Description

Gearless permanent-magnet synchronous traction machine
Technical field
The present invention relates to elevator traction machine, relate in particular to a kind of low speed high torque and gearless permanent-magnet synchronous traction machine with hand-barring.
Background technology
Along with the development need of modern architecture industry, elevator except that having proposed low noise, efficient, reliability, is also required small room or do not have the structure of machine room formula.
In the prior art, application number as shown in Figure 2 is 01113256.6, name is called the structural representation of " directly driving synchronous dragger with Nd-Fe-B permanent magnetic rotor ", and Fig. 3 is the end view of Fig. 2, and this traction machine adopts multipole outer-rotor structure and two layers of annular stator structure; The yoke 02 of external rotor 01 is both as the magnetic circuit that is configured to motor of salient pole magnet steel 03, also as the fixed support of traction sheave 04; Internal stator is made up of stator inner loop 05, stator core 07, armature winding 06 and stator outer shroud 09; Traction sheave 04 is fixed on the external rotor 01, stator and rotor support by bearing 08, adopt fabricated construction between stator inner loop 05 and the stator outer shroud 09, be fixed with brake arm 010 on the stator outer shroud 09, between brake arm 010 and the external rotor 01 brake strip 017 is arranged as braked wheel, electromagnet 014, compression spring 015 and screw rod 016 are installed in the top of stator outer shroud 09, brake arm 010 is installed in the moving fulcrum place of both sides, stator outer shroud 09 lower end, compression spring 015 is connected with brake arm 010, on the little axle 011 of motor photoelectric encoder is installed; The salient pole magnet steel 03 that external rotor 01 inner surface mounts adopts high performance Nd-Fe-Bo permanent magnet material; Armature winding 06 adopts the fractional slot winding structure; Stator core 07 adopts flume structure; The aperture of opening on the external rotor 01 012 both can be used as the water flowing heat transmission, can be used as the point of application of dependent manual operation elevator when sudden power again.Advantages such as though said structure is compact, torque is big, loss is little, noise is low, vibration is little, promote steadily and flat bed is accurate, but there is following defective in the structure of this traction machine: traction sheave need be pulled down rotor when changeing in the lump, then causes between stator and the rotor air gap inhomogeneous easily; Inner sealing formula Bearing Installation not only can't finely lubricate and reduce useful life again; This enclosed construction also is unfavorable for motor radiating.
The objective of the invention is to overcome the deficiency of prior art, be convenient to maintain, the open gearless permanent-magnet synchronous traction machine that releasably connects as one with hand-barring and provide a kind of.
Summary of the invention
Structure of the present invention comprise adopt key be set in main shaft in the bowl-type external rotor of free cylinder is arranged, the outer surface of external rotor is fixed a traction sheave, external rotor the rim of a bowl place is provided with braking surface, the cylindrical of the void column body of external rotor and bearing set and be swallow shape successively, and the crooked backward endoporus that constitutes the open annular groove of wing has the stator of flange, pack into successively in the cannelure of stator the stator armature iron core that is wound with stator winding and permanent-magnet steel and with the yoke of external rotor bowl-type edge butt joint, the bowl edge of bowl is connected in the stator inner hole flange and bowl bottom orifice connection bearing and main shaft successively at the bottom of the hole, main shaft from the external rotor link to the hole at the bottom of bowl stretch out and at the bottom of near the hole bowl suit one encoder, be parallel in the void column body of main shaft and be provided with the tank filler sleeve that communicates with bearing.
The present invention adopts open external rotor to be connected for the stator in hole with the inboard and is loaded on main shaft by bearing holder (housing, cover), and assembly precision of this structure is accurate, does not need dismounting when maintenance, has guaranteed that air gap is even between external rotor and the stator; One tank filler sleeve that leads in bearing is arranged, so that the intermittent oiling bearing is guaranteed the bearing good lubrication on the external rotor; Owing to adopt Open architecture, make the complete machine thermal diffusivity good; Traction sheave is loaded on the external rotor outer surface, and its compact conformation, volume are little; Main shaft stretches out and locates to connect the hand-barring of any structure, so not only keep in repair safety, and structure of the present invention is applicable to the installation of small room or machine-roomless lift.
