To detect oil leakage quantitatively before oil leaked from a bearing of an elevator hoisting machine 1 adheres to a brake disk 11.SOLUTION: An elevator hoisting machine 1 includes a pair of bearings fixed to a bearing stand 5, a rotation shaft 4 rotatably supported by the pair of bearings; a sheave 3 fixed about a shaft of the rotation shaft 4 so as to be rotated integrally with the rotation shaft 4; a brake disk 11 fixed to one side in the axial direction of the sheave 3; and a friction measurement part 13 measuring the friction force by making a friction measurement member contact to a first contact surface when the sheave 3 is rotated while setting one side surface in the axial direction of the sheave 3 with the exception of a portion where the brake disk 11 is fixed to the sheave 3 or an exposed surface of the rotation shaft 4 between one side surface in the axial direction of the sheave 3 and the pair of bearings as a first contact surface.SELECTED DRAWING: Figure 1
【課題】エレベータ用巻上機1の軸受から流出した油分がブレーキディスク11に付着する前に油分漏れを定量的に検知する。【解決手段】本開示に係るエレベータ用巻上機1は、軸受台5に固定された一対の軸受と、一対の軸受に回転可能に支持された回転軸4と、回転軸4と一体に回転するように回転軸4の軸周りに固定された綱車3と、綱車3の軸方向の一方側に固定されたブレーキディスク11と、ブレーキディスク11が綱車3に固定された部分を除く綱車3の軸方向の一方側の側面、または綱車3の軸方向の一方側の側面と一対の軸受との間の回転軸4の露出面を第一接触面として、綱車3の回転時に摩擦測定部材を第一接触面に接触させて摩擦力を測定する摩擦測定部13とを備える。【選択図】図1
