Referring to Fig. 1, Fig. 1 shows a kind of pulley extractor of embodiment of the present utility model, wherein, the pulley extractor includes pulling out
Ring 1, support ring 2 and multiple lifting bodies 3 are taken, ring 1 of choosing is coaxially disposed with support ring 2, ring 1 of choosing includes the He of sleeve 10 of choosing
Retention mechanism 11, sleeve 10 of choosing, through the centre bore of ring 1 of choosing, is formed with sleeve 10 of choosing and axially pulls out towards support ring 2
Chamber 103 is taken, sleeve 10 of choosing includes the first half sleeves 101 of subdivision vertically and the second half sleeves 102, the first half sleeves 101
It is hinged with two distal ends relative to support ring 2 of the second half sleeves 102, and is formed between two near-ends and axially pulls out
The axially open 104 of the connection of chamber 103 is taken, two near-ends can be pivoted around the pin joint of distal end and opened, and by retention mechanism
11 secure closures；Multiple lifting bodies 3 are arranged along the circumferential direction of ring 1 of choosing and the direction for being directed away from support ring 2 is pushed up
Rise ring 1 of choosing.
This utility model is innovatively arranged in the centre bore of ring 1 of choosing and chosen sleeve 10, and by the sleeve 10 of choosing
It is arranged to one end and is hinged the other end to pivot two and half sleeves that open, i.e. the first half sleeves 101 and the second half sleeves 102 pass through
Two and half sleeves 101 and 102 surround gear to be removed for 360 ° so that gear to be removed is contained in axially chooses in chamber 103, and
Clamped by retention mechanism 11, recycle lifting body 3 by the related gear to be removed clamped by sleeve 10 of choosing of ring 1 of choosing
The direction jacking of support ring 2 is directed away from together, to realize dismantling the purpose of gear.So as to ensure that gear to be removed is uniformly received
Power, and lifting surface area is big, significantly reduces the damaged condition of gear to be removed, while also causing pulley extractor pair of the present utility model
Whether there is the gear in hole to be capable of achieving not damaged dismounting in center, improve the versatility of pulley extractor；Simultaneously because support ring 2 is made
For supporting surface of the lifting body 3 in jacking so that increased the Area of bearing of gear to be removed of choosing, also protect to be removed
The end cap of the installation axle of gear is without damage.Especially, pulley extractor of the present utility model is particularly suited for the gear of central imperforate
Dismounting.
Referring specifically to Fig. 1, in infinite mode, the cross section of sleeve 10 of choosing is annular, then the first half sleeves 101
