Embodiment Construction

[0022] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] like Figures 1 to 5 As shown, a press-fit marine bearing includes a bearing sleeve 1 and a pressure-resisting mechanism 2; the bearing sleeve 1 is in an annular sleeve structure, and a shaft cavity 13 is arranged inside the bearing sleeve 1; the pressure-resisting mechanism 2 is set There are multiple; the two ends of the bearing sleeve 1 are provided with a plurality of installation grooves 11; the inside of the installation groove 11 is provided with a thread groove 12; the thread groove 12 communicates with the shaft cavity 13; A pressing mechanism 2 is respectively installed in the installation groove 11, such as figure 2 As shown, four pressing mechanisms 2 can be evenly distributed, and four pressing blocks 24 are used to support and limit the rotation shaft; Drive plate 22, annular elastic body 25; said external thread cylinde...

Abstract

The invention discloses a press-fit-type marine bearing which comprises a bearing sleeve and an abutting mechanism; the bearing sleeve is of an annular sleeve body structure, and a shaft cavity is formed in the bearing sleeve; and the abutting mechanism comprises an outer threaded cylinder, an inserting rod, an abutting block, a driving plate and an annular elastic body. The inserting rod is inserted into a connecting threaded hole and an inserting channel from a T-shaped inserting opening, then the outer threaded cylinder is mounted on a threaded groove through an outer thread, and thus the inserting rod is wrapped with the threaded groove; finally, a press-fit threaded column abuts against the end of the outer side of the inserting rod, the inserting rod is subjected to press fit throughthe press-fit threaded column, and an inserting column is stably mounted; and meanwhile, if the inserting column and the abutting block need to be replaced, the driving plate, the outer threaded cylinder, the inserting rod and the abutting block are sequentially dismantled, and thus the inserting column and the abutting block are convenient to replace.

Description

technical field [0001] The invention relates to a compression type marine bearing. Background technique [0002] At present, in the field of marine accessories, the supporting function between the shaft and the bushing is also called bearing. This kind of supporting bearing is generally manufactured by molding method, and is mainly used in marine axial flow pumps, deep wells, etc. Pumps, etc., as a support for blades and pump blades. Existing support bearings generally include an external metal jacket and an internal rubber lining, but the connection between the rubber lining and the metal jacket is always not tight, and situations such as falling off and movement may occur, and the rubber lining of the rotating shaft and the bearing Excessive friction, loud noise, and long-term friction will lead to unstable connection between the shaft and the rubber lining. Contents of the invention [0003] In view of the deficiencies of the above-mentioned prior art, the problem to ...
