Embodiment Construction

[0056] Hereinafter, the hoisting machine of the elevator of this invention is demonstrated in detail based on an Example.

[0057] figure 1 It is a configuration diagram showing a hoisting machine 101 of an elevator according to an embodiment of the present invention. This hoisting machine 101 is composed mainly of a motor 110 , a sheave 120 and a base 130 .

[0058] The hoisting machine 101 has first to third oil guide structures. These oil guide structures prevent oil from adhering to the disc brake even if oil leaks from the bearing portion on the sheave side. Details will be described later.

[0059]

[0060] The motor 110 is mounted and fixed on the base 130 .

[0061] The casing 111 of the motor 110 is formed of the first bracket B1, the second bracket B2, and the frame F. As shown in FIG. The first bracket B1 has a first bearing portion b1, and the second bracket B2 has a second bearing portion b2.

[0062] The rotating shaft S on which the rotor 112 is located is ...

Abstract

To prevent oil from adhering to a brake disc when the oil leaks from a bearing unit. A first bearing unit (b1) of a motor (110) is disposed in a state of being inserted into a bearing unit insertion part (124) of a sheave (120), and is therefore positioned on the inner peripheral side of a rope winding part (122). The rope winding part (122) of the sheave (120) has a brake disk (D) formed integrally therewith on the motor side. In order to prevent oil from reaching the brake disk (D) when oil leaks out from the first bearing unit (b1), three systems of oil guide structures (210, 220, 230) for guiding leaked oil to a position set apart from the brake disk (D) are provided.

Description

technical field [0001] The present invention relates to an elevator traction machine, and more particularly to an elevator traction machine intended to prevent oil leaked from a bearing from adhering to a brake disc. Background technique [0002] The traction machine of the elevator is composed of a motor and a sheave (rope sheave) as the main components. As a type of traction machine, there is a type in which a sheave is supported on one side by a rotating shaft of a motor. [0003] In the one-side support type hoisting machine as described above, efforts have been made to reduce the size in the axial direction and reduce the size and weight (for example, refer to Patent Document 1). [0004] refer to image 3 An outline of a one-side support type hoisting machine as disclosed in Patent Document 1 will be described. This hoisting machine 1 is composed of a motor 10 and a sheave 20 as main components. [0005] The rotating shaft S of the motor 10 is rotatably supported by...
