Claim 1
Independent Claim
207 words
A vibration isolator having two degrees of freedom and operating according to the anti-resonance principle, comprising a pendulum means, a spring arrangement and means connecting said pendulum means to said spring arrangement, said pendulum means including a pendulum rod and a pendulum weight adjustably mounted on a free end of said pendulum rod, said spring arrangement including an inner ring including attachment means for connection to a first body, an outer ring including attachment means for connection to a second body, and a plurality of curved leaf spring elements connected at one leaf spring end to said inner ring and the other leaf spring end to said outer ring, said connecting means including a first spherical pivot bearing operatively arranged between said inner ring and said pendulum rod, and a second spherical pivot bearing operatively arranged between said outer ring and said pendulum rod, whereby an end of said pendulum rod opposite said free end is supported by both said first and second spherical pivot bearings, and wherein said curved leaf spring elements are flexible so as to allow a relative motion between said inner ring and said outer ring perpendicular to a plane extending through both rings, thus in a direction parallel to said pendulum rod.
Claim 2
Dependent Claim
207 words
A vibration isolator having two degrees of freedom and operating according to the anti-resonance principle, comprising a pendulum means, a spring arrangement and means connecting said pendulum means to said spring arrangement, said pendulum means including a pendulum rod and a pendulum weight adjustably mounted on a free end of said pendulum rod, said spring arrangement including an inner ring including attachment means for connection to a first body, an outer ring including attachment means for connection to a second body, and a plurality of curved leaf spring elements connected at one leaf spring end to said inner ring and the other leaf spring end to said outer ring, said connecting means including a first spherical pivot bearing operatively arranged between said inner ring and said pendulum rod, and a second spherical pivot bearing operatively arranged between said outer ring and said pendulum rod, whereby an end of said pendulum rod opposite said free end is supported by both said first and second spherical pivot bearings, and wherein said curved leaf spring elements are flexible so as to allow a relative motion between said inner ring and said outer ring perpendicular to a plane extending through both rings, thus in a direction parallel to said pendulum rod.
Claim 3
Dependent Claim
21 words
The vibration isolator of claim 1, wherein each of said first and second spherical pivot bearings is a low-damping elastomer bearing.
Claim 4
Dependent Claim
30 words
The vibration isolator of claim 1, wherein said leaf spring elements include slots extending in a lengthwise direction of said leaf springs and thus substantially perpendicular to said pendulum rod.
Claim 5
Dependent Claim
36 words
The vibration isolator of claim 1, further comprising a flange (9) which is elastic in a lengthwise direction of said pendulum rod, said outer ring being connected to said second spherical pivot bearing by said flange.
Claim 6
Dependent Claim
38 words
The vibration isolator of claim 4, wherein said flange is a disc-like flange made of fiber-reinforced material, which is stiff in a radial direction, but elastic perpendicular to said radial direction which extends perpendicular to said pendulum rod.
