Description

Technical Field

[0001] This utility model belongs to the field of maintenance tool technology and relates to a multifunctional bearing puller. Background Technology

[0002] During motor maintenance, bearings need to be disassembled to inspect the components behind them. However, on-site bearing disassembly requires different tools due to the variety of bearing models, reducing efficiency. Furthermore, existing tools can damage the bearing structure, forcing the replacement of bearings that wouldn't otherwise need replacing. This undoubtedly wastes resources and increases production costs. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the prior art by providing a multifunctional bearing puller, which solves the problems of needing to constantly change disassembly tools when disassembling different types of bearings, reducing work efficiency, and easily causing damage to the bearings during the disassembly process.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] A multifunctional bearing puller includes a front baffle and a rear baffle, which are connected by a pull rod. The front baffle has an opening on its side, which is semi-circular. The surface of the front baffle has symmetrically arranged pull rod holes, and a first stop block is provided in each pull rod hole, and the two are movably connected. The end of the pull rod is inserted into the pull rod hole and contacts the first stop block. The surface of the front baffle also has a second stop block, which includes two arc-shaped plates, and the ends of both plates are dampedly connected to the front baffle.

[0006] Furthermore, the two arc-shaped plates can be arranged in a circle.

[0007] Furthermore, the rear baffle is identical in shape and size to the front baffle.

[0008] Furthermore, the pull rod is made of round steel with a length of 1~2m and a diameter of 20~50mm, and its two ends are provided with threads with a length of 300mm.

[0009] Furthermore, the opening directions of the rear baffle and the front baffle are the same.

[0010] The beneficial effects of this utility model are as follows:

[0011] This invention can be applied to different types of bearings during use, reducing the need to change disassembly tools and improving work efficiency; moreover, the disassembly process can ensure that the bearing is not damaged, thus reducing production costs. Attached Figure Description

[0012] Figure 1 This is an exploded view of a component of this utility model.

[0013] In the diagram, 1-pull rod, 2-front baffle, 3-first stop block, 4-second stop block, 5-rear baffle, 6-pull rod hole. Detailed Implementation

[0014] The technical solution of this utility model will be described below with reference to the accompanying drawings and implementation methods.

[0015] like Figure 1 As shown, a multifunctional bearing puller includes a front baffle 2 and a rear baffle 5. The rear baffle 5 has the same shape and size as the front baffle 2, and the two are connected by two pull rods 1. The opening directions of the rear baffle 5 and the front baffle 2 are the same. Specifically, the pull rod 1 is made of round steel with a length of 1m and a diameter of 20mm, and its two ends are provided with threads with a length of 300mm.

[0016] The front baffle 2 has an opening on its side, which is semi-circular. The surface of the front baffle 2 has symmetrically arranged pull rod holes 6, and a first stop block 3 is installed in the pull rod hole 6, and the two are movably connected. The end of the pull rod 1 is inserted into the pull rod hole 6 and contacts the first stop block 3. The surface of the front baffle 2 also has a second stop block 4 for adjusting the inner diameter of the bearing. The second stop block 4 includes two arc-shaped plates, and the ends of both are dampedly connected to the front baffle 2. The two arc-shaped plates can be arranged in a circle, and they hold more than half of the area of ​​the inner ring of the bearing. The force-bearing area of ​​the inner ring of the bearing is increased, so the bearing can be removed without damage.

[0017] In use, the two pull rods 1 are placed on both sides of the jack as the main force-bearing components, the rear baffle 5 is used to support the bottom of the jack, and the front baffle 2 is placed on the side of the bearing to be disassembled. By adjusting the distance between the front baffle 2 and the rear baffle 5, the bearing can be disassembled without damage.
