Abstract
An axle box bearing outer ring disassembling device comprises a fixing plate, wherein a through hole is arranged at the center of the fixing plate, a threaded sleeve corresponding to the through hole is fixed on the rear face of the fixing plate, the front part of a screw bolt matching with the threaded sleeve passes through the through hole in the fixing plate and is in running fit with the through hole, a press plate is arranged on the screw bolt in front of the fixing plate, the front part of the screw bolt is stage-shaped and has a stage-shaped surface opposite to the rear face of the fixing plate, and a handle is arranged on the rear end of the screw bolt. As the utility model with simple structure adopts a screw drive method to press a bearing outer ring out of an axle box through the press plate which applies a static pressure on the bearing outer ring, the utility model is capable of disassembling the rolling bearing outer ring in the axle box conveniently and ensuring that the bearing outer ring is removed from the axle box without damage. In addition, the screw bolt and the press plate are connected through a bearing seat and a bearing and the handle has an appropriate length, thereby bringing about easy operation.
Description
Technical field
The utility model relates to the provision for disengagement of axle box bearing outer ring.
Background technology
In when repairing the locomotive axle box, the housing washer in the axle box and ball need be pulled down and clean, what take at present is that method with hammering splits out the outer ring in axle box, both caused the damage of bearing easily, and working strength of workers is big.
The utility model content
The purpose of this utility model is to propose a kind of convenience, bearing outer ring is not split out next axle box bearing outer ring provision for disengagement with easily, being damaged from axle box.
For achieving the above object, the utility model comprises fixed head, fixed head central authorities are provided with through hole, corresponding through hole is fixed with swivel nut on the fixed head trailing flank, the screw rod front portion that cooperates with swivel nut by the through hole on the fixed head and and through hole between movingly, be provided with pressing plate on the screw rod and in the front side of fixed head, the front portion of screw rod is stepped, the trailing flank of the relative pressing plate of its cascaded surface, the rear end of screw rod is provided with handle.
On the described screw rod and the place ahead that is in cascaded surface is provided with bearing block, be provided with bearing in the bearing block, be in screw rod on the fixed head and be provided with cannelure on every side, bearing block and screw rod cannelure are movingly, be provided with cannelure on the trailing flank of pressing plate and around being in screw rod, bearing embeds in the pressing plate cannelure.
The position that described screw front end stretches out pressing plate is provided with the nut that pressure guard comes off.
Described pressing plate has trident, the marginal trough of every fork.
Described fixed head two ends are provided with installing hole.
The utility model is simple in structure, what adopt is that screw drive mode extrudes it the method that bearing outer ring applies static pressure by pressing plate from axle box, thus utilize housing washer in the utility model dismounting axle box easy to operate, guarantee that bearing outer ring does not split out with not being damaged from axle box.Owing to is connected with bearing by bearing block between screw rod and the pressing plate, add suitable decreased food again, so operation is light.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is the configuration diagram of embodiment 1;
Fig. 2 is the diagrammatic sketch of pressing plate.
The specific embodiment
Embodiment
Fig. 1 and embodiment shown in Figure 2 comprise fixed head 1, and fixed head 1 central authorities are provided with through hole 1-1, and two ends are provided with installing hole 1-2.Corresponding through hole 1-1 is fixed with swivel nut 2 on fixed head 1 trailing flank, the screw rod that cooperates with swivel nut 23 anterior by the through hole 1-1 on the fixed head 1 and and through hole 1-1 between movingly, be provided with pressing plate 4 on the screw rod 3 and in the front side of fixed head 1, the front portion of screw rod 3 is stepped, on the screw rod 3 and the place ahead that is in cascaded surface 3-1 is provided with bearing block 8, be provided with bearing 7 in the bearing block 8, be provided with cannelure 3-2 around being in screw rod 3 on the fixed head 1, bearing block 8 and screw rod cannelure 3-2 are movingly, be provided with cannelure 4-1 on the trailing flank of pressing plate 4 and around being in screw rod 3, bearing 7 embeds among the pressing plate cannelure 4-1.
The rear end of screw rod 3 is provided with handle 5.The position that screw rod 3 front ends stretch out pressing plate 4 is provided with the nut 6 that pressure guard 4 comes off.
When present embodiment uses, fixed head 1 is connected on the axle box by two bolts, turning handle, screw rod 3 advances while rotating and drives bearing block 8 and bearing 7 advances, because bearing 7 embeds among the pressing plate cannelure 4-1, screw rod 3 promotes pressing plate 4 by bearing 7 and advances, the land area of pressing plate 4 enters in the bearing outer ring that needs in the axle box to dismantle, sunk area 4-2-1 is pressed on the bearing outer ring that needs dismounting, be rotated further handle 5, because the bearing inner race hoop that needs to dismantle in the axle box is on the axle box axle, pressing plate 4 extrudes the axle box bearing outer ring.
In the foregoing description, can not use bearing block 8 and bearing 7, the cascaded surface 3-1 of screw rod 3 directly touches the trailing flank of pressing plate 4, promotes pressing plate 4 by screw rod 3 while rotating and advances, but need bigger external force.
