Claims

[Scope of utility model registration request]

A fixed scroll fixed to the frame, an orbiting scroll meshed with the fixed scroll, a main drive crankshaft attached to the frame to drive the orbiting scroll, and a shaft connected to the orbiting scroll and the frame through bearings around the main drive crankshaft. At least three driven crankshafts are installed at regular intervals to prevent the rotation of the orbiting scroll and to transmit the scrat load applied to the scroll to the frame, and the fixed scroll and the orbiting scroll are arranged on the back side. An air-cooled oil-less scroll compressor comprising cooling fins, the driven crankshaft having a balance weight and a trim weight, and a plurality of bearings of the driven crankshaft arranged in parallel.
