Abstract
Abstract A substantially rigid bearing mounting for rotary bodies, especially for balancing machines comprises, in addition to the main supporting rods, sets of auxiliary supporting means which are controllable, for example, by a piston cylinder arrangement to vary their frictional force transmitting ability, whereby the resonant frequency of the entire structure may be varied or controlled.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
200 words
In a substantially rigid bearing mounting, comprising a bearing housing defining a bearing center and a bearing main axis extending through said center, base means, spring rod support means for supporting said bearing housing on said base means, said spring rod support means comprising a plurality of bendable spring rods which are rigid with regard to tensile stress, pressure and buckling forces and which are located so as to uniformly restrain said bearIng housing against rotation about said main axis and against movement in any radial direction and to permit wobbling motions of a test body supported in said bearing housing about axes extending perpendicularly to each other and through said bearing center, whereby said housing, said test body, said base means and said spring rod support means (3, 4, 5, 6) form a vibratable system, the improvement comprising additional supporting means (7 to 14) arranged between said bearing housing and said base means (1) in such positions as to permit said wobbling motions, said additional supporting means including variable force transmitting means and control means (19, 20, 21, 22) operatively connected to said variable force transmitting means for varying said force transmitting means to temporarily detune said vibratable system.
Claim 2
Dependent Claim
200 words
In a substantially rigid bearing mounting, comprising a bearing housing defining a bearing center and a bearing main axis extending through said center, base means, spring rod support means for supporting said bearing housing on said base means, said spring rod support means comprising a plurality of bendable spring rods which are rigid with regard to tensile stress, pressure and buckling forces and which are located so as to uniformly restrain said bearIng housing against rotation about said main axis and against movement in any radial direction and to permit wobbling motions of a test body supported in said bearing housing about axes extending perpendicularly to each other and through said bearing center, whereby said housing, said test body, said base means and said spring rod support means (3, 4, 5, 6) form a vibratable system, the improvement comprising additional supporting means (7 to 14) arranged between said bearing housing and said base means (1) in such positions as to permit said wobbling motions, said additional supporting means including variable force transmitting means and control means (19, 20, 21, 22) operatively connected to said variable force transmitting means for varying said force transmitting means to temporarily detune said vibratable system.
Claim 3
Dependent Claim
51 words
The bearing mounting according to claim 1, wherein said additional supporting means comprise rod means, means for rigidly connecting one end of said rod means to said base means, said variable force transmitting means comprising friction coupling means for connecting the other end of said rod means to said bearing housing.
Claim 4
Dependent Claim
133 words
The bearing mounting according to claim 2, wherein each of said rod means comprises a pair of rods the lower ends of which are rigidly connected to said base means and the upper ends of which comprise friction surfaces, said friction coupling means comprising a bar connected with its upper end to said bearing housing and reaching with its lower end between said friction surfaces, and wherein said control means comprise hydraulic piston cylinder means including a piston rod extending through said friction surfaces and through said lower end of said bar, said piston rod having an outer end protruding from said fork and means for securing said outer piston rod end to the adjacent upper rod end for clamping the lower bar end into frictional, force transmitting contact with said friction surfaces.
Claim 5
Dependent Claim
101 words
The bearing mounting according to claim 1, wherein said plurality of bendable spring rods comprise four spring rods for each bearing housing arranged in pairs, whereby the pairs extend at a right angle relative to each other in said common plane, and whereby the rods of each pair are spaced from each other in said common plane, said additional supporting means comprising rod means arranged on both sides of said common plane at equal spacings therefrom and along a plane extending substantially intermediate and in parallel to the respective pair of spring rods as well as perpendicularly to said common plane.
