Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of dismounting tool for bearing outer ring, saves the working time, reduce labour intensity, improve operating efficiency.
For achieving the above object, the utility model adopts following technical scheme:
A kind of dismounting tool for bearing outer ring, it comprises urceolus and push rod, described urceolus is the sleeve that through hole is offered at a center, the lateral wall of sleeve one end is arranged the steel ball of multiple circumference uniform distribution, described push rod is coaxially installed in the through hole of urceolus, the outer wall that push rod and steel ball are abutted against is set to the second inclined-plane, and the length of push rod is greater than the length of urceolus.
Above-mentioned dismounting tool for bearing outer ring, the profile of described urceolus is a multidiameter, and described steel ball is arranged on the large end port of urceolus, and the through hole of urceolus is set to the shoulder hole identical with profile, and the madial wall arranging the end of steel ball is the first inclined-plane.
Above-mentioned dismounting tool for bearing outer ring, sheathed first nut of small end of urceolus, the inner side of described first nut arranges packing ring.
Above-mentioned dismounting tool for bearing outer ring, equipped second nut in the one end away from steel ball of described push rod, the appearance and size of described second nut is greater than the aperture of urceolus small end.
The beneficial effects of the utility model are:
The utility model structure is simple, for dismantling the bearing outer ring of pedestal inner chamber being set in limited space, long and narrow mechanism, saving the working time, reducing labour intensity, improve operating efficiency.Push rod is installed in urceolus, urceolus stretches in pedestal inner chamber, utilize rolling groove bearing outer ring inwall assembling rolling element, make the outer end of the steel ball of setting-in on urceolus enter in the rolling groove of bearing outer ring, the outer wall that push rod and steel ball are abutted against is set to inclined-plane, by radially outward pushing up steel ball, prevent steel ball from moving inward, push rod moves axially to the direction away from pedestal inner chamber in urceolus, firmly promptly bearing outer ring, for convenience detachly extracts.
At the sheathed packing ring of urceolus end and the first nut, abutted against by packing ring and pedestal, equipped second nut on push rod, second nut and urceolus phase apical grafting, adjusted the relative displacement of push rod and urceolus by precession second nut, radial direction holds out against steel ball, reduces labour intensity.The madial wall that urceolus arranges steel ball is set to the first inclined-plane, corresponding with the second inclined-plane of push rod equipped.

Detailed description of the invention
Referring to Fig. 1, a kind of dismounting tool for bearing outer ring described in the utility model, is mainly used in the pedestal inner chamber dismounting bearing outer ring in limited space, long and narrow mechanism.Dismounting tool for bearing outer ring comprises urceolus 1, push rod 2, first nut 4 and the second nut 6.Described push rod 2 is installed in urceolus 1, and the first nut 4 is fitted in the end of urceolus 1, and the second nut 6 is fitted in the end of push rod 2.
Described urceolus 1 is a sleeve, and the profile of sleeve is a multidiameter, and the small end periphery of multidiameter arranges screw thread.Run through at the center of sleeve and arrange through hole, through hole is set to the shoulder hole identical with profile.Run through in the port radial direction of the large end of multidiameter and offer multiple installing hole, described installing hole is along the circumferential direction distributed on sidewall.All be embedded with steel ball 3 in each installing hole, a part for described steel ball 3 is positioned at the outside of urceolus 1; Another part is in the inner side of urceolus 1.The madial wall place being provided with the urceolus 1 of steel ball 3 is set to the first inclined-plane 1-1, and the angle of described first inclined-plane and axis is the value of α, α is 15 °---and 45 °.
Described first nut 4 is sleeved on the small end of urceolus 1, is fixedly linked by screw thread and urceolus 1, according to length adjustment first nut 4 of cavity outer wall and bearing outer ring 8 in pedestal 7 axial location at urceolus 1.Packing ring 5 is set in the inner side of the first nut 4, is offseted by the outer wall of packing ring 5 with pedestal in use procedure, prevent friction impaired, increase the service life.
Described push rod 2 is installed in the through hole of urceolus 1, coaxially arranges with urceolus 1, and can move freely vertically in urceolus 1.The length of push rod 2 is greater than the length of urceolus 1, the termination of the corresponding one end of the large end with urceolus 1 is provided with plunger tip, the periphery of described plunger tip is set to the second inclined-plane 2-1, the outer wall of described second inclined-plane 2-1 and the first corresponding 1-1 in inclined-plane, the second inclined-plane 2-1 and steel ball 3 phase apical grafting.
Described second nut 6 is fitted in the end of push rod 2, namely away from one end of steel ball 3, is fixedly connected with by screw thread with push rod 2.The appearance and size of the second nut 6 is greater than the aperture of urceolus 1 small end, and the inner side of the second nut 6 is abutted against mutually with the small end of urceolus 1.
Using method of the present utility model is:
Referring to Fig. 2, adjust the axial location of the first nut 4 at urceolus 1 according to the outer wall of the inner chamber of pedestal 7 and the distance of being separated by of bearing outer ring 8, steel ball 3 should be a bit larger tham the distance of the outer wall of bearing outer ring 8 and pedestal 7 with the distance of packing ring 5.Penetrated by steel ball 3 one end by push rod 2, after being placed in urceolus 1, push rod and urceolus stretch into the inner chamber of pedestal 7 simultaneously.
Rotate urceolus 1, make the steel of setting-in on urceolus, the outer end of 3 enters in the rolling groove of bearing outer ring 8, and now slight inwardly precession first nut 4, makes packing ring 5 offset with the outer wall of pedestal 7 inner chamber.Inside precession second nut 6, makes the second inclined-plane 2-1 of push rod 1 closely be abutted against with steel ball 3 and pushes up mutually afterwards, by radially outward pushing up steel ball 3, makes steel ball 3 firmly grasp bearing outer ring 8 firmly.Hold with a firm grip afterwards urceolus 1 and push rod 2 outwards exerts a force, and drawing goes out bearing outer ring 8.
