Abstract
In a vibro-isolating joint including two rigid flanges, a flexible cylindrical member such as bellows interposed between the flanges and a plurality of limiting bolts extended through opposed through holes in the flanges, a cylindrical elastomer body is retained in each of through holes in at least one of the flanges and a hollow sleeve is concentrically integrated with the elastomer body so as to protrude one end of the hollow sleeve from an outer surface of the flange so that lock nuts on the limiting bolts engage the protruded ends of the hollow sleeves resiliently supported in the through holes, respectively to thereby provide a high axial thrust together with a vibration isolating property.
Claims11
A vibro-isolating joint, comprising:
- two rigid annular flange members, each having a plurality of through holes arranged in an axially spaced manner;
- a flexible cylindrical member interposed between said flanges;
- a plurality of limiting bolts extending through opposed through holes in said flange members, each bolt being provided with an adjustable lock nut;
- a plurality of cylindrical elastomer bodies, each retained in each of the through holes in at least one of said flange members;
- and
- a plurality of hollow sleeve members, each being concentrically integrated with each of said elastomer bodies, said hollow sleeve members having one end which protrudes from one end of said elastomer bodies;
- wherein the lock nuts arranged on the limiting bolts contact the protruded ends of the hollow sleeve members when said flexible cylindrical member expands and forces said flange members away from each other.
