Embodiment approach 1

[0028] figure 1 It is a sectional view of the hoisting machine 100 showing a state in which the housing 30 is assembled to the rotating shaft 10 using the hoisting machine assembly aid 70 in Embodiment 1 of the present invention. also, figure 2 yes figure 1 Enlarged view of part A.

[0029] Such as figure 1 As shown, the hoisting machine 100 has a rotating shaft 10 , a sheave 20 , and a casing 30 as an assembled component assembled to the rotating shaft 10 . One axial end side of the rotary shaft 10 is rotatably supported by a bearing housing 50 via a bearing 40 . On the other hand, the other axial end side of the rotary shaft 10 is rotatably supported by the housing 30 via a bearing 41 . The bearing housing 50 and the housing 30 are fixed on the traction frame 200 . also, figure 1 A state in which the hoisting machine assembly aid 70 is attached to the hoisting machine 100 is shown. When operating the hoisting machine 100, the hoisting machine assembly aid 70 is disa...

Abstract

The traction machine assembly aid is an aid for assembling the assembled parts with threaded holes on the rotating shaft. The threaded hole is formed with an internal thread part. The traction machine assembly aid has a main body and a connecting mechanism. The male threaded portion screwed with the female threaded portion connects the main body to the end of the rotary shaft so as to be coaxial with the rotary shaft and rotatable relative to the rotary shaft. Thereby, the traction machine assembly auxiliary tool and the traction machine assembly method which can reduce the burden of an operator with a simple structure can be obtained.

Description

technical field [0001] The present invention relates to a traction machine assembly aid for an elevator that rotates a sheave around which a main rope is wound to move a car chamber up and down, and a traction machine assembly method using the traction machine assembly aid. Background technique [0002] In the past, in the assembly of the traction machine of the elevator, in the operation of assembling the frame with the rotor or the housing with the stator on the rotating shaft, due to the attractive force of the rotor and the stator, the center of the rotating shaft and the diameter of the frame or housing The center of the direction may be shifted, and the workability is poor. [0003] Therefore, a technique has been disclosed in which a plurality of guide rollers are attached inside the rotor frame, and each guide roller is arranged along the outer periphery of the stator so that the center of the rotating shaft and the center of the rotor frame do not deviate. In addit...
