Abstract
A method of forming a silicon oxide film (11) on a glass substrate surface (10) by a low temperature chemical vapor deposition process using trialkoxysilane and ozone, thereby smoothing said surface.
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 magnetic clutch one 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 the internal friction sheet, and it is middle with platen 3 that this internal friction sheet is positioned at armature 2, and is connected with the turning axle (not shown) by means of wheel hub 5, wherein, being connected between wearing piece and wheel hub is not relatively turnable connection.
In addition, the some holes that distribute in the outer periphery week near yoke 8 are embedded with pressure spring 1, and this spring is used for armature 2 is pressed to platen 3 by internal friction sheet 4, thereby produces driving torque or braking torque at internal friction sheet 4 places.
Screw 6 is fixed 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, internal friction sheet 4 is pressed on therebetween by armature 2 and platen 3 clampings, 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 internal friction sheet 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 wearing piece 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 object of the present invention is to provide a kind of improved magnetic clutch-break to solve above-mentioned problems of the prior art.
Magnetic clutch-break of the present invention comprises 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, be oppositely arranged on platen with yoke axial opposed side with above-mentioned armature, the internal friction sheet that between above-mentioned armature and above-mentioned platen and by means of wheel hub, is connected with turning axle, and press to the pressure spring that platen one side circumferentially is provided with for above-mentioned armature being clipped above-mentioned internal friction sheet, wherein, be provided with the hole that several are used to install pressure spring near above-mentioned skeleton inner peripheral surface place, some pressure springs then are installed in respectively in above-mentioned each mounting hole.
Non-excited work type brake with said structure has following characteristics with respect to prior art constructions 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 are selected to satisfy the MIN size of magnetic circuit characteristic and get final product, promptly can be quite thin, thus cutting yoke in the past can be used instead the pressure processing shaping.
3. overcome the problem that is difficult to shape that exists in the prior art, it is comparatively simple that its pressure processing is shaped.
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 the longitudinal sectional view of existing magnetic clutch.
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 be 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 close 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.
