At the same time, since the silicone sealing ring rotates synchronously with the rotating shaft, wear on the silicone sealing ring is avoided, thereby increasing the service life of the silicone sealing ring.

[0018] (2) In this simple assembled anti-leakage reducer, when the silicone sealing ring ages and leaks oil, the capacitive sensor contacts the oil, which causes a change in the capacitance value and transmits the signal to the signal controller through a wire.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides two technical solutions:

[0027] Figure 1-Figure 5 The first embodiment is shown: a simple assembled anti-leakage reducer, including a gearbox body 1, both ends of the gearbox body 1 are provided with mounting frames 11, the output end of the gearbox body 1 is fixedly installed with a rotating shaft 12, and the left side of the mounting frame 11 is provided with an anti-leakage mechanism 2 for sealing the rotating shaft 12, and the anti-leakage mechanism 2 includes:

[0028] A sealing component 21, which is sleeved on the outside of the rotating shaft 12. The sealing component 21 includes a silicone sealing ring 211 sleeved on the outer wall of the rotating shaft 12. The outer surface of the silicone sealing ring 211 is symmetrically provided with first dynamic sealing copper half rings 213. The two first dynamic sealing copper half rings 213 are movably connected through a plurality of first extrusion springs 215. The bottoms of the two first extrusion springs 215 are both fixedly connected with second dynamic sealing copper half rings 216 through bolts. The two second dynamic sealing copper half rings 216 are movably connected through a plurality of second extrusion springs 218. Static sealing copper rings 219 are movably provided on the back sides of the two first dynamic sealing copper half rings 213 and the second dynamic sealing copper half rings 216.

[0029] The shell component 22 includes a shell 221, and the outer wall of the shell 221 is provided with a heat conducting plate 225, and the outer wall of the heat conducting plate 225 is provided with heat dissipation fins 226. By providing the heat conducting plate 225, the friction heat between the first dynamic sealing copper half ring 213, the second dynamic sealing copper half ring 216 and the static sealing copper ring 219 can be absorbed and released through the heat dissipation fins 226, thereby further improving the service life of the seal.

[0030] A fixing clamp 212 is symmetrically arranged on the outer surface of the silicone sealing ring 211, and the two fixing clamps 212 are fixedly connected by bolts. A first limiting telescopic rod 214 is arranged inside the first extrusion spring 215, and the two ends of the first limiting telescopic rod 214 are fixedly connected to the opposite sides of the two first dynamic sealing copper half rings 213. A second limiting telescopic rod 217 is arranged inside the second extrusion spring 218, and the two ends of the second limiting telescopic rod 217 are fixedly connected to the opposite sides of the two second dynamic sealing copper half rings 216. One of the static sealing copper rings 219 is fixedly connected to the left surface of the mounting frame 11, and the other static sealing copper ring 219 is fixedly connected to the left inner wall of the shell 221.

[0031] When the gearbox body 1 is working, the rotating shaft 12 is driven to drive the silicone sealing ring 211 to rotate, and under the joint action of the first extrusion spring 215 and the second extrusion spring 218, the first dynamic sealing copper half ring 213 and the second dynamic sealing copper half ring 216 on both sides are moved away from each other and squeeze the corresponding static sealing copper ring 219 on both sides. Since the first dynamic sealing copper half ring 213 and the second dynamic sealing copper half ring 216 are in a fit state with the surface of the static sealing copper ring 219, a sealing effect is achieved. At the same time, since the silicone sealing ring 211 rotates synchronously with the rotating shaft 12, wear on the silicone sealing ring 211 is avoided, and the service life of the silicone sealing ring 211 is increased.

[0032] Figure 1-Figure 5 A second embodiment is shown, and its main difference from the first embodiment is that the shell 221 is fixedly mounted on the left surface of the mounting frame 11 by bolts, and a sealing gasket 222 is embedded in the right end of the shell 221, and the right side of the sealing gasket 222 is in contact with the surface of the mounting frame 11. By removing the bolts on the shell 221, the shell 221 can be directly removed from the sealing assembly 21, and the connecting bolts between the first dynamic sealing copper half ring 213 and the second dynamic sealing copper half ring 216 and the connecting bolts between the two fixed clamping rings 212 are removed in turn, so as to facilitate the later replacement of the silicone sealing ring 211, facilitate disassembly and assembly, and improve work efficiency. The left end of the shell 221 is fixedly connected with an anti-overflow box 223, and a capacitive sensor 224 is embedded in the inner wall of the anti-overflow box 223 near the bottom. A signal controller 3 is arranged on the top of the mounting frame 11, and the signal controller 3 is electrically connected to the capacitive sensor 224.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0034] When the gearbox body 1 is working, the rotating shaft 12 is driven to rotate. When the rotating shaft 12 rotates, the silicone sealing ring 211 is driven to rotate. Since the first dynamic sealing copper half ring 213 and the second dynamic sealing copper half ring 216 are installed on the surface of the silicone sealing ring 211 by bolt sleeves, the first dynamic sealing copper half ring 213 and the second dynamic sealing copper half ring 216 rotate, and under the joint action of the first extrusion spring 215 and the second extrusion spring 218, the first dynamic sealing copper half ring 213 and the second dynamic sealing copper half ring 216 on both sides are separated from each other and squeeze the corresponding static sealing copper ring 219 on both sides. Since the first dynamic sealing copper half ring 213 and the second dynamic sealing copper half ring 216 are in a state of contact with the surface of the static sealing copper ring 219, a sealing effect is achieved. At the same time, since the silicone sealing ring 211 rotates synchronously with the rotating shaft 12, wear on the silicone sealing ring 211 is avoided, and the service life of the silicone sealing ring 211 is increased.

[0035] When the silicone sealing ring 211 ages and leaks oil, the oil seeps from the gap between the right static sealing copper ring 219 and the rotating shaft 12 to the gap of the middle silicone sealing ring 211, and seeps into the inside of the anti-overflow box 223 through the gap between the left static sealing copper ring 219 and the rotating shaft 12. At this time, when the capacitive sensor 224 contacts the oil, it will cause a change in the capacitance value and transmit the signal to the signal controller 3 through the wire. The signal controller 3 then feeds back the signal to the terminal device to remind the staff to deal with it in time.

[0036] By providing the heat conducting plate 225 , the friction heat between the first dynamic sealing copper half ring 213 , the second dynamic sealing copper half ring 216 and the static sealing copper ring 219 can be absorbed and released through the heat dissipation fins 226 , thereby further improving the service life of the seal.
