Abstract

The invention provides a crankshaft, a scroll compressor and a vehicle. The crankshaft comprises a first rotating shaft, a second rotating shaft, a first shaft shoulder, a second shaft shoulder and anoil filling passage. The axis of the first rotating shaft and the axis of the second rotating shaft are parallel to each other. The first shaft shoulder and the first rotating shaft are coaxially arranged, and the second shaft shoulder and the second rotating shaft are coaxially arranged. The oil filling passage is arranged in the first rotating shaft, the first shaft shoulder and the second shaft shoulder. A first opening of the oil filling passage is formed in the first rotating shaft, a second opening of the oil filling passage is formed in the second shaft shoulder, and the second rotating shaft is a solid shaft. By the adoption of the technical scheme, the problems that an oil filling passage penetrating through a crankshaft is arranged in the crankshaft in the prior art, so that thestructural strength of the crankshaft is insufficient, damage to the crankshaft is caused easily and the normal operation of a scroll fluid machine is influenced are solved.

Description

technical field [0001] The invention relates to the field of air compressors, in particular to a crankshaft, a scroll compressor and a vehicle. Background technique [0002] In the oil-free scroll air compressor, there is an anti-rotation structure, which includes a drive plate installed on the back of the orbiting scroll, and a bell crank assembly composed of a bell crank bearing and a bearing cover plate. Wherein, the bearing on one side of the crank throw assembly is assembled in the bearing housing hole of the drive plate, and the two are connected by cover plate bolts. The bearing on the other side of the crank throw assembly is assembled in the bearing seat hole of the bracket and connected by bolts of the bearing end cover. The drive plate runs under the drive of the drive shaft, thereby preventing the rotating scroll from rotating. Because it is an oil-free air compressor, the pump body does not need oil lubrication, but there are paired bearings in the anti-rotati...
