Patent number: 9528504Abstract: The outer periphery of the outer part of a substrate is a chamfer, and the outer part of the substrate is covered by a resin film layer. The thickness of the resin film layer at the chamfer is thicker than the locations radially further inwards from said chamfer. The surface of the resin film layer on the outer peripheral edge of the outer part is coplanar with the surface of the resin film layer further inwards. These locations act as the sliding surface (the surface of the swash plate) that slides on a shoe, and compared with conventional techniques, because the resin film layer in the outer peripheral edge is thick, attrition of the portion being pressed against the shoe is suppressed. For that reason, the outer peripheral edge of the substrate and the vicinity thereof are prevented from being exposed, and seizure of the swash plate can be prevented.Type: GrantFiled: March 25, 2013Date of Patent: December 27, 2016Assignee: TAIHO KOGYO CO., LTD.Inventors: Masato Shibata, Kyohei Yamane, Shingo Goto

Patent number: 9316298Abstract: A swash plate type compressor is arranged with a plurality of semispherical shoes and a disc shaped swash plate. A resin coating is formed on a surface and a rear surface (sliding surface) of the swash plate which slides with the shoe. The resin coating includes a structure whereby multiple hexagonal cylinder bodies are fabricated on a surface of a substrate and an end surface of each cylinder body forms a sliding surface which slides with the shoe. In addition, a honeycomb shaped groove is formed at an adjacent position of each cylinder body forming a storage part of a lubricant O and a container part for foreign objects. The swash plate can be provided with excellent wear resistance, seizure resistance and lubrication retention.Type: GrantFiled: October 30, 2012Date of Patent: April 19, 2016Assignee: TAIHO KOGYO CO., LTD.Inventors: Kyohei Yamane, Shingo Goto

Patent number: 9206890Abstract: This swash plate comprises a resin film layer formed on the front surface and the rear surface, and said resin film layer serves as the sliding surface which slides on a shoe. The inner periphery of the resin film layer is a tilted surface which a lubricant can easily cross over. In other words, angle ?1 is 10° or less and angle ?2 of the rising part is set to 20° or less, and when the lubricant is supplied from the inner periphery side of the swash plate, said lubricant easily crosses over said inner periphery which is a tilted surface, and is quickly supplied to the surface (the sliding surface) outside of said inner periphery. Because the lubricant is quickly supplied to the front surface and the rear surface (the sliding surface) of the swash plate, seizure of the swash plate can be prevented.Type: GrantFiled: March 25, 2013Date of Patent: December 8, 2015Assignee: TAIHO KOGYO CO., LTD.Inventors: Masato Shibata, Kyohei Yamane, Shingo Goto

Patent number: 9074628Abstract: A swash plate type compressor is arranged with a plurality of semispherical shoes and a disc shaped swash plate. A resin coating having a honeycomb structure is formed on a surface and a rear surface (sliding surface) of the swatch plate which slides with the shoe. An edge part (top end) of each of the multiple cylinder bodies which forms the resin coating layer are at the same plane and forms a sliding surface which slides with the shoe. In addition, an interior space of each cylinder body forms a storage part of a lubricant and a container part for foreign objects. The swash plate can be provided with excellent wear resistance, seizure resistance and lubrication retention.Type: GrantFiled: October 30, 2012Date of Patent: July 7, 2015Assignee: TAIHO KOGYO CO., LTD.Inventors: Kyohei Yamane, Shingo Goto
