Abstract
The utility model discloses a disassembly and assembly tool special for a bearing outer ring, which comprises a steel cylinder, a bolt shaft, a gasket, a long bolt, a steel cylinder rotation rod and a nut, wherein the left end of the steel cylinder is opened, the right end of the steel cylinder is closed, and a closed end plate of the steel cylinder is provided with a hole with an axis coinciding with the axis of the steel cylinder; the left end of the bolt shaft is provided with a counter bore with an axis coinciding with the axis of the bolt shaft, and the side wall of the bolt shaft is provided with at least four slotted holes which are opened at the left sides; the bolt shaft passes through the hole at the closed end of the steel cylinder, the bolt shaft has a clearance fit with the hole at the closed end of the steel cylinder, and the end of the bolt shaft, which passes through the steel cylinder, is provided with the nut by mating; the left end of the long bolt is provided with a cone; and the long bolt has a screw-thread fit with a thread hole on the middle part of the bolt shaft. The disassembly and assembly tool special for the bearing outer ring has the advantages that the slotted holes arranged on the side wall of the counter bore at the left side of the bolt shaft can be expanded under the action of the left cone of the long bolt, and after the slotted holes are expanded, the inner side of the bearing outer ring is extruded, so that the bearing outer ring can be easily pulled out only by rotating the nut so as to prevent mechanical shocks from damaging the inner wall of a shell.
Description
Technical field
The utility model relates to the bearing dismantling technical field.
Background technology
Bearing wear in industrial wheeled equipment speed changer and the rear axle differential will be planted and ball when damaging; Need more renew bearing, because old bearing outer ring remains in the housing, and bearing adopts interference fit between its outer ring and the housing in installation process; After using after a while; Inlay more firmly, adopt common dismounting mode to be difficult to, but also have the risk of damaging inner walls its complete dismounting.
The utility model content
The utility model technical problem to be solved provides the special-purpose dismantling device of a kind of bearing outer ring, adopts screw rod to rotatablely move and is transformed into rectilinear motion, easily with the complete dismounting of bearing outer ring, and does not damage inner walls, and operating efficiency is high.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: the special-purpose dismantling device of a kind of bearing outer ring comprises steel cylinder, bolt shaft, pad, stay bolt, steel cylinder dwang and nut; Said steel cylinder left end is uncovered, and right-hand member sealing and its Closed end plate are provided with the hole of axis and steel cylinder dead in line; Said bolt shaft left end is provided with the counterbore of axis and bolt shaft dead in line and the long slot bore that its sidewall is provided with left side, at least four roads opening; Said long slot bore is evenly arranged around the bolt shaft axis; The right section of said bolt shaft is provided with external screw thread and is provided with axis and the screwed hole of bolt shaft dead in line, and screwed hole is communicated with said counterbore; Hole setting and bolt shaft that said bolt shaft is passed the steel cylinder blind end cooperate with the interporal lacuna of being located at the steel cylinder blind end, and said bolt shaft is passed the supporting nut that is provided with of steel cylinder one end; Said stay bolt left end is provided with cone and the cone small end is connected with the stay bolt body-fixed; Said stay bolt and bolt shaft middle part screwed hole threaded engagement, and the supporting primary nut that is provided with of right-hand member.
Be arranged with two steel cylinders rotation rod members on the said steel cylinder outer wall with its axis normal.
Said nut left side is provided with circular step.
Said bolt shaft right-hand member is set to the square head structure.
Adopt the beneficial effect that technique scheme produced to be: on the counterbore sidewall of thread spindle left side long slot bore to be set and under the cone effect of stay bolt left side, can to expand; The back extrusion axis bearing outer-ring that expands is inboard; Only need can bearing outer ring easily be pulled out through the rotation nut; Abandon existing impact type method for dismounting, prevent mechanical shock damage inner walls.The special-purpose dismantling device of the bearing outer ring that simultaneously the utility model disclosed can also reverse installation shaft bearing outer-ring, shortens engineering mechanical maintenance maintenance period greatly.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the utility model structural representation;
In the accompanying drawings: 1, bearing outer ring; 2, steel cylinder; 3, bolt shaft; 4, pad; 5, stay bolt; 6, steel cylinder rotates rod member; 7, nut; 8, bolt shaft square head; 9, primary nut.
The specific embodiment
The special-purpose dismantling device of a kind of bearing outer ring as shown in Figure 1 comprises steel cylinder 2, bolt shaft 3, pad, stay bolt 5, steel cylinder 2 dwangs and nut 7; Said steel cylinder 2 left ends are uncovered, and right-hand member sealing and its Closed end plate are provided with the hole of axis and steel cylinder 2 deads in line; Said bolt shaft 3 left ends are provided with the counterbore of axis and bolt shaft 3 deads in line and the long slot bore that its sidewall is provided with left side, at least four roads opening; Said long slot bore is evenly arranged around bolt shaft 3 axis; Said bolt shaft 3 right sections are provided with external screw thread and are provided with axis and the screwed hole of bolt shaft 3 deads in line, and screwed hole is communicated with said counterbore; Hole setting and bolt shaft 3 that said bolt shaft 3 is passed steel cylinder 2 blind ends cooperate with the interporal lacuna of being located at steel cylinder 2 blind ends, and said bolt shaft 3 is passed the supporting nut 7 that is provided with of steel cylinder 2 one ends; Said stay bolt 5 left ends are provided with cone and the cone small end is connected with stay bolt 5 body-fixed; Said stay bolt 5 and bolt shaft 3 middle part screwed hole threaded engagement, and the supporting primary nut 9 that is provided with of right-hand member.
Be arranged with two steel cylinders rotation rod members 6 on said steel cylinder 2 outer walls with its axis normal.
Said nut 7 left sides are provided with circular step.
Said bolt shaft 3 right-hand members are set to the square head structure.
In concrete application process, pass bolt shaft from the steel cylinder center nut 7 of screwing on earlier; Make the circular step and the steel cylinder section through hole in nut 7 left sides form matched in clearance; Penetrate stay bolt 5 from the bolt shaft left end again, and precession, know that it passes from the bolt shaft right-hand member; The primary nut of screwing on, the assembling of completion instrument.
When the dismounting bearing outer ring, the dextrorotation primary nut makes the bolt shaft left end constantly open, and up to fully contacting with bearing outer ring is inboard, the dextrorotation big nut outwards moves bolt shaft, thereby draws bearing outer ring late to come then.Utilize the utility model can solve effectively the dismounting bearing outer ring and the blind hole lining is time-consuming, the effort problem.
