Abstract
A coaxial joint for joining inner and outer cylindrical members permitting rotational and/or linear movement between them, comprises an outer bushing sleeve non-rotatably receivable within the outer cylindrical member, an inner bushing sleeve formed with a central bore for receiving the inner cylindrical member; a first group of longitudinally-extending, circumferentially-spaced ribs formed between the inner and outer sleeves; and a second group of such ribs formed in staggered relationship with respect to the first group on the outer face of the outer sleeve and effective, when forcibly received within the outer cylindrical member, to distort inwardly the portions of the outer sleeve between the first group of ribs and thereby to minimize the distortion of the inner sleeve.
Claims20
A coaxial joint for joining an inner cylindrical member to an outer cylindrical member by means of a bushing disposed therebetween, characterized in that said bushing includes:
- an outer sleeve non-rotatably receivable within said outer cylindrical member;
- an inner sleeve formed with a central bore for receiving said inner cylindrical member;
- a first group of longitudinally-extending, circumferentially-spaced ribs formed between said inner and outer sleeves with each such rib having a width which is substantially smaller than the circumferential spacing between ribs;
- and a second group of longitudinally-extending, circumferentially-spaced ribs each also having a width which is substantially smaller than the circumferential spacing between ribs, said second group of ribs being formed in staggered relationship with respect to said first group of ribs on the outer face of said outer sleeve and effective, when forcibly received within said outer cylindrical member, to distort inwardly the portions of said outer sleeve between said first group of ribs and thereby to minimize the distortion of said inner sleeve.
A coaxial joint for joining an inner cylindrical member to an outer cylindrical member by means of a bushing disposed therebetween, said bushing including:
- an outer sleeve non-rotatably receivable within said outer cylindrical member;
- an inner sleeve formed with a central bore for receiving said inner cylindrical member;
- a first group of longitudinally-extending, circumferentially-spaced ribs formed between said inner and outer sleeves with each such rib having a width which is substantially smaller than the circumferential spacing between ribs;
- and a second group of longitudinally-extending, circumferentially-spaced ribs each also having a width which is substantially smaller than the circumferential spacing between ribs, said second group of ribs being formed in staggered relationship with respect to said first group of ribs on the outer face of said outer sleeve and effective, when forcibly received within said outer cylindrical member, to distort inwardly the portions of said outer sleeve between said first group of ribs and thereby to minimize the distortion of said inner sleeve;
- said bushing consisting of two sections each of a hard plastics material, namely an inner section comprising said inner sleeve, and an outer section comprising said outer sleeve and said two groups of ribs formed on its inner and outer faces, respectively.
