Claims
- 1. A pin having a central longitudinal pin axis and being adapted for connecting machine elements with each other, which pin comprises a metal shell and a core therein, said core consisting essentially of fully hardened, oil-fast matrix system of an epoxide resin system having a glass transition temperature above 200.degree. C. and at least about 55 percent by volume of the total core volume of a reinforcing granular filler material embedded in said system.
- 2. The pin of claim 1, wherein the amount of said granular filler in the core ranges from about 65 to about 70 percent by volume of the total core volume.
- 3. The pin of claim 1, wherein said granular filler is selected from quartz sand and amorphous quartz.
- 4. The pin of claim 1, wherein the thickness of the shell is in the range of from about 1 to 10% of the pin diameter.
- 5. The pin of claim 4, wherein the thickness of the shell is in the range of from 3 to 6% of the pin diameter.
- 6. The pin of claim 1, wherein the epoxide resin system is a fully cured mixture of
- (a) polyfunctional epoxide resin monomer,
- (b) hardener therefor, and
- (c) from 0 parts by weight to an effective amount of catalyst.
- 7. The pin of claim 6, wherein the
- component (a) is selected from the group consisting of
- triglycidyl isocyanurate,
- 1,1,2,2-tetra(4-glycidyloxy-phenyl)-ethane,
- 1,1,3-tri(4-glycidyloxy-phenyl)-propane,
- epoxynovolak,
- N,N,N',N'-tetraglycidyl-4,4'-diaminodiphenylmethane and
- N,N,O-triglycidyl-p-hydroxyaniline;
- component (b) is selected from the group consisting of
- methylnadic anhydride (methyl-norbornen-2,3-dicarboxylic anhydride),
- nadic anhydride (norbornen-2,3-dicarboxylic
- phthalic anhydride, /anhydride),
- benzophenone tetracarboxylic dianhydride,
- pyromellitic dianhydride,
- hexahydrophthalic anhydride,
- maleic anhydride,
- diaminodiphenylmethane and
- diaminodiphenylsulfone; and
- component (c) is a catalyst selected from the group consisting of
- N-methylimidazole, 2-phenylimidazole and
- N,N-dimethyl-benzylamine.
- 8. The pin of claim 7, wherein component (a) consists of 100 parts by weight of triglycidyl isocyanurate,
- the hardener component (b) amounts to from 130 to 190 parts
- by weight, and component (c) amounts to from 0 to 4 parts by weight.
- 9. The pin of claim 8, wherein component (b) is methylnadic anhydride.
- 10. The pin of claim 8, wherein component (b) is hexahydrophthalic anhydride.
- 11. The pin of claim 8, wherein component (b) is maleic anhydride.
- 12. The pin of claim 24, wherein component (c) is N,N-dimethyl-benzylamine present in an amount of from 0.5 to one part by weight.
- 13. The pin of claim 8, wherein component (c) is 1-methylimidazole present in an amount of from 0.5 to one part by weight.
