In order to achieve the aim, the utility model provides the technical scheme that the mechanism for detaching the bearing at the extremely small space comprises a rotor and a bearing, wherein the bearing is sleeved outside the rotor;
Further comprises:
The first support, its movable sleeve establishes in the outside one side of rotor, the outside opposite side of rotor is provided with the second support, the upper end of first support is provided with first backing plate, the upper end of second support is provided with the second backing plate, the bottom of first support is provided with first base pad, the bottom of second support is provided with the second base pad, the inboard of first backing plate and second backing plate all is provided with the bayonet lock.
Preferably, the surfaces of the first backing plate and the second backing plate are respectively provided with a first through hole, the upper ends of the first support and the second support are respectively provided with a fifth threaded hole, and the first through holes and the fifth threaded holes are aligned.
Preferably, the surfaces of the first base pad and the second base pad are respectively provided with a second through hole, the bottom surfaces of the first support and the second support are respectively provided with a sixth threaded hole, and the second through holes are aligned with the sixth threaded holes.
Preferably, the first connecting holes are symmetrically formed in two sides of the outer portion of the second support, and the second connecting holes are formed in the outer portions of the first support and the second support.
Compared with the prior art, the utility model has the beneficial effects that:
According to the tooling fitting that the motor model was selected to correspond, install the top at first support and second support respectively with first backing plate and second backing plate through the bolt, with the inboard bayonet lock of first backing plate and second backing plate along the clearance lock between rotor and the bearing, splice two sets of supports that have the rotor after will buckling through the bolt, rethread bolt installs first base pad and second base pad in the bottom of first support and second support respectively, put into under manual press with support and the motor rotor after the equipment, use the press to extrude the bearing, it is little to have solved the bearing space, the unable dismantlement problem of bearing. The bearing is nondestructively detached from the rotor, unnecessary occupation of the rotor and the bearing is reduced, a flange plate is not needed, other special tools are not needed, waste is avoided, and cost is reduced.
