Embodiment Construction
[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not constitute a conflict with each other.
[0026] The sleeve parts of hydraulic components are generally "short tube"-shaped parts, and their outer circle generally has an interference or transition fit with the base parts that fix it. Circular clearance fit. The inner hole bears the radial force from the shaft parts, and at the same time slides and rotates relative to the outer circle of the shaft parts. Therefore, the sleeve parts are...

The invention discloses a sleeve-type part for a water hydraulic component. The sleeve-type part is in a hollow cylinder structure, material of the cylinder is bone material and is produced by machining, and a matched sleeve can added on the periphery of the cylinder to form a higher cylinder structure. The invention further discloses a sleeve-type part for a water hydraulic component. The sleeve-type part is in a hollow cylinder structure, and is characterized in that the materials of the sleeve-type part are composite materials mixed by bone powders and polymer material. The invention further discloses a production method and application thereof. The sleeve-type parts for the water hydraulic components are utilized for bearing compressing force, are made of natural bone materials, and accordingly have good water lubricity and moderate impact resistance owing to tiny cavities in microstructures of bones and viscoelastic property of cell structures.
Description
technical field [0001] The invention relates to a water hydraulic component, in particular to a sleeve part used in a water hydraulic component and a manufacturing method and application thereof. Background technique [0002] Sea (fresh) water hydraulic technology is a new development in fluid power technology to meet the needs of human beings entering the ocean. The concentrated embodiment of water hydraulic technology is various water hydraulic components, such as slide valves, pumps, plungers, sliding bearings, etc. Due to the harsh environment in the water body, such as the erosion of marine organisms in the marine environment, abrasive wear of tiny particles in the water, etc., the most common problems of the friction pairs of these water hydraulic components when working in sea (fresh) water are corrosion and wear. The most common form of friction pair structure is "shaft (such as pin, plunger, valve core) and sleeve (such as bearing sleeve, plunger sleeve and slide v...
