Description

Elevator traction machine
Technical field
The present invention relates to elevator traction machine, especially a kind of elevator traction machine that embeds the transmission of built-in planetary wheel permagnetic synchronous motor.
Background technology
Elevator traction machine is installed in the elevator(lift) machine room or access to elevators of skyscraper, and the elevator traction machine that slows down by mechanical drive in the prior art is broadly divided into the towing machine of worm and gear deceleration transmission and the towing machine two big classes that the gear reduction transmission is slowed down.The common elevator traction machine that epicyclic gear transmission is arranged in the elevator traction machine that the gear reduction transmission is slowed down.Planetary wheel towing machine in the known technology has the two-stage planetary gear speed reducing mechanism, input speed is all at 960r/pm-1500r/pm, even it is higher, its drive motor is followed the single speed frequency-adjustable speed-adjustable motor of conventional worm worm gear towing machine configuration fully, owing to have the transmission of high-speed planetary gear, so the planetary wheel towing machine all has bigger gear mesh noise.
Summary of the invention
The objective of the invention is to provide a kind of epicyclic gear transmission elevator traction machine of novel structure, this novel planetary gear transmission towing machine novel structure, compactness,, efficient high and low noise little, low vibrations from heavy and light, volume to market.Particularly, the present invention is under the driving mechanism of the epicyclic gear transmission towing machine that is different from known technology, with the big torque motor configuration of middle and slow speed of revolution single-stage planetary reduction gear apparatus with 300r/pm-600r/pm, structurally carry out technical combination, realize a kind of elevator traction machine with planetary wheel permagnetic synchronous motor transmission of hightech level.
In order to achieve the above object, the present invention adopts following scheme to realize:
At first, planetary reduction gear of the present invention adopts the structural principle of NGW type planetary reduction gear, between middle input shaft (sun wheel shaft) and the drive motor axle is that key is connected, the electrical motor of epicyclic reduction gear configuration is not 2 grades that the planet towing machine is disposed in the known technology, 4 grades, 6 grades of motors, but because adopted single-stage planetary gear towing machine, according to the speed ratio principle of single-stage planetary gear reduction ratio less than 13: 1, for towed elevator provides specified biography speed and rated load torque, therefore designed a kind of middle low speed permanent magnet synchronous motor (perhaps asynchronous dynamo), this motor has different capacity, different rotating speeds, different torques, its specification series is divided into simple several levels.Its range of speed is 250r/pm to 600r/pm, utilizes above-mentioned single-stage planetary retarder just can production assembly speed be 2.5m/s to 0.5m/s, and load is the various towing machines of 300kg to 5000kg, thereby has satisfied the operating needs of towed elevator.

The specific embodiment
As shown in Figure 1,, alleviate deadweight, shorten the towing machine axial dimension, the gear box casing 2 of epicyclic reduction gear is directly docked with drive motor support 4 preceding seams, and cantilever support is on electric machine stand 4 for simplified structure.Gear box casing 2, carrying main bearing 10, output shaft combined sealed cap 9, planetary wheel carrier main shaft 13, oblique internally toothed annulus 3, compound planet gear 18, solar shaft gear 17, seal cover cap 19 behind the gear case, reach the sealing gear train assembly that one of formations such as making up long-lived sealing 32 is marked with lubricating oil, the notable attribute of this new type speed reducer is, gear box casing 2 is stair-stepping cylindrical box, its most of volume particularly embedding to size than major axis of postmedian is built in the electric machine stand 4, carrying main bearing 10, seal cover cap 19 has stretched in the inner space of p-m rotor 7 behind long-lived sealing 32 of combination and the gear case, motor front bearing 8 is placed in the rear end of gear box casing 2, becomes the bearing seat of motor front bearing 8.
It is two-layer that characteristics of the present invention are that also the inside of p-m rotor 7 is that hollow, voided layer body has, and the external hollow layer can hold the bearing seat that motor front bearing 8 and gear box casing 2 rear ends constitute, and interior voided layer is placed solar shaft gear 17 and the long-lived sealing 32 of combination.
In order to transmit motor torque, in the hollow axis body in the rear end of p-m rotor 7, also be equipped with four and connect toothed disc 28, take turns the footpath inner space to drag wheel 33 this section axial dimensions and by brake wheel 33: gathered towing machine drag mechanism, the artificial disc mechanism of car, the signal detection feedback mechanism, above-mentioned three members are with respect to machine bed, and in service at elevator is rotor, and it is covered by the jigger wheel bonnet.
Make a general survey of the unit design and the inherent mechanism of towing machine, have novel, simple in structure, assembling easily, plurality of advantages such as little, the safe in operation of perfect in shape and function,, stable drive low, noise from heavy and light, volume compact, rotating speed.
