In the prior art, generally, dismantle self-aligning bearing 2 through the tool of lama, during the dismantlement, the bearing is very easily harmed to the outer lane atress of self-aligning bearing 2, does not have unusually in order to ensure the installation, all needs to be changed new bearing at every turn, and cost of maintenance is high.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a pull roller bearing's extracting tool has the effect that reduces cost of maintenance.

In order to achieve the technical purpose, the utility model provides a following technical scheme: the utility model provides a extracting tool of carry over pinch rolls bearing, includes the bracing piece of two butt between carry over pinch rolls and self-aligning bearing, the bracing piece is located the outside of adapter sleeve, the axle head cover of carry over pinch rolls is equipped with the sleeve of cylinder, telescopic internal diameter is the same with the external diameter of carry over pinch rolls axle head, the one end that the carry over pinch rolls was kept away from to the sleeve is provided with the end plate, the sleeve is provided with the hammer that is used for knocking the end plate outward.

By adopting the technical scheme, when the accessory of the traction roller needs to be disassembled, the fastening nut and the gasket are disassembled firstly, then one worker firstly horizontally places two support rods between the traction roller and the self-aligning bearing respectively, and makes the support rods abut against the inner ring part of the self-aligning bearing, the second worker sleeves the sleeve at the shaft end of the traction roller, the end surface of the sleeve abuts against the fastening sleeve, the second worker holds the sleeve, the third worker uses an iron hammer to knock the end plate of the sleeve, the fastening sleeve and the self-aligning nut slide along the shaft of the traction roller under the pushing of the sleeve, when the other end of the support rod abuts against the end surface of the traction roller, the self-aligning bearing cannot move along with the fastening sleeve along with the continuous pushing of the sleeve, a gap is generated between the self-aligning bearing and the fastening sleeve, at the moment, the worker can take down the self-aligning bearing firstly, then pulls down the fastening sleeve, and when disassembling, force can not be applied to the outer ring of the aligning bearing, the bearing is prevented from being damaged, the aligning bearing does not need to be replaced, and the maintenance cost is reduced.

Preferably, a plurality of handles for holding are arranged on the outer side wall of the sleeve.

Through adopting above-mentioned technical scheme, the staff can fix the sleeve through holding the handle, has made things convenient for staff's operation.

Preferably, the adapter sleeve is provided with a deformation opening along the length direction thereof.

Through adopting above-mentioned technical scheme, take off the back with self-aligning bearing, lose self-aligning bearing's injecing back, owing to warp open-ended existence, the adapter sleeve just can not closely laminate on the axle of carry over pinch rolls, has made things convenient for the dismantlement of adapter sleeve, has improved the simple operation nature.

Preferably, the diameter of the support rod is smaller than the gap between the inner ring and the outer ring of the self-aligning bearing, one support rod is located at the upper half part of the self-aligning bearing, and the other support rod is located at the lower half part of the self-aligning bearing.

Through adopting above-mentioned technical scheme, two spinal branch vaulting poles support self-aligning bearing's upper and lower portion respectively, when having guaranteed that self-aligning bearing receives the promotion, self-aligning bearing atress is even, avoids self-aligning bearing's inner circle collision adapter sleeve, leads to self-aligning bearing's inner circle to be gouged, has improved structural rationality.

To sum up, the utility model discloses following effect has been gained:

1. with the help of the cooperation of sleeve and bracing piece, realized the reasonable dismantlement of self-aligning bearing.
