Abstract
The utility model provides a permanent magnetic synchronous gearless traction machine. The permanent magnetic synchronous gearless traction machine comprises a machine base, a stator, a rotor and a traction sheave, wherein the stator is installed on the machine base, the rotor is connected to the machine base in a rotatable mode, and the traction sheave is fixed to the rotor. The outer side of the stator in the circumferential direction is sleeved with the rear end of the stepped rotor. Magnetic steel is fixedly arranged on the inner wall of the rear end of the rotor corresponding to the stator. The outer circumference of the front end of the rotor is fixedly sleeved with the traction sheave. A plurality of hollow-out holes are formed in the front end face of the rotor. According to the permanent magnetic synchronous gearless traction machine, the hollow-out holes are formed in the front end face of the rotor, so the weight of the rotor is reduced, the thickness of the front end face of the rotor can be increased on the condition of the same quality, and the strength of the rotor is enhanced; on the other hand, when the rotor rotates, the hollow-out hole structure can have a turbulent flow effect on airflow in the traction machine to generate wind, and consequently internal heat dissipation is promoted.
Description
Technical field
The utility model relates to elevator traction machine, relates in particular to a kind of permanent-magnet synchnorous gearless dragging machine.
Background technology
The elevator traction machine of prior art, in order to alleviate own wt, reduces costs, and conventionally adopts the rotor of thinner thickness.But after the thickness attenuation of rotor, it is many that self intensity has also declined simultaneously, causes be affected the service life of towing machine.On the other hand, the rotor of the elevator traction machine of prior art, all adopts enclosed construction, has affected the heat radiation of towing machine.And if at the inner heat abstractor of installing of towing machine, increased equipment cost.
Summary of the invention
In order to overcome the defect of prior art, the purpose of this utility model is to provide one and has alleviated rotor weight and strengthen again rotor self intensity, can also improve the permanent-magnet synchnorous gearless dragging machine of towing machine internal heat dissipating simultaneously.
For achieving the above object, the utility model by the following technical solutions:
A kind of permanent-magnet synchnorous gearless dragging machine, comprise support, be arranged on stator on described support, be rotatably connected to rotor on described support, be fixed on traction sheave on described rotor, it is characterized in that: described rotor is stepped, thereafter the week that end is enclosed within described stator laterally, on the rearward end inwall of described rotor, corresponding described stator is installed with magnet steel, and described traction sheave fixed cover is located at the periphery of the leading section of described rotor; On the front end face of described rotor, offer multiple hollow holes.
Preferably, described permanent-magnet synchnorous gearless dragging machine also comprises the cover plate on the front end face that fixedly covers described rotor.Cover plate can avoid external dust, impurity or foreign matter to enter towing machine inside, and equipment is caused damage.
Preferably, described multiple hollow hole is circumferentially evenly distributed on the front end face of described rotor along same.
More preferably, described hollow hole is fan-shaped.
Further, on the front end face of described rotor, the obstruct section between adjacent two hollow holes divides formation spoiler.
In one embodiment, evenly multiple described spoiler spaced apart tilts along same hand of rotation along the same axis.Owing to adopting this structure, make rotor front end face form a fan assembly, when rotor rotates, can, to the air blast of towing machine inside, increase heat radiation.
Owing to adopting technique scheme, permanent-magnet synchnorous gearless dragging machine of the present utility model has the following advantages: (1) by offering hollow hole on the front end face of rotor, alleviated the weight of rotor, when equal in quality, the front end face thickness of rotor can increase, thereby strengthens the intensity of rotor; (2) when rotor, the hollow hole structure of its front end face produces flow-disturbing effect to the air-flow of towing machine inside, produces wind, thereby increases internal heat dissipating.
Accompanying drawing explanation
Fig. 1 is partial cutaway schematic of the present utility model.
Fig. 2 is schematic perspective view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.
Refer to Fig. 1 to Fig. 3, a kind of permanent-magnet synchnorous gearless dragging machine, comprises support 1, is arranged on stator 2 on described support 1, is rotatably connected to rotor 3 on described support 1, is fixed on traction sheave 4 on rotor 3.Rotor 3 is stepped, and the week that end is enclosed within stator 2 thereafter, on the rearward end inwall of rotor 3, corresponding stator 2 was installed with magnet steel 5 laterally, and traction sheave 4 fixed covers are located at the periphery of the leading section of rotor 3; On the front end face of rotor 3, offer multiple hollow holes 31.On the front end face of rotor 3, be coated with cover plate 6, cover plate 6 is fixedly connected with rotor by screw 61.Cover plate 6 can avoid external dust, impurity or foreign matter to enter towing machine inside, and equipment is caused damage.
On the front end face of rotor 3, multiple hollow holes 31 are along same circumferentially evenly spaced apart, and hollow hole 31 is fan-shaped.Obstruct section between adjacent two hollow holes 31 divides formation spoiler.In the present embodiment, even multiple described spoiler spaced apart, all in axial direction be arranged in parallel along the same axis.Owing to adopting this structure, make the front end face of rotor 3 form a fan assembly, when rotor 3 rotates, can, to the air blast of towing machine inside, increase heat radiation.In another embodiment, evenly multiple described spoiler spaced apart tilts along same hand of rotation along the same axis, can increase the blow rate required and wind speed.
