Problems solved by technology

However, when the compressor is stopped and the lubricating oil in the friction pair of the eccentric part of the crankshaft evaporates, when the compressor is powered on again, the friction pair of the eccentric part of the crankshaft will be in a dry friction state for a period of time, which will greatly damage the surface of the eccentric part of the crankshaft and cause wear

Abstract

The invention discloses a crankshaft and a compressor which are used in the field of compressors. The crankshaft comprises a main shaft part, fan blades and an eccentric part; the main shaft part is provided with a main shaft part oil way, the fan blades are connected with the main shaft part, the fan blades are provided with oil storage structures and balance parts; the eccentric part is deviatedfrom the axis of the main shaft part and is connected with the fan blades, and the eccentric part is provided with an eccentric part oil way; wherein the oil storage structures are communicated withthe main shaft part oil way and the eccentric part oil way to form an oil supply passage; the compressor comprises the crankshaft, the oil storage structures are arranged on the fan blades, the lubricating oil can be stored in the oil storage structures, when the compressor operates, the lubricating oil in the oil storage structures can quickly flow under the action of inertia force, and the friction pair of the eccentric part of the crankshaft is directly lubricated. The crankshaft and the compressor has the capability of rapidly lubricating the friction pair of the crankshaft eccentric partduring the initial operation stage of the compressor, the lubricating condition of the crankshaft eccentric part friction pair at the starting stage of the compressor is greatly improved, and the service life of the compressor is prolonged.

Description

technical field [0001] The invention is used in the field of compressors, and in particular relates to a crankshaft and a compressor. Background technique [0002] As we all know, the driving mechanism of reciprocating piston compressor is motor-crankshaft-connecting rod-piston pin-piston, wherein the main shaft part of the crankshaft is assembled with the motor rotor to provide power input, and the eccentric part of the crankshaft is assembled with the large hole of the connecting rod to output power. Because of dynamic balance and structural design, the length of the eccentric part of the crankshaft is usually very short, which ensures the compact design and good dynamic balance effect of the compressor, but the side effect is that the too short eccentric part length increases the force on the eccentric part of the crankshaft sharply, Bad for the durability of the crankshaft. Therefore, the compressor needs sufficient oil pumping capacity to ensure that the friction pairs...
