The birds-eye view that the birds-eye view that Fig. 4 is expression when the position of the arrow B of Fig. 3 is observed, Fig. 5 are expressions when the position of the arrow C of Fig. 3 is observed.As shown in Figure 5, working fastening part 37 is not constituted as along the whole circumference direction of rotating frame 7 extends towards internal side diameter, extends towards internal side diameter but be constituted as in required parts, place such as bolt hole 49 and positioning seat portion 35 are set.At this, equally spaced have a plurality of working fastenings place in a circumferential direction, just be used to be provided with the place of bolt hole 49 and through hole 36.For example; As shown in Figure 6, in the upper right side, when working fastening is carried out in 4 places of lower right, upper left side and lower left, and compare in the occasion of carrying out working fastening up and down; Because very low hole, location not is so can position the dismounting and the installation exercise of bolt 30 more easily.
Fig. 7 is the detailed structure view as the dowel bolt 30 of screwing device.As shown in Figure 7, the dowel bolt 30 in the present embodiment has head 31, axial region 32 and threaded portion 33.In addition, be provided with the operating groove 48 that is roughly regular hexagon on the surface of head 31, for the ease of inserting and chimeric, be provided with sweep in the part of head 31 and axial region 32.And, be not limited in bolt and constitute dowel bolt 30, as long as have threaded portion 33 grades and can play the effect identical, then also can use the screwing device of other structures with present embodiment.
Fig. 8 is the enlarged drawing of the A part of Fig. 1, and this dowel bolt 30 of expression is inserted in the state in the bolt hole 49 of through hole 36 and rotating frame 7 of shell 1 in Fig. 8.As shown in Figure 8, dowel bolt 30 has rotating frame 7 the further function of bolt of the what is called of shell 1 that furthers.In addition, screw togather through the bolt hole 49 with threaded portion of dowel bolt 30 33 and rotating frame 7 sides, dowel bolt 30 is fixed with rotating frame 7, and mobile on the horizontal direction obtained restriction.On the other hand; Owing to do not have screw thread on the inner peripheral surface of the outer peripheral face of the axial region 32 of dowel bolt 30 and the through hole 36 of shell 1; So dowel bolt 30 is not restricted with respect to moving of shell 1 in the horizontal direction; Wherein, especially dowel bolt 30 is not restricted towards extracting moving of direction.
Therefore, in the present embodiment,, be provided with and release bolt 46, limit dowel bolt 30 thus towards extracting moving of direction like Fig. 9 and shown in Figure 10.In addition, Fig. 9 is the figure when observing from the position of the arrow D of Fig. 8, and Figure 10 is the figure when the position of the arrow E of Fig. 9 is observed.
At first, as shown in Figure 9, the restraint location of releasing bolt 46 is different with the restraint location of dowel bolt 30 in a circumferential direction.Thus, can dwindle the amount that stretch out towards interior all sides the end of the required rotating frame of binding bolt 7, its result makes rotating frame 7 single-piece structures become simple.
In addition, shown in figure 10, except the through hole 36 of dowel bolt 30 usefulness, also the lateral parts 21 at shell 1 is provided with the bolt hole of releasing bolt 46 usefulness.And, release on the relative outer peripheral face of bolt hole in the bolt 46 and be provided with screw thread with shell 1, release bolt 46 and screw togather with shell 1.For this reason, rotating frame 7 when the direction near shell 1 moves with the front end butt of releasing bolt 46, it moves and is restricted.Its result through dowel bolt 30 and release bolt 46, can prevent to produce deviation in the horizontal direction between shell 1 and the rotating frame 7 when changing rope sheave 2 grades reliably.
In addition, as shown in Figure 8 in the present embodiment, at least a portion of the head 31 of dowel bolt 30 is inserted into and is entrenched in the positioning seat portion 34, and the inner peripheral surface of bolt 34 is fixed because this part is positioned, so dowel bolt 30 mobile being restricted diametrically.Therefore; Even have delicate gap because of not screwing togather between the through hole 36 of the axial region 32 of dowel bolt 30 and shell 1; But owing to positioning seat portion 34 is entrenched togather with head 31, so can prevent to produce deviation in vertical direction between shell 1 and the dowel bolt 30.In addition, through screwing togather between bolt hole 49 and the threaded portion 33, can prevent to produce deviation in vertical direction between rotating frame 7 and the dowel bolt 30.Its result can keep rotor 8 that is supported by rotating frame 7 and stator 6 relative position in vertical direction that is supported by shell 1, even under the situation of pulling down rope sheave 2 grades, also can the air gap between rotor 8 and the stator 6 be maintained state of equalization.
