Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Such as Figure 1 to Figure 5 As shown, the thrust integrated water-lubricated bearing for the rim propeller of the present invention includes a rotor support ring 1 , a bearing body 2 , radial pads 3 , and axial pads 4 .

[0028] The rotor support ring 1 is equipped with 2 pieces in the rim propeller, and is connected with the motor rotor and both ends of the blade. The load is transmitted in the way that the outer ring 5 and the end face 6 of the rotor support ring 1 with the spiral water groove 1 7 and the spiral water groove 2 8 are respectively connected with the bearing block 2 20 and the axial bearing block 2 on the radial pad 3 of the thrust integrated water-lubricated bearing The bearing block one 16 on the tile 4 makes contact.

[0029] The rotor support ring 1 is only the structure on the left side of the rim propeller, and the rim p...

Abstract

Two rotor supporting rings are symmetrically arranged on the left side and the right side of a motor rotor, spiral water grooves are formed in the rotor supporting rings in the axial direction and the flange plane correspondingly, and the rotating direction of the spiral water groove in the rotor supporting ring on the left side is opposite to that of the spiral water groove in the rotor supporting ring on the right side; an active water flow channel can be formed, dovetail groove structures are uniformly distributed on the inner cavity and the end face of the bearing body, radial tiles are mounted in radial dovetail grooves in the dovetail groove structures, and axial tiles are mounted in axial dovetail grooves in the dovetail groove structures; a plurality of radial bushes are assembled into a radial bearing, a plurality of axial bushes are assembled into an axial bearing, grooves are reserved between the radial bushes and are aligned with mounting gaps between the axial bushes, and a water lubrication groove channel of the thrust integrated water lubrication bearing is formed. The compactness, the cooling performance, the reliability, the installation convenience and the lubricating effect of the water lubricated bearing can be improved, and high-level application of the rim propeller is promoted.

Description

technical field [0001] The invention relates to a ship power propulsion system, in particular to a thrust water lubricated bearing for an edge propeller. Background technique [0002] With the rapid development of electric propulsion systems, rim thrusters, as a new type of propulsion, are favored by shipowners and research institutions for their advantages of high efficiency and low noise. The blades of the rim propeller are directly driven by the motor and supported by water-lubricated bearings, which not only avoids the power loss caused by traditional propeller gears and shaft transmission, but also avoids the leakage of lubricating oil caused by oil lubrication, pollution problem. Water-lubricated bearings are key components of rim propellers, and their performance directly determines the reliability and equipment life of the propeller itself. The existing water-lubricated bearings of rim thrusters have the following deficiencies: [0003] 1. Since the water-lubricat...
