Problems solved by technology

[0002] The friction between the stern shaft and the jacket of the existing ship is made of alloy material, which is expensive and wears fast, and with the wear of the alloy material, the vibration of the stern shaft intensifies, causing the ship to run unstable. The vibration of the shaft intensifies, causing the water gland to break and causing water leakage in the engine room. Based on the above reasons, this alloy material generally only needs to be replaced in 1-2 years. can also increase

Embodiment Construction

[0011] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0012] Such as figure 1 As shown, a shaft sleeve structure includes a hollow cylindrical body 1, an oil hole 2 is arranged on the cylindrical body 1, an oil groove 3 is arranged on the inner wall of the cylindrical body 1 along the circumferential direction, and the cylindrical body 1 The outer surface of the shape main body 1 is provided with a notch 4, which is convenient for installation and disassembly.

[0013] Further, in the present invention, it is preferable that the shape of the oil groove is rhombus, so as to keep the injected lubricating oil circulating on the inner wall of the cylindrical body 1, so as to impro...

Abstract

The invention relates to a shaft sleeve structure which comprises a hollow cylindrical body. An oil orifice is arranged on the cylindrical body, oil grooves are disposed on the inner wall of the cylindrical body along a peripheral direction, and a gap is arranged on the external surface of the cylindrical body. The shaft sleeve structure is advantageous in that: wear-resistance property of a shaft sleeve is greatly improved and simultaneously energy is saved, and deformation generated by different temperature differences can be farthest reduced, thereby preventing difficulties brought by the installation and use of the products, saving production cost and improving efficacy.

Description

technical field [0001] The invention relates to a matching device of a mechanical shaft, in particular to a shaft sleeve structure. Background technique [0002] The friction between the stern shaft and the jacket of the existing ship is made of alloy material, which is expensive and wears fast, and with the wear of the alloy material, the vibration of the stern shaft intensifies, causing the ship to run unstable. The vibration of the shaft intensifies, causing the water gland to break and causing water leakage in the engine room. Based on the above reasons, this alloy material generally only needs to be replaced in 1-2 years. can also increase. Contents of the invention [0003] In order to overcome the above defects, the technical problem to be solved by the present invention is to provide a shaft sleeve structure that can not only reduce frictional resistance, but also be cheap and prolong the service life. [0004] The technical solution adopted in the present invent...
