Marine large dismountable and self-lubricating rolling bearing device

Abstract

A marine large dismountable and self-lubricating rolling bearing device comprises a bearing inner ring, a bearing outer ring, a roller, a dismountable retainer, a pressurization oil tank, an oil tankelectromagnetic valve, a pressurization pump and an external control set, wherein the dismountable retainer is arranged between the bearing inner ring and the bearing outer ring, and roller swim ringtype sealing rings are arranged in pocket holes of the dismountable retainer and disposed on two sides of the bearing; the pressurization oil tank communicates with the swim ring type sealing rings through the oil tank electromagnetic valve and communicates with the pressurization pump; the oil tank electromagnetic valve is arranged on the lower side of a tank body of the pressurization oil tank and electrically connected with the external control set; the pressurization pump communicates with the pressurization oil tank and communicates with the swim ring type sealing rings; and the externalcontrol set is electrically connected with the oil tank electromagnetic valve, the pressurization pump and the swim ring type sealing rings. By the adoption of the dismountable retainer, when a certain part of the rolling bearing is abraded or damaged, the dismountable retainer can be opened, the abraded or damaged part is replaced, and overall replacement is not needed. The sealing rings are provided with a self-lubricating device so that the stable oil pressure in the bearing can be maintained and the service life of the bearing can be prolonged.

Description

Technical field [0001] The invention relates to a rolling bearing for ships, in particular to a large detachable and self-lubricating rolling bearing device for ships. Background technique [0002] Rolling bearings are generally composed of inner rings, outer rings, rolling elements and cages. At the same time, as a national standard part, it has high machining accuracy and high strength, and has a wide range of applications in agriculture, industry and shipbuilding. At present, the cages of rolling bearings are generally connected by rivets. In order to prevent the cage from being dislocated due to vibration, the rivet connections generally use interference fit, which is a non-detachable connection. Once a component of the rolling bearing is worn or damaged, the entire rolling bearing must be replaced as a whole, resulting in a waste of resources and limiting the application of the rolling bearing. However, the maintenance of bearings in normal use is very important, and the lu...

Problems solved by technology

[0006] The present invention is aimed at the fact that the cage of the existing large-scale bearing device for ships is usually connected by rivets. When a certain component of the rolling bearing is worn or damaged and cannot be repaired, a rolling bearing with detachable cage and self-lubricating is designed.
