Description

Technical Field

[0001] The invention relates to an assembly structure of a segmented adjustable marine bearing sleeve. Background Art

[0002] Marine bearing sleeves are components that support the shaft for rotation. They are generally manufactured by molding and are mainly used in marine axial flow pumps, deep well pumps, etc. as supports for blades and pump blades. Existing marine bearing sleeves generally include an outer sleeve and an inner sleeve. The outer sleeve and the inner sleeve are generally installed as a whole by vulcanization or bonding. The inner sleeve of this structure is generally fixedly installed inside the outer sleeve. Therefore, the length of the inner sleeve cannot be extended. When a longer rotating shaft needs to be assembled, it is necessary to replace the outer sleeve and the inner sleeve of other sizes. For this reason, existing The marine bearing sleeve of the structure is not flexible to use; in addition, after the marine bearing sleeve of the traditional structure has been used for a period of time, the rotating shaft is prone to wear on the internal sleeve, so that the internal sleeve needs to be repaired and replaced. Once the internal sleeve is partially worn, the entire internal sleeve will be scrapped and needs to be replaced as a whole, which makes the overall use cost high. In addition, it will be very difficult to disassemble and repair the internal sleeve, and it will take a long time to separate the internal sleeve from the external sleeve, which makes the disassembly and maintenance work inconvenient, and at the same time, it is necessary to improve the flexibility and convenience of the structure.
