Abstract
Abstract A homokinetic coupling comprising an inner ring (3) with axial grooves (6) engaged by the flats on flattened balls (8) whose spherical sides are partly enclosed in (conical) recesses (10) of ball-like elements (1) which are movably locked up in cylindrical pockets (12, 13) of the outer ring (1, 2). Due to the arrangement, the grooves (6) of the inner ring (3) are arcs having the same centre as the inner ring (3) which simplifies the formation of said grooves as well as the manufacture of the outer ring (12).

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
152 words
Homokinetic coupling comprising a housing or outer ring having a cavity limited by a spherical surface and open toward the outside at least at one edge and an inner ring, placed within this cavity, having an outer surface formed by a spherical surface, and a set of balls, flattened at one edge, each of which is accomodated at one edge in grooves, extending in axial direction, made in the spherical surface of the inner ring, the bottoms of which form a rolling surface along which the balls are capable of moving by the flattened edge, and at the other edge are accomodated rotating by the spherical edge in a recess forming a part of the housing, characterized in that the housing (1,2) comprises a plurality of rotating ball-shaped elements (11), wherein in each element (11) is formed a recess (10) in which the spherical edge of a ball (8) is partially accomodated.
Claim 2
Dependent Claim
152 words
Homokinetic coupling comprising a housing or outer ring having a cavity limited by a spherical surface and open toward the outside at least at one edge and an inner ring, placed within this cavity, having an outer surface formed by a spherical surface, and a set of balls, flattened at one edge, each of which is accomodated at one edge in grooves, extending in axial direction, made in the spherical surface of the inner ring, the bottoms of which form a rolling surface along which the balls are capable of moving by the flattened edge, and at the other edge are accomodated rotating by the spherical edge in a recess forming a part of the housing, characterized in that the housing (1,2) comprises a plurality of rotating ball-shaped elements (11), wherein in each element (11) is formed a recess (10) in which the spherical edge of a ball (8) is partially accomodated.
Claim 3
Dependent Claim
38 words
Homokinetic coupling according to claim 1, characterized in that each ball-shaped element (11) is placed rotating in a cavity fixed in relation to the housing (1,2), the grooves (6) in the inner ring (3) having a constant depth.
Claim 4
Dependent Claim
21 words
Coupling according to claim 1 or 2, characterized in that the recess in the ball-shaped elements (11) is tapered running [inward].
Claim 5
Dependent Claim
78 words
Coupling according to claim 2 or 3, characterized in that the ball-shaped elements (11) are accomodated in round openings formed by two half round openings (12,13) adjacent to one another, which are formed in the housing (1) and in a retaining part (2) of the housing, respectively, which retaining part (2), with interconnection of a ring (15) covering the round openings (12,13) and the ball-shaped elements (11) placed therein from the outside, is connected with the housing (1).
