Abstract

The utility model discloses a permanent-magnet synchronous gearless tractor which is used for various passenger elevators, cargo elevators, sickbed elevators and household elevators and comprises a stator iron core, a traction-wheel end cover, a rotor assembly and a braking-disk end cover, wherein the rotor assembly is provided with a bearing, a stopping opening of the stator iron core is installed by being matched with the traction-wheel end cover, and the rotor assembly with the bearing is installed by being matched with the braking-disk end cover. In the utility model, a stator shell is not needed by the tractor, stopping openings are added to a stator and a machine base, and therefore the material and processing expenses and the installing working procedures of a shell part are reduced, the cost is effectively lowered, and the effective-utilization ratio of materials is increased.

Description

A kind of permanent-magnet synchnorous gearless dragging machine
Technical field
The utility model relates to a kind of permanent-magnet synchnorous gearless dragging machine that is used for all kinds of passenger elevators, cargo elevator, bed lift, home lift.
Background technology
The tradition traction machine stator all has stator foundry goods casing, stator is fixedly mounted on casing inside, this structure all can cause very big difficulty in the installation of motor stator with in reprocessing, all need to use press during Assembly ﹠Disassembly, and need special-purpose press-fitting tool just can carry out, waste time and energy, cost is also high.The existence of stator cage make stator core can not with the air direct contact, the heat of its generation can only pass to air by casing, (under the more frequent situation of towing machine work, the exposed surface metal temperature can reach about 150 degree, necessity is also will increase corresponding protective device), thus be unfavorable for heat radiation.
The utility model content
In order to solve the problem of above-mentioned background technology, the utility model provides a kind of permanent-magnet synchnorous gearless dragging machine, it does not need stator cage, on stator and support, increase seam, thereby the material and the processing charges of housing part have been reduced, and installation procedure, cost-cutting has improved the material effective rate of utilization effectively.
To achieve these goals, the utility model provides following technical scheme:
A kind of permanent-magnet synchnorous gearless dragging machine, be used for all kinds of passenger elevators, cargo elevator, bed lift, home lift, described permanent-magnet synchnorous gearless dragging machine comprises stator core, traction sheave end cap, the rotor assembly that has bearing, brake disc end cap, the seam of described stator core cooperates installation with the traction sheave end cap, and the described rotor assembly that has bearing cooperates installation with the brake disc end cap.
Further, after the described rotor assembly that has bearing is sling, by bolt and nut, bullet pad, flat shim tension.
The beneficial effect that the utility model brings is:
1, overcome stator core and need be applied to press when assembling, made the workman exempt the risk of press operation, saved the man-hour of this operation simultaneously, may cause damage, the rising of casing unshakable in one's determination that have reduced when stator core is pressed into casing are again split.
2, owing to there is not the existence of casing, very convenient during stator core when maintenance, greatly reduce maintenance cost.Owing to do not have casing, saved the casing tooling cost.Directly contacting with air of the iron core of heat generating components was partial to flow air and taken away heat, improved heat-sinking capability unshakable in one's determination greatly owing to casing saves while.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification sheets, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 the utility model structural representation
Number in the figure is:
1-stator core 2-traction sheave end cap 3-has the rotor assembly of bearing
4-brake disc end cap 5-bolt 6-nut
7-bullet pad 8-flat shim
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail.
A kind of permanent-magnet synchnorous gearless dragging machine as shown in Figures 1 to 4, the seam with stator core 1 cooperates installation with traction sheave end cap 2 earlier, lies on the bench board.The rotor assembly 3 that will have bearing installs with brake disc end cap 4.Sling the assembly that installs by bolt 5, nut 6, play pad 7, flat shim 8 tensions, till the seam of the seam of two end cap and stator core 1 is worked good.Fallen assembly with bolt, lain on the platform, unclamped bolt 5, knocked two end cap gently, its bottom surface is contacted with bench board well, used torque-indicating wrench tie bolt 5 at last with copper rod.Described permanent-magnet synchnorous gearless dragging machine does not need stator cage, increases seam on stator and support, thereby has reduced the material and the processing charges of housing part, and installation procedure, and cost-cutting has improved the material effective rate of utilization effectively.
More than a kind of permanent-magnet synchnorous gearless dragging machine that the utility model embodiment is provided be described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; part in specific embodiments and applications all can change; in sum; this description should not be construed as restriction of the present utility model, is allly made any change with the utility model design philosophy, all within protection domain of the present utility model.
