Abstract
To provide sliding components capable of suppressing dynamic pressure generation mechanisms from being deformed and damaged due to wear of sliding surfaces. In a pair of sliding components which is disposed at a relatively rotating position of a rotary machine, has a plurality of dynamic pressure generation mechanisms formed in a sliding surface of the sliding component by recessed portions, and is formed in an annular shape to seal a sealed fluid by sliding the sliding surfaces of the sliding components. A surface region in the periphery of the recessed portions of the sliding component is formed to be separated from an opposite region of the sliding component.
Claims9
A pair of sliding components which is constituted by a first sliding component and a second sliding component and disposed at a relatively rotating position of a rotary machine, comprising a plurality of dynamic pressure generation mechanisms formed by recessed portions that are provided in a sliding surface of the first sliding component, the first sliding component and the second sliding component being formed in an annular shape to seal a sealed fluid by sliding a land portion of the sliding surface of the first sliding component and a land portion of a sliding surface of the second sliding component to each other,
- wherein a surface region in a periphery of the recessed portions of the first sliding component is formed to be separated from an opposite surface region of the second sliding component opposed to the surface region of the first sliding component,
- wherein the land portions of the first sliding component and the second sliding component each has an annular shape,
- the recessed portion is a recessed groove of which one end is closed, and
- the one end of the recessed groove extends to a region in which the land portions face each other,
- wherein adjoining two of the recessed portions are connected to each other by a fine recess, and
- wherein a boundary portion of the fine recess on a side of the land portion of the first sliding component is formed to be disposed on a waveform when viewed from an axial direction.
