Title:
SPHERICAL MACHINE ELEMENT AND METHOD OF PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2008/053801
Kind Code:
A1
Abstract:
A spherical machine element that has compact dimensions and in which a radial
load and thrust load that the element can receive are adjustable. An insertion
body (2) is inserted into an exterior body (1). On the outer peripheral surface
of the insertion body (2) are provided a first spherical surface section (4) and
a second spherical surface section (5). The first spherical surface section
(4) is constructed from a part of a spherical surface having a predetermined radius
(R1). The second spherical surface section (5) has substantially the same center
(P) as the first spherical surface section (4) and is constructed from a part of
a spherical surface that is different from the spherical surface of the first
spherical surface section (4) and has a radius (R2). On the inner peripheral
surface of the exterior body (1) are provided a recess (8a) and a recess (9a) that
correspond to the first spherical surface section (4) and the second spherical
surface section (5), respectively. The insertion body (2) rocks relative to
the exterior body (1) about the center (P).
