Abstract
The invention relates to a tribological body (10) comprising a body with a sliding surface (12) and at least one hollow space through which a fluid can flow. The body (10) consists of a first monolithic partial body (14) comprising the sliding surface (12) and of a second monolithic partial body (16) connected to the first one, wherein the hollow space is designed as a conduit (20) which runs at least in sections inside the second partial body and is delimited from the latter at least on the bottom side and the side surface sides.
Claims22
A tribological body (10, 100) such as a bearing, sliding element, in particular a sliding ring, comprising a body with a sliding surface (12, 112) and at least one hollow space through which fluid can flow,
- wherein the body (10, 100) consists of a first monolithic partial body (14, 114) comprising the sliding surface (12, 112) and of a second monolithic partial body (16, 116, 216) connected to the first one or comprising it, wherein the hollow space is designed as a conduit (20, 120, 128, 220) which runs at least in sections inside the second partial body and is delimited from the latter at least on the bottom side and the side surface sides.
A method for producing a tribological body (10, 100) such as a support, sliding element, in particular a sliding ring, comprising the method steps:
- producing a monolithic first partial body (14, 114) comprising a sliding surface (12, 112),
- producing a monolithic second partial body (16, 116) with at least one integrated conduit (20, 120, 128) or a section of such a conduit, and
- joining the first partial body to the second partial body.
The method according to claim 21, wherein, in order to connect the first partial body (14, 114) to the second partial body (16, 116), an adhesive is applied on at least one of the contact surfaces which is preferably pasty and preferably consists of one or more organic binders such as polysaccharides, lignin sulfonates, polyvinyl alcohol or reaction resin such as furans and phenols as well as one or more functional fillers such as carbon preferably in the form of carbon black or graphite powder, silicon powder, silicon carbide powder.
