Self-lubricating device for molded line back surface of movable disc of scroll compressor

The invention discloses a scroll compressor movable disc molded line back self-lubricating device, which comprises a bearing pad arranged between a movable scroll disc molded line back and a bearing seat, and is characterized in that a lubricating friction backing ring is arranged between the movable scroll disc molded line back and the bearing pad; the face, located on the bearing pad, of the lubricating friction backing ring is made of self-lubricating materials, and the lubricating friction backing ring and the bearing pad do planar motion mutually. Compared with the prior art, the problems that friction force between the back face of the movable scroll plate molded line of an existing compressor and a bearing pad is large, abrasion is prone to occurring, noise is large, and the compression effect is affected can be solved. 本发明公开了一种涡旋压缩机动盘型线背面自润滑装置，它包括动涡旋盘型线背面与轴承座之间设置的轴承垫，其特征在于：所述动涡旋盘型线背面与所述轴承垫之间设有润滑摩擦垫环，所述润滑摩擦垫环于所述轴承垫的一面为自润滑材料，所述润滑摩擦垫环与所述轴承垫相互做平面运动。本发明与现有技术相比，可以解决现有压缩机的动涡旋盘型线背面与轴承垫之间摩擦力大易磨损，且噪声大，影响压缩效果的问题
