Detailed description of the invention
The embodiment described below with reference to accompanying drawing is 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 it is 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 described drag hook set 2 is provided with screw rod installation portion 12, grafting in described screw rod installation portion 12
Being fixed with swivel nut 22, the end of described swivel nut 22 is provided with limiting stand 23, and described limiting stand 23 offsets with the end face of described drag hook set 2
Connect；Described screw rod 7 is spirally connected with described swivel nut 22.Described drag hook 4 is two, is symmetricly set in described drag hook set 2, described drag hook
The middle part of 4 is rotationally connected by one end of straight pin 8 with described drag hook set 2, and described positioning sleeve 1 turns with one end of described screw rod 7
Being dynamically connected, described positioning sleeve 1 is provided with 2 through holes 9, on described drag hook 4 with hook 14 one end through after described through hole 9 also
Stretching out described positioning sleeve 1, the lateral surface of the other end is provided with spring catch 10, medial surface is installed with described screw rod by spring 11
The outer wall in portion 12 connects, and described tapered sleeve 3 is socketed on described drag hook set 2, and the inwall of described tapered sleeve 3 is provided with reducing groove 13,
Described spring catch 10 is connected in described reducing groove 13.
Specifically, first regulate the tapered sleeve 3 position on drag hook set 2 during use, make the spring catch 10 on drag hook 4 slip into reducing
Position (position that i.e. reducing groove 13 interior diameter is bigger) deeper in groove 13, under the effect of spring 11 2 drag hooks 4 with
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 directed at
The end face of housing is then tight by hand pressure, it will be appreciated by persons skilled in the art that in order to enable cup, diff. side bearing by
Extracting smoothly, the diameter of positioning sleeve 1 is naturally larger than the external diameter of cup, diff. side bearing, then regulates the position of tapered sleeve 3, makes spring
The position (position that i.e. reducing groove 13 interior diameter is less) that pin 10 is shallower in slipping into reducing groove 13, tapered sleeve 3 promotes spring catch
Compression spring 11 while of 10, the hook 14 of drag hook 4 other end rotates near the direction of cup, diff. side bearing inwall, until card
Enter in the gap between cup, diff. side bearing and housing, then use the instrument rotary screws 7 such as spanner, owing to screw rod 7 is with fixed
Position set 1 is for being rotationally connected, and will not produce relative motion between positioning sleeve 1 and housing, described logical with it under the rotation of screw rod 7
The drag hook set 2 crossing threaded engagement can move to the direction of remotely located set 1, transports with drag hook 14 while drag hook set 2 motion
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, thus realize cup, diff. side bearing is pulled out housing.
One is preferably carried out mode, as it is shown on figure 3, have the first inclined-plane 5 and the second inclined-plane in described reducing groove 13
6, the angle a between described first inclined-plane 5 and horizontal plane is 30 degree, and the angle b between described second inclined-plane 6 and horizontal plane is 8
Degree.When spring catch 10 moves to 30 ° of angles with 8 ° of junction point positions, angle, for hook 14 and cup, diff. side bearing contact internal walls
Angle b between critical point the second inclined-plane 6 and horizontal plane selects 8 ° of angles to be to make the entrance differential mechanism that hook 14 can be mild
Bearing outer ring or taking-up in cup, diff. side bearing, it is to avoid damage cup, diff. side bearing, described first inclined-plane 5 and horizontal plane
Between angle a select 30 ° of angles, spring catch 10 can be made along the first inclined-plane 5 quick sliding to correct position, improve work effect
Rate.It will be appreciated by persons skilled in the art that the best angle of described first inclined-plane 5 and the second inclined-plane 6 and horizontal plane not
Being unique, its best angle needs to determine according to concrete cup, diff. side bearing size.
In order to more smoothly cup, diff. side bearing be split out from housing, above-mentioned drag hook set 2 in addition to using 2,
May be arranged as 4 or 6 or 8, it is the most that the quantity of drag hook 4 is arranged, and unloading process is the most steady, but the shortcoming brought is
Assistant tool structure is the most complicated, and manufacturing cost is the highest.
In order to ensure that in using, screw rod 7 can rotate on positioning sleeve 1 swimmingly, it is preferable that described positioning sleeve 1 includes fixed
Position portion 16 and installation portion 17, described location division 16 is integral type structure with described installation portion 17, and described location division 16 is located at described
Installation portion 17 is away from the side of described drag hook set 2, and 2 described through holes 9 are located on described installation portion 17, in described installation portion 17
Heart position is provided with stepped hole 18, is provided with thrust bearing 15 in described stepped hole 18, and one end of described screw rod 7 sequentially passes through described
Positioned by the first snap ring 19 after thrust bearing 15 and stepped hole 18.Described stepped hole 18 is arranged on the centre bit of installation portion 17
Putting, after screw rod 7 loads in stepped hole 18, the axle center that can make positioning sleeve 1 is collinear with the axle center of drag hook set 2, is so rotating
The when of screw rod 7, positioning sleeve 1 uniform stressed can be made, pull-out cup, diff. side bearing during do not result in housing and
The damage of bearing outer ring, the quality of effective parts.
Further, as depicted in figs. 1 and 2, described drag hook overlaps and has positive stop lug boss 24 on the outer wall of 2 one end, the other end
Outer wall is provided with snap ring mounting groove 20, is provided with the second snap ring 21 in described snap ring mounting groove 20, and described tapered sleeve 3 is positioned at described limit
Between position boss 24 and described second snap ring 21.By positive stop lug boss 24 and the setting of the second snap ring 21, on the one hand it is easy to cone
Set 3 carries out spacing, on the other hand makes it easy to dismounting.
The structure of the present invention, feature and action effect, above institute are described in detail above according to graphic shown embodiment
State only presently preferred embodiments of the present invention, but the present invention is not to limit practical range, every structure according to the present invention shown in drawing
Want made change, or be revised as the Equivalent embodiments of equivalent variations, still without departing from description and diagram contained spiritual time,
All should be within the scope of the present invention.
