Abstract
The utility model discloses a bearing disassembling tool. The bearing disassembling tool comprises a supporting frame, a pressing plate and an annular tray which are arranged in sequence, wherein the pressing plate is matched with the end surface of a main shaft, the annular tray is matched with a bearing and is composed of at least two annular splits, the adjacent annular splits are fixedly connected in a detachable mode, an annular step hole matched with the outer cylindrical surface and the end surface of the bearing is formed in the annular tray, the annular tray is connected with the supporting frame through threaded rods, the supporting frame is in threaded connection with a drawing bolt coaxial with the annular step hole, and the drawing bolt and the pressing plate are matched in a single-freedom-degree rotation mode. According to the bearing disassembling tool, the bearing is supported through the annular tray, the end surface of the main shaft is pressed through the pressing plate, then the drawing bolt is rotated, due to the fact that the force used for drawing the bearing is parallel with the axial direction of the main shaft, the situation that the bearing locks the main shaft in the drawing process can be avoided, it is ensured that the main shaft is not damaged, and drawing operation is simple and convenient.
Description
Technical field
The utility model relates to a kind of instrument, particularly a kind of instrument of dismantling bearing.
Background technology
In prior art, when main shaft is dismantled bearing, general employing beaten bearing or used the mode of shaft bearing replacer to dismantle.Knocking dismounting is axially very large to main shaft injury; can protect to a certain extent main shaft although adopt shaft bearing replacer; but because the axial thrust that existing shaft bearing replacer applies bearing often can not be coaxial with main shaft; also usually there is the situation of bearing locking main shaft in detachable, also more serious to the damage of main shaft precision.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of bearing extractor, damages the problem of main shaft to solve in prior art while dismantling bearing.
The utility model bearing extractor, comprises successively the support of arranging, the pressing plate coordinating with main shaft end face and the annular pallet with bearing fit;
Described annular pallet is at least made up of two ring lobes, and adjacent ring lobe is detachable to be fixedly connected with, and on annular pallet, is provided with the ring-shaped step hole coordinating with bearing top circle cylinder and end face, and described annular pallet is connected with support by screw rod;
The drawing bolt coaxial with ring-shaped step hole that be threaded on described support, described drawing bolt and pressing plate single-degree-of-freedom are rotatably assorted.
Further, described adjacent ring lobe connects by joint bolt.
Further, on one end that described screw rod is connected with annular pallet, be provided with stop nut.
The beneficial effects of the utility model:
The utility model bearing extractor, hold bearing by annular pallet, push down main shaft end face by pressing plate again, then rotate drawing bolt, due to power and the main shaft axially parallel of drawing bearing, therefore the situation of bearing locking main shaft can avoid drawing time, guarantee that main shaft is not damaged, and drawing is simple to operation.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model bearing extractor;
Fig. 2 is the three-dimensional view of the utility model bearing extractor.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the present embodiment bearing extractor, comprises successively the support 1 of arranging, the pressing plate 2 coordinating with main shaft end face and the annular pallet 3 with bearing fit;
Described annular pallet 3 is made up of (certainly in different embodiment two ring lobes, described annular pallet 3 also can be made up of two above ring lobes, form as encircled lobes by three or four), adjacent ring lobe is detachable to be fixedly connected with, and on annular pallet 3, be provided with the ring-shaped step hole 4 coordinating with bearing top circle cylinder and end face, described annular pallet 4 is connected with support 1 by screw rod 5;
The drawing bolt 6 coaxial with ring-shaped step hole 4 that be threaded on described support 1, described drawing bolt 6 is rotatably assorted with pressing plate 2 single-degree-of-freedoms.
In the time of work, the present embodiment bearing extractor is held bearing by the ring-shaped step hole 4 on annular pallet 3, push down main shaft end face by pressing plate 2 again, then rotate drawing bolt 6, due to power and the main shaft axially parallel of drawing bearing, therefore the situation of bearing locking main shaft can avoid drawing time, can guarantee that main shaft is not damaged, and drawing is simple to operation.
As the improvement to the present embodiment, described adjacent ring lobe connects by joint bolt 7, and the easy accessibility of adjacent ring lobe can improve bearing removal operating efficiency.
As the improvement to the present embodiment, on one end that described screw rod 5 is connected with annular pallet 3, be provided with stop nut 8, can guarantee that by stop nut 8 annular pallet 3 can not become flexible in drawing process, can further guarantee can not damage in unloading process main shaft.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
