Description

Technical Field

[0001] The utility model belongs to the technical field of bearing disassembly, and particularly relates to a bearing extractor. Background Art

[0002] A bearing extractor is a special tool for removing bearings. It is usually used in mechanical repair and maintenance to remove and replace worn bearings. The bearing extractor consists of one or more cylindrical bodies with inclined grooves. When used, the extractor gradually removes the bearing from the shaft through rotation and axial force. Existing bearing extractors have the following disadvantages:

[0003] 1. Difficult operation: Different bearing extractors are required for different bearing types, which is complicated to operate. Two different removers are required to directly remove bearings from the shaft and embedded bearings. The operation process is relatively complicated, resulting in low efficiency.

[0004] 2. Fragile bearings: If used improperly, the bearings may be damaged, such as scratches and deformation. Different types of bearings require different bearing extractors, which will increase the purchase cost of the tools.

[0005] In order to solve these problems, it is possible to consider designing a universal bearing extractor suitable for disassembling various types of bearings to improve efficiency and reduce operational difficulty. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-2As shown, the specific design of the above key components is described in detail below: the bearing extractor includes a threaded rod 1, a rotating head 2 is arranged above the threaded rod 1, a moving ring 14 is arranged on the threaded rod 1, a connecting head 8 is symmetrically arranged around the moving ring 14, a connecting plate 11 is arranged on the connecting head 8 through a hinge, a clamping mechanism is arranged below the connecting plate 11 through a screw 16, an extension plate 3 is symmetrically arranged around the moving ring 14, a plurality of drill holes 4 are opened on the extension plate 3, a vertical pull rod 4 is arranged on the drill hole 4, and a hinge The movable plate 9 includes a movable plate 9 and a movable shaft 10. One end of the movable plate 9 is in contact with the connecting head 8. The end of the movable plate 9 away from the connecting head 8 is connected to one end of the connecting plate 11. Two movable shafts 10 are provided. One movable shaft 10 is provided through the movable plate 9 and the connecting head 8. The other movable shaft 10 is provided through the movable plate 9 and the connecting plate 11. The clamping mechanism includes a clamping plate 12, a hole sleeve 13 and a plug rod 15. The clamping plate 12 is provided below the connecting plate 11 by means of a screw 16. The clamping plate is installed and removed by means of the screw 16. Installation and disassembly of 12, the hole sleeve 13 is opened on the card plate 12, the plug rod 15 is set in the card plate 12, and one end of the plug rod 15 is adjusted and limited by a bolt. A drill bit 5 is set below the threaded rod 1. First, determine the position of the disassembled bearing. If it is an embedded bearing disassembly, the card mechanism can be removed by removing the screw 16, and then the pull rod 4 is used for auxiliary disassembly to determine the size range of the bearing, select a suitable drill hole 4, put the pull rod 4 into the drill hole 4, and the position is limited by the bolt above the pull rod 4. And fix, after fixing the pull rod 4, align the pull rod 4 with the embedded bearing, align the drill bit 5 with the center of the bearing, and then pull out the embedded bearing by rotating the turntable 2. If it is a bare bearing on the shaft, it is necessary to unscrew the bolts and remove the pull rod 4, fix the clamping plate 12 and the connecting plate 11 with the screws 16, place the clamping plate 12 under the bearing, and make the hole sleeve 13 enclose the shaft under the bearing. After adjusting the position, use the insertion rod 15 to penetrate the clamping plate 12, and then screw the bolts into the insertion rod 15 to fix and limit the position.

[0024] The functions of each component are clear, the operation is simple and clear, and it is convenient for users to use and operate. The movable ring 14 and the connecting head 8 set on the threaded rod 1 can make the bearing extractor convenient to adjust the position and angle, improve the disassembly efficiency, and at the same time, the design of the drill bit 5 can more effectively remove the bearing. The clamping plate 12, the insertion rod 15 and the hole sleeve 13 in the clamping mechanism can adjust and limit the position, which can protect the bearing from damage and ensure the smooth progress of the disassembly process. The installation and disassembly of the clamping plate 12 achieved by the installation and disassembly of the screw 16 and the position of the insertion rod 15 adjusted by the bolt make the bearing extractor have better adaptability and adjustability, and can cope with bearings of different sizes and models, which can make the bearing removal process more convenient and quick, improve work efficiency, and at the same time protect the bearing from damage, and have better adaptability and adjustability. It should be noted that the insertion rod 15 and the pull rod 4 are both provided with threads at one end, and the end away from the thread is a smooth axial surface.
