no. 1 Embodiment approach

[0044] Next, refer to image 3 and Figure 4 The elevator driving device 1 according to the first embodiment of the present invention will be described in detail.

[0045] Such as image 3 and Figure 4 As shown, the outer side brake housing 43 has an opening 51 (that is, a window or a notch) in a region facing the pulse generator 26 , and the opening 51 exposes the pulse generator 26 to the outside of the brake housing 27 . The opening part 51 is formed on the extension line of the axial center of the 2nd motor shaft 32, and opens in the horizontal direction. The opening 51 is formed, for example, in a rectangular shape. That is, the opening 51 is opened on the side surface of the brake housing 27 opposite to the motor main body 30 .

[0046] Here, the outer diameter of the rotating body (for example, the outer diameter D1 of the brake disc 25 ) is larger than the outer diameter of the tip structure (for example, the outer diameter D2 of the pulse generator 26 ). Such a...

no. 2 Embodiment approach

[0059] Below, refer to Figure 5 to Figure 7 A drive device 1 for an elevator according to a second embodiment of the present invention will be described. In addition, the same code|symbol is attached|subjected to the structure which is the same as the structure of said 1st Embodiment, or has a similar function, and description is abbreviate|omitted.

[0060] Such as Figure 5 As shown, the brake housing 27 of this embodiment includes hinge portions 61 , 62 that connect the horizontal end portion (first end portion 52 a ) of the cover 52 to the brake housing main body 41 . An example of the hinge parts 61 and 62 is a hinge member. Such as Figure 6 and Figure 7 As shown, the cover 52 is rotatably supported in the horizontal direction by hinges 61 and 62 . In addition, the term "rotatable in the horizontal direction" means freely rotatable about an axis extending in the vertical direction. In addition, the number of hinge parts 61 and 62 may be one.

[0066] Below, refer to Figure 8 to Figure 10 A drive device 1 for an elevator according to a third embodiment of the present invention will be described. In addition, the same code|symbol is attached|subjected to the structure which is the same as the structure of said 1st and 2nd embodiment, or has a similar function, and description is abbreviate|omitted.

[0067] Such as Figure 8 As shown, the brake housing 27 of this embodiment includes hinge portions 71, 72 that connect the end portion (first end portion 52c, for example, the lower end portion) of the cover 52 in the vertical direction with the brake housing main body. 41 links. Such as Figure 9 and Figure 10 As shown, the cover 52 is rotatably supported in the vertical direction by hinges 71 and 72 . In addition, the term "rotatable in the vertical direction" means freely rotatable about an axis extending in the horizontal direction. Such as Figure 10 The cover 52 detached from the brake housing main body 41 ...

Abstract

An elevator driver (1) is provided at the top (3a) of a lifting path (3) for lifting the cage (6). The elevator driver comprises the following components: a motor (21) which is provided with motor shafts (31, 32) that are rotatably driven; rotating members (22, 25) which are equipped to the motor shafts (31, 32); front structures (23, 26) which are equipped to the front ends of the motor shafts (31, 32); and housings (24, 27) which surround the rotating members (22, 25) and front structures (23, 26). The housing surround the rotating members and the front structures and comprises the followingcomponents: housing bodies (34, 41) which are provided with openings (51, 56) that expose the front structures (23, 26) to the outside of the housings (24, 27) at the area opposite with the front structures (23, 26); and covers (52, 57) which are detachably provided on the housing bodies (34, 41) for covering the openings (51, 56).

Description

technical field [0001] The present invention relates to a driving device for an elevator provided with a casing. Background technique [0002] A drive device for an elevator includes: a brake disc mounted on a motor shaft; a pulse generator mounted on a front end of the motor shaft; and a brake housing surrounding the brake disc and the pulse generator. The above-mentioned brake housing is composed of a plurality of housing constituent members. The maintenance work of the pulse generator is carried out by disassembling the above-mentioned multiple housing components in the liftway. [0003] JP 2006-256759 A discloses an elevator driving device including a brake housing. The drive device includes a brake that brakes the motor, and a brake housing that covers the brake. The brake case includes a lower case covering the lower side of the brake and an upper case covering the upper side of the brake. [0004] In elevators that have been miniaturized in recent years, the margi...
