Problems solved by technology

Therefore, it cannot be applied to various car sizes
In addition, in order to be applicable to various car sizes, it is necessary to enlarge the lead-out opening of the main rope 18 of the base body, but on the contrary, the strength of the base body is reduced.
In addition, in order to compensate for the decrease in the strength of the base, it is necessary to configure the base firmly, so the increase in size leads to a decrease in mountability and uneconomical

Embodiment approach 1

[0028] Figure 1 to Figure 3 is a diagram showing Embodiment 1 of the present invention, figure 1 is the main view, figure 2 is along figure 1 A cross-sectional view of line A-A in, image 3 It is a bottom view. In the figure, the base body 1 has a first mounting portion 1a and a second mounting portion 1b both mounted on a stand not shown in the figure, and is provided with a mounting bracket erected from the first mounting portion 1a and the second mounting portion 1b. The column portion 1c has a cylindrical concave portion 1d integrally formed on the column portion 1c, and a cylindrical convex portion 1e integrally formed in the central portion. In addition, a bearing 2 as a pivot attachment portion is accommodated in the boss portion 1e, and the rotating shaft 3 is pivotally supported by the bearing 2 . Moreover, the bearing 2 is arrange|positioned near the column part 1c. In addition, the bearing 2 is an ordinary ball bearing, which rotates by rolling spherical b...

Embodiment approach 2

[0053] Figure 6 Embodiment 2 of the present invention is shown. Based on Embodiment 1, this embodiment is as follows Figure 6 As shown, the bearing 2 a is arranged such that a part of the bearing 2 a overlaps the drive sheave 4 on a projection viewed from the radial direction of the rotating shaft 3 . In addition, one end portion of the rotating shaft 3 is formed in a flange shape, and the drive sheave 4b is fixed to the flange portion with a bolt 6g, and the rotor is fixed to the other end portion of the rotating shaft 3 by shrink fitting. 5a. In addition, the same reference numerals as in Embodiment 1 denote corresponding parts.

[0054] In the traction machine for an elevator thus constituted, since the bearing 2a is arranged such that a part of the bearing 2a overlaps the driving sheave 4 in a projection viewed from the radial direction of the rotating shaft 3, the bearing 2a and the driving sheave 4 overlap each other. The distance L3 between the suspended loads F b...

Embodiment approach 3

[0057] Figure 7 Embodiment 3 of this invention is shown. Based on Embodiment 1, this embodiment uses figure 2 The rotor 5 is integrated with the brake rotating body 11, and is provided with a rotor 5b having a brake surface 11a. In addition, the same reference numerals as in Embodiment 1 denote corresponding parts. In addition, this embodiment is shown based on Embodiment 1, However, Based on Embodiment 2, the rotor 5 and the brake rotor 11 can also be comprised integrally.

[0058] By adopting such a configuration, the same effect as that of Embodiment 1 or Embodiment 2 can be obtained. In addition, the number of components can be reduced, and an economical elevator traction machine can be obtained.

Abstract

A hoist for an elevator, small in size and light in weight, having high rigidity, and providing excellent ride quality. More particularly, a hoist for an elevator, capable of being adapted for varied elevator shaft sizes by being combined with a deflection sheave in a machine room. An electric motor is installed next to a pillar section of a base body, a support section for rotatably supporting arotating shaft of the motor is placed near the pillar section, and a drive sheave is provided outside the base body, on the opposite side of the electric motor, so as to be next to the pillar section. Further, a rotor fixed to one end of the rotating shaft and having a field magnet of the electric motor is placed outside the support section and fixed to the other end of the rotating shaft.

Description

technical field [0001] The invention relates to a traction machine for an elevator, which is composed of a base body and a motor. shape. Background technique [0002] In a conventional elevator traction machine, the rotor is pivotally mounted on a fixed shaft through bearings, and the fixed shaft is erected toward the opening side from a column portion of a base body opened on one side, wherein the base body is formed in a bowl shape. In addition, a stator coil of the motor is provided inside the base body, and field magnets arranged to face the stator coil are fastened to the rotor, and a disc-shaped motor is constituted by the stator coil and the field magnet. The driving sheave and the rotor form an integrated structure and are arranged outside the opening side of the base body. In addition, the column portion of the base body supports the suspension load acting on the drive sheave via the main rope, and the column portion of the base body is arranged at a position sepa...
