Fig. 2 is the exploded perspective view of this utility model bearing extractor；
Fig. 3 is the cut-away diagram of this utility model bearing extractor.
Detailed description of the invention
The embodiment of this utility model bearing extractor: as Figure 1-3, bearing extractor, including tubular
Device body 3, device body 3 is provided with for holding holding assembly tightly, holding group tightly of bearing tightly along the radial direction of bearing to be removed
Bearing place is installed axle after holding bearing tightly and is applied the push rod 5 of axial thrust by part.Device body 3 is provided with to be embraced for installation
The installation cavity of tight assembly, the right side of device body 3 is provided with the screwed hole for push rod 5 Screw assembly.The periphery wall of device body 3
Being provided with the spline structure for coordinating with spanner spline, spline structure is formed by four standstill faces 4, two relative standstill faces
4 be arranged in parallel.
Holding assembly tightly and include two clamping elements 1, clamping element 1 is in circular arc tabular, for semi-ring, two clamping elements 1 surround for
That holds bearing tightly holds space tightly.The inwall of clamping element 1 is provided with for increasing the frictional force between clamping element and bearing outer peripheral face
Anti-slip tank 12, clamping element 1 inwall is provided with multiple circumferentially spaced setting and the projection of axially spaced setting, each projection it
Between groove formed anti-slip tank.By arranging anti-slip tank, prevent, when drawing bearing, skidding occurring.On two clamping elements 1
The end face of each projection be collectively forming when holding bearing tightly the clamping face being close on bearing outer peripheral face.Clamping element 1 is provided with use
