Autonomous heat dissipation type bearing sleeve for marine rotating shaft

Abstract

The invention discloses an autonomous heat dissipation type bearing sleeve for a marine rotating shaft. The autonomous heat dissipation type bearing sleeve comprises a bearing outer shell, a rubber lining body, a built-in supporting ring sleeve and a flowing type heat conduction mechanism. In order to achieve heat dissipation of the rubber lining body, a cavity needs to be formed in the rubber lining body for heat conduction oil heat dissipation, however, when the cavity is formed in the rubber lining body, the connection strength of the rubber lining body is reduced, and therefore a hard built-in supporting ring sleeve with the strength improved is arranged in the rubber lining body; heat dissipation is carried out through heat conduction oil in an annular heat conduction cavity in a built-in supporting ring sleeve, the heat conduction oil in the annular heat conduction cavity can be replaced regularly, and regular heat dissipation of the rubber lining body is achieved.

Description

Technical Field

[0001] The invention belongs to the field of ship accessories manufacturing, and in particular relates to a self-heating type bearing sleeve for a ship rotating shaft. Background Art

[0002] Marine rubber bearings use rubber as their main component and are used to support the shaft and sleeve. They are manufactured using a molding method and are mainly used in ship axial flow pumps, deep well pumps, etc. as supports for blades and pump blades. Existing rubber bearing sleeves generally include a metal outer shell and a rubber lining. The rubber lining is installed around the inside of the metal outer shell. The rotating shaft is inserted into the metal outer shell and the rotating shaft is in contact with the rubber lining around it. When the rotating shaft is operating, the rotating shaft will rotate at a high speed, and the outer side of the rotating shaft will rub against the inner side of the rubber lining around it. When the friction lasts for a long time, a large amount of heat will be generated. Once the heat makes the temperature high, the rubber lining will be deformed, and the connection stability and sealing of the rotating shaft and the rubber lining will deteriorate. Therefore, being able to dissipate heat from the rubber lining regularly will greatly reduce the probability of deformation of the rubber lining. Therefore, it is necessary to design a heat dissipation structure for the rubber lining to improve its heat dissipation performance. Summary of the invention
