A rotor of the utility model is connected with the front end of a machine seat through a front bearing, and a stator core with a winding is arranged between the machine seat and the rotor, the stator core with the winding is fixed outside the machine seat through a screw, and the front end of the rotor is provided with a cone-shaped step, and the cone-shaped step is provided with a traction wheel, and a connecting screw is arranged between the traction wheel and the cone-shaped step, and the front end of a shaft is sleeved in the rotor, and a rear bearing is arranged between the back end of the shaft and the machine seat, and the shaft is provided with an encoder. In the utility model, the traction wheel and the rotor adopt taper fitting, and are fixed by the screw, meanwhile, the press mounting by a pressing machine is not required during assembling, and only the fixed screw is required to be disassembled during replacing the traction wheel; a front bearing room and a rear bearing room are all located at the machine seat, and the front bearing room and the rear bearing room can adopt one-time processing, and the concentricity is good, therefore, the concentricity of a front bearing and a rear bearing can be ensured after installation, and the overall performance of the main machine is improved.
Description
Technical field
The utility model relates to a kind of permanent-magnet synchnorous gearless dragging machine, belongs to the drive unit for lift technical field.
Background technology
Along with the development of modern control theory and technology and the progress of permagnetic synchronous motor designing technique, the elevator that adopts permagnetic synchronous motor to drive has obtained a large amount of practical applications with gearless machine, and permanent-magnet synchnorous gearless dragging machine finally is substituted with the asynchronous towing machine of gear has become inevitable development trend.Traction sheave is the vitals of towing machine, can produce the wearing and tearing of traction sheave because steel rope and traction sheave rub for a long time in the use of towing machine, so need to change traction sheave, towing machine needs to dismantle traction sheave sometimes when safeguarding.And the traction sheave mounting means of elevator permanent-magnetic synchnorous gearless dragging machine mostly is that traction sheave and rotor adopt the axis hole transition fit to be fixed together at present, will use special tool in the time of dismounting, this fit system is given the dismounting of traction sheave and is changed and caused very big difficulty.
Comfort level is an important indicator of elevator performance, and towing machine is as the core component of elevator, and its running stability directly influences the comfort level of elevator, and the right alignment that the towing machine front and back bearings is installed has very big influence to the stationarity of towing machine.
The towing machine front and back bearings is to be installed in respectively on the different parts at present, and the front and back bearings chamber is distributed on the different parts, can not be disposable owing to add man-hour two bearing chamber completion of processing, be difficult to the right alignment of the installation of assurance front and back bearings.And traction sheave and rotor adopt axis hole to cooperate and by screw retention, need assemble the dismounting complexity when traction sheave and rotor assembly with press; Support and rear side housing (being used for installing rear bearing) adopt split type installation, and by bolt, cause the installation right alignment of front and back bearings bad, influence bearing life, are easy to generate noise.
The utility model content
The purpose of this utility model provides a kind of new traction sheave mounting means and installation site, front and back bearings chamber, and under the prerequisite that does not influence the towing machine installation dimension, the right alignment that can make traction sheave change convenient disassembly, front and back bearings installation reaches very high precision.
The utility model comprises support, rotor, axle, rotor is connected the front end of support by front bearing, band winding stator core is set between support and rotor, outside support, the front end of described rotor is provided with type conical bench to described band winding stator core, is nested with traction sheave on described type conical bench by screw retention, between described traction sheave and the type conical bench attaching screw is set, the front end of axle is nested with in rotor, between the rear end of axle and the support rear bearing is set, and coder is installed on axle.
The utility model does not need independent rear side housing to place bearing, and traction sheave and rotor adopt taper fitting, are screwed again, does not need during assembling to press-fit with press, and the fix screw of only need dismantling when changing traction sheave gets final product; All on support, disposable processing can be adopted in the front and back bearings chamber in the front and back bearings chamber, and right alignment is fine, thereby guarantees to install the right alignment of back front and back bearings, and the overall performance of main frame promotes.
The utility model also is provided with front bearing cap at the front end face of front bearing, and described front bearing cap is by being bolted on the support.
The utility model also aft end face of rear bearing is provided with rear bearing cover, and described rear bearing cover is by being bolted on the support.
