Problems solved by technology

Therefore, the counterweight 22 does not have enough inertial force, that is, the reciprocating inertial force of the piston 20 cannot be sufficiently offset, thereby increasing the vibration of the hermetic compressor

Abstract

Outer circumferential shape of a balance weight is composed so that the distance between the outer circumference of the balance weight and the piston is substantially constant in the closely approaching interval of the balance weight and piston.

Description

technical field [0001] The present invention relates to a hermetic compressor used in refrigeration cycles such as refrigerators, air conditioners and freezers. Background technique [0002] Recently, there has been a strong demand for hermetic compressors in domestic refrigerators and freezers to be smaller in size, lower in noise and vibration. In this context, the refrigerant needs to be converted to a hydrocarbon refrigerant, such as a natural refrigerant of R600a, which has a lower global warming coefficient expressed as an ozone depletion coefficient. Also, in order to maintain the balance of the piston which is the main source of vibration, the method of using a counterweight is an effective technique for reducing vibration. [0003] Heretofore, with such a hermetic compressor using a counterweight, it has been attempted to adjust the unbalanced force of the compressor mechanism by installing a counterweight having an approximately arc-shaped profile on the crankshaf...
