Abstract
Abstract A polymeric component (1) having a bore (2) to receive a shaft (3), the component (1) having, in the zone (4) around the bore (2), substantially plane and parallel end faces disposed perpendicular to the bore axis, the component being clamped between substantially radial abutment surfaces (5,6) of the shaft (3), characterized in that a number of axially continuous metal pins (7) distributed over the periphery are disposed in the zone (4) around the bore (2) and bear by their ends on the abutment surfaces (5,6) and a method of producing the same.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
91 words
A polymeric component (1) having a bore (2) to receive a shaft (3), the component (1) having, in a zone (4) around the bore (2), substantially planar and parallel end faces disposed perpendicular to the axis of the bore, the component being clamped between substantially radial abutment surface (5,6) characterized in that a number of axially continuous metal pins (7) are distributed radially outward of said of the bore (2) and are disposed in the zone (4) around the bore (2) and bear by their ends on the abutment surface (5,6).
Claim 2
Dependent Claim
91 words
A polymeric component (1) having a bore (2) to receive a shaft (3), the component (1) having, in a zone (4) around the bore (2), substantially planar and parallel end faces disposed perpendicular to the axis of the bore, the component being clamped between substantially radial abutment surface (5,6) characterized in that a number of axially continuous metal pins (7) are distributed radially outward of said of the bore (2) and are disposed in the zone (4) around the bore (2) and bear by their ends on the abutment surface (5,6).
Claim 3
Dependent Claim
24 words
A polymeric component (1) of claim 1 wherein the ends of the metal pins (10) are reduced as compared with the full pin cross-section.
Claim 4
Dependent Claim
16 words
A polymeric component of claim 2 wherein the ends of the metal pins have points (11).
Claim 5
Dependent Claim
35 words
A polymeric component (1) of claim 1 wherein the bore (2) is formed with a keyway (8) and metal pins (7) are disposed one on each side of the keyway in an immediate vicinity thereof.
Claim 6
Dependent Claim
28 words
A process for the production of a polymeric component (1) of claim 1 characterized in that the metal pins (7) are surrounded by the polymeric substance by injection-moulding.
Claim 7
Dependent Claim
25 words
A process for the production of a polymeric component (1) of claim 1 characterized in that the metal pins (7) are subsequently introduced into bores.
Claim 8
Dependent Claim
16 words
A polymeric component of claim 2 wherein the ends of the metal pins have cutting edges.
Claim 9
Dependent Claim
26 words
A process for the production of a polymeric component (1) of claim 1 wherein the metal pins (7) are surrounded by the polymeric substance by casting.
