Abstract
Abstract A rotary body supported at one or both ends by bearing means, either the body or a bearing means being resilient. An extension is located between each end of the rotary body and its respective bearing means, the extension having a smaller diameter than the rotary body and rotatable with the body. The mass per unit axial length of the extension is smaller than the mass per unit length of the rotary body.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
147 words
A rotational arrangement comprising a rotary body, support means resiliently supporting said rotary body at least at one of its ends, and a rigid extension means between the end of said rotary body and said support means for reducing the radial forces produced on said support means during rotation of said body, said extension means being rotatable with said rotary body and having a substantially smaller diameter than said rotary body, the mass per unit axial length of said extension means being less than the mass per unit axial length of said rotary body, so as to minimize any displacement of the center of gravity of said combined rotary body and extension means as compared to the center of gravity of said rotary body alone, said extension means having its only support at said support means, whereby the radial restoring forces on said support means is reduced.
Claim 2
Dependent Claim
147 words
A rotational arrangement comprising a rotary body, support means resiliently supporting said rotary body at least at one of its ends, and a rigid extension means between the end of said rotary body and said support means for reducing the radial forces produced on said support means during rotation of said body, said extension means being rotatable with said rotary body and having a substantially smaller diameter than said rotary body, the mass per unit axial length of said extension means being less than the mass per unit axial length of said rotary body, so as to minimize any displacement of the center of gravity of said combined rotary body and extension means as compared to the center of gravity of said rotary body alone, said extension means having its only support at said support means, whereby the radial restoring forces on said support means is reduced.
Claim 3
Dependent Claim
17 words
A rotational arrangement as defined in claim 1 wherein said rotary body includes only a single member.
Claim 4
Dependent Claim
17 words
A rotational arrangement as defined in claim 1 wherein said rotary body includes a plurality of members.
Claim 5
Dependent Claim
72 words
A rotational arrangement as defined in claim 1 including bearing means supporting said rotary body at both of its ends, and an extension between each end of said body and its respective bearing means, each extension being rotatable with said body and having a smaller diameter than said body, the mass per unit axial length of each of said extensions being less than the mass per unit length of said rotary body.
