Abstract

The invention discloses a ship stern tube bearing dismounting device which comprises a stern tube, a bearing, a first connecting rod, a second connecting rod, a supporting device and a driving mechanism. The bearing is installed in the stern tube. A threaded groove is formed in one end of the first connecting rod. A threaded column is arranged at one end of the second connecting rod. The threaded groove end of the first connecting rod and the threaded column of the second connecting rod are inserted into two ends of the bearing respectively. The threaded groove of the first connecting rod and the threaded column of the second connecting rod are connected in the bearing in a threaded mode. The supporting device is installed below the outer-side end of the second connecting rod. The driving mechanism is fixed to the lower end of the outer side of the first connecting rod. Two limiting rings are arranged on the first connecting rod and the second connecting rod respectively. The limiting ring is connected to the outer side of the end of the bearing in an abutting mode. The ship stern tube bearing dismounting device is ingenious in whole structural design, quick and convenient to assemble and efficient in operation.

Description

technical field [0001] The invention relates to the field of marine accessories, in particular to a dismantling device for a ship stern tube bearing. Background technique [0002] Nowadays, in the construction process of large, medium and small ships, the installation of the bow and stern bearings of the stern tube is the top priority at the berth stage. The bearing is correctly pressed into place, and at the same time, the clearance between the shaft and the bearing, the cleanliness of the shaft hole, the cleanliness of the oil, and the load of the shafting are measured later to meet the process requirements, so that the ship can sail smoothly. During the construction process or long-term operation of the ship, the replacement of the bearing is also a major difficulty, and the bearing needs a professional device to disassemble the bearing. Due to the inconsistent types and sizes of various ship bearings, not all of them have matching professional devices. Some factories u...
