A kind of overload clutch with locking protection mechanism, specific embodiment are as follows:
As shown in figure 15, when assembly, the central axis along transition axis 1 successively assembles all parts, and transition axis 1 is used
Fixing bearing 2 is fixed on fixed frame (structures such as fixed frame and bolt are omited herein), is then sequentially loaded into fixation along axial direction
Bearing 2, spacer 3, thrust ball bearing 4, clutch output chain gear 5, the first tooth pad 6, the second tooth pad 7, drive sleeve 8, wherein assembling
When part drive sleeve 8, it is desirable that with threaded hole 802 key teeth is aligned with the key teeth with blind hole 108 on transition axis 1 in drive sleeve 8, will be passed
Dynamic 8 loading transition axis 1 of set then passes through the threaded hole in drive sleeve 8 so that threaded hole 802 and 108 center of blind hole are first aligned
802 are put into second spring 1202 in the blind hole 108 on transition axis 1, then mandril 1204 are fitted into thread bush 1203, two
Lubricating grease is smeared in circular groove 1207 after person's assembly, locking steel ball 1201 is adhered to the circular groove for filling lubricating grease
In 1207, thread bush 1203 is then screwed in into the threaded hole 802 in part drive sleeve 8 with mandril 1204 and locking steel ball 1201
In, 1/3 circle is retracted after being screwed to bottom, avoids 802 end face of thread bush from directly contacting the key teeth surface of transition axis 1, at this time locking steel
Ball 1201 should be just pressed in second spring 1202, be carried on the back thread bush 1203 tightly using clamp nut 1205；Later, the first spring
9, spring cup 10, fastening nut 11 are sequentially loaded into, using the reduction length of 1 11 the first spring of adjustment part 9 of fastening nut to 115
Then ± 2mm assembles another 1 fastening nut 11, two fastening nuts back is tight, and drive sleeve 8 is pressurized at this time, but due to locking steel ball
1201 at this time locking drive sleeve 8 it is mobile, cause the first tooth pad 6 and the second tooth pad 7 that can not be engaged, as shown in Figure 3-4, at this time must
Mandril 1204 is gently tapped using "painted-face" character in opera, is pushed into locking steel ball 1201 on transition axis 1 in blind hole 108 by mandril 1204, it is axial
Locking releases, and drive sleeve 8 and the second tooth pad 7 are engaged with the first tooth pad 6 rapidly under 9 pressure of the first spring, package unit assembly
It finishes, as shown in Figs. 1-2.
After assembly, 8 upper screwed hole of drive sleeve, 802 central axis is just staggered with 108 central axis of blind hole on transition axis 1
6.5mm must check mandril 1204 whether in loosening state, without by any clamping stagnation manually at this time.
State when the utility model clutch works normally is as shown in Figs. 1-2, and power device drives transition axis 1 to rotate,
Transition axis 1 drives drive sleeve 8 to rotate, and drive sleeve drives the rotation of the second tooth pad 7, and the second tooth pad 7 drives the rotation of the first tooth pad 6, the
One tooth pad 6 drives clutch output chain gear 5 to rotate, and clutch output chain gear 5 connect with power output device and completes power
Output；When output overloading, power output stops, and clutch output chain gear 5 and the first tooth pad 6 stop operating, therefore the first tooth
It skidding between pad 6 and the second tooth pad 7, the second tooth pad 7 drives drive sleeve 8 that the pressure of the first spring of part 9 is overcome to move axially,
The first time side set that the second tooth pad 7 and the first tooth pad 6 occurs, since tooth pads drive sleeve 8 when tooth height is just 6.5mm, i.e. side set
And second tooth pad 7 move axially 6.5mm, therefore while side set part locking steel ball 1201 second spring 1202 promotion under bullet
Out, it is caught in the circular groove 1207 of thread bush 1203, that is, is stuck between drive sleeve 8 and transition axis 1, first spring 9 of locking
Drive sleeve 8 and the second tooth is pushed to pad 7 back pressure, two tooth pads are in and mutually stagger state and can not continue to be engaged at this time, cause to input
While operating, output end shuts down, as shown in Figure 3-4 at end；After output end overload releases, the first tooth pad of clutch is needed
6 and the second tooth pad 7 when restoring occlusion, "painted-face" character in opera is used only at this time and gently taps mandril 1204, by mandril 1204 by locking steel ball
1201 are pushed into again in the blind hole 108 on transition axis 1, release the clamping stagnation of locking steel ball 1201, then under 9 pressure of the first spring,
Drive sleeve 8 and the second tooth pad 7 returns, restore occlusion.
