Kind Code:
A1
Abstract:
A rope sheave (10) comprises: a rotatably supported rotating shaft (22); a rope support member (8) which has a rope support groove annularly provided in the outer periphery thereof, has an inner peripheral surface provided at the center thereof and forming a first hole, and is disposed so that the rotating shaft is located in the first hole; a contact member (20) which protrudes in the diameter direction of the rotating shaft and which is provided to the rotating shaft in the centerline direction of the rotating shaft so as to be capable of being in contact with the rope support member; a mounting member (30) which has a second hole for allowing the rotating shaft to be fitted therein, has an outer peripheral surface engaged with the inner peripheral surface, and is provided while a gap is formed between the mounting member (30) and the contact member; and a pressing member (26) which is removably mounted to the rotating shaft or the contact member and which presses the mounting member in the centerline direction toward the contact member. The center of the annular rope support groove and the center of the first hole are located on the same straight line, the center of the outer peripheral surface and the center of the second hole are located on the same straight line, and the outer peripheral surface and the inner peripheral surface are tapered so that the diameters of the outer peripheral surface and the inner peripheral surface decrease in the direction toward the contact member.
