Plastic part, specifically a cage for a bearing, consisting of a radiation-crosslinkable plastic material, and method for the production thereof
View Patent ↗A plastic part, especially a bearing part, specifically a cage for receiving rolling bodies of a bearing. The body of the plastic part is essentially made of a radiation-crosslinkable plastic material. Pigments that undergo a visible change during the irradiation are mixed in with the plastic material. Also, a method is disclosed for producing a plastic part, especially a bearing part, specifically a cage for receiving rolling bodies of a bearing the plastic part that has a body made of a radiation-crosslinkable plastic material.
1. A plastic part, comprising:
a body of a radiation-crosslinkable plastic material admixed with radiation-crosslinkable plastic pigments that undergo a visually verifiable change during irradiation,
wherein the plastic part is a bearing part, the bearing part being a cage.
2. The plastic part as claimed in claim 1 , wherein the pigments comprise a powder of glasses, precious stones or semiprecious stones.
3. The plastic part as claimed in claim 1 , wherein the pigments comprise organic pigments.
4. The plastic part as claimed in claim 1 , wherein the body has a surface and a type of the pigments varies with a distance from the surface.
5. The plastic part as claimed in claim 1 , wherein the pigments are inducible to become luminescent by the irradiation.
6. The plastic part as claimed in claim 5 , wherein the pigments are inducable by phosphorescent or fluorescent irradiation.
7. A method for producing a plastic part having a body of a radiation-crosslinkable plastic material, comprising the steps:
admixing pigments in the radiation-crosslinkable plastic material as an irradiation indicator,
wherein the plastic part is a bearing part, the bearing part being a cage.
8. A method for producing a plastic part having a body of a radiation-crosslinkable plastic material, comprising the following steps:
providing a mixture of the radiation-crosslinkable plastic material and a pigment; and
radiation-crosslinking the mixture,
wherein the plastic part is a bearing part, the bearing part being a cage.
