Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Fig. 1 shows a kind of mud bearing extractor of the utility model and uses the structure cross-sectional schematic;
Fig. 2 shows A among Fig. 1 to cross-sectional schematic.
The specific embodiment
As Fig. 1 and shown in Figure 2, the utility model comprises securing bracket 1, removal bracket 2 and thrust stand 3.Wherein, securing bracket 1 is used for fixing connecting axle 4, and removal bracket 2 is used for connection bearing 5, and thrust stand 3 is used for applied thrust, makes bearing 5 take off from axle 4 and resigns from office.
Securing bracket 1 one end fixed connection shafts 4, the other end flexibly connects thrust stand 3.It is convenient, reliable that securing bracket 1 and axle 4 are connected need, do not break down in unloading process guaranteeing.Relative motion can take place with thrust stand 3 in securing bracket 1, thereby thrust is passed.
The removal bracket 2 one ends bearing 5 that is connected, the fixedly connected thrust stand 3 of the other end.Removal bracket 2 is connected with bearing 5 to be needed fast reliably, and has certain intensity.Removal bracket 2 is fixedlyed connected with thrust stand 3, the thrust on the thrust stand 3 effectively can be delivered on the bearing 5.
The utility model adopts securing bracket 1, removal bracket 2 and thrust stand 3, by securing bracket 1 fixed connection shaft 4, by removal bracket 2 clamping bearings 5, pass through thrust stand 3 again to securing bracket 1 and removal bracket 2 applied thrusts, move back thereby force bearing 5 to take off, use the utility model can make that bearing 5 is stressed even, breakage can not take place from axle 4, and simple and quick, operating efficiency improves greatly.
In the utility model, securing bracket 1 one ends are by the axle 4 that is threaded, and the other end is by the thrust stand 3 that is threaded.On axle 4, offer thread groove 41, the external screw thread 11 that matches at securing bracket 1 one end settings and this thread groove 41.Securing bracket 1 other end is an internal thread 12, the convenient thrust stand 3 that connects.For guaranteeing carrying out smoothly of mud bearing 5 dismountings, securing bracket 1 two ends screw thread 11,12 should meet the bonding strength requirement.
In the utility model, removal bracket 2 comprises interconnective screw rod 21 and cutting ferrule 22, and screw rod 21 connects thrust stand 3 position-movablely, cutting ferrule 22 clamping bearings 5.Usually screw rod 21 is set to 4, is symmetrical arranged, to guarantee that thrust is even.Cutting ferrule 22 can adopt two semi-loops, by connector 23 two semi-rings is fixed together.On the cutting ferrule 22 catching is set, corresponding draw-in groove is set on bearing 5, to realize quick clamping.
