Abstract
The present invention relates to a kind of magnetic clutch-break, comprise yoke, be installed in the coil in the above-mentioned yoke and be used to support this coil skeleton, being arranged on above-mentioned coil opposite can be along the armature that axially moves back and forth of turning axle, be oppositely arranged on the platen of yoke axial opposed side, at the interior friction plate that is connected with turning axle between above-mentioned armature and the platen and by means of wheel hub with armature, and presses to the pressure spring that platen one side is provided with for above-mentioned armature being clipped interior friction plate.On yoke, process the mounting hole that is used to install above-mentioned some pressure springs thereby save, can reduce cost.
Description
The present invention relates to a kind of magnetic clutch-break, specifically, what relate to is a kind of non-excited work type, it is disengagement type magnetic clutch-break after the excitation, coil in being installed in yoke is during by excitation, armature is attracted to yoke one side under the electromagnetic attraction effect, thereby make the interior friction plate that is installed between armature and the platen free to rotate, then, when coil is disengaged excitation, armature is pressed towards platen under the effect of pressure spring, friction plate can not rotate in making, thereby the turning power of making or braking force can pass to by means of on wheel hub and the turning axle that interior friction plate is connected.
Magnetic clutch-break is a power source because of it only needs the electricity consumption masterpiece, and need be such as special pressure-generating devices such as hydraulic type or pneumatic-typeds, so, except equipment such as the powerful industrial machine of needs, building machinery or vehicle, be widely used for the power transmission or the braking device of common machines.
The formation of the magnetic clutch-break of prior art is as being exemplified among Fig. 2.
As shown in Figure 2,8 is the yoke of ring-type, 9 for being contained in the coil in the yoke 8,10 for being used for the coil rack of support coils 9,2 is armature, armature be arranged on coil 9 the opposite and can axially moving back and forth along turning axle (among the figure not expression), 3 is platen, this platen and yoke 8 place the not homonymy of armature 2 respectively, 4 is interior friction plate, and it is middle with platen 3 that this friction plate is positioned at armature 2, and is connected with the turning axle (not shown) by means of wheel hub 5, wherein, friction plate is to be connected with wheel hub with relatively rotating.
In addition, at the peripheral part of yoke 8, along it in some holes of Zhou Fangxiang be embedded with pressure spring 1, this spring is used for armature 2 is pressed to platen 3 by interior friction plate 4, thereby produces driving torque or braking torque at interior friction plate 4 places.
Screw 6 is fixing with platen 3 by means of the gap adjustment clip 7 that is provided with along the some places of yoke 8 peripheries.
In addition, although in prior art constructions shown in Figure 2, pressure spring 1 is installed in several pressure spring mounting holes that are arranged at yoke 8 outer ends, and the pressure spring mounting hole also can be arranged on the inner of yoke 8.
When the magnetic clutch-break with said structure used as break, yoke 8 was fixed on the suitable fixed block un-rotatably, and wheel hub 5 is connected with driven axle.
Therefore, when not supplying with coil 9 electric currents, armature 2 is pressed towards platen 3 one sides under the effect of pressure spring 1, friction plate 4 is pressed on therebetween by armature 2 and platen 3 clampings in making effectively, produce braking force at these clamping seal face places thus, and be braked axle by braking force being passed to the wheel hub 5 that interior friction plate 4 is connected un-rotatably.And when supplying with coil 9 electric currents, armature 2 is subjected to the electromagnetic attraction effect, overcomes the active force of pressure spring 1, is drawn onto a side of yoke 8, thereby has removed the clamping impacting force of internal friction plate 4, has also promptly removed being braked the braking action of axle.
In addition, be used as at magnetic clutch-break under the situation of clutch, yoke 8 is contained in that live axle then is connected with wheel hub 5 on the rotating revolving meber, and its working procedure is similar substantially with situation as break.
Yet, magnetic clutch-the break of prior art as shown in Figure 2, outer end and the inner mounting hole that need be provided for installing pressure spring 1 and screw 6 in yoke 8, and in order to guarantee necessary magnetic force property, yoke needs certain wall thickness, brings certain difficulty so just for the pressure processing formation technique of yoke 8.
The present invention is for addressing the above problem, a kind of magnetic clutch-break is provided, comprising yoke, be installed in the coil in the above-mentioned yoke and be used to support the skeleton of this coil, being arranged on above-mentioned coil opposite also can be along the armature that axially moves back and forth of turning axle, relative with above-mentioned armature, be arranged on platen with yoke axial opposed side, the interior friction plate that between above-mentioned armature and above-mentioned platen and by means of wheel hub, is connected with turning axle, and be above-mentioned armature to be clipped above-mentioned interior friction plate press to the pressure spring that platen one side is provided with, wherein, inner peripheral surface at above-mentioned skeleton is provided with the hole that several are used to install pressure spring, and some pressure springs promptly are installed in respectively in above-mentioned each mounting hole.
Non-excited work type brake with said structure has following characteristics with respect to existing structure shown in Figure 2:
1. do not need to process a plurality of mounting holes that are used to install pressure spring;
2. the outer end of yoke and inner wall thickness select to satisfy the MIN size of magnetic circuit characteristic get final product, promptly can be quite thin, be shaped thereby cutting yoke in the past can be changed into pressure processing.
Below in conjunction with accompanying drawing the present invention is described.
Fig. 1 is expression magnetic clutch of the present invention-break embodiment's longitudinal sectional view;
Fig. 2 is existing magnetic clutch longitudinal sectional view.
Wherein, 11 is pressure spring, and 12 is armature, and 13 is platen, and 14 is interior friction plate, and 15 is wheel hub, and 16 is screw, and 17 are gap adjustment clip, and 18 is yoke, and 19 is coil, and 20 is coil rack, and 21 is the pressure spring mounting hole.
The embodiment of magnetic clutch-break of the present invention is described hereinafter with reference to Fig. 1.
The basic comprising of this magnetic clutch-break is identical with the magnetic clutch-break of prior art shown in Figure 2.As shown in Figure 1, comprising yoke 18, be installed in the coil 19 in the yoke 18 and support skeleton 20, the armature 12 of this coil, this armature is arranged on coil 19 opposites, can along axially the moving back and forth of turning axle (not shown), 12 relative with armature, be arranged on axially with the platen 13 of yoke 18 opposite sides, between above-mentioned armature 12 and the above-mentioned platen 13 and the interior friction plate 14 that is connected with turning axle by means of wheel hub 15 and for above-mentioned armature 12 is clipped above-mentioned in friction plate 14 press to the pressure spring 11 that platen 13 1 sides are provided with.
And magnetic clutch-break of the present invention is provided with the hole 21 that several are used to install pressure spring at the inner peripheral surface place of above-mentioned skeleton 20, and some pressure springs 11 promptly are installed in respectively in above-mentioned each mounting hole 21.
Because electromagnetic clutch of the present invention has adopted aforesaid structure, thereby has the following advantages:
1. owing to do not need to process installing hole be used to a plurality of Compress Springs are installed, thereby can reduce cost.
2. the outer end of yoke and inner wall thickness are selected to satisfy the MIN size of Magnetic circuit characters and get final product, and wall thickness can be quite thin, thereby machining yoke in the past can be changed into the pressure processing shaping, to reduce significantly cost and weight reduction.
