The invention provides an elevator hoist and an oil leakage detection device. Oil leakage is quantitatively detected before oil flowing out of a bearing of an elevator hoist (1) adheres to a brake disc (11). This elevator hoist (1) is provided with: a pair of bearings fixed to a bearing block (5); a rotating shaft (4) rotatably supported by the pair of bearings; a sheave (3) fixed around the axis of the rotating shaft (4) so as to rotate integrally with the rotating shaft (4); a brake disc (11) fixed to one side of the sheave (3) in the axial direction; and a friction measurement unit (13) that measures friction force by bringing a friction measurement member into contact with a first contact surface when the sheave (3) rotates, the first contact surface being a side surface on one side in the axial direction of the sheave (3) excluding a portion to which the brake disc (11) is fixed, or an exposed surface of the rotating shaft (4) between the pair of bearings, the side surface on one side in the axial direction of the sheave (3), and the first contact surface being a first contact surface.
本发明提供电梯用曳引机以及油分泄漏检测装置。在从电梯用曳引机(1)的轴承流出的油分附着于制动盘(11)之前定量地检测油分泄漏。本发明的电梯用曳引机(1)具备:一对轴承,其固定于轴承座(5);旋转轴(4),其被一对轴承支承为能够旋转;绳轮(3),其以与旋转轴(4)一体地旋转的方式绕旋转轴(4)的轴线被固定;制动盘(11),其固定于绳轮(3)的轴向上的一侧;以及摩擦测定部(13),其以除了在绳轮(3)上固定制动盘(11)的部分外的绳轮(3)的轴向上的一侧的侧面、或绳轮(3)的轴向上的一侧的侧面与一对轴承之间的旋转轴(4)的露出面作为第一接触面,在绳轮(3)旋转时使摩擦测定部件与第一接触面接触来测定摩擦力。
