Compressor

The compressor comprises a bearing assembly and a crankshaft, the bearing assembly is installed in a shell, the bearing assembly comprises at least one bearing, and the bearing is provided with a bearing hole; the crankshaft is provided with a shaft section mounted in the bearing hole, and the crankshaft is rotatably arranged relative to the bearing; the antifriction coating is arranged on at least part of the inner wall face of at least one bearing hole, so that at least one antifriction coating is arranged between the contact faces of the bearing and the crankshaft, the antifriction coating can reduce the friction coefficient between the contact faces of the crankshaft and the bearing, and the purposes of reducing input force and improving performance are achieved. On the premise of not changing the part structure and material of the compressor, the purposes of improving the abrasion performance of a crankshaft and a bearing friction pair, improving the lubricating effect of a crankshaft and bearing matchin
