The utility model relates to a bearing dismantlement technical field especially relates to a bearing extracting tool.
In the prior art, the bearing on the rotor rotating shaft is usually dismounted by means of outward beating or drawing, but when the rotor rotating shaft is long, the traditional puller cannot be operated due to limited application range, if other lengthened dismounting tools are adopted, the rotating shaft can be bent and scrapped due to stress, the stress of the outer ring of the bearing is uneven, the dismounted bearing is damaged, and the bearing cannot be reused.
The utility model discloses a chinese patent document discloses a utility model patent of "a bearing dismantles frock" (CN207495397U), to prior art have in the in-process of dismantling the bearing skid, fish tail bearing scheduling problem, this utility model's main core is: three fixed plates connected by a movable plate are fixed on the inner side of the bearing ring in an encircling manner, a jacking screw rod for connecting the fixed plates and the panel is adjusted, the distance between the fixed plates and the panel is shortened, and the fixed plates drive the bearing ring to slowly break away from the bearing ring outwards, so that the separation of bearing parts is realized.
The above-mentioned publication has many defects while solving the related technical problems, one of them is that three movable plates connect two adjacent fixed plates two by two for connecting the remaining parts into a ring to be sleeved on the shaft body provided with the bearing, for requiring to connect six screws, which results in large assembly workload, and in addition, because the movable plates and the fixed plates are connected at specific positions, the operation space is limited, which will seriously affect the dismounting effect of the bearing; and secondly, due to the limitation of axial and radial spaces, sometimes there is no space for connecting the movable plate and the fixed plate, even when the bearing shown in the attached drawing is not a thrust roller bearing, if the above scheme is adopted, the screw rod and the movable plate arranged on the bearing cannot avoid the bearing outer ring and the retainer, so that the movable plate and the fixed plate cannot be installed, even if there are installation spaces in the axial and radial directions, the axial external force is applied to the outer ring and the retainer when the installed device is used, and even if the bearing is taken down, the bearing can be damaged and cannot be used continuously.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a bearing extracting tool, and can avoid dismantling the deformation or the damage of in-process pivot, bearing.
In order to realize the purpose, the utility model discloses a following technical scheme, a bearing extracting tool, but including an interior chuck of joint on the inboard axle body of bearing, be provided with the U-shaped breach that link up the face in the quotation of interior chuck, U-shaped breach oral area extends to the quotation department, the bottom is located the quotation middle part.
In the above scheme, the disc surface of the inner chuck is provided with a U-shaped notch penetrating through the disc surface, the inner chuck can be conveniently clamped on the shaft body at the inner side of the bearing through the U-shaped notch, in order to ensure that the bearing is dismounted without damage, the opening width of the U-shaped notch can be set to be in a size matched with the diameter of the shaft, the disc surface of the inner chuck is ensured to be axially displaced under the state of being attached to the inner ring of the bearing, and the bearing is dismounted.
FIG. 1 is a schematic structural view of an inner chuck according to the present invention;
FIG. 2 is a schematic structural view of the preferred embodiment 1 in use;
FIG. 3 is a schematic structural view of preferred embodiment 1;
FIG. 4 is a schematic structural view of an outer disk of the preferred embodiment 1;
FIG. 5 is a schematic view of the structure of the preferred embodiment 2 in use.
FIG. 6 is a schematic structural diagram of the outer disk of the preferred embodiment 2.
A bearing extracting tool as shown in fig. 1, including an inner chuck 10 that can joint on the bearing a inboard shaft body, be provided with the U-shaped breach 11 that link up the face on the quotation of inner chuck 10, U-shaped breach 11 oral area extends to the quotation border, and the bottom is located the quotation middle part. Interior chuck 10 passes through the joint of U-shaped breach 11 on the shaft body, and the quotation laminating is inboard at bearing A, with the help of traditional instrument (for example drawing the ware) axial outwards pulling interior chuck 10, drives bearing A and produces axial displacement, realizes bearing A's dismantlement. The inner chuck 10 designed by the invention can be quickly and conveniently clamped on the rotating shaft and is arranged at the end surface of the inner side of the bearing A, external force directly acts on the chuck body of the inner chuck 10 without the phenomenon of bearing outer ring stress, and axial displacement relative to the rotating shaft caused by bearing inner ring stress is at least ensured, so that the purpose of bearing disassembly is realized.
Aiming at the situation that the position of the bearing A on the rotating shaft is arranged, such as the distance between the bearing A and the shaft end, the invention provides the following two preferable schemes for realizing the scheme of applying the external force to the inner chuck 10:
in an optimal scheme 1, referring to fig. 1-4, a connecting hole 12 penetrating through the plate surface and arranged circumferentially is formed in the disc surface of the inner chuck 10, in order to apply an axial force to the inner chuck 10 to achieve axial displacement movement of the drive bearing a, the dismounting tool further comprises an outer disc 20 clamped or sleeved on the shaft body outside the bearing a, a hole 21 penetrating through the plate surface and arranged circumferentially is formed in the disc surface of the outer disc 20, and 3-8 connecting holes 12 and the holes 21 are respectively formed and are used for allowing bolts 30 to penetrate and connect when facing each other.
The outer disc 20 is clamped or sleeved on the rotating shaft and is positioned by using a shaft body step, the bolt 30 penetrates through the hole 21 and is matched with the connecting hole 12 to connect the inner chuck 10 and the outer disc 20, then the bolt 30 is screwed, and the distance between the inner chuck 10 and the outer disc 20 is reduced, and simultaneously the bearing A is driven to move towards the shaft end so as to be pulled out; the scheme that the outer disc 20 and the inner chuck 10 are matched with each other is selected, so that the tool cost can be reduced, and the special equipment is easier to adjust and more portable than special equipment such as drawing equipment.
Further, a round hole 22 is formed in the middle of the outer disc 20, and the outer disc 20 can be sleeved on the shaft body through the round hole 22 during specific implementation and can be positioned through a step of the shaft body.
Fig. 5 to 6 are preferred embodiment 2 of the present embodiment, which is different from the above preferred embodiment in that the shape of the outer disc 20 is different, the disc surface of the outer disc 20 is provided with holes 21 that penetrate through the disc surface and are circumferentially arranged, the connecting holes 12 and the holes 21 are respectively provided with 3 to 8 and are directly opposite to each other for the bolts 30 to penetrate through, except that the outer disc 20 is not provided with holes but directly abuts against the disc surface on one side on the shaft end; compared with the preferred scheme 1, the outer disc 20 directly abuts against one side disc surface on the end surface of the shaft outside the bearing A and is connected with the inner chuck 10 through the bolt 30.
Further, in order to arrange the bolt 30, the connection hole 12 is a screw hole, and the assembly efficiency is improved by providing the connection hole 12 as a screw hole.
