Abstract
Abstract A floating nut mounting for a screw and nut mechanism controlling the movements of a machine tool element or the like including a nut-containing case connected to the element via a concentric tubular member formed with two spaced sets of four transverse each opposed by pairs in parallel adjacent planes, the slots being directed at right angles from one plane to the other so as to form between these planes two pivot ring portions acting as flexible couplings, the case being secured to one end of the tubular member having its other end secured to the element.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
96 words
A floating nut mounting for a screw and nut mechanism controlling the movements of a machine-tool or like element, comprising a case containing the nut, a first member driven by the nut, a second tubular member having one end secured to said case and the other end secured to said driven member, said second tubular member including two spaced sets of four transverse slots opposed by pairs in parallel adjacent planes and shifted perpendicularly to each other between adjacent pairs so as to form between these slot planes two ring portions acting as universal flexible couplings.
Claim 2
Dependent Claim
96 words
A floating nut mounting for a screw and nut mechanism controlling the movements of a machine-tool or like element, comprising a case containing the nut, a first member driven by the nut, a second tubular member having one end secured to said case and the other end secured to said driven member, said second tubular member including two spaced sets of four transverse slots opposed by pairs in parallel adjacent planes and shifted perpendicularly to each other between adjacent pairs so as to form between these slot planes two ring portions acting as universal flexible couplings.
Claim 3
Dependent Claim
49 words
A floating nut mounting according to claim 1, comprising adjustable tightening means interposed between said case and said other end of said second tubular member for prestressing axially said second tubular member with a force normally greater than the reaction efforts of said first member driven by the nut.
Claim 4
Dependent Claim
52 words
A floating nut mounting according to claim 2, comprising, between said tightening means and said case, a floating stop member including a ring having a pair of blind holes formed at diametrically opposed locations and shifted by 90* in relation to holes of the opposite face, said blind holes receiving bearing studs.
Claim 5
Dependent Claim
28 words
A floating nut mounting according to claim 3, wherein said bearing studs have part-circular contact ends, the diameter of which corresponds substantially to the length of the studs.
Claim 6
Dependent Claim
27 words
A floating nut mounting according to claim 4, comprising elastic rings, said rings being located for holding said bearing studs axially centered in said blind holes (11-12).
Claim 7
Dependent Claim
53 words
A floating nut mounting according to claim 3, comprising between said case and said first driven member a floating stop member including a ring havinG a pair of blind holes formed at diametrically opposed locations and shifted by 90* in relation to holes of the opposite face, said blind holes receiving bearing studs.
