Summary of the invention
The technical problem to be solved in the present invention
In conventional lift jacking system with above-mentioned cantilever sheave supporting structure, size A by utilizing the end towards sheave side bearing 107 to fluted roller shaft load centre (middle part of steel rope coiling surface 114) of axle 106 overhanging size or length D, from the size B at sheave side end face to the middle part of sheave side bearing 107 of sheave side bearing 107 and distance or spacing C and by following formula 1 expression from the sheave side end face of sheave side bearing 107 to steel rope coiling surface 114 towards the end of sheave side bearing 107 from steel rope coiling surface 114.
D=A+B+C formula 1
Below formula 2 and 3 by utilize between the middle part of the middle part of sheave side bearing 107 and sheave opposition side bearing 108 apart from E, be applied to the power L1 on the sheave side bearing 107 and the power L2 that is applied on the sheave opposition side bearing 108 obtains by fluted roller shaft load W.
L1=W (D+E)/E=W (A+B+C+E)/E formula 2
L2=WD/E=W (A+B+C)/E formula 3
Shown in formula 2 and 3, in the structure of existing bont, when needs had the sheave 12 of big width, it is bigger that size A becomes, and overhanging dimension D becomes bigger, so power L1 and L2 increase.Therefore, bont needs larger sized bearing, axle and framework, thereby causes the shortcoming that bont weight increases and cost increases.
Even when the sheave width increased, size E may increase pro rata with the increase of the dimension D of Fig. 6, thereby did not need bigger bearing and axle.But, in this case, the length of framework and axle is owing to the increase of size E increases.Therefore, the overall dimension of bont and installing space increase, and bont runs into the problem that weight increases and cost increases.
And axle is owing to fluted roller shaft load W is subjected to moment of deflection M.
M=WD=W (A+B+C) formula 4
Have at sheave under the situation of bigger width, size A is bigger, and moment of deflection M becomes bigger, as by formula 4 obviously as can be known.Therefore, in order to solve the sheave bevelled problem that causes of axle deflection that causes owing to fluted roller shaft load W, bont need use has the thicker axle of major axial diameter, runs into therefore that weight increases and the shortcoming of cost increase.
When sheave width and sheave load were big, existing system utilized the bont 120 of double supporting structure, and this bont 120 has the sheave 124 between the bearing 122 and 123 of bolster 121, as shown in Figure 7.But, the shortcoming in this structure of two-side supporting sheave is to be difficult to install and the replacing sheave after the bont assembling.
The bont that the purpose of this invention is to provide a kind of cantilever design, it is applicable to more big grooved wheel width and more big grooved wheel load.

The specific embodiment
Fig. 1 has represented according to the elevator hoist apparatus of first embodiment or equipment 1.Elevator hoist apparatus 1 comprises stator 4 and rotor 11.Stator 4 is by attached with stator core 3 or be fixed on going up in interior week of framework 2 and form.Rotor 11 forms by by clutch shaft bearing 7 (hereinafter being called the sheave side bearing) and second bearing 8 (hereinafter being called sheave opposition side bearing) axle 6 being can be rotated to support on first carriage 9 that is installed in the framework 2 and second carriage 10, and rotor core 5 is attached or be fixed on this axle 6.Elevator hoist apparatus 1 also comprises sheave 12 (wheel with groove is used to make rope turn round (run on) in the above), and this sheave 12 is installed on the protrusion end sections of axle 6, and described protrusion end sections is protruding to the outside of sheave bearing 7.
In first embodiment, sheave side bearing 7 is positioned to, the 7 whole insertions of sheave side bearing and cover position in the bearing insertion portion 15 and sheave side bearing 7 towards the position of end face between the position of fluted roller shaft load centre of fluted roller shaft load centre.Relation between the position of the position of sheave side bearing 7 and sheave 12 is represented by following mathematic(al) representation: 2B＜C＜A.
By sheave side bearing 7 is placed in the bearing insertion portion 15, as mentioned above, compare with the prior art bont shown in Fig. 6, can reduce overhanging dimension D.Therefore, the power L1 that acts on the sheave side bearing 7 becomes littler with the value that acts on the power L2 on the sheave opposition side bearing 8, therefore can reduce the size and the weight of these bearings, axle and framework, and cost-cutting.And, because the moment of deflection M that fluted roller shaft load W causes also becomes littler.Therefore,, also can reduce the axle deflection that causes owing to fluted roller shaft load W, and reduce the inclination of sheave even under the situation of thin axle.
Fig. 2 has represented the elevator hoist apparatus 1 according to second embodiment.In a second embodiment, the sheave side bearing 7 that inserts in the bearing insertion portion 15 is located such that the width middle part or the mid point of the broad ways of sheave side bearing 7 are positioned at fluted roller shaft load centre place.This relation between the position of the position of sheave side bearing 7 and sheave 12 is represented by following mathematic(al) representation: C=A+B.In others, second embodiment is identical with first embodiment, and omits repeat specification.
Be positioned at fluted roller shaft load centre place by middle part with the broad ways of sheave side bearing 7, as mentioned above, can be so that overhanging dimension D be decreased to zero.Therefore, the size of power L1 becomes and equals fluted roller shaft load W, thereby compares the radial load that can reduce to be applied on the sheave side bearing 7 with the structure of claim 1.And, be applied to power L2 on the sheave opposition side bearing 8 and become and equal zero, thereby compare the size that can further reduce bearing with the structure of claim 1.Therefore in addition, eliminated the moment of deflection M that causes owing to fluted roller shaft load W, axle does not carry out deflection yet, can also eliminate since spool the inclination of the sheave that causes of deflection.In addition, can be so that thinner lighter on the shaft size with weight.
Fig. 3 has represented the elevator hoist apparatus 1 according to the 3rd embodiment.In the 3rd embodiment, sheave side bearing 7 is located such that the width middle part of sheave side bearing 7 broad wayss or the outside (at the opposition side of fluted roller shaft load centre, opposite with a side at sheave opposition side bearing 8 places) that mid point is positioned at the fluted roller shaft load centre.Relation between the position of the position of sheave side bearing 7 and sheave 12 is represented by following mathematic(al) representation: 0＜D.
As mentioned above, fluted roller shaft load W is bearing between sheave side bearing 7 and the sheave opposition side bearing 8.Therefore, the deflection that this configuration can restrictive axes, eliminate the inclination of sheave, and support sheave with stable status, similar with the bont of the double base type shown in Fig. 7.In addition, this configuration can keep the good usability of type of cantilever bont.
In the example of first to the 3rd embodiment shown in Fig. 1-3, sheave 12 is fixedly mounted on the end sections of axle 6 by contraction fit.But, can select to use the configuration shown in the Figure 4 and 5.In the configuration of Figure 4 and 5, the end sections of axle 6 inserts in the axle insertion portion 16 that is formed in the sheave 12, and is fixed to sheave 12 by nut 17 or bolt 18.These configurations can handled easily, for example replacing of sheave.
