Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of coal-winning machine Motor torque axle overload protection arrangement based on magnetic converting technique of the utility model, comprise cutting units gear 3, be arranged on the bearing 2 at cutting units gear 3 two ends, shaft coupling 4, cutting units housing 6 and motor 8, also comprise torque axis II 1, torque axis I 7 and magnetic flow liquid overload protection arrangement 5; Described torque axis II 1 one end and cutting units gear 3 spline joint, the other end is connected with magnetic flow liquid overload protection arrangement 5 by shaft coupling 4; Rotor 9 spline joint of described torque axis I 7 one end and motor 8, the other end is connected with magnetic flow liquid overload protection arrangement 5 by shaft coupling 4; Described magnetic flow liquid overload protection arrangement 5 is fixed on cutting units housing 6 by connector 13.
As shown in Figure 2, as first preferred version of the utility model to such scheme, described magnetic flow liquid overload protection arrangement 5 is primarily of housing, and output shaft 10, bearing pedestal 12, power rotor 15, driven rotor I 18, driven rotor II 19, power shaft 22 form, described housing is made up of left shell 14 and right shell body 17, described bearing pedestal 12 is fixed on a left side by connector 13, right shell body 14, on 17, described output shaft 10 and power shaft 22 run through left respectively, right shell body 14, 17, and the output shaft 10 be positioned at outside housing and power shaft 22 part are arranged on bearing pedestal 12 respectively by bearing 2, it is middle with driven rotor II 19 that described power rotor 15 is placed in driven rotor I 18, certain power rotor 15 also can be placed in any position between two driven rotors, but be positioned at centre position, magnetic field better effects if, described power rotor 15 and driven rotor I 18, the magnetic flow liquid working clearance is left between driven rotor II 19, described power rotor 15 links together with power shaft 22, and driven rotor I 18 and output shaft 10 link together, and described driven rotor II 19 is fixed together by connector 13 and driven rotor I 18,
Described housing is also provided with permanent magnet 16, described permanent magnet 16 is positioned at position, middle, driven rotor about I 18 both sides, the magnetic field that described permanent magnet 16 produces, arrives this by left and right housing 14,17, and the working interface between two housings forms the magnetic field perpendicular to housing side.
Technique scheme, runs at torque axis overload main driven rotor short time slippage, plays a protective role, recover synchronous operation, effectively protect torque axis under normal condition, extend the useful life of torque axis.In addition, the utility model, for the ease of installing this overload protection arrangement, has been made an independently structure, is fixed by housing and shearer's shell 6.
As the improvement of the utility model to technique scheme, between described driven rotor II 19 and power shaft 22, be provided with oil sealing 21, effectively prevent magnetic flow liquid and reveal, the safety and reliability of the equipment that further ensures in running.
As the utility model to technique scheme second preferred version, the magnetic flow liquid working clearance of described magnetic flow liquid overload protection arrangement 5 is 1mm ~ 3mm, when actual selecting; staff can need to select 1mm according to scene; 2mm or 3mm, certainly, also can choose the arbitrary numerical value of 1mm ~ 3mm.Working clearance is time too small, require that the machining accuracy of driving disc spacing pressing is high and assembly difficulty is large, also can reduce the mobility of magnetic flow liquid simultaneously, working clearance, time larger, can cause again magnetic circuit reluctance to increase, and magnetic field intensity declines, the moment of torsion transmitted also can decline, therefore choosing the working clearance is that 1mm-3mm is the most suitable, both not high to the requirement on machining accuracy of driving disc spacing pressing, and magnetic field intensity can not be caused again to decline.
As the utility model to technique scheme the 3rd preferred version, described power rotor 15 all adopts the mode of welding to link together with power shaft 22, driven rotor I 18 with output shaft 10, steadiness is better, not easily loosen or damage, effectively ensure that the operating reliability of equipment further.
