Abstract
The utility model discloses a bearing dismounting tool, it includes the lead screw base, processing has at least two screw holes on the lead screw base, it has at least two no. Two screw holes also to process on the convex cardboard, the lead screw constitutes threaded connection with no. Two screw holes of a threaded holes and simultaneously, processing has half circular clamping groove on the convex cardboard, half circular clamping groove cooperatees with the main shaft of installation bearing, the upper surface of convex cardboard and the contact of the lower extreme facial features of bearing, the jack is provided with between the lower terminal surface of top and the lead screw base of main shaft. This bearing dismounting tool can get off the bearing by convenient and fast from epaxial dismantlement, this dismouting device simple structure makes the convenience in addition, and it is convenient to use, can increase substantially the dismouting efficiency of bearing.
Description
Technical field
The utility model relates to a kind of attaching/detaching apparatus, particularly relates to a kind of bearing extractor.
Background technology
Existing bearing extractor (drawing horse) is general with two or three hooks, and two on hook bending positions need to bear very large tension.Screw mandrel rotation generation thrust and then the screw screw thread carried out on its hook seat of instrument of bearing removal is utilized easily to damage; And screw mandrel bears radial pressure, easily bending damage.
Utility model content
The purpose of this utility model is to provide a kind of bearing extractor, and bearing can convenient and swiftly disassemble from axle by this bearing extractor, and this attaching/detaching apparatus structure is simple, easily manufactured, easy to use, can increase substantially the dismounting efficiency of bearing.
In order to realize above-mentioned technical characteristic, the technical solution adopted in the utility model is: a kind of bearing extractor, it comprises screw mandrel base, leading screw base is processed with at least two screwed holes, convex clamp is also processed with at least two No. two screwed holes, form with a screwed hole and No. two screwed holes while of screw mandrel and be threaded, convex clamp is processed with semicircle draw-in groove, semicircle draw-in groove matches with bearings mounted main shaft, the upper surface of convex clamp contacts with the lower surface of bearing, jack is provided with between the top of main shaft and the lower surface of screw mandrel base.
Described screw mandrel is processed with external screw thread.
The described semi arch of semicircle draw-in groove matches with the outline of main shaft.
The utility model has following beneficial effect:
First semicircle draw-in groove is stuck on main shaft in use, and the upper surface of semicircle draw-in groove is contacted with the lower surface of bearing, again screw mandrel base is connected with convex clamp by screw mandrel, then jack is arranged between the upper end face of main shaft and screw mandrel base, start jack and will produce thrust between screw mandrel base and main shaft, because bearing is fixed by convex clamp, therefore under main shaft is subject to the thrust of jack, the inner ring generation relative motion with bearing is understood, thus make main shaft release bearing, finally reach the dismounting of bearing.
The utility model structure is simple, and bear pulling force large, the life-span is long, easy to use.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the utility model use procedure schematic diagram.
Fig. 2 is the utility model screw mandrel base front view.
Fig. 3 is the attached view of the utility model screw mandrel base.
Fig. 4 is the utility model convex clamp front view.
Fig. 5 is the utility model screw structure schematic diagram.
In figure: screw mandrel base 1, convex clamp 2, jack 3, screw mandrel 4, main shaft 5, bearing 6, screwed hole 101, semicircle draw-in groove 201, No. two screwed holes 202, external screw threads 401.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As Figure 1-5, a kind of bearing extractor, it comprises screw mandrel base 1, leading screw base 1 is processed with at least two screwed holes 101, convex clamp 2 is also processed with at least two No. two screwed holes 202, form with a screwed hole 101 and No. two screwed holes 202 while of screw mandrel 4 and be threaded, convex clamp 2 is processed with semicircle draw-in groove 201, semicircle draw-in groove 201 matches with the main shaft 5 installing bearing 6, the upper surface of convex clamp 2 contacts with the lower surface of bearing 6, and jack 3 is provided with between the top of main shaft 5 and the lower surface of screw mandrel base 1.
Further, by screw mandrel 4 screw mandrel base 1 fixed with convex clamp 2 and be connected, can ensure to keep motionless carrying out unloading process middle (center) bearing 6, and main shaft 5 is separated with the inner ring of bearing 6 under thrust, reaches the object of dismounting.
Further, a described screwed hole 101 and the position one_to_one corresponding of No. two screwed holes 202, and the quantity of screwed hole is at least two or more, thus ensure that the phenomenon of stripped thread can not appear in screwed hole because of under tension in unloading process.
Further, described screw mandrel 4 is processed with external screw thread 401.The quantity at least two or more of screw mandrel 4, multi-filament bar 4 can ensure that in disassembly process, screw mandrel can not deform.What in unloading process, screw mandrel 4 mainly bore is tension, and its ability of bearing tension is far longer than the ability of its compression, therefore, adopts said structure can extend screw mandrel service life.
Further, the semi arch of described semicircle draw-in groove 201 matches with the outline of main shaft 5.The arc size of semicircle draw-in groove 201 is greater than the radius of main shaft 5.
Specific operation process of the present utility model is:
First semicircle draw-in groove 201 is stuck on main shaft 5 in use, and the upper surface of semicircle draw-in groove 201 is contacted with the lower surface of bearing 6, again screw mandrel base 1 is connected with convex clamp 2 by screw mandrel 4, then jack 3 is arranged between the upper end face of main shaft 5 and screw mandrel base 1, start jack 3 and will produce thrust between screw mandrel base 1 and main shaft 5, because bearing 6 is fixed by convex clamp 2, therefore under main shaft 5 is subject to the thrust of jack 3, the inner ring generation relative motion with bearing 6 is understood, thus make main shaft 5 release bearing 6, finally reach the dismounting of bearing 6.
