Copper bush of bearing seat of anchor machine

Abstract

The invention provides a copper bush of a bearing seat of an anchor machine. The copper bush comprises a cylinder body, wherein the cylinder body is in a hollow cylinder structure, a through hole in the middle of the cylinder body is an axial hole, cylindrical baffling blocks are respectively arranged at two ends of the cylinder body and are integrated with the cylinder body, and the end faces of the cylindrical baffling blocks and the cylinder body are level with each other; an annular groove is formed in the middle of the cylinder body, and the section of the annular groove is a semicircular arc of which the radius is 5mm. The copper bush has the beneficial effects that the baffling blocks are arranged at two ends of the copper bush, and the copper bush is driven to rotate when a main shaft of the anchor machine rotates, so that the axial play of the main shaft of the anchor machine is avoided due to the action of the baffling blocks; meanwhile, the annular groove is formed in the middle of the cylinder body, and the radial cooperation of the copper bush and the main shaft is guaranteed due to the screwing depth of a screw on the bearing seat, so that the operation of the main shaft of the anchor machine is safe and reliable.

Description

technical field [0001] The invention relates to a copper sleeve of a windlass bearing seat. Background technique [0002] Windlass, as a mechanical device for retracting and releasing anchors and chains on ships, retracts and releases anchor chains through the rotation of its main shaft. The operation of the main shaft determines whether the anchor chain is stable or not. Chain jumping, abnormal fall, etc., will cause impact on the windlass and seriously damage the windlass. The main shaft of the windlass is installed on the base of the windlass by means of a bearing seat, and a copper sleeve is generally provided between the bearing seat and the main shaft to protect the main shaft and reduce friction. necessary. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention develops a copper sleeve of a windlass bearing seat, which includes a copper body, the copper body is a hollow cylinder structure, and the through h...
