Embodiment
The embodiments described below with reference to the accompanying drawings are exemplary, is only used for explaining the present invention, and can not be construed to
Limitation of the present invention.
Embodiments of the invention：As shown in figure 1, a kind of cup, diff. side bearing dismounting accessory, including positioning sleeve 1, drag hook
Set 2, tapered sleeve 3 and drag hook 4, the center of the drag hook set 2 are provided with screw rod installation portion 12, grafting in the screw rod installation portion 12
Swivel nut 22 is fixed with, the end of the swivel nut 22 is provided with limiting stand 23, and the end face of the limiting stand 23 and drag hook set 2 offsets
Connect；The screw rod 7 is spirally connected with the swivel nut 22.The drag hook 4 is two, is symmetricly set in the drag hook set 2, the drag hook
4 middle part is rotatablely connected by one end of straight pin 8 and drag hook set 2, and one end of the positioning sleeve 1 and the screw rod 7 turns
Dynamic connection, the positioning sleeve 1 are provided with 2 through holes 9, on the drag hook 4 one end with hook 14 through after the through hole 9 simultaneously
The positioning sleeve 1 is stretched out, spring catch 10 is installed on the lateral surface of the other end, medial surface is installed by spring 11 and the screw rod
The outer wall connection in portion 12, the tapered sleeve 3 are socketed on the drag hook set 2, and the inwall of the tapered sleeve 3 is provided with reducing groove 13,
The spring catch 10 is connected in the reducing groove 13.
Specifically, position of the tapered sleeve 3 on drag hook set 2 is first adjusted during use, the spring catch 10 on drag hook 4 is slipped into reducing
Deeper position (i.e. the larger position of the interior diameter of reducing groove 13) in groove 13,2 drag hooks 4 carry in the presence of spring 11
One end of hook 14 rotates to the direction drawn close；Then hook 14 is inserted in cup, diff. side bearing, and positioning sleeve 1 is aligned
The end face of housing and then tight with hand pressure, it will be appreciated by persons skilled in the art that in order that cup, diff. side bearing can be by
Smoothly extract, the diameter of positioning sleeve 1 is naturally larger than the external diameter of cup, diff. side bearing, then adjusts the position of tapered sleeve 3, makes spring
Pin 10 slips into position shallower in reducing groove 13 (i.e. the less position of the interior diameter of reducing groove 13), the push the spring pin of tapered sleeve 3
10 simultaneously compression spring 11, the hook 14 of the other end of drag hook 4 rotated to close to the direction of cup, diff. side bearing inwall, until card
Enter in the gap between cup, diff. side bearing and housing, then using the instrument such as spanner rotary screw 7, because screw rod 7 is with determining
Position set 1 is rotation connection, and relative motion will not be produced between positioning sleeve 1 and housing, described logical with it under the rotation of screw rod 7
Crossing the drag hook set 2 of screw thread cooperation can move to the direction of remotely located set 1, be transported while drag hook 2 motion of set with drag hook 14
It is dynamic, because drag hook 14 has caught on cup, diff. side bearing, so can be same with cup, diff. side bearing while drag hook 14 moves
Shi Yundong, cup, diff. side bearing is pulled out into housing so as to realize.
One kind is preferably carried out mode, as shown in figure 3, having the first inclined-plane 5 and the second inclined-plane in the reducing groove 13
6, the angle a between first inclined-plane 5 and horizontal plane is 30 degree, and the angle b between second inclined-plane 6 and horizontal plane is 8
Degree.When spring catch 10 moves to 30 ° of angles with 8 ° of angle tie point positions, contacted for hook 14 with cup, diff. side bearing inwall
It is in order that linking up with 14 entrance differential mechanisms that can be gently that angle b between the second inclined-plane of critical point 6 and horizontal plane, which selects 8 ° of angles,
Bearing outer ring takes out out of cup, diff. side bearing, avoids damaging cup, diff. side bearing, first inclined-plane 5 and horizontal plane
Between angle a select 30 ° of angles, spring catch 10 can be made along the quick sliding of the first inclined-plane 5 to correct position, improve work effect
Rate.It will be appreciated by persons skilled in the art that the best angle of the inclined-plane 6 of the first inclined-plane 5 and second and horizontal plane is not
It is unique, its best angle needs to be determined according to specific cup, diff. side bearing size.
In order to more smoothly split out cup, diff. side bearing from housing, above-mentioned drag hook covers 2 in addition to using 2,
It may be arranged as 4 or 6 or 8, the quantity of drag hook 4 sets more, and unloading process is more steady, but is the shortcomings that bring
Assistant tool structure is more complicated, and manufacturing cost is higher.
In order to ensure that screw rod 7 can swimmingly rotate on positioning sleeve 1 in use, it is preferable that the positioning sleeve 1 includes fixed
Position portion 16 and installation portion 17, the location division 16 are integral type structure with the installation portion 17, and the location division 16 is located at described
Side of the installation portion 17 away from drag hook set 2,2 through holes 9 are on the installation portion 17, in the installation portion 17
Heart position is provided with stepped hole 18, is provided with thrust bearing 15 in the stepped hole 18, and one end of the screw rod 7 sequentially passes through described
Positioned after thrust bearing 15 and stepped hole 18 by the first snap ring 19.The stepped hole 18 is arranged on to the centre bit of installation portion 17
Put, after screw rod 7 loads in stepped hole 18, the axle center of positioning sleeve 1 and the axle center of drag hook set 2 can be made collinear, so rotated
When screw rod 7, the uniform stressed of positioning sleeve 1 can be made, will not be caused during cup, diff. side bearing is pulled out housing and
The damage of bearing outer ring, the quality of effective parts.
Further, as depicted in figs. 1 and 2, the drag hook, which is covered on the outer wall of 2 one end, has positive stop lug boss 24, the other end
Outer wall is provided with snap ring mounting groove 20, and the second snap ring 21 is provided with the snap ring mounting groove 20, and the tapered sleeve 3 is located at the limit
Between position boss 24 and second snap ring 21.By the setting of the snap ring 21 of positive stop lug boss 24 and second, on the one hand it is easy to cone
The progress of set 3 is spacing, on the other hand makes it easy to dismount.
Construction, feature and the action effect of the present invention, above institute is described in detail according to the embodiment shown in schema above
Only presently preferred embodiments of the present invention is stated, but the present invention is not to limit practical range shown in drawing, it is every according to structure of the invention
Want made change, or be revised as the equivalent embodiment of equivalent variations, when still without departing from specification and illustrating covered spirit,
All should be within the scope of the present invention.
