Abstract
A tribological system, including a main body and a sandwich lubrication, wherein the sandwich lubrication includes a binder-free solid lubricant layer including a solid lubricant, and a lubricant layer including a lubricant. The binder-free solid lubricant layer and the lubricant layer are present as separate layers on the main body and the mass ratio of solid lubricant to lubricant is at most 0.05:1. The solid lubricant includes polytetrafluoroethylene (PTFE), metal sulfide, graphite, graphene, boron nitride (hexagonal), calcium phosphate, silicate, layered silicate, or mixtures thereof.
Claims15
A tribological system, comprising a main body and a sandwich lubrication, wherein the sandwich lubrication includes:
- a binder-free solid lubricant layer comprising a solid lubricant, and
- a lubricant layer comprising a lubricant,
- wherein the binder-free solid lubricant layer and the lubricant layer are present as separate layers on the main body and wherein the mass ratio of solid lubricant to lubricant is at most 0.05:1,
- wherein the solid lubricant comprises polytetrafluoroethylene (PTFE), metal sulfide, graphite, graphene, boron nitride (hexagonal), calcium phosphate, silicate, layered silicate, or mixtures thereof, and
- wherein the tribological system is, or is located in, an antifriction bearing, a plain bearing, a transmission, a chain, a sliding guide, a joint, a ball joint, a wheel bearing of automotive vehicles, a bearing of a wind turbine, a rotating plain bearing, a ventilator bearing, a linearly guided plain bearing, a knitting machine, an axial cylindrical rolling body bearing, or an actuating and adjusting device.
A sandwich lubrication, comprising:
- a binder-free solid lubricant layer comprising a solid lubricant, and
- a lubricant layer comprising a lubricant, wherein the mass ratio of solid lubricant to lubricant is at most 0.05:1,
- wherein the binder-free solid lubricant layer and the lubricant layer are present as separate layers,
- wherein the solid lubricant comprises polytetrafluoroethylene (PTFE), metal sulfide, graphite, graphene, boron nitride (hexagonal), calcium phosphate, silicate, layered silicate, or mixtures thereof, and
- wherein the sandwich lubrication is arranged in an antifriction bearing, a plain bearing, a transmission, a chain, a sliding guide, a joint, a ball joint, a wheel bearing of automotive vehicles, a bearing of a wind turbine, a rotating plain bearing, a ventilator bearing, a linearly guided plain bearing, a knitting machine, an axial cylindrical rolling body bearing, or an actuating and adjusting device.
A method of manufacturing a tribological system, comprising the steps of:
- providing a main body;
- applying a binder-free solid lubricant layer comprising a solid lubricant on the main body;
- applying a lubricant layer comprising a lubricant on the main body provided with the binder-free solid lubricant;
- and
- configuring the tribological system as or arranging the tribological system in an antifriction bearing, a plain bearing, a transmission, a chain, a sliding guide, a joint, a ball joint, a wheel bearing of automotive vehicles, a bearing of a wind turbine, a rotating plain bearing, a ventilator bearing, a linearly guided plain bearing, a knitting machine, an axial cylindrical rolling body bearing, or an actuating and adjusting device,
- wherein the mass ratio of solid lubricant to lubricant is at most 0.05:1, such that the binder-free solid lubricant layer and the lubricant layer are present as separate layers on the main body, and
- wherein the solid lubricant comprises polytetrafluoroethylene (PTFE), metal sulfide, graphite, graphene, boron nitride (hexagonal), calcium phosphate, silicate, layered silicate, or mixtures thereof.
