Water-lubricated thrust-radial combined bearing for shaftless propeller

Abstract

The invention discloses a water-lubricated thrust-radial combined bearing for a shaftless propeller, mainly comprising a bearing housing (2), bearing liners (3) and a thrust head (4), wherein the bearing liners (3) are evenly distributed on the inner wall of the bearing housing (2) and fixed to the outer wall of the bearing housing (2) through fastening screws, and a water channel is provided between the adjacent bearing liners and is free of barriers and used to allow a flow of water to lubricate and cool the bearing; mutual acting surfaces of the inner wall of the bearing housing (2), the bearing liners (3) and the thrust head (4) are all conical surfaces, identical in conicity. The water-lubricated thrust-radial combined bearing has the advantages such as simple structure, fewer used parts and high reliability and is suitable for marine vessels running under variable conditions with inclined thrust plates and having high requirement on damping performance and bearing capacity.

Description

technical field [0001] The invention belongs to the field of ship propellers, and in particular relates to a water-lubricated sliding bearing for a shaftless rim-driven propeller that can simultaneously bear axial force and radial force, that is, a so-called shaftless propeller water-lubricated push- Diameter joint bearings. Background technique [0002] Due to the disadvantages of the traditional ship shafting propulsion system, such as complex structure, large space occupation, limited transmission efficiency, and difficulty in controlling vibration and noise, people gradually turn their attention to the more advanced shaftless rim drive propulsion system (referred to as "shaftless propulsion"). device"). The shaftless propeller adopts the integrated design of propeller-motor-rudder-bearing, the motor stator is embedded in the conduit, the blades are fixedly connected to the inner wall of the rotor, and both ends of the rotor are constrained by a water-lubricated bearing ...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: in order to overcome the deficiencies of the narrow installation space of the sliding bearing of the shaftless propeller, the inability of the traditional fixed pad bearing to realize the optimal bearing capacity under variable working conditions, and the poor vibration damping effect, to provide a Axial force and radial force, and the non-uniform thickness rubber layer is used to realize the compact structure of the shaftless propeller water-lubricated push-diameter joint bearing
