Groove；Lifting screw, is installed on described framework；Oil cylinder, is connected by slide plate is fixing with the bottom of described lifting screw, described cunning
Plate is slidably connected to described chute；Hydraulic pump, is used for driving described cylinder action；Claw pedestal, before being set in described oil cylinder
End；Master jaw, described master jaw is three, and three master jaws are distributed in described pedestal outer surface, in being provided with in described master jaw
Dead slot body；Claw, described claw is three, and three claws are slidably connected to the hollow cell body of described three master jaws respectively；Hang
Hook, described hook is three, and three hooks are respectively arranged in the front end of described three claws.
Further, a height of 35 mm*20 mm*10mm of the wide * of long * of described hook.
Further, the material of described hook is 45# Fine Steel Casting iron.
Further, when dismounting, described claw is fixed at described rotor bearing inner ring, and described hook hangs over described turning
At sub-bearing inner race flange.
Beneficial effect:
1. the present invention can improve bearing removal efficiency when internal rubber mixer rotor bearing is changed and assembles, and solves to tear open at present
Unload difficult problem；
2. its height of the present invention and diameter can be adjusted, it is possible to the internal rubber mixer adapting to different type of machines uses, the most also
Can use as the dismounting of other equipment large size bearings；
3. the present invention uses oil pressure to be controlled, its stable action, and pressure is big, it is possible to drawing required for meeting big bearing removal
Power；
4. apparatus of the present invention are three-pawl type structure, be evenly distributed on bearing circumferencial direction and be during dismounting, and uniform force will not be countershaft
Manufacture into damage；
5. the present invention is by three-dimensional force analysis, contrasts the data such as axially loaded of bearing simultaneously, and when determining dismounting, claw is fixed
At bearing inner race, inner ring can carry out activity vertically, it is to avoid it causes bearing damage because of jam, is rubbing surface because of outer ring simultaneously,
The main source of dismounting pulling force, hangs over inner ring by hook, and moment is big, it is simple to dismounting.

Detailed description of the invention
Fig. 1 is the structural representation of internal rubber mixer rotor bearing provision for disengagement of the present invention.As it is shown in figure 1, this
Bright internal rubber mixer rotor bearing provision for disengagement, including lifting screw 1, framework 2, hydraulic pump 3, oil cylinder 4, master jaw 5,
Claw 6 and hook 7.
Specifically including: framework 2, described framework 2 is provided with chute 9；Lifting screw 1, is installed on described framework 2；Oil cylinder
4, it is connected by slide plate 10 is fixing with the bottom of described lifting screw 1, described slide plate 10 is slidably connected to described chute 9；Hydraulic pressure
Pump 3, is used for driving the action of described oil cylinder 4；Claw pedestal 11, is set in the front end of described oil cylinder 4；Master jaw 5, described master jaw
Being three, three master jaws are distributed in described pedestal outer surface, are provided with hollow cell body 12 in described master jaw；Claw 6, described card
Pawl is three, and three claws are slidably connected to the hollow cell body of described three master jaws respectively；Hook 7, described hook is three,
Three hooks are respectively arranged in the front end of described three claws.Provision for disengagement of the present invention is three-pawl type structure, uniformly divides during dismounting
Cloth when bearing circumferencial direction, uniform force, rotor bearing will not be caused damage.The present invention is by lifting screw regulation height
Degree, adjusts the distance of three claws by master jaw, can dismantle the internal rubber mixer rotor bearing type of different type of machines.
It addition, in the present embodiment, calculation bearing of the present invention dismounting pulling force, according to the required pulling force of its dismounting and bearing roller
Gap, designs hook dimensions.Such as, the bearing removal pulling force of the rotor bearing 8 dismantled is 100KN, required according to its dismounting
Pulling force and bearing roller gap, by a height of for the wide * of long * of hook dimensions 35 mm*20 mm*10mm, employing hook material is simultaneously
45# Fine Steel Casting iron carries out modifier treatment, it is ensured that link up with when dismounting indeformable.
And, the present invention by three-dimensional force analysis, contrasts the data such as axially loaded of bearing, card when determining dismounting simultaneously
Pawl is fixed on rotor bearing inner ring, so that hanging at rotor bearing inner ring flanging, inner ring can carry out activity vertically, keeps away
Exempting from it and cause rotor bearing to damage because of jam, be rubbing surface because of outer ring simultaneously, the main source of dismounting pulling force, in hanging over hook
Circle, moment is big, it is simple to dismounting.
Below, it is further detailed having provision for disengagement as constituted above.Internal rubber mixer of the present invention turns
In use, first according to rotor bearing centre-height, regulation lifting screw drives oil cylinder lifting, makes oil in sub-bearing provision for disengagement
Cylinder center is highly consistent with bearing centre；Adjusting jaw position further according to bearing inner race, claw can hollow groove along master jaw
Body radially moves so that it is size is consistent with bearing inner race, is hung over by hook at rotor bearing inner ring flanging；Start hydraulic pump,
The piston rod of oil cylinder withstands on the axle of rotor bearing, is disassembled by rotor bearing by oil pressure from the support of limit.
The present invention can summarize with other the concrete form without prejudice to the spirit or essential characteristics of the present invention.Therefore, nothing
Opinion is from the point of view of which point, and the embodiment above of the present invention all can only be considered the description of the invention and can not limit this
Bright, claims indicate the scope of the present invention, and the scope of the present invention is not pointed out in above-mentioned explanation, therefore, with this
Any change in the suitable implication of claims of invention and scope, is all considered as being included in the claim of the present invention
In the range of book.
