Description
Technical field
The utility model belongs to elevator corollary apparatus technical field, is specifically related to a kind of elevator permanent magnet synchronous traction machine with outer rotor.
Background technology
Permanent-magnetic synchronous tractor for elevator drum brake electromagnet outward appearance is generally cylindrical, is fixed on the top of motor bed-plate.Mainly contain two kinds of modes at present.
First kind of way is connected by middle fixed base plate, middle fixing plate is drilled with 4 screwed holes for being fastenedly connected with motor bed-plate, what have is also drilled with 2 pin-and-holes that can accurately locate, middle fixing plate also needs process the one section circular arc identical with drum brake electromagnet external diameter, the middle part of circular arc is processed with the through hole be connected with drum brake electromagnet middle part, via count is 4, by bolt be distributed in drum brake electromagnet cylindrical upper screwed hole and be connected and locate.
The second way adopts less middle fixing plate, one end of fixed head is plane, another plane is processed with concave arc in a section identical with drum brake electromagnet external diameter, fixed head is drilled with 4 through holes, the groove that motor bed-plate processing one is identical with middle fixing plate plane sizes, groove-bottom plane is drilled with 4 through holes.First fixed head is embedded motor bed-plate during installation, by bolt be distributed in drum brake electromagnet cylindrical upper screwed hole and be connected and locate.
The shortcoming of first kind of way is that middle fixing plate is comparatively large, and many with material, processing capacity is large, and cost is high, and assembly cost also can increase, and drum brake electromagnet positioning precision is not high. add the workload of adjustment.
The shortcoming of the second way is that motor bed-plate top needs Milling Machining groove, milling Pocket Machining efficiency is low, increase support processing cost, middle fixing plate size is little, also less for concaved circular cambered surface in location fit, coordinate with it the drum brake electromagnet outer round surface of contact also less, easily cause the stability of brake electromagnet bad, brake troubles increases.
The through hole pitch-row for fixing brake electromagnet that above-mentioned two kinds of modes are processed on middle fixing plate is all less than 50 ㎜, and brake electromagnet easily loosens.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides the electromagnet accurate positioning of brake, a kind of elevator permanent magnet synchronous traction machine with outer rotor of fixation.
In order to realize the utility model object, by the following technical solutions:
A kind of elevator permanent magnet synchronous traction machine with outer rotor, comprise drum brake, motor bed-plate, stator core, rotor yoke and be fixed on the multiple permanent magnets inside rotor yoke, described drum brake comprises drum brake electromagnet, described drum brake electromagnet is positioned at the top of motor bed-plate, motor bed-plate top be processed with identical with drum brake electromagnet external diameter in concaved circular cambered surface.
As preferably, described interior concaved circular cambered surface has two at least, recessed and one-body molded with interior concaved circular cambered surface between described interior concaved circular cambered surface;
Further preferably, described interior concaved circular cambered surface is two; Again further preferably, be respectively equipped with corresponding through hole and screwed hole bottom the cylindrical of described interior concaved circular cambered surface and drum brake electromagnet, be bolted interior concaved circular cambered surface and drum brake electromagnet; Again further preferably, the distance between described through hole is 150-200mm.
As preferably, the outer end of the interior concaved circular cambered surface at described two ends is fixed with limiting component; Further preferably, described limiting component is the catch exceeding interior concaved circular cambered surface extreme lower position.
In sum, the beneficial effects of the utility model are:
A kind of elevator permanent magnet synchronous traction machine with outer rotor described in the utility model, drum brake is positioned at the top of motor bed-plate, motor bed-plate top be processed with identical with drum brake electromagnet external diameter in concaved circular cambered surface, to be coordinated with drum brake electromagnet by interior concaved circular cambered surface and contact, accurate positioning, and do not need middle fixing plate and drum brake electromagnet and the reliable stationary device of motor bed-plate can be ensured.
Further, motor bed-plate is provided with for concaved circular cambered surface in coordinate with the cylindrical of drum brake electromagnet more than two sections, one through hole is arranged at the bottom being positioned at the arc surface at two ends, also two corresponding screwed holes are drilled with bottom drum brake electromagnet cylindrical, pitch-row is consistent with above-mentioned motor bed-plate pitch-row is 150-200mm, drum brake electromagnet and motor bed-plate is fastenedly connected during installation respectively by 2 bolts.Traditional fixes with fixed head, pitch-row is less than 50mm, the utility model is compared with conventional method, pitch-row between motor bed-plate arc surface significantly increases, stability during brake operation is greatly increased, greatly reduce because fastening bolt loosens the risk making misfunctioning of brake, extend the useful life of brake.
Or further, the outer end of the interior concaved circular cambered surface at two ends is provided with limiting component, and limit stop electromagnet slides axially along motor bed-plate arc surface.
