▎ 摘　　要

NOVELTY - The surface self-lubricating shoe has shoe main portion (1) that is provided with a central oil chamber at the bottom for oil storage. The shoe main portion is provided with a ball socket (3) for matching with the ball head of the plunger. One end of the ball socket near the bottom of the shoe portion is provided with a damping hole (4). The damping hole is communicated with the ball socket and central oil chamber (5). The surface of the end of the shoe main portion for contacting the swash plate is provided with a micro-texture (6). The micro-texture is distributed circumferentially along the outer side of the central oil chamber, and located between the central oil chamber and the swash plate. The sliding shoe main portion is made of stainless steel. The self-lubricating material is graphene, molybdenum disulfide or PTFE solid lubricating material. The solid lubricating material is used for uniform mixing with the binder. USE - Surface self-lubricating sliding shoe for sliding boot pair (claimed) for swash plate axial piston hydraulic pump such as power component of hydraulic transmission system used in construction machinery, aerospace, ship machinery and construction equipment. ADVANTAGE - The micro-texture is provided on the shoe main portion so that the oil enters the central oil chamber from the plunger cavity through the damping hole to be stored in the micro-texture, and the oil in the micro-texture makes the bottom surface of the portion of the shoe seal with oil. The belt is formed with a lubricating oil film in a short time, which increases the thickness of the oil film, improves the supporting force of the oil film, reduces the leakage, improves the lubrication characteristics of the shoe pair, and reduces the friction and wear on the surface of the swash plate and the surface of the shoe and extends the life of the shoe and swash plate. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a preparation method of surface self-lubricating sliding shoe; and liding boot pair. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the sliding shoe. 1Sliding shoe main portion 3Ball socket 4Damping hole 5Central oil chamber 6Micro-texture
