-speed rotation conditions smoothly. The automatic balancing centrifugal apparatus by fluid compensation comprises: rotors on which a plurality of buckets are mounted; a centrifuge motor for rotating said rotors; a load measurement mechanism, which is installed so as to lift and lower along the rotation trace of said buckets and which measures the load of said buckets while the restraint of the buckets is being released at the time of lifting; a position sensing mechanism for sensing whether or not each of said buckets is positioned right above said load measurement mechanism; a fluid compensation mechanism for injecting a fluid into said buckets or for sucking the fluid from the buckets; and a main control part for controlling the overall operations of each of said elements and for controlling said fluid compensation mechanism so that the loads of said buckets can become equal to each other.
