Embodiment
This device utilizes electromagnetic clutch to power on adhesive armature, and power-off disengages the principle of armature, devises a kind of power switching device based on electromagnetic clutch, can pass through two ways input power, and load rotation with a main shaft output power drive.During electromagnetic clutch energising, armature and Moving plate adhesive, by flange input power, export to main shaft through armature and Moving plate, now, the driving motor on main shaft does not works.During electromagnetic clutch power-off, owing to armature fails and Moving plate adhesive, therefore, flange the power inputted can not be transferred to main shaft；Driving motor operations on main shaft, can directly input power to main shaft.
This device include yoke 1, Moving plate 2, armature 3, flange 4, spring leaf 5, rivet 6, a flat key 7, angular contact ball bearing to 8, spacer 9, locking nut 10, a back-up ring 11, deep groove ball bearing 12, b back-up ring 13, main shaft 14, b flat key 15, as shown in Figure 1.
With yoke 1 as matrix, deep groove ball bearing 12 is loaded in the hole of yoke 1, fix the outer ring of deep groove ball bearing 12 with a back-up ring 11；Moving plate 2 is loaded in deep groove ball bearing 12 hole, fix the inner ring of deep groove ball bearing 12, above 5 kinds of part constituent components 1 with b back-up ring 13.
Being arranged on 8 by angular contact ball bearing in flange 4 hole, spring leaf 5 is arranged in the groove of flange 4, and armature 3 utilizes rivet 6 to couple with flange 4, is fixed between the two by spring leaf 5, and a flat key 7 inserts in the keyway of flange 4, above 6 kinds of part constituent components 2.
B flat key 15 is arranged in the keyway of main shaft 14, and by the hole of two part plug-in package 1 Moving plates 2, spacer 9 is inserted in main shaft 14 from right-hand member, assembly 2 entirety is inserted in main shaft 14 from right-hand member, locking nut 10 is screwed in main shaft 14, axial restraint whole axle system from right-hand member.
The axial tab order of whole composite shaft system be successively Moving plate 2 left side against main shaft 14 shaft shoulder, Moving plate 2 left side positioning spacer 9, spacer 9 right side orientation angle contact ball bearing is to 8, finally, by locking nut 10 orientation angle contact ball bearing to 8 right sides.
After yoke 1 energising, armature 3 meeting adhesive, to Moving plate 2, flange 4 moment of torsion inputted, is transferred to main shaft 14 through armature 3, Moving plate 2 and b flat key 15；After yoke 2 power-off, relying on the elastic force of spring leaf 5 self to make armature 3 reset, owing to armature 3 fails to fit with Moving plate 2, therefore, flange 4 moment of torsion inputted is only capable of being transferred to armature 3.
Flange 4 has the keyway installing a flat key 7, a flat key 7 to be used for transmitting outside input torque to flange 4.
Flange 4 transmits moment of torsion to armature 3 by 3 uniform and rivets 6 of forward installation.
Limited by the rivet 6 of 3 uniform and reverse installations and move axially on the left of spring leaf 5.
Main shaft 14 and Moving plate 2 have keyway, be used for installing b flat key 15, the moment of torsion of Moving plate 2 is transferred to main shaft 14, drive load to rotate.
The thickness of spacer 9 needs to adjust, and is axially limiting Moving plate 2 and the angular contact ball bearing movement to 8, and is controlling the spacing about 0.5mm of Moving plate 2 and armature 3.
Angular contact ball bearing is all precision bearing to 8 and deep groove ball bearing 12, is compressed the inner ring of bearing by locking nut 10, improves the precision of axle system.
There are flange and seam in yoke 1, flange has 8 uniform unthreaded holes, for yoke is fixed on pedestal；Position when seam is used for installing.
As it is shown in figure 1, loaded by deep groove ball bearing in yoke hole, fix deep groove ball bearing outer ring with a back-up ring；Moving plate is loaded in deep groove ball bearing hole, fix deep groove ball bearing inner ring with b back-up ring, utilize this 5 kinds of part constituent components 1.During assembling, yoke flange seam is coordinated with pedestal, then with 8 uniform screws, whole assembly 1 is fixed on pedestal.
By angular contact ball bearing to being arranged in flange hole, spring leaf is arranged in the groove of flange, is coupled with flange by armature with 3 uniform rivets, is fixed between armature and flange with 3 uniform rivets by spring leaf；A flat key inserts in the keyway of flange.Above 6 kinds of part constituent components 2.
B flat key is arranged in the keyway of main shaft, and by the Moving plate hole of main shaft plug-in package 1；Spacer is inserted in main shaft from right-hand member, assembly 2 entirety is inserted in main shaft from right-hand member, locking nut is screwed in main shaft from right-hand member, axial restraint whole axle system.
A kind of based on electromagnetism reason clutch composite shaft system described in the invention also has expanded function, and the left end at main shaft can install precision bearing component, supports as axle owner, it is ensured that the wobble error of overall axle system.Axle system extension installation process is as follows:
(1) master support component is fixed on pedestal, main shaft is inserted in dead eye；
(2) b flat key is loaded in main shaft keyway, assembly 1 entirety is inserted in main shaft, and with the seam of yoke and base stand location, fasten with screw.
