Abstract
Elastomeric rubber bearing for being connected between two bodies. The bearing employs an element having a series of resilient elements connected together by a series of interposed rigid elements. The thickness of the resilient elements and the width of the cross-section of the resilient and rigid elements vary in relation to the position of the elements.
Claims14
An elastic bearing comprising:
- a resilient member;
- first attaching member for attaching a first body to said resilient member;
- second attaching means for attaching a second body to said resilient member;
- and
- said resilient member comprising:
- a plurality of resilient elements and a plurality of rigid elements;
- said plurality of resilient elements being alternately positioned relative to said plurality of rigid elements such that each adjacent pair of resilient elements is separated by one rigid element;
- said plurality of resilient elements and said plurality of rigid elements defining a symmetrical axis;
- each said resilient element defining an average radius measured from said symmetrical axis;
- said plurality of resilient elements and said plurality of rigid elements comprising truncated conical elements;
- each said resilient element being configured to define a linear dimension along a straight line segment of its conical surface, such linear dimension of each said resilient element having a magnitude inversely related to the square of its corresponding average radius;
- each said resilient element defining a generally constant thickness having a magnitude inversely related to its corresponding average radius;
- each said linear dimension of each said resilient element having two extreme ends and a midpoint between the two extreme ends;
- each average radius of each said resilient element being a radius measured from the midpoint of said linear dimension to said symmetrical axis;
- and
- each said resilient element being configured to define a generally constant thickness having a magnitude inversely related to its corresponding average radius as 1/R where R is the corresponding average radius.

The bearing according to clam 8, further comprising:
- said first line intersecting a straight line segment defined by the inner surface of said first armature at a third angle,
- said second line intersecting said straight line segment defined by the inner surface of said first armature at a fourth angle;
- and
- said third angle being substantially greater than said fourth angle.
