Summary of the invention
The technical problem to be solved is to overcome above-mentioned the deficiencies in the prior art, it is provided that a kind of rational in infrastructure, easy to assembly, is simple to manufacture, and operation saves time, and dismounting is reliable, it is adaptable to the bearing extractor of dismounting part bearing inside blind hole.
The present invention solves above-mentioned technical problem and the technical scheme is that a kind of bearing extractor, it includes pull bar, expansion sleeve, nut, bracing ring, helps pull a cart, it is characterized in that: described pull bar front end is provided with contraction conehead, rear portion is provided with and nut and the screw rod being connected of helping pull a cart；Described expansion sleeve front end is provided with expanding cone mouth, described pull bar front portion is contained in expansion sleeve, and contraction conehead and expanding cone mouth on pull bar are coincide, and pull bar inserts in workpiece blind hole middle (center) bearing endoporus together with expansion sleeve, rotating fastening nut, pull bar, expansion sleeve, bearing, nut are tightly fixed；Described bracing ring is arranged on outside expansion sleeve, and coordinates restriction expansion sleeve to circumferentially rotate by screw and keyway；The described screw rod helped pull a cart with pull bar is connected, and helps pull a cart and abuts against bracing ring rear end face；Described bracing ring and be respectively equipped with handle on helping pull a cart, relatively rotate bracing ring and help pull a cart on handle, torsion is helped pull a cart, it is achieved extracting of bearing.
Described expansion sleeve cylindrical is provided with step, and front end cone mouth is axially arranged with opening elongate slots, and rear portion outer round surface is axially arranged with keyway.
Being provided with the bulge loop coordinated with expansion sleeve cylindrical step in the middle of described bracing ring endoporus, bulge loop front portion is provided with the space extracting bearing.
Being radially provided with screw on the cylindrical of described bracing ring rear portion, described screw is screwed into this screw in expansion sleeve keyway, limits circumferentially rotating of expansion sleeve.
When the present invention uses, pull bar loads in expansion sleeve so that it is on contraction conehead and expanding cone mouth coincide, bracing ring is arranged on outside expansion sleeve.And back stay inserts in workpiece blind hole middle (center) bearing endoporus together with expansion sleeve, rotate fastening nut, it is achieved pull bar, expansion sleeve, bearing, nut are tightly fixed.Gripping the handle on bracing ring, rotate the handle on helping pull a cart, torsion is helped pull a cart, and can be extracted by bearing.Against existing technologies, present configuration is reasonable, easy to assembly, is simple to manufacture, and operation saves time, and dismounting is reliable, it is adaptable to that dismantles part bearing inside blind hole extracts use.
Accompanying drawing explanation
The invention will be further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of confined state of the present invention.
Fig. 2 is that the A-A of Fig. 1 is to structural representation.
1. workpiece in figure, 2. pull bar, 3. bearing, 4. expansion sleeve, 5. bracing ring, 6. screw, 7. handle, 8. nut, 9. help pull a cart, 10. handle.
Detailed description of the invention
It can be seen that a kind of bearing extractor from Fig. 1, Fig. 2, it includes pull bar 2, expansion sleeve 4, nut 8, bracing ring 5, helps pull a cart 9 etc..Described pull bar 2 front end is provided with contraction conehead, and rear portion is provided with and nut 8 and 9 screw rods being connected of helping pull a cart；Described expansion sleeve 4 front end is provided with expanding cone mouth, and described pull bar 2 front portion is contained in expansion sleeve 4, makes the contraction conehead on pull bar 2 and expanding cone mouth coincide, and the diameter of expansion sleeve 4 is less than bearing 3 internal diameter.Then by anterior for expansion sleeve 4 cylindrical through bracing ring 5 endoporus, and then pull bar 2 is inserted in workpiece 1 blind hole middle (center) bearing 3 endoporus together with expansion sleeve 4.Rotating fastening nut 8, pull bar 2 moves to expansion sleeve 4 point diameter more than bearing 3 internal diameter, and pull bar 2, expansion sleeve 4, bearing 3, nut 8 are tightly fixed.
Described bracing ring 5 is arranged on outside expansion sleeve 4, and coordinates restriction expansion sleeve 4 to circumferentially rotate by screw 6 and keyway；Described helping pull a cart 9 is connected with the screw rod of pull bar 2, and helping pull a cart 9 abuts against bracing ring 5 rear end face；Described bracing ring 5 and help pull a cart and be respectively equipped with handle 10 and handle 7 on 9.Handle 10 is welded on bracing ring 5 cylindrical, and handle 7 is welded on helps pull a cart on 9 cylindricals.Handle on relatively rotating bracing ring and helping pull a cart, torsion is helped pull a cart, it is achieved extracting of bearing.
Further, described expansion sleeve 4 is multidiameter, and cylindrical is provided with step, and front end cone mouth is axially arranged with opening elongate slots, and rear portion outer round surface is axially arranged with keyway.Under pull bar 2 shrinks conehead effect, opening elongate slots is easy to tapering spreading, produces the amount of rising enough extracting bearing, tensioner bearing 3, it is achieved pull bar, expansion sleeve, bearing, being tightly fixed of four parts of nut.
Further, being provided with, in the middle of described bracing ring 5 endoporus, the bulge loop coordinated with expansion sleeve 4 cylindrical step, bulge loop front portion is provided with the space extracting bearing.
Further, described bracing ring 5 rear portion cylindrical being radially provided with a screw, described screw 6 is screwed into this screw in expansion sleeve 4 keyway, limits circumferentially rotating of expansion sleeve 4.
When the present invention uses, pull bar loads in expansion sleeve so that it is on contraction conehead and expanding cone mouth coincide, bracing ring is arranged on outside expansion sleeve.And back stay inserts in workpiece blind hole middle (center) bearing endoporus together with expansion sleeve, rotate fastening nut, it is achieved pull bar, expansion sleeve, bearing, nut are tightly fixed.Gripping the handle on bracing ring, rotate the handle on helping pull a cart, torsion is helped pull a cart, and can be extracted by bearing.
Present configuration is reasonable, easy to assembly, is simple to manufacture, and operation saves time, and dismounting is reliable, it is adaptable to that dismantles part bearing inside blind hole extracts use.
