A bearing block adapted for use in a gear pump assembly. The bearing block includes a bearing surface configured to face one or more gears. The bearing block further includes a bearing block body formed with a recess. The bearing block further includes an insert located within the recess. The insert includes an insert body including an outer surface. The insert body has a tapered shape that tapers outwardly from the bearing surface. The insert further includes a plurality of ridges disposed on the outer surface. The plurality of ridges defines one or more grooves therebetween. The recess includes a tapered shape complementary to the tapered shape of the insert body, such that the insert body engages with the bearing block body.

A compressor and a refrigeration device are provided. The compressor has a crankshaft, a connecting structure, and an avoidance part arranged on the connecting structure and/or the crankshaft. The avoidance part is located at a position where the connecting structure is matched with the crankshaft. The avoidance part is configured to be suitable for avoiding at least one of the connecting structure and the crankshaft. A gap between the crankshaft and the connecting structure is increased through the arrangement of the avoidance part, so that the avoidance part can avoid the crankshaft when the crankshaft is obliquely deformed.
