First guide groove, one end of the pulling claw are provided with claw, and the other end is provided with screw thread, and the end of thread of the pulling claw passes through described first
Guide groove is simultaneously provided with the first wing nut on its top.
Further, the pulling claw is made up of extension pulling claw and lower pulling claw, and one end of the lower pulling claw is provided with the claw, separately
One end is provided with screw thread, and the extension pulling claw be L-shaped, its adjustment arm for including being provided with the second guide groove and with described to adjust arm vertical
Top set threaded installing arm, the end of thread of the lower pulling claw is through second guide groove and is provided with the on its top
Two wing nuts, the end of thread of the extension pulling claw are provided with through first guide groove and on its top first butterfly
Nut.Pulling claw is extended by increasing, forms extension assembling form, extends drawing diameter, it is more extensive to be allowed to the scope of application, can
For cylindrical larger bearing or other cylindrical components such as belt pulley and sprocket wheel etc..
First guide groove and the second guide groove are included by shaping-orientation groove, in adjustment, pulling claw can wherein freely
Mobile, preset clearance is small, when being fixed on bearing periphery, vertical jackscrew first is reached into suitable position, then use wing nut one by one
The pulling claw is tightened, in place just can be so that each pulling claw stress equalization, at this moment again as long as wing nut is tightened without with spanner
Rotate vertical jackscrew pulling shaft to hold, in drawing process, jackscrew is not in skewness, ensures safe and reliable, whole mistake
Journey only needs a people to complete.
Further, the top of the vertical jackscrew two adjusting nuts side by side, in use, when rotating top nut due under
The spacing of nut can move down the jackscrew, when rotating lower nut because the spacing of top nut can make the jackscrew
Move up.
Further, the top screw seat that can be slided along the vertical jackscrew is also equipped with the vertical jackscrew, the pulling claw
Screwed hole is provided with, the rotatable horizontal jackscrew equal with the pulling claw quantity is laid with the outer rim of the top screw seat,
The screwed hole of each horizontal jackscrew from the corresponding pulling claw passes through, in use, by rotating the level
Jackscrew can adjust the position of the pulling claw respectively, can be with so that the claw of the pulling claw is reliably stuck in the outer ring of bearing
Avoid deviating from from bearing.
Further, in order to preferably position and power transmission, the lower end of the vertical jackscrew is taper.
Compared with prior art, the technical solution of the utility model has advantages below：
Bearing drawing device provided by the utility model, globality is preferable, simple to operation, in the absence of security risk, leads
Stress point position is accurate when presence to groove to carry, and is not in skewness in whole loading process, existing with producing
The versatility of field maintenance is preferable, and constructor closes mechanical property requirements, overcomes the irrational aspect of original structure, and increase is horizontal in addition
Jackscrew can prevent that pulling claw slips from bearing during drawing.
