In a kind of specific embodiment scheme, the utility model provides a kind of axle sleeve disassembling fixture, for removing and installing
Axle sleeve in the mounting hole of equipment 9, including dismantle nut 1, dismantle tapered sleeve 2, removal rod 3 and relative to the fixation of equipment 9
Positive stop, removal rod 3 are provided with the spacing ring 7 for being used for abutting with end face of shaft bush, and the periphery of removal rod 3 is provided with same with removal rod 3
The conical surface shaft part 6 of axle arrangement, cone bottom one end of conical surface shaft part 6 is arranged towards spacing ring 7 and vertex of a cone one end is towards the end of removal rod 3
Arrangement, dismounting tapered sleeve 2 and conical surface shaft part 6 coordinate and can radially elastic deformation, the side wall of dismounting tapered sleeve 2, which is provided with, cracks 5, tears open
The periphery and dismounting nut 1 screw thread for unloading tapered sleeve 2 coordinate, and vertex of a cone one end of dismounting tapered sleeve 2 is connected to positive stop.
Wherein, the fixed and arranged of positive stop (not shown) relative device 9, it is to provide limit for dismounting tapered sleeve 2 that it, which is acted on,
Position support, avoid dismounting tapered sleeve 2 from being moved to vertex of a cone direction, that is, avoid dismounting tapered sleeve 2 from being slipped from the conical surface shaft part 6 of removal rod 3
Out, this way it is secured that dismounting tapered sleeve 2 is fixed in the position for the axis direction for being disassembled axle sleeve, so as to so that dismounting
Bar 3, which is forced to push vertically, is disassembled axle sleeve.Specifically, the positive stop can be designed as being fixed on the bearing on ground, also may be used
To be designed as being fixedly connected on the fixed block in the outside of equipment 9 etc..It is reserved between positive stop and equipment 9 for placing removal rod
3 operating space, user dismantles nut 1 in the operating space internal rotation, so as to ensure being smoothed out for unloading process.
For the ease of arranging whole axle sleeve disassembling fixture, it is preferable that this programme is additionally provided with positive stop for branch
The brace groove of removal rod 3 is supportted, when arranging frock, it is possible to removal rod 3 is ridden in brace groove, so just avoided artificial
Fixed removal rod 3 is helped, it is easy to operate, reduce labor intensity.
Dismounting tapered sleeve 2 is the screwed taper sheath structure in a periphery, and its side wall cracks 5 so that its own can be along footpath
To elastic shrinkage or expansion, cracking 5 can be designed as axially disposed vertical masonry joint, may be designed in shaped form seam.Dismounting cone
Set 2 is set in the periphery of conical surface shaft part 6 of removal rod 3 and can sliding axially along conical surface shaft part 6.The inner ring of dismounting nut 1 is set
There is internal thread, the internal diameter of dismounting nut 1 is certain, therefore, during dismounting nut 1 rotates against with dismounting tapered sleeve 2, is torn open
Unloading while the axially opposed dismounting nut 1 of tapered sleeve 2 moves can gradual radially elastic deformation.
Preferably, the spacing ring 7 in this programme is the shaft shoulder for being arranged at the periphery of removal rod 3, as shown in fig. 6, utilizing the shaft shoulder
Side abutted against with being disassembled the end face of axle sleeve, so as to during the thrust motion of removal rod 3, axle sleeve release will be disassembled
The mounting hole of equipment 9.Certainly, the end face of removal rod 3 can also be designed as spacing ring 7 by this programme, that is, utilize the one of removal rod 3
Individual end face abuts against with being disassembled the end face of axle sleeve, equally being capable of push collar.
Preferably, the removal rod 3 in this programme is additionally provided with the importing shaft part 8 for inserting axle sleeve inner ring, as shown in fig. 6,
Above-mentioned spacing ring 7 is arranged such, when arranging the axle sleeve disassembling fixture positioned at importing between shaft part 8 and conical surface shaft part 6, so that it may
So that importing shaft part 8 to be initially inserted into the inner ring for being disassembled axle sleeve, can be so disassembled with being more easily connected to spacing ring 7
The end face of axle sleeve, in unloading process, removal rod 3 also will not be moved at will, ensure being smoothed out for unloading process.
Nut 1 is dismantled for the ease of rotation, the periphery for dismantling nut 1 can be designed as hexagonal configuration, four sides by this programme
The polygon such as shape or octagon, it is easy to user to rotate dismounting nut 1 using spanner.Certainly, in another preferred scheme, tear open
The periphery of removing nut 1 is provided with least one handle 4, as shown in figure 1, user directly can rotate dismounting spiral shell by handle 4
Mother 1, the sleeve pipe of lengthening can also be arranged outside handle 4 certainly, so as to which further the torque of nut 1 is dismantled in increase rotation, and then
Bigger thrust is produced to removal rod 3, makes unloading process lighter.
The course of work of the present utility model is as follows：
End face of shaft bush is disassembled in use, the spacing ring 7 of removal rod 3 is connected to, dismounting tapered sleeve 2 is set in conical surface axle
Section 6 peripheries simultaneously be arranged between positive stop and equipment 9, then, will dismantle nut 1 from dismounting tapered sleeve 2 the vertex of a cone to cone bottom side
Rotated to promoting.Because the internal diameter for dismantling nut 1 is certain, and dismantle tapered sleeve 2 by the barrier effect of positive stop and
It can not be moved to vertex of a cone direction, therefore, during dismounting nut 1 screws, elastic deformation and radially occurs for dismounting tapered sleeve 2
Shrink, dismounting tapered sleeve 2 will push conical surface shaft part 6 to axle sleeve direction is disassembled, so that removal rod 3 is overall with dismounting nut
1 precession and pushed to axle sleeve direction is disassembled, and then will be disassembled in the mounting hole of axle sleeve slave unit 9 and pushed away using spacing ring 7
Go out.
This programme is using the cone match relation and dismounting tapered sleeve 2 for dismantling tapered sleeve 2 and removal rod 3 with dismantling nut 1
Screw thread matching relationship, the rotary motion of dismounting nut 1 is set to be converted into the linear motion of removal rod 3, so as to fast quick-detach axle
Set, axle sleeve is avoided to produce infringement to the mounting hole of equipment.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or new using this practicality
Type.A variety of modifications to these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice can be realized in other embodiments in the case where not departing from spirit or scope of the present utility model.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
