SEAT ANGLE ADJUSTER AND OIL GATHERING ELEMENT

摘要

A seat angle adjuster and an oil gathering element. The oil gathering element (1) is fixedly connected to one component in a friction pair (2) of the seat angle adjuster. The oil gathering element (1) has an end surface (11) facing the other component in the friction pair (2). A boss (12) is disposed at each of two ends of the end surface (11), so that an oil gathering gap (13) is formed on the middle section of the end surface (11). A side surface of each boss (12) is an oil guide surface (121), and the side surfaces are disposed close to the middle of the oil gathering gap (13) gradually from outside to inside. With the oil gathering element (1), lubricant oil in a friction pair (2) can be again gathered to friction surfaces to reduce rate of wear. During movement, outer sides of the oil guide surface (121) of the boss (12) are firstly abutted against an end wall of the other component, so that the lubricant oil ground by the friction pair (2) to two ends of the other component is obstructed, the obstructed lubricant oil further flows along the oil guide surface (121) of the boss (12) to the oil gathering gap (13) on the middle section of the end surface (11) of the oil gathering element (1), and then the friction surfaces are lubricated. When the friction pair (2) rotates at a high speed, the oil gathering gap (13) of the oil gathering element (1) serves as a dynamic oil way, so that the lubricant oil is constantly gathered to be between the friction surfaces.
