Description
Technical field
The present invention relates to elevator technology fields, and in particular to a kind of permanent-magnet synchnorous gearless dragging machine.
Background technique
Ultra-thin permanent-magnet synchnorous gearless dragging machine is mounted on the guide rail in hoistway, because not occupying additionally in the height direction
Well space approved by market, the increasingly huge increasing of demand.
Under normal conditions, elevator traction machine needs to configure encoder, and encoder and traction machine rotary part carry out mechanical connect
It connects, the information that traction machine rotates is transmitted to elevator control system.An encoder is usually only arranged in traction machine in the prior art
A kind of encoder is assembled in installation position, such as only configures photoelectric encoder or magnet ring encoder.But the mounting structure of every kind of encoder
Difference, client cannot select suitable encoder to install, cause the versatility of traction machine poor, increase according to control cabinet demand
Add extra cost.And the encoder of exposed setting increases the axial dimension of traction machine, this ultra-thin machine required with traction machine
Body is runed counter to.
Conventional permanent-magnet synchnorous gearless dragging machine is radial magnetic field, and load is radial, and bearing is solely subjected to radial force.Small load-carrying
The Bearing configuration of host uses two deep groove ball bearings, for heavy-duty host, not because of deep groove ball bearing dynamic load rating
Foot, Bearing configuration use a self-aligning roller bearing and a deep groove ball bearing.Radial direction need to only be met when calculating the service life of bearing
Power.
Ultra-thin permanent-magnet synchnorous gearless dragging machine is axial magnetic field, and load is radial, because axial magnetic pull always exists and makees
For bearing, bearing must bear radial force and axial force simultaneously, and the stress of bearing is different from the Conventional permanent magnet of radial magnetic field
Synchnorous gearless dragging machine.The width of bearing is limited by traction machine axial length.
Ultra-thin permanent-magnet synchnorous gearless dragging machine currently on the market, the electromagnetic technique of axial magnetic field are gradually mature.Axis
It holds configuration and uses the in the majority of two deep groove ball bearings, there are many host of depot repair due to bearing noise is big.Other can also be used
Bearing configuration, for example, a self-aligning roller bearing and a deep groove ball bearing, self-aligning roller bearing is used to bear big radial force
And axial force, but the end-play of self-aligning roller bearing is 0.3~0.6mm, the margin of tolerance is very big, will have a direct impact on axial magnetic
The consistency of field air gap 1.5mm.
Summary of the invention
The present invention provides a kind of permanent-magnet synchnorous gearless dragging machines, and axial dimension is shorter, and smooth running, noise is small, peace
Complete reliable, versatility is good.
A kind of permanent-magnet synchnorous gearless dragging machine, including base are provided with main shaft on the base and arrange around main shaft
Stator, be equipped with around main axis and also serve as the rotor of traction sheave on the main shaft, the axial end face of rotor is equipped with and fixed
The permanent magnet that son matches is equipped with the first installation position far from one end of rotor in main shaft, is equipped with the backwards to rotor side in base
Two installation positions are equipped with the information collecting device of sense rotor movement at an at least installation position, are fixed on the rotor and information
The trigger element of acquisition device phase separation.
The trigger element and rotor rotate synchronously, and the information collecting device is used for the signal of trigger collection element, from
And obtain the rotary state information of rotor.Information collecting device and trigger element cooperate, the common function of completing encoder.
Permanent-magnet synchnorous gearless dragging machine provided by the invention, while the installation position of reserved two information collecting devices, can
To select suitable information collecting device to be installed according to the different control cabinet demands of client.
The base is fixedly connected with main shaft or base is structure as a whole with main shaft, and the base is equipped with along spindle shaft
