Water lubrication spherical bearing for ship shaftless rim propeller

Abstract

The invention discloses a water lubrication spherical bearing for a ship shaftless rim propeller. The water lubrication spherical bearing mainly consists of a metal tile basal body, a rubber lining, a pressure disc and a shaft. The water lubrication spherical bearing is characterized in that the inner surface of the metal tile basal body is a spherical surface; rubber is vulcanized on the inner surface of the metal tile basal body by dint of a special mold; the radial section of the rubber lining is the same in thickness; and a spiral groove is formed in the rubber lining for circulating water to achieve the effects of lubricating and cooling the bearing. The water lubrication spherical bearing for the ship shaftless rim propeller is simple in structure and few in parts, can synchronously bear radial force and axial force, and is suitable for the rim propeller.

Description

technical field [0001] The invention relates to the field of ship propellers, in particular to a water-lubricated spherical bearing that can simultaneously bear radial force and axial force and is used for ship shaftless rim propellers. Background technique [0002] The shaftless rim propeller is a kind of propeller blade that is directly installed on the annular rotor of the permanent magnet motor, and the blade is driven by the motor to rotate, so as to propel the ship. Using electric energy to transmit propulsion power instead of the traditional propulsion method of complex shafting to transmit mechanical power, because the propulsion noise is much smaller than that of pump-jet propellers, it can greatly improve the stealth performance of ships. The investment of the rim thruster is very large. In a shaftless rim propeller, the bearing bears both the radial force and the thrust from the propeller, that is, the axial force. And because the duct arrangement of the rim pro...
