Embodiment
The utility model is further described presently in connection with attached drawing.These attached drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the utility model, therefore it only shows the composition related with the utility model.
A kind of taper roll bearing outer ring extracting tool as shown in Figure 1, 2, including：
Rise ring 6, and 6 endoporus of ring that rises is up big and down small taper hole, and the coning angle of taper hole is 6.5 °, and 6 periphery of ring that rises is and circle
Taper that 2 internal taper hole of taper roller bearing outer ring matches, up big and down small, 6 lower end of ring of rising are equipped with annular male half coupling 6-1, and rise ring 6
Upper end is arranged with connecting screw hole 6-2, and the ring 6 that rises forms a pair of symmetrical Hough body, two Hough body pairings along axis after subdivision
After be inserted in 2 internal taper hole of taper roll bearing outer ring；
Round estrade 7, the coning angle of its taper surface is 6.5 °, and after 7 small end of round estrade is inserted in 6 taper hole of ring that rises, two breathe out
Husband's body radially expansion, so as to force the annular male half coupling 6- of the ring 6 that rises for stretching out 2 internal taper hole small end of taper roll bearing outer ring
1 engages with 2 internal taper hole small end of taper roll bearing outer ring；
Pulling plate 3, it is equipped with installation screw positioned at the top of ring 6 of rising, the middle part of pulling plate 3, and installation screw both sides are arranged with installation
Hole；
Supporting sleeve 4, positioned at rising between ring 6 and pulling plate 3,4 lower end of supporting sleeve needs to be torn open outside taper roll bearing by installing for it
The part support of circle 2,4 upper end of supporting sleeve is welded with level board；
A pair of of studs 5, the ring 6 that rises are connected by two studs 5 with pulling plate 3, and 5 lower end of studs screws in the ring that rises
In connecting screw hole 6-2 on 6,5 upper end of studs is movable through after being arranged on the perforation on 4 level board of supporting sleeve upwards, then
It is fixedly connected by 3 mounting hole of pulling plate and a pair of of nut with pulling plate 3；
