Compared with the traditional elevator traction machine, the asynchronous gearless traction machine disclosed by the invention specifically has the following obvious technical characteristics that: 1, the asynchronous gearless traction machine is directly driven by adopting the three-phase asynchronous motor, and no gearbox exists; 2, the diameter of the traction wheel is small, the volume is small, the processing and the assembling are simple, the cost of raw material is reduced, and the operating cost of the elevator is reduced; and 3, compared with a permanent magnet synchronous traction machine, a control system of the asynchronous gearless traction machine is simple and the reliable, the cost is low, the maintenance is convenient, and no magnetism loss risk exists.
Description
Technical field
The present invention relates to a kind of elevator traction machine, especially a kind of directly elevator traction machine of the not acceleration and deceleration case of driving of three phase asynchronous motor that adopts.
Background technology
The most of permanent-magnet synchnorous gearless dragging machine that adopts of elevator in the market, the permanent magnet of permanent-magnet synchnorous gearless dragging machine is generally nd-fe-b, and its raw MAT'L is rare earth.Rare earth is non-renewable grand strategy resource, has greatly increased the cost of raw material of permanent-magnetic tractor.
Also have part to adopt asynchronous geared machine.Asynchronous gearless traction machine does not also have, and is because realize or say that by the relevant regulations of existing elevator national standard " GB7588-2003 " are very difficult realizing rear uses because bulky is very difficult.For be limited in elevator use in flexure stress to the adverse effect of steel rope, elevator national standard " GB7588-2003 " clear: though the number of share of stock of steel rope what, the pitch circle diameter of traction sheave should be not less than 40 with the ratio of the nominal diameter of steel rope, and the nominal diameter of steel rope is not less than 8mm.Therefore the traction sheave diameter of towing machine minimum is 320mm, and the size of traction sheave is directly proportional with the rated moment of towing machine.Also be directly proportional with its volume and the cost of raw material again.But the technology of seizing wire and little traction sheave occurred adopting abroad at present, greatly reduced the cost of elevator.Along with the development innovation of domestic elevator technology and steel rope technology, and national in the situation that all trades and professions are advocated energy-conserving and environment-protective, and the technology of towing machine also will have breakthrough.
Summary of the invention
The objective of the invention is to provide a kind of asynchronous gearless traction machine, to solve problems of the prior art.
To achieve these goals, technical scheme of the present invention is as follows:
Asynchronous gearless traction machine, it is characterized in that, comprise three phase asynchronous motor, traction sheave, coder and work the magnet stopper that limits the traction sheave rotary action, described traction sheave directly is fixed on the main shaft of three phase asynchronous motor, spiral traction groove is arranged on the traction sheave, the selected rope shape of the shape of traction groove and elevator is complementary, and described coder is connected with the main shaft of three phase asynchronous motor.
Described traction sheave is arranged on the tank tower by bearing.
In one embodiment of the invention, described tank tower is the foundry goods of integral type.Perhaps, described tank tower is the split-type structural that front and back two block plates add registration mast.
The diameter of traction sheave is that 70mm is between the 200mm.
In one embodiment of the invention, described magnet stopper is the double armature axle plate disc brake of stopping, and it is fixed on a side of tank tower.Further, the fixing opposite side of tank tower of three phase asynchronous motor.
In one embodiment of the invention, also comprise hand turning gear, this hand turning gear links to each other with the main shaft of three phase asynchronous motor.
The present invention has compared obvious technical characterstic with existing elevator traction machine, specifically has: 1. adopt three phase asynchronous motor directly to drive non-gear box; 2. the traction sheave diameter is little, and volume is little, and process and assemble is simple, has reduced the cost of raw material, has also reduced the operating cost of elevator simultaneously; 3. compare with permanent magnetic synchronous traction machine, its control system is simple and reliable, and cost is low, and is easy to maintenance, without the loss of excitation risk.
The present invention can directly replace existing permanent magnetic synchronous traction machine and asynchronous geared machine.
Characteristics of the present invention can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained to be well understood to.
