Embodiment approach

[0040] 1. If image 3 As shown, wherein the lower surface of the rubber layer 3-2 and the upper surface of the lower tile base 3-1 are plane. The space angle formed by the lower surface of the rubber layer 3-2 and the vertical plane passing the bearing axis is not equal to 90°, and the rubber layer 3-2 becomes thinner and thinner along the shaft rotation direction. The specific parameters of the rubber layer can be optimized according to the actual working conditions, and the optimization goal is the maximum bearing capacity.

[0041] 2. If Figure 4 As shown, the lower surface of the rubber layer 3-2 is a circular arc surface, and the two are also tightly connected through the vulcanization process, and the rubber layer 3-2 becomes thinner and thinner along the axis of rotation. The parameters of the arc surface should be optimized according to the actual working conditions, and the optimization goal is the maximum bearing capacity.

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 ...
