[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.
[0023] The following describes a shallow groove idler bearing removal tool according to an embodiment of the utility model with reference to the accompanying drawings.
[0024] like Figure 1-4 As shown, an embodiment of the utility model proposes a shallow groove idler bearing removal tool, comprising: a support plate 3, a clamping arm 6 and a screw rod 2, wherein two sides of the same side of the support plate 3 are symmetrically fixedly connected with hinged parts; the clamping arm 6 has a first end and a second end, the first end of the clamping arm 6 is connected to the hinged part through a rotating shaft 9, and the second end of the clamping arm 6 has a hook body 61, and two clamping arms 6 are provided, and the two clamping arms 6 are rotatably connected to the corresponding two hinged parts respectively; the screw rod 2 is connected to the support plate 3 by a thread and passes through both sides of the support plate 3, the screw rod 2 has a first end and a second end, the first end of the screw 2 is fixedly connected with a nut 1, and the second end of the screw 2 is a clamping end for clamping the idler shaft 12, the first end of the screw rod 2 and the second end of the screw rod 2 are respectively located on both sides of the support plate 3, and the screw 2 is located in the middle of the support plate 3.
[0025] The embodiment of the utility model is provided with a clamping arm 6 and a screw rod 2, and the sleeve 13 is clamped by two clamping arms 6. The screw rod 2 is rotated with a wrench to make the pressing end of the screw rod 2 press against the idler shaft 12, and the screw rod 2 is continuously rotated to remove the sleeve 13 from the idler shaft 12. Since the outer ring of the idler bearing is fixedly connected with the sleeve 13, it is more convenient to remove the bearing 14 from the sleeve 13 after the sleeve 13 is removed. The disassembly tool is suitable for narrow working spaces, can reduce the safety hazards and working risks brought by replacing the idler bearing, reduce labor intensity, improve maintenance quality and work efficiency, reduce downtime for maintenance, and improve production efficiency.
[0026] Furthermore, the support plate 3, the clamping arm 6 and the screw rod 2 used in the embodiment of the utility model are all made of waste stainless steel scraps, and the material cost can be reduced by utilizing the waste.
[0027] In some embodiments, the clamping arms 6 are arc-shaped, and the second ends of the two clamping arms 6 are bent toward each other, so as to be more convenient to clamp the shaft sleeve 13.
[0028] In some embodiments, the hinged portion includes a first mounting plate 8, a second mounting plate 10 and a rotating shaft 9. The first mounting plate 8 and the second mounting plate 10 are fixed on the support plate 3 in parallel with each other. The first end of the clamping arm 6 is inserted into the gap between the first mounting plate 8 and the second mounting plate 10 and is rotatably connected through the rotating shaft 9. The rotating shaft 9 passes through the first mounting plate 8, the second mounting plate 10 and the first end of the clamping arm 6. The clamping arm 6 is easy to rotate, and the clamping arm 6 is more convenient to clamp the shaft sleeve 13 or release the shaft sleeve 13. The first mounting plate 8 and the second mounting plate 10 also play a role in limiting the clamping arm 6.
[0029] In some embodiments, the two ends of the rotating shaft 9 are respectively a first threaded portion and a second threaded portion, the first threaded portion is connected to the first mounting plate 8 through a first nut 4, and the second threaded portion is connected to the second mounting plate 10 through a second nut 11, the first nut 4 is located on the outward side of the first mounting plate 8, and the second nut 11 is located on the outward side of the second mounting plate 10.
[0030] In some embodiments, the hook bodies 61 of the two clamping arms 6 are bent toward the second end of the screw rod 2. The two hook bodies 61 are used to clamp the sleeve 13 from the inside, thereby improving the firmness of the clamping.
[0031] In some embodiments, a threaded sleeve 7 is fixedly connected to one side of the support plate 3, the threaded sleeve 7 has an internal threaded hole, and the screw rod 2 passes through the threaded sleeve 7 and is threadedly matched with the internal threaded hole of the threaded sleeve 7. Extending the length of the threaded connection can prevent the screw rod 2 from deviating during rotation.
[0032] In some embodiments, the second end of the screw 2 is a tapered tip 5 .
[0033] In some embodiments, the longitudinal section of the nut 1 is polygonal, so as to facilitate rotating the nut 1 and the screw rod 2 by a wrench.
[0034] In some embodiments, the length of the screw rod 2 is greater than the length of the clamping arm 6. The length of the screw rod 2 is sufficient to enable the sleeve 13 to be removed from the idler shaft 12.
[0035] In some embodiments, the support plate 3, the clamping arm 6 and the screw rod 2 are all made of stainless steel, which can prevent corrosion and extend the service life of the tool.
[0036] When in use, a tool such as a crowbar is first used to separate the sleeve 13 from the equipment box to create a certain gap, so that the hooks 61 of the two clamping arms 6 can extend into the sleeve 13 and hook the opposite sides of the sleeve 13, and then a wrench is used to rotate the screw rod 2 until the screw rod 2 presses against the idler shaft 12, and the screw rod 2 is continued to rotate to move the sleeve 13 outward from the idler shaft 12, and finally the sleeve 13 is removed. After the sleeve 13 is removed, the bearing 14 can be disassembled.
