Problems solved by technology
The outer peripheral surface of the crankshaft of the horizontal compressor can be provided with a spiral oil groove. The oil inlet end of the spiral oil groove is supplied by radial oil holes, and the oil outlet end is directly connected to the exhaust pressure. However, under the action of the exhaust pressure, the spiral oil groove It is difficult for the lubricating oil inside to reach the oil outlet, so that the entire supporting surface of the main bearing cannot be lubricated, the main bearing and the crankshaft wear heavily, and the service life is short

Abstract
The invention discloses a horizontal compressor. The horizontal compressor comprises a shell, a driving motor and a compression mechanism, wherein the driving motor is arranged in the shell; the compression mechanism is arranged in the shell and comprises a crankshaft and a main bearing, a central oil hole and a main shaft section side-part oil hole communicated with the central oil hole are formed in the crankshaft, a spiral oil trough is formed in the outer peripheral surface of the crankshaft or the inner peripheral surface of the main bearing, an oil storage trough and an oil leakage trough are formed in the main bearing, one end of the spiral oil trough is communicated with the oil storage trough, the other end of the spiral oil trough is communicated with the oil leakage trough, lubricating oil in the spiral oil trough flows in the spiral oil trough according to a direction from the oil storage trough to the oil leakage trough when the crankshaft rotates, the oil storage trough is communicated with the main shaft section side-part oil hole and is provided with a gap part suitable for being communicated with discharge pressure, and the oil leakage trough is used for conveying the lubricating oil from the spiral oil trough to an oil tank in the shell. According to the horizontal compressor, a lubricating effect of the main bearing to the crankshaft can be improved, and the service lives of the main bearing and the crankshaft can be prolonged.
Description
technical field [0001] The invention relates to the field of rotary compressors, in particular to a horizontal compressor. Background technique [0002] The general structure of the horizontal compressor and the vertical compressor is basically the same, the difference is that the crankshaft of the horizontal compressor is along the horizontal direction, while the crankshaft of the vertical compressor is along the vertical direction. The outer peripheral surface of the crankshaft of the horizontal compressor can be provided with a spiral oil groove. The oil inlet end of the spiral oil groove is supplied by radial oil holes, and the oil outlet end is directly connected to the exhaust pressure. However, under the action of the exhaust pressure, the spiral oil groove It is difficult for the lubricating oil inside to reach the oil outlet, so that the entire supporting surface of the main bearing cannot be lubricated, the main bearing and the crankshaft wear heavily, and the serv...
