Abstract
There is provided a floating nut which opportunity of application can be expanded by increasing the floating amount of the floating nut. The clearance between the spline of an outer circumferential surface of a nut 6 and a spline opening 5b of a retainer 5 is freely set on the condition that the outside diameter df of a flange 6c of the nut 6 and the outside diameter dj of a stop ring 7 are larger than the diameter of a spline opening 5b of the retainer 5. The applications of the floating nut 4 can be extended by determining the clearance between the spline of the outer circumferential surface of the nut 6 and the spline opening 5b of the retainer 5 according to the required floating amount.
Claims8
A floating nut to support a nut passed through an opening of a retainer by floating with respect to said retainer,
- said nut comprises a number of rectangular shaped protrusions and recesses having a predetermined difference in diameter on an outer circumferential surface;
- a flange on the bottom of the nut having an outside diameter greater than the diameter of an opening of said retainer, and a stop ring having an outside diameter greater than the diameter of the opening of the retainer at a height separated from said flange by at least the thickness of the opening portion of said retainer and mounted in an attachable/detachable manner,
- wherein the opening of said retainer ensures a desired clearance between the retainer and the outer circumferential surface of said nut;
- and
- wherein each protrusion and the recess provided on the outer circumferential surface of said nut form a spline.
A floating nut to support a nut passed through an opening of a retainer by floating with respect to said retainer,
- said nut comprising a number of rectangular shaped protrusions and recesses having a predetermined difference in diameter on an outer circumferential surface;
- and
- a flange on the bottom of the nut having an outside diameter greater than the diameter of an opening of said retainer, a retainer opening having a plurality of analogous rectangular shaped recesses and protrusions into which the number of protrusions and recesses of the nut are adapted to fit so as to allow for at least some relative radial movement between the nut and retainer and a stop ring having an outside diameter greater than the diameter of opening of the retainer at a height separated from said flange by at least the thickness of the opening portion of said retainer and mounted in an attachable/detachable manner.
