Description

本発明に係るロータリー圧縮機は、密閉容器内に圧縮機構部とこれを駆動する電動機部を有し、圧縮機構部は、複数の偏心部を有するクランク軸と、クランク軸の各偏心部に対応させて配置された複数のシリンダーと、複数のシリンダー間に配置されてこれらシリンダーにより挟持される仕切板と、これらシリンダー内に位置するように配置されてクランク軸の各偏心部がそれぞれ挿入された複数のローラーと、クランク軸が挿入されて、シリンダーと仕切板を積み重ねたものの両端に配置された主軸受及び副軸受と、シリンダーと主軸受と仕切板とローラーとによって囲まれる空間、及びシリンダーと副軸受と仕切板とローラーとによって囲まれる空間を、それぞれ圧縮室と吸入室の２つの空間に仕切る複数のベーンとを備え、仕切板に熱処理を施し、仕切板の硬度が主軸受及び副軸受の硬度よりも高くなるように硬度差をもたせたものである。 Rotary compressor according to the present invention has a motor unit for driving the compression mechanism unit into tight closed container, a compression mechanism unit includes a crank shaft having a plurality of eccentric portions, each eccentric portion of the crankshaft A plurality of cylinders arranged in correspondence with each other, a partition plate arranged between the cylinders and sandwiched by these cylinders, and each eccentric part of the crankshaft arranged so as to be positioned in these cylinders are respectively inserted. A plurality of rollers, a main bearing and a secondary bearing arranged at both ends of a stack of a cylinder and a partition plate into which a crankshaft is inserted, a space surrounded by the cylinder, the main bearing, the partition plate, and the roller, and the cylinder and a space surrounded by the auxiliary bearing and the partition plate and the roller, and a plurality of vanes for partitioning into two spaces each compression chamber and the suction chamber, heat specifications Setsuban Subjected to physical, in which the hardness of the partition plate remembering hardness difference to be higher than the hardness of the main bearing and the sub-bearing.

Claims
