For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of semiaxis and bearing disassembling device, comprise sleeve, described sleeve one end is sealed end, described sealed end is provided with through hole, described sleeve inner is provided with connecting bolt and inwall is established threaded cylinder, the rear end of described cylinder is expand tube shape, cylinder middle part is stretched into by cylinder rear end in described connecting bolt one end, and be spirally connected with cylinder, the other end stretches out sleeve by through hole, and is spirally connected with nut, described nut press seal end.
Described cylinder one end is provided with peep hole.
Described connecting bolt end is provided with gripping section, and described gripping section outer surface is flat.
The invention also discloses the provision for disengagement of bearing outer ring, comprise sleeve, described sleeve one end is sealed end, described sealed end is provided with through hole, described sleeve inner is provided with the tapered connecting bolt of front end and inwall is established threaded cylinder, the tapering maximum of described connecting bolt leading section, the front end of described cylinder is expand tube shape, described cylinder and connecting bolt are spirally connected, the rearward end of described connecting bolt stretches into the front end of cylinder, and stretch out cylinder from the rearward end of cylinder, the rearward end of connecting bolt is stretched out sleeve by through hole subsequently, and be spirally connected in nut, described nut press seal end.
The end outer wall of the front end of described cylinder is provided with flange.
Described cylinder one end is provided with peep hole.
Described connecting bolt end is provided with gripping section, and described gripping section outer surface is flat
The beneficial effects of the utility model are: 1, in being rotationally connected one end of bolt, the other end of connecting bolt is departed under the effect of contrary power with attachment; 2, more stable in the process that is arranged so that dismounting of sleeve, avoided connecting bolt to break simultaneously; 3, peep hole be arranged so that more easily to observe unloading process, in the time that sleeve does not overlap with the center line of connecting bolt, adjust in time simultaneously; 4, the setting of the gripping section of connecting bolt end, makes spanner convenient in the process of clamping, has avoided connecting bolt to rotate along with the rotation of nut.
Brief description of the drawings
Fig. 1 is the structural representation of semiaxis and bearing disassembling device;
Fig. 2 is the structural representation of bearing outer ring provision for disengagement.
Detailed description of the invention
A kind of semiaxis and bearing disassembling device as shown in Figure 1, comprise sleeve 1, sleeve 1 one end is sealed end, the other end is provided with several peep holes 6, by being set, can check in the process of semiaxis and bearing removal peep hole 6, semiaxis stretches out the situation of bearing, preferably 6 of the quantity of peep hole 6, end at sleeve 1 is uniformly distributed, on sealed end, be provided with through hole 4, be provided with connecting bolt 3 and cylinder 2 in sleeve 1 inside, described cylinder 2 inwalls are provided with screw thread, the rear end of cylinder 2 is expand tube shape, be that rear end is the increasing taper of tapering, rearward end tapering maximum, and rearward end is provided with several otch, the rearward end of described connecting bolt 3 is provided with the gripping section that outer surface is flat, thereby be easy to fixing connecting bolt 3, the leading section of connecting bolt 3 stretches into the rear end of cylinder 2, and be spirally connected with the middle part of cylinder 2, the front end of cylinder 2 is hollow form, sleeve 1 is stretched out by through hole 4 in the rear end of connecting bolt 3, and be spirally connected with nut 5, the sealed end of described nut 5 clamp sleeves 1.
In the process of semiaxis and bearing removal, the end of the rear end of cylinder 2 and semiaxis is spirally connected, the end that sleeve 1 is provided with peep hole 6 compresses bearing, utilize the gripping section of spanner clamping connecting bolt 3, utilize another spanner rotating nut 5, in the process of rotating nut 5 simultaneously, connecting bolt 3 is to device rear motion, semiaxis also rotates backward under the rotation of cylinder 2, thereby screws in cylinder 2 middle parts, and semiaxis is removed from bearing the most at last.Connecting bolt 3 rearward end are provided with gripping section, and utilize spanner clamping gripping section, make the direction of rotation of connecting bolt 3 and nut 5, realize connecting bolt 3 to device rear motion.
Bearing outer ring provision for disengagement as shown in Figure 2, comprise sleeve 1, sleeve 1 one end is sealed end, the other end is provided with several peep holes 6, by being set, can check in the process of bearing outer ring dismounting peep hole 6, bearing outer ring departs from the situation of bearing, preferably 6 of the quantity of peep hole 6, end at sleeve 1 is uniformly distributed, on sealed end, be provided with through hole 4, be provided with connecting bolt 3 and cylinder 2 in sleeve 1 inside, described connecting bolt 3 front ends are tapered, and the tapering maximum of the leading section of connecting bolt 3, described cylinder 2 inwalls are provided with screw thread, cylinder 2 front ends are expand tube shape, be that front end is the increasing taper of tapering, leading section tapering maximum, leading section is provided with several longitudinal cuts, and leading section outer wall is provided with flange 7, the rearward end of described connecting bolt 3 is provided with the gripping section that outer surface is flat, thereby be easy to fixing connecting bolt 3, the front end of cylinder 2 is stretched in the rear end of connecting bolt 3, and stretch out cylinder 2 from the rearward end of cylinder 2, sleeve 1 is stretched out by through hole 4 in the rear end of connecting bolt 3 subsequently, and be spirally connected with nut 5, the sealed end of described nut 5 clamp sleeves 1.
