Abstract
Provided is a sliding component capable of reducing the frictional resistance of a sliding surface entailing eccentric rotation. An annular sliding component has a sliding surface relatively sliding with eccentric rotation. A plurality of grooves open to a fluid space on the inner diameter side are circumferentially provided in the sliding surface. A side wall surface of the groove is configured by a wall surface continuous in a circular arc shape in a plan view.
Claims12
An eccentric sliding assembly in accordance with the present invention comprising:
- a first sliding component formed in an annular shape and having a sliding surface, wherein
- a second sliding component having a sliding surface;
- and
- an eccentric driving device configured to cause the sliding surface of the first slide component to slide relative to the sliding surface of the second sliding surface such that a center of the first sliding component imaginarily draws a circle which is eccentric with respect to a center of the second sliding component while keeping non-rotation state of the first sliding component with respect to the center of the first sliding component in a plan view,
- the sliding surface of at least one of the first sliding component and the second sliding component is provided with a plurality of grooves each of which is open to a fluid space on at least one of an inner diameter side and an outer diameter side and which are arranged in a circumferential direction, and
- a side wall surface of each of the grooves is configured by a wall surface continuous in a circular arc shape in a plan view.
