The utility model discloses a high wear-resisting oil-free scroll motor stationary disc matching structure, which comprises a matching stationary disc and a moving disc. The matching position of the stationary disc and the moving disc is provided with a ceramic wear-resisting layer, the contact surface of the stationary disc and the moving disc is provided with a wear-resisting sealing ring, and a group of air pressure automatic compensation holes are arranged in the high-pressure exhaust zone of the stationary disc and the wear-resist A ring groove is arranged on the outer surface of the mating part of the moving disc, and the wear-resistant seal ring is arranged in the ring groove. The wear-resistant seal ring is two-stage structure. The first section is located in the high-pressure exhaust zone of the static disc, and the second section is located outside the high-pressure exhaust zone. A partition zone is formed between the two sections. The air pressure automatic compensation hole set by the static disc enables the high-pressure gas to enter the ring groove of the high-pressure zone of the static disc Closely adhered to the moving disc, and this pressure makes the sealing ring continue to extend outward to compensate for wear. A ring groove is set on the stationary disc. The PTFE sealing ring is embedded in the ring groove, which plays an effective wear-resistant role. RSF die-casting process is used for the stationary disc and the rotating disc, which greatly reduces the pore and manufacturing costs. Then, surface ceramic treatment is used to increase wear resistance and impact resistance.

,尤其涉及一种高耐磨的无油涡旋机动静盘配合结构。
技术介绍
涡旋空气压缩机以其效率高、噪音低、体积小、高可靠性,有利于节能及保护环境等优点而广泛应用于工业、农业、交通运输等行业需要压缩空气的场合。涡旋空气压缩机主要靠静盘与动盘啮合形成压缩,运动中不产生磨损,因而寿命比活塞式、螺杆式压缩机更长,是风动机械理想动力源。在涡旋空气压缩机中,主要部件分别为静盘和动盘,静盘和动盘内设涡旋片,通常,由静盘和动盘彼此结合形成压缩腔,当动盘由在动力作用下,沿着一定圆周轨迹作平动时,动盘涡圈相对静盘涡圈移动,即由两者所形成的压缩腔移动并改变其容积,从而进行吸入、压缩、排放,完成压缩空气的过程。传统的无油涡旋机的动盘及静盘是采用低压铸造工艺,精加工后做硬质氧化处理,其缺点在于:硬质氧化处理后的动盘及静盘其变形量较大,尺寸影响严重。未提高动盘和静盘的耐磨度,严重影响零件设计对尺寸精度的要求。
