2, the elastic cone covers 1 one end and is provided with annular claw 3, and inner face and the end face of needle bearing 4 of the claw 3 match, institute
It is the small taper hole 5 of outer imperial palace to state elastic cone to cover 1 endoporus correspondence claw 3 end, on the face of taper hole 5 of the elastic cone set 1 axially
Provided with least one opening 6, the taper bar 2 that rises includes outer cone section 21 and cylindrical section 22, the outer cone section 21 and elastic cone
The taper hole 5 of set 1 coordinates, and the cylindrical section 22 is set through elastic cone set 1 and its end is extended to outside elastic cone set 1.
The present invention, through needle bearing endoporus, makes elastic cone cover claw inner face and the rolling of end using elastic cone set
The end face of needle bearing is fitted close, and elastic cone is covered into tensioner in needle bearing using the taper bar that rises, then to elastic cone
Set, which applies pulling force, to disassemble needle bearing.Moving back for hole dress needle bearing can be greatly improved and unload efficiency, reduction work
Intensity, while also ensuring that bearing mounting hole inner surface and accessory are injury-free.
Embodiment 1：As shown in figure 1, the bottom of taper hole 5 of elastic cone set 1 is provided with internal thread 7, the taper is risen bar 2
Also include bolt section 23, the bolt section 23 is arranged on the one end of cylindrical section 22, and the bolt section 23 can cover 1 bottom with elastic cone
Portion's internal thread 7 coordinates, the taper rise bar 2 outer cone section 21 end faces be provided with spanner coordinate interior hexagonal hole 8.Taper is risen
Bar is in elastic cone set, and through needle bearing endoporus, using the cooperation of spanner and interior hexagonal hole, taper is risen the spiral shell of bar
Bolt section covers bottom screw-internal thread fit with elastic cone, and as taper is risen, elastic cone is covered tensioner in needle bearing to bar by precession forward
Endoporus, makes elastic cone cover the end face tight fit of the claw inner face and needle bearing of end, rise bar or elastic cone to taper
Shape set, which applies pulling force, to disassemble needle bearing out of mounting hole.
Referring to Fig. 1,3,4, the taper rise bar 2 the diameter of cylindrical section 22 be more than bolt section 23 Major Diam, the bullet
Property taper sheath 1 the bottom of taper hole 5 be straight hole 9, the diameter of straight hole 9 be more than internal thread 7 big footpath and bolt section 23 screw thread it is big
Footpath, the length of straight hole 9 is more than the length of cylindrical section 22.It can be risen using the structure ensureing taper in the presence of bar intensity, energy
Enough ensure taper rise bar cylindrical section elastic cone set in mobile space, make taper rise bar outer cone section have enough displacements
The taper hole spreading that elastic cone can be covered, and then elastic cone is covered tensioner in needle bearing endoporus.
Embodiment 2：As shown in Fig. 2 the taper is risen, the bolt section 23 of bar 2 is extended to outside elastic cone set 1 and with rising
Tight nut 10 coordinates, and the tensioner nut 10 is arranged on elastic cone and covered outside 1 endoporus.Risen bar by tensioner nut and taper
Bolt section coordinates, and as taper is risen the taper hole spreading that the reach of bar covers elastic cone, and then elastic cone is covered tensioner in rolling
Needle bearing endoporus.
Wherein, four openings 6 are laid with the face of taper hole 5 of the elastic cone set 1,6 length of the opening are more than cone
The length of hole 5, it is ensured that elastic cone set has enough elasticity and intensity.
Disassembling operations for convenience, the taper rise bar 2 bolt 23 ends of section provided with extension section 24, the extension section 24
End is provided with the attaching nut 12 coordinated with pin removal 11, and the pin removal 11 is sleeved in extension section 24.Utilize pin removal energy
Enough bars that more easily rises to taper apply pulling force, easily move back needle bearing and unload down.
Wherein, the cross section of the extension section 24 is polygon.Using the foreign side of extension section to pin removal in circumferencial direction
Carry out spacing, it is to avoid pin removal rotates with respect to the taper bar that rises.
Wherein, elastic cone set 1 it is cylindrical by claw root taper transitions to the face of cylinder, the claw 3 and needle roller
The external diameter of bearing 4 is 30-50mm.For the needle bearing between external diameter 30-50mm because of its compact structure, equipment essence is often arranged on
Compact part position the characteristics of, the class bearing need change or overhaul of the equipments dismounting when use special tooling, make bearing outer ring end face with
The outer claw inner face of elastic cone set is contacted in circumferential maximum area, the circumferential uniform force of end face of bearing, can be quickly by axle
Hold and disassemble, while bearing and installation internal surface of hole can be protected injury-free.
The operation principle of the present invention is as follows：Unclamping the taper bar that rises makes elastic cone set resile, and will rise with taper
The elastic cone set of bar makes taper rise through needle bearing endoporus, the interior hexagonal hole for the rod end head that then rises using the stubborn taper of spanner
Bar advances, and at the same time elastic cone set is softened expansion, the claw inner face and needle bearing end contact of elastic cone set
And clamping, now pin removal and the taper bar that rises are connected using M8 attaching nut, smoothly pulled out needle bearing using pin removal
Go out.The invention is applicable to through hole or moving back for the needle bearing of blind hole is unloaded.
The present invention is more suitable for applying in the maintenance of ZZB series of combination electric intelligent triggers, due to the Series Intelligent trigger
Rotary part all installs needle bearing using in through hole or blind hole, and fault rate is high, maintenance is frequent, uses bearing after the present invention
Move back and unload and can be rapidly completed in production scene, it is possible to increase the overhaul efficiency of ZZB series of combination electric intelligent triggers, reduction work is strong
Spend and protect installation position and accessory not to receive damage.
Specific case used herein is set forth to the principle and embodiment of the present invention, and above example is said
The bright method and its core concept for being only intended to help to understand the present invention.It should be pointed out that for the ordinary skill of the art
