Description
Technical field
The invention belongs to elevator technology fields, are related to a kind of permanent magnetism elevator traction machine, especially a kind of light permanent-magnetic elevator
Traction machine.
Background technique
Permanent magnetism elevator traction machine is rapidly developed in recent years because of its energy-efficient feature；But this permanent magnetism elevator drags
Draw and be typically provided with oil filling oil nozzle in machine, periodically to fill lubricating oil to bearing, to maintain in permanent magnetism elevator traction machine
The good lubrication state of bearing；On the other hand in this kind of traction machine be equipped with forward and backward two bearings and traction sheave, traction sheave with before,
The setting of rear bearing is in that cantilever design, both traction sheave and forward and backward bearing are that sequence arranges；After having stator mounting disc and traction machine again
Bearing axis split settings；These three situations are with the presence of following defect:
1, the period for filling lubricating oil is shorter, frequent operation；Since position of bearings is between rotor and stator, filling profit
Due to fuel-flow control inaccuracy when lubricating oil, there is lubricating oil because overflowing after filling it up with often, so that being directed at lubricating oil flow to stator coil
On, and then the insulating layer on coil is destroyed, generate traction machine burning damage accident.
2, traction sheave and forward and backward bearing sequence are arranged, and this set is disadvantageous in that the pressure of fore bearing is
The sum of traction sheave and the pressure of rear bearing, pressure is larger, and rear bearing will also bear biggish power, therefore antero posterior axis
The model held is larger, and purchase cost is higher.
3, for the stress of rear bearing axis compared with fore bearing, stress is smaller, and retaining element rises fixed to stator mounting disc and thereon
In addition position effect, therefore, rear bearing axis and rotor mounting disc split settings are also manufactured using the higher high-quality steel of intensity, at
This increase is more.
