A horizontal scroll compressor

Abstract

The invention provides a horizontal vortex compressor. The horizontal vortex compressor comprises a front shell, a back shell, a hollow shell, a motor, an eccentric crankshaft, an oil pump rotor, a through oil pump shaft, a compressed vortex disc, a main bearing and an auxiliary bearing; the back shell corresponds to the front shell, an oil pump stator and a bearing support are integrated with the back shell; the hollow shell is connected with the front shell and the back shell; the eccentric crankshaft is connected to a rotor of the motor so as to transmit rotating force and comprises a long shaft portion, an eccentric pin hole is formed in the first end of the long shaft portion, an eccentric pin is arranged at the second end of the long shaft portion, and an oil hole is formed in the eccentric crankshaft and penetrates through the eccentric crankshaft in the length direction of the eccentric crankshaft; the oil pump rotor is matched with the oil pump stator to form an oil pump; the two ends of the through oil pump shaft are sleeved with the oil pump rotor and the eccentric pin hole of the long shaft portion respectively; the motor, the oil pump and the auxiliary bearing are all arranged on the low-pressure side of the horizontal vortex compressor for an automobile. According to the horizontal vortex compressor, the requirement that the size of the compressor is small can be met, and the lubricating effect can be enhanced.

Description

technical field [0001] The invention relates to a compressor, in particular to a horizontal scroll compressor in which an oil pump, an auxiliary bearing and a rear casing are integrated. Background technique [0002] The existing horizontal electric scroll compressors for new energy vehicles use the exhaust side to separate the lubricating oil, and then throttle and reduce the pressure to send it back to the low-pressure side bearing to supply oil, and some do not use oil-air pumps for oil-air lubrication. of. Adopting the method of throttling and lowering the pressure after oil separation on the exhaust side, the throttling structure is prone to clogging, resulting in failure of lubrication and damage to the compressor; the method of oil-air lubrication is better when the compressor power is small, but in the power When it is larger, the lubrication effect will be insufficient, which will cause lubrication failure. Contents of the invention [0003] Aiming at the defect...
