Description
C1×0.025/{(T2−T1)×α}≦L≦C1×0.20/{(T2−T1)×α}
の範囲内とすることを特徴とする。
C1×0.025/{(T2−T1)×α}≦L≦C1×0.20/{(T2−T1)×α} ・・・式(1)
の範囲内で設定すればよいことになる。換言すると、上記した式(1)の範囲内において樹脂摺動層3の厚さLを設定した場合には、常用運転時の軸受隙間C1に対し、始動時の軸受隙間C2を2.5%以上から20%以下の範囲内で相対的に大きくすることができる。これによれば、常用運転時には、クランク軸4の軸心の振れによる冷凍機用圧縮機の圧縮効率の低下を防止するため、軸受隙間C1を狭くしながらも、始動時には、常用運転時に対して軸受隙間C2が2.5%以上から20%以下の範囲内で大きくなるので、樹脂摺動層3の摺動面の全域とクランク軸4表面との直接の接触を防ぐことが可能となる。
