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 the relative side of above-mentioned yoke, at the interior friction plate that is connected with turning axle between above-mentioned armature and the above-mentioned platen and by means of wheel hub with above-mentioned armature, and for above-mentioned armature is pressed to the pressure spring that platen one side is provided with by above-mentioned interior friction plate.The present invention can simplify the structure of the magnetic clutch-break with prior art.
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 only needs electricity consumption masterpiece power source because of it, so 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 on the power transmission or braking device of common machines.
Magnetic clutch-the break of prior art constitute cited the sort of as Fig. 2.Among Fig. 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 is arranged on the opposite of coil 9, can move back and forth along the axial direction of turning axle (not having expression among the figure), 3 is platen, and this platen is relative with armature 2, be arranged on and yoke 8 axial relative sides, 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 can not be in relative rotation with being connected of wheel hub.
In addition, at the peripheral part of yoke 8, along it in some holes of being provided with of Zhou Fangxiang be embedded with pressure spring 1, this spring is pressed to platen 3 by interior friction plate 4 with armature 2, so that produce driving torque or braking torque at interior friction plate 4 places.
Platen 3 is fixed with screw 6 at some places of the circumferencial direction of yoke 8 peripheries, and is middle across gap adjustment clip 7, nut 12, and spring washer 11.
When the magnetic clutch-break with said structure used as break, yoke 8 was fixed on the suitable fixed body, can not rotate, and wheel hub 5 is connected with driven shaft.
Therefore, when not having electric current supply coil 9, armature 2 is pressed towards platen 3 one sides under the effect of pressure spring 1, in the middle of friction plate 4 is clamped in by armature 2 and platen 3 in making effectively.Braking force in that these clamp face places produce is braked axle by with the wheel hub 5 that interior friction plate 4 is connected un-rotatably braking force being passed to.And when to coil 9 power supply, armature 2 is subjected to the electromagnetic attraction effect and the active force that overcomes pressure spring 1 is drawn onto a side of yoke 8, thereby has removed the chucking power of internal friction plate 4, has just 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 installed in that wheel hub 5 then is connected with live axle on the rotating revolving meber, and its working procedure is similar substantially with situation as break.
Yet the magnetic clutch-break of prior art as shown in Figure 2 is fixed on the platen 3 because platen 3 is adjusted clip 7 by the gap, thereby exists the problem of complex structure.
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, be arranged on the coil opposite, can be along the rotating armature that axially moves back and forth, be oppositely arranged on and the axial platen of a relative side of above-mentioned yoke with above-mentioned armature, 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 for above-mentioned armature is pressed to the pressure spring that platen one side is provided with by friction plate in above-mentioned, wherein, above-mentioned skeleton is formed from a resin, be shaped on some lug bosses on it, the outer rim that this lug boss is embraced platen by ultrasound or melt process is fixed.
Advantage with magnetic clutch-break of said structure is:
1. saved in the prior art structure shown in Figure 2 and be fixed to screw required on the yoke 86, spring washer 11 and nut 12 for platen 3 is adjusted clip 7 by the gap;
2. do not need on the yoke 8 to make screw for attachment screw 6.
Below in conjunction with description of drawings the present invention:
Fig. 1 has represented the example of magnetic clutch-break of the present invention, and wherein (A) is vertical sectional view, (B) is the right elevation of (A).
Fig. 2 is vertical sectional view of the magnetic clutch of prior art.
Wherein, 21 is pressure spring, and 22 is armature, and 23 is platen, and 24 is interior friction plate, and 25 is wheel hub, and 26 is yoke, and 27 is coil, and 28 is skeleton, and 28A is a lug boss.
The following embodiment that magnetic clutch-break of the present invention is described 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 26, be installed in the coil 27 in the yoke 26 and support this coil skeleton 28, being arranged on above-mentioned coil 27 opposites can be along the armature that axially moves back and forth 22 of rotating shaft (not shown), at the interior friction plate 24 that is connected with turning axle between above-mentioned armature 22 and the above-mentioned platen 23 and by means of wheel hub 25, and for above-mentioned armature 22 is pressed to the pressure spring 21 that platen 23 1 sides are provided with by above-mentioned interior friction plate 24.
In addition, on magnetic clutch-break of the present invention, skeleton 28 is made of resin, and is shaped on some lug boss 28A on it, and the front end of this lug boss is fixed by the outer rim that ultrasound or melt process encase platen 23.
Because electromagnetic clutch of the present invention has adopted aforesaid structure, thereby has the following advantages:
(1) saved screw shown in Figure 2, spring washer, nut and gap and adjusted clip, reduced number of components, thereby can reduce cost.
(2) owing to do not need to process the screw of using with screw fit shown in Figure 2 on yoke, thereby the wall thickness of yoke outer end can do thinlyyer, and yoke can be made by pressure processing.
