Description
- The present invention relates to a hermetic compressor wherein the lubrication performance of the movable members therein is improved.
- In the reciprocating hermetic compressors used in refrigerators, the journal bearings wherein the crankshaft operates and the other movable members are lubricated with the oil disposed in the compressor casing. In compressors, lubrication provides friction losses of the movable members to be decreased, abrasion to be prevented and heat resulting from friction to be removed by decreasing the temperature of the compressor members. In the compressor lubrication system, the oil at the base of the casing is sucked to be delivered to the bearings and compressor members that are to be lubricated. Generally, the centrifugal force that acts on the oil as a result of the rotation of the crankshaft is utilized for delivering the oil at the base of the casing to the bearings. In variable capacity compressors used in refrigerators, the refrigeration capacity that changes depending on the operating conditions is provided by changing the compressor rotational speed. Since the compressor motor operates at low speed in cases where low capacity is to be met, abrasion may occur in bearings operating in hydrodynamic lubrication conditions. In order to deliver the oil required in cases where the compressor motor operates at low speed, a cylindrical oil sucking member having helical oil transportation grooves is concentrically disposed at the lower end of the crankshaft immersed into oil in the rotation axis of the crankshaft. In the casing of the compressor, oil level in the vicinity of the lower end of the crankshaft decreases by the effect of the rotation of the crankshaft and for this reason, the lower end of the crankshaft loses contact with the oil from time to time. If the oil level at the crankshaft level decreases during the operation of the hermetic compressor, sufficient oil cannot be delivered to the movable members and bearings on the motor, abrasion problems occur.
