Brake arm is locked so as to which braked wheel be fixed to braked wheel direction, only need to be by outside traction sheave and braked wheel after outer end cap is removed
The clamping screw that edge is connected removes the dismounting that traction sheave can be achieved, and new traction sheave is replaced with, then outer end cap is pacified
Install, traction sheave can be completed more by unclamping regulating bolt 22 and both sides brake arm is returned into former scale being loaded on steel wire rope
Change；
Stator：By the way that the horizontal clamping screw 18 in cylindrical shell week portion is removed, you can by the cylindrical shell equipped with stator
And side cover unloads, then replace with equipped with new stator；
Rotor：Traction sheave and braked wheel are fixed by Special fixing machine structure, after the cylindrical shell equipped with stator is removed,
Rotor cover locking nut is removed, you can rotor set is unloaded from rotating shaft together with rotor, then by new rotor and rotor set
Load onto, locking nut is locked, so as to realize the replacing of rotor；
Another removable bearing：It is by Special fixing machine structure that traction sheave and braked wheel is radially fixed, crossed with preventing from tearing open shape
Rotating shaft shifts rotation in journey, can be safeguarded without fixed lift car so as to realize；Cylindrical shell and side cover are unloaded
After lower, then locking nut unloaded so that rim body and rotor to be unloaded from roller end, by by specific purpose tool by bearing block and
Bearing is removed from the bearing seat of supporting seat frame, and then another removable bearing being arranged in bearing block is pulled down and replaced with
Installed after new bearing in bearing block, the bearing sleeve for replacing with new bearing is connected in rotating shaft and with bearing seat fixation
Connect, so as to realize that the scene dismounting of another removable bearing is safeguarded, the rotor of dismounting and side cover are reinstalled into back support base afterwards
On frame.
