Abstract
(EN)

PROBLEM TO BE SOLVED: To allow alignment of at least three bearing sections to be easily performed in a rotary compressor pivotally supporting a rotation shaft by using the bearing sections, and further to suppress occurrence of tilting and runout of the rotation shaft.

SOLUTION: A compression mechanism section 12 includes: at least three cylinders 15a, 15b and 15c arranged in an axial direction of a rotation shaft 11; closing members 16, 17, 18 and 19 closing both ends of the cylinders 15a, 15b and 15c and forming cylinder chambers 20a, 20b and 20c inside the individual cylinders 15a, 15b and 15c; and rollers 22a, 22b and 22c eccentrically rotating inside the cylinder chambers 20a, 20b and 20c. The rotation shaft 11 is pivotally supported by bearing sections 16a, 18a and 19a provided to at least three of the closing members 16, 17, 18 and 19. When a clearance of each sliding portion among inner peripheral surfaces of the bearing sections 16a, 18a and 19a and an outer peripheral surface of the rotation shaft 11 is represented by "C" and each length among the inner peripheral surfaces of the bearing sections 16a, 18a and 19a and the outer peripheral surface of the rotation shaft 11 in the axial direction is represented by "L", a value of "C/L" of the bearing section 16a positioned closest to an electric motor section 10 is less than values of "C/L" of the other bearing sections 18a and 19b.

【課題】少なくとも三つの軸受部を用いて回転軸を軸支する回転式圧縮機において、それらの軸受部の調芯を容易に行えるようにし、しかも、回転軸の傾きや振れ回りの発生を抑制する。
【解決手段】圧縮機構部12は、回転軸11の軸方向に配列された少なくとも三つのシリンダ15a、15b、15cと、シリンダの両端を閉塞して各シリンダ内にシリンダ室20a、20b、20cを形成する閉塞部材16、17、18、19と、シリンダ室内で偏心回転するローラ22a、22b、22cとを有し、回転軸は閉塞部材の少なくとも三つに設けられた軸受部16a、18a、19aにより軸支され、軸受部の内周面と回転軸の外周面との間の摺動部分のクリアランスを“C”、軸受部の内周面と回転軸の外周面との間の軸方向の長さを“L”とした場合、電動機部10の最も近くに位置する軸受部16aの“C/L”の値は、他の軸受部18a、19bの“C/L”の値より小さい。
