[0022] In addition, as the rotation shaft 40 rotates, the inner gear 30 rotates and the rotational force of the inner gear 30 is transmitted to the outer gear 20 and the outer gear 20 also rotates, the upper and lower bearings 50, 60 that move relative to each other Friction occurs between the inner gear 30 and between the inner gear 30 and the outer gear 20, thereby increasing power consumption
In addition, wear between parts will shorten the life of parts, and it will also cause leakage of compressed gas

The present invention discloses a working oil supply structure of gear compressor. It includes the following several portions: closed container, its undersurface has lubricating oil; cylinder; outside gear which can be rotatably inserted into the interior of said cylinder; inside gear which is inserted into the interior of outside gear, can be contacted with said outside gear, then can be formed into several compression spaces; upper bearing and lower bearing which are respectively combined on two side faces of said cylinder and can be used for closing said compression space; rotary shaft which is passed through and inserted into the upper and lower bearings and combined with inside gear; and oil storage tank which is set between the described rotary shaft and inside gear combined with said rotary shaft.
Description
technical field [0001] The present invention relates to a gear compressor, in particular to a working oil supply structure of the gear compressor. Background technique [0002] In general, a compressor converts electrical energy into kinetic energy, and compresses refrigerant gas with the kinetic energy. The compressor is the core element of the refrigeration cycle system. According to the mechanism of compressing the refrigerant, it is divided into rotary compressors, scroll compressors, and reciprocating compressors. These compressors are used in refrigerators, air conditioners, display cabinets and other equipment. [0003] In the rotary compressor described above, the rotational force of the driving motor is transmitted to the rotating shaft to rotate the rotating shaft, and the eccentric portion provided on the side of the rotating shaft rotates in the compression space of the cylinder block as the rotating shaft rotates. While the eccentric portion rotates in the com...
