Detailed description of the invention
Fig. 1 shows a specific embodiment of this outer rotor tractor of the utility model, and it is primarily of casing A, rotor B and drg C, and its rotor B is arranged in casing A, and drg C matches with rotor B and transfers to use to play braking to rotor.
The key improvements of this example is that the version of described casing A and rotor B is different from conventional art, specific as follows:
As shown in Figure 2 to 4, it is formed primarily of a support frame 1 and a supporting plate 2 concrete structure of described casing A.Wherein support frame 1 is made up of the left side wall 1b be arranged in parallel and right side wall 1a and four the dowel 1c be vertically connected between described left side wall 1b and right side wall 1a, and this four dowel 1c and left side wall 1b, right side wall 1a are integral type structure.Right side wall 1a is shaped with the first rotor supported hole (not marking in figure) for support rotor, and forms the clutch shaft bearing gear 1e bearing radial load in the inner side of this first rotor supported hole.Supporting plate 2 is shaped with the second rotor supports hole (not marking in figure) for support rotor, and forms the second bearing gear 2b bearing radial load in the inner side in this second rotor supports hole.Left side wall 1b is shaped with supporting plate knock hole 1d, supporting plate 2 forms with supporting plate knock hole 1d to the seam 2a coordinated, supporting plate 2 is vertically fixedly connected on left side wall 1b, and the seam 2a on supporting plate 2 penetrates in the supporting plate knock hole 1d on left side wall 1b.
The concrete structure of described rotor B as shown in Figure 5 and Figure 6, it primarily of main shaft 5, be disposed coaxially on this main shaft peripheral and the rotor wall body 6 of cylindrical structure and the connecting wall 3 be vertically connected between described main shaft and rotor wall body and form, and main shaft 5, rotor wall body 6 and connecting wall 3 is integral type structure, three in one is shaping, is shaped with traction grooving 4 at the outside face of rotor wall body 6 simultaneously.
Mounting structure between casing A and rotor B can refer to shown in Fig. 1, is specially: one end of main shaft 5 penetrates the first rotor supported hole on described right side wall 1a, and by bearings in described clutch shaft bearing gear 1e.The other end of main shaft 5 penetrates the first rotor supported hole of described supporting plate 2, and by bearings in described second bearing gear 2b.Article four, dowel 1c is arranged in rotor wall body 6 periphery, and every bar dowel 1c and rotor wall body 6 spaced apart, when so can ensure practical application, elevator rope can be wrapped on the traction grooving 4 of rotor wall body 6, and can pass that casing A is outer to be connected with lift car smoothly.
The C of drg described in this example is arranged in the outside of right side wall 1a.
When assembling described casing A, the seam 2a on supporting plate 2 aimed at and penetrates in the supporting plate knock hole 1d on left side wall 1b, thus ensure that the concentricity between supporting plate 2 and support frame 1.
During practical application, the two ends of rotor main shaft 5 keep off in 2b at described clutch shaft bearing gear 1e and the second bearing respectively by bearings, thus dependence clutch shaft bearing gear 1e and the second bearing gear 2b bears the powerful radial load that rotor is subject to.This structure is when clutch shaft bearing gear 1e and the second bearing gear 2b is subject to radial bearing capacity, and can ensure the stability of structure, safety performance significantly improves, and deflection significantly reduces, and uses quantity of material also significantly to reduce, and design redundancy also significantly increases.
In this example, the outline (outer peripheral edges) of described left side wall 1b and right side wall 1a is rectangular configuration, and four described dowel 1c are connected between four drift angles of these two rectangular configuration.Nature, these four rectangular distributions of dowel 1c, and be spaced from each other.
This example offers corresponding screw hole on described supporting plate 2 and left side wall 1b, and described supporting plate 2 is fixed together by locking screw in described screw hole with left side wall 1b.And after installation, the outer face 1f of described left side wall 1b and the inner end surface 2c of described supporting plate 2 is close to layout.
With reference to shown in Fig. 5 and 6, because the groove number of traction grooving 4 does not need too much during practical application, consider reduction cost of manufacture simultaneously, this example does not all arrange traction grooving 4 on the whole axial length of rotor wall body 6, and make described traction grooving 4 only be arranged at the outside face of rotor wall body 6 near that one end of connecting arm 3, and the longitudinal central portion of traction grooving 4 is close to the connecting portion of described connecting arm 3 and rotor wall body 6, the longitudinal central portion of preferred traction grooving 4 coincides with the connecting portion (namely the axial centre of traction grooving 4 is positioned at the thickness range of connecting arm 3) of described connecting arm 3 and rotor wall body 6.And the diameter of described main shaft 1 diminishes gradually to two ends centered by connecting arm 3.This structure forms the rigid construction body of a relative symmetry, and when traction grooving 4 is subject to diametral load, the structure of its relative symmetry makes its overall mean forced, and rigid nature is better.
When being subject to diametral load on the traction grooving 4 of this towing machine, power is transmitted to connecting arm 3 by rotor wall body 6, main shaft 1 is transmitted to again by connecting arm 3, on the clutch shaft bearing gear 1e that power is transmitted to two ends by main shaft 1 again and the second bearing gear 2b, wherein the longitudinal central portion of traction grooving 4 is close to the junction of connecting arm 3 and rotor wall body 6, therefore the center of power is also close to connecting arm 3, improves the ability of rotor bearing load; Power is transmitted to main shaft 1 by connecting arm 3, and main shaft 1 diminishes gradually to two full and uniform being distributed on main shaft 1 of exerting all one's strength.
Certainly, above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to people can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, all should be encompassed within protection domain of the present utility model.
