Can firmly and live generator magnetic pole Damper Winding and be flexible coupling the nut at the back side.
In order to solve above-mentioned technical problem, the technical solution of the utility model is：A kind of generator magnetic pole Damper Winding is torn open
Holding tool, including the fix bar of a U-shaped, described fix bar has a longer leading portion and a shorter back segment, in the end of back segment
It is provided with one for installing the square toes of sleeve, be connected with torsion limiting unit in leading portion end.
Described torsion limiting unit includes the sleeve pipe being fixedly connected on leading portion end, has been inserted into a slide bar in sleeve pipe,
It is fixedly connected the termination greater diameter than casing tube internal hole diameter in slide bar end.
Described torsion limiting unit includes gripper shoe, offers mounting hole in the middle part of gripper shoe, fixed on gripper shoe end face
There is a plurality of rubber card strip, each card article is arranged in parallel successively from top to bottom, is provided with outer spiral shell in fix bar leading portion away from back segment one end
Line, leading portion has externally threaded one end and is located at gripper shoe kidney-shaped in the hole, and is being provided with nut on the external screw thread of leading portion.
Also include rubber washer and counterbore magnet, when sleeve is installed on square toes, rubber gasket and counterbore magnet are inserted in
In sleeve, and rubber washer and counterbore magnet are threadeded with square toes by countersunk head screw.
The beneficial effects of the utility model are：Sleeve can be extend into the back side that is flexible coupling by the fix bar of U-shaped, and by sleeve
Be enclosed within completely and be flexible coupling on the nut at the back side, by reverse limiting unit fix bar is fixed, limit nut reverse make its
And live non-slip during screw, magnetic pole or iron core will not be collided, improve bolt disassembly efficiency.