And; In the present embodiment; In the working fastening part 37 of rotating frame 7, also be provided with positioning seat portion 35; Through the part of the axial region 32 of dowel bolt 30 is inserted and is entrenched in the positioning seat portion 35, the be positioned inner peripheral surface of a portion 35 of dowel bolt 30 is fixed its mobile being restricted diametrically.Thus; Not only can rely on screwing togather and prevent to produce in vertical direction deviation effectively between bolt hole 49 and the threaded portion 33; But also can rely on positioning seat portion 35 to come to prevent effectively to produce in vertical direction deviation; Therefore, the accuracy rate of the working fastening between rotating frame 7 and the shell 1 further improves, thereby can further improve the accuracy of positioning of rotating member 8 and stator 6.
Below, the step of the replacing operation of rope sheave 2 grades of the winch in the present embodiment 50 is described.At first, dowel bolt 30 is inserted in the through hole 36 of shell 1, the bolt hole 49 of rotating frame 7 is screwed togather with threaded portion 33.When the fastening end of dowel bolt 30, the inner peripheral surface butt of the outer peripheral face of the part of head 31 and positioning seat portion 34, rotor 8 is arrived with the core position by self-orientation with stator 6.After this, with releasing the bolt hole that bolt 46 inserts shell 1, to limit rotating frame 7 towards shell 1 side shifting.Afterwards, drg 5, bolt 14 and bearing stand 9 etc. are pulled down, changed new with bearing 4A, 4B etc. rope sheave 2.
Therefore, in the present embodiment, only need unload rope sheave 2 grades just can, and need the housing parts 20 of rotor 8 from shell 1 do not removed, therefore, do not need to overcome the very big attractive force of generation between rotor 8 and stator 6 on one side, Yi Bian carry out operation.And, owing to remain on the position with core through positioning seat portion 34 etc. between rotor 8 and the stator 6, so not only can in the replacing operation of rope sheave 2 grades, suppress the generation of deviation, and need be at the relative position of adjusting after the replacing between rotor 8 and the stator 6.In addition, because the relation of the position between rotating frame 7 and the shell 1 has obtained keeping,, the installation exercise itself of rope sheave 2 and bearing 4A, 4B etc. also becomes convenient so being installed.Its result, rope sheave 2 grades change the also shortening significantly of required time of operation.
In addition, move in the building, perhaps when changing whole winch 50 at the winch 50 that the elevator that will newly install is used; Operation for ease need reduce the weight of winch 50, sometimes according to present embodiment; Can cut apart winch 50; Shown in figure 11, will separate carrying with rope sheave 2 etc. by the winch 50 usefulness electrical motors that rotor 8, stator 6 and shell 1 constitute, in the place that is provided with of elevator rope sheave 2 grades are installed on the winch then.At this moment, therefore bolt 30 working fastenings such as grade because rotating frame 7 and shell 1 are positioned can prevent that rotor 8 and stator 6 from bumping because of the vibrations in the carrying way and damage etc.In addition, owing to rotor 8 and stator 6 remain on the position with core through positioning seat portion 34 grades, so, when rope sheave 2 grades are installed with assembling winch 50, need not carry out the adjustment operation of the relative position between rotor 8 and the stator 6.
Figure 12 and Figure 13 are that the fixed frame of expression the present invention the 2nd embodiment is the figure of the method for temporarily fixing between shell 1 and the rotating frame 7.Like Figure 12 and shown in Figure 13, in the lateral parts 21 of shell 1, the outer circumferential side that is provided with the lateral parts 21 of through hole 36 partly forms towards the positioning combination part 45 of rotating frame 7 lateral processes.On the other hand, in the side that is arranged in shell 1 side of rotating frame 7, form positioning combination part 39 thereby recess is set in the periphery side sections.In addition, also can the structure of present embodiment be turned around, recess is set, and protuberance is set in rotating frame 7 sides in shell 1 side.
So, through opposite face the part of concavity or convex is set respectively, and makes the part of these concavities or convex chimeric each other, can prevent that rotor 8 and stator 6 relative position in vertical direction from producing deviation at rotating frame 7 and fixed frame.
Below, the shell 1 of present embodiment and the method for temporarily fixing between the rotating frame 7 are described.At first, bolt 15 grades are disassembled, formation can make S. A. 3, rope sheave 2 and rotating frame 7 S. A. 3 axially on the state that moves towards shell 1.Afterwards, the bolt 44 of furthering is inserted the through hole 36 of shells 1, threaded portion 33 and bolt hole 38 are screwed togather, with rotating frame 7 shell 1 that furthers, finally make rotating frame 7 and shell 1 butt simultaneously.
At this moment, the inner peripheral surface of the outer peripheral face of the positioning combination part 39 of rotating frame 7 and the positioning combination part 45 of shell 1 is chimeric, rotating frame 7 mobile being restricted diametrically.In addition, because very close to each other in the horizontal direction between rotating frame 7 and the shell 1, so rotating frame 7 can not produce deviation in the horizontal direction, so, releasing bolt 46 even be not provided with, also can rotating frame 7 be temporarily fixed on the shell 1., in the present embodiment, be with the difference of the 1st embodiment that the structure of rotating frame 7 and shell 1 grade becomes more simple, it is more convenient that the working fastening operation also becomes for this reason.
