Compared with the prior art, the external rotor permanent magnetic synchronous no-gear tractor has the advantages of small jumping of surface of the traction wheel trough, high concentricity of rotor, convenient replacement of traction wheel, compact structure of whole machine, low height of whole machine, being used in no-machine rooms.
Description
Technical field
The present invention relates to a kind of towing machine, particularly the elevator permanent-magnetic synchnorous gearless dragging machine.
Background technology
Existing external rotor type permanent magnetism synchronous gearless machine structure as shown in Figure 1, traction sheave is installed in the front end of rotating shaft, rotor is installed on the traction sheave inner end surface.Be unlikely to oversize in order to control cantilever on the one hand, on the other hand for saving traction sheave material and control complete machine length, so traction sheave is shorter with the section of cooperation of axle, therefore, often occur following problem aborning: 1 traction sheave wheel rooved face is beated overproof; The coaxiality error of 2 traction sheaves can pass to rotor, causes rotor outer surface to beat seriously; 3 because cumulative errors are big, cause rotor and rotating shaft decentraction often to occur.At the problems referred to above, Chinese patent 200610050802.9 (minitype permanent magnetism synchronization gear wheel free traction machine) has proposed a kind of traction sheave and axle is cast into the structure of one, add man-hour, the processing simultaneously of traction sheave and axle can overcome the problems referred to above that existing external rotor type permanent magnetism synchronous gearless machine exists, but because traction sheave is a vulnerable part, need after the wearing and tearing to change, and this structure need connect rotating shaft when changing and changes together, and when changing, rotor all be extracted, it is very inconvenient to operate.
Summary of the invention
The object of the invention just provide a kind of traction sheave surface beat little, the external rotor type permanent magnetism synchronous gearless machine easily that rotor concentricity height, traction sheave are changed.
The present invention realizes like this; The traction sheave that comprises support, is arranged on internal stator on the support, rotates the outer rotor that is arranged on the internal stator outside, is arranged on rotating shaft on the support, is fixed in the rotating shaft and is fixed together with outer rotor by bearing, its special feature is: the rotating shaft front end is provided with spoke, spoke and axle and is casting integrated structure, and traction sheave is fixed on the spoke.
Because axle is casting integrated structure with spoke, add man-hour, axle is processed with spoke, so the axle and the right alignment of spoke are easy to guarantee that and traction sheave and spoke has bigger cooperation area and an end face area of contact, the assurance so traction sheave wheel rooved face run-out tolerance is easy to get, equally, rotor is directly installed on the spoke stop portion, does not exist the coaxiality error of traction sheave can pass to the rotor problem, so, rotor concentricity height.
Here, dismounting for convenience and installation, the traction sheave hole cooperates with spoke outboard face, and is axially fixed on the spoke by fastener.
Use for convenience, particularly use at no machine room environment, the support both sides are provided with the sinking step, and ringbolt is arranged on the support sinking step.When permanent-magnet synchnorous gearless dragging machine when no machine room environment uses, to highly being that certain limitation is arranged, adopt design-calculated support of the present invention, can reduce whole height of devices effectively.
Compared with the prior art the present invention has beat little, rotor concentricity height, traction sheave of traction sheave wheel rooved face and changes convenient, compact integral structure, and the complete machine height is low, the advantage that can use in no machine room.
Description of drawings
Fig. 1 is the structural representation of prior art;
Fig. 2 is a constructional drawing of the present invention;
Fig. 3 is the left view of Fig. 2.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described:
The structure of a kind of external rotor type permanent magnetism synchronous gearless machine of the present invention as shown in Figure 2, its structure mainly is made up of axle 1, front bearing 2, spoke 5, traction sheave 7, outer rotor 9, internal stator 10, support 11, rear bearing 12, drg 13, internal stator 10 fastening being installed on the support sleeve that stretches out support 11 inside, outer rotor 9 is in stator 10 outsides and is fixed on the right-hand member of spoke 5 by rotor screw 8, left end at spoke 5, be fixed with traction sheave 7, axle 1 is casting integrated structure with spoke 5, is supported by the front bearing 2 and the rear bearing 12 that are installed in the support.Because axle 1 is structure as a whole with spoke 5, add man-hour, process together, so the right alignment of axle 1 and spoke 5 is easy to guarantee, spoke 5 lateral surfaces directly cooperate with the traction sheave hole, and be fixed on the end face of spoke 5 by bolt 6, traction sheave 7 and spoke 5 are by radially locating with end face, utilize screw 6 to axially fasten, because it is both end face area of contact are bigger,, same so traction sheave 7 is taken turns the assurance that is easy to get of rooved face run-out tolerance, outer rotor 9 is directly installed on spoke 5 right stop portions, by radially locating with end face, axially fasten with rotor screw 8 too, the coaxiality error of having eliminated traction sheave 7 passes to outer rotor 9 problems, so, outer rotor 9 and axle 1 concentricity height.
Be for convenience detach and installation bearing cap shim 3, design has cooresponding screw hole 4, spanner can conveniently stretch into dismounting or fastening on spoke.
When permanent-magnet synchnorous gearless dragging machine used in no machine room, to certain limitation is highly arranged, design-calculated support of the present invention 11 both sides were provided with sinking step 15, and ringbolt 14 just in time is installed on the support sinking step 16.
The drg 13 that the present invention adopts is a block brake, is arranged on support 11 both sides, symmetric arrangement, and rotor directly uses as brake wheel, certainly, adopts the technical program, and drg can be used drum brake mechanism, plate disc brake etc. equally.
