Abstract
A sliding bearing device is proposed which comprises a bearing seating having a first sliding surface and a bearing body having a second sliding surface, wherein the bearing body is accommodated by the bearing seating and the first sliding surface and the second sliding surface face each other, wherein the bearing seating and/or the bearing body is made of an open-pore fiber composite material at least in a sliding region which forms the respective sliding surface.
Claims18
Sliding bearing device comprising:
- a bearing seating having a first sliding surface;
- and
- a bearing body having a second sliding surface;
- wherein the bearing body is accommodated by the bearing seating and the first sliding surface and the second sliding surface face each other;
- wherein at least one of the bearing seating and the bearing body is made of an open-pore fibre composite material at least in a sliding region which forms the respective sliding surface;
- and
- wherein at least one of (i) fibres of the fibre composite material are arranged in the sliding region such that the fibres end at the associated sliding surface at an acute angle to the sliding surface, and (ii) fibres of the fibre composite material run parallel to the respective sliding surface.
Turbopump or turbine or free piston motor, comprising at least one sliding bearing device, said at least one sliding bearing device comprising:
- a bearing seating having a first sliding surface;
- and
- a bearing body having a second sliding surface;
- wherein the bearing body is accommodated by the bearing seating and the first sliding surface and the second sliding surface face each other;
- wherein at least one of the bearing seating and the bearing body is made of an open-pore fibre composite material at least in a sliding region which forms the respective sliding surface;
- and
- wherein at least one of (i) fibres of the fibre composite material are arranged in the sliding region such that the fibres end at the associated sliding surface at an acute angle to the sliding surface, and (ii) fibres of the fibre composite material run parallel to the respective sliding surface.
