[0006] In the foregoing frock for disassembling bearing on long axle, preferably, the first plate body is rectangular plate body, and the first semicircular slot is arranged on one side of the first plate body.
[0007] In the foregoing frock for disassembling bearing on long axle, preferably, the second plate body is rectangular plate body, and the second semicircular slot is arranged on one side of the second plate body.
[0008] In the foregoing frock for disassembling bearing on long axle, preferably, the first semicircular slot and the second semicircular slot have the same radius, and when the first plate body and the second plate body are combined, the first semicircular slot and the second semicircular slot form a circular hole.
[0009] In the foregoing frock for disassembling bearing on long axle, preferably, two threaded holes are arranged on the first plate body, the two threaded holes are located on the two sides of the first semicircular slot, and the two threaded holes extend along the length direction of the first plate body.
[0010] In the aforementioned tooling for disassembling the bearing on the long shaft, preferably, the second plate has two through holes, which are located on both sides of the two semi-circular grooves. Both through holes extend along the length of the second plate, and a bolt is installed in each of the two through holes. The bolts are threadedly connected to the threaded holes.
[0011] Compared with existing technologies, this utility model includes a first plate and a second plate. A first semi-circular groove is formed on the first plate, and a second semi-circular groove is formed on the second plate. The first and second plates are detachably connected. By setting up the first and second plates, this utility model allows the first and second plates to be combined in use. The first and second semi-circular grooves form a circular hole. After assembly, this utility model is installed on a long shaft. Then, by clamping the utility model in a vise and tapping the long shaft, the bearing can be removed. This effectively solves the problem of bearings on long shafts being unable to be removed using tensile tools, effectively ensuring maintenance efficiency. Attached Figure Description

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0018] Embodiments of this utility model: such as Figures 1-4 As shown, a tooling for disassembling bearings on a long shaft includes a first plate 1 and a second plate 2. A first semi-circular groove 3 is formed on the first plate 1, and a second semi-circular groove 4 is formed on the second plate 2. The first plate 1 and the second plate 2 are detachably connected.
[0019] Specifically, the first plate 1 is a rectangular plate, and the first semi-circular groove 3 is formed on one side of the first plate 1.
[0020] The second plate 2 is a rectangular plate, and the second semi-circular groove 4 is opened on one side of the second plate 2.
[0021] The first semicircular groove 3 and the second semicircular groove 4 have the same radius. When the first plate 1 and the second plate 2 are combined, the first semicircular groove 3 and the second semicircular groove 4 form a circular hole.
[0022] In this embodiment, the widths of the first plate 1 and the second plate 2 are equal. Both the first plate 1 and the second plate 2 are made of metal, such as stainless steel.
[0023] The first plate 1 has two threaded holes 5, located on both sides of the first semi-circular groove 3, and both threaded holes 5 extend along the length of the first plate 1. The second plate 2 has two through holes 6, located on both sides of the second semi-circular groove 4, and both through holes 6 extend along the length of the second plate 2. A bolt 7 is installed in each of the two through holes 6, and the bolt 7 is threadedly connected to the threaded hole 5.
[0024] Two through holes 6 are opposite to two threaded holes 5. The diameter of the through holes 6 is slightly larger than the diameter of the threaded holes 5, which facilitates the installation and removal of the two bolts 7.
[0025] The method of using this utility model is as follows: When the bearing on the long shaft cannot be disassembled using a pulling tool, install the first plate 1 and the second plate 2 onto the long shaft, ensuring that both the first plate 1 and the second plate 2 are located below the bearing. Insert two bolts 7 into the two through holes 6, and then rotate the bolts 7 to fix the first plate 1 and the second plate 2 together. The diameter of the circular hole formed by the first semi-circular groove 3 and the second semi-circular groove 4 should be equal to or greater than the diameter of the long shaft. Then, clamp the first plate 1 and the second plate 2 using a vise, and tap the shaft from the top of the long shaft to separate the shaft from the bearing. Using this application can effectively reduce damage during bearing removal and allows for quick bearing removal; the operation method is simple.
