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

The utility model discloses a self-lubricating device for the back surface of a movable scroll plate molded line of a scroll compressor, which comprises a bearing pad arranged between the back surface of the movable scroll plate molded line and a bearing seat, and is characterized in that a lubricating friction backing ring is arranged between the back surface of the movable scroll plate molded line and the bearing pad; the face, on the bearing pad, of the lubricating friction backing ring is made of self-lubricating materials. Compared with the prior art, the utility model can solve the problems that the friction force between the back surface of the movable scroll plate molded line of the existing compressor and the bearing pad is large, the abrasion is easy, the noise is large, and the compression effect is influenced. 本实用新型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。本实用新型与现有技术相比，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。
