Description
図1は、スラストベアリングの断面図である。図1に示すように、スラストベアリングは、複数の球状の転動体1と、一対の環状のスラスト受座2,2と、スラスト受座2,2間に介装される環状の保持体3とを有する。複数の転動体1は、保持体3によって円周方向に等間隔に保持されている。一対のスラスト受座2,2の互いに対向する面には、それぞれ円環状の軌道面4が形成されており、この軌道面4に沿って転動体1が転がり摺動するようになっている。
図7は、試験装置の簡略図である。この試験装置は、スラストベアリング10の一方(図の上側)のスラスト受座2を保持する上治具11と、他方(図の下側)のスラスト受座2を保持する下治具12を備える。上治具11を下治具12に対し回転させることにより、転動体1を軌道面4に沿って転がり摺動させることができる。このとき転動体1と軌道面4の間に生じる転がり摩擦係数を測定する。また、試験装置は、転動体1にアキシャル方向の荷重を付与するためのエアシリンダ13を備えている。
まず、図8の(a)〜(e)に示す各種ベアリングにおいて、一対のスラスト受座2,2を、試験装置の上治具11と下治具12に固定すると共に、エアシリンダ13によって転動体1にアキシャル方向の荷重を付与する。次に、上治具11を下治具12に対し回転させることにより、転動体1を軌道面4に沿って転動させる。転がり摩擦の測定前に、回転速度2.4m/s(約59πrad/s)で30分間回転させ、転動体1の温度を定常化させる。その後、回転速度を段階的に低下させながら、転動体1と軌道面4の間に生じる転がり摩擦係数を測定する。
