Description
Technical Field
The utility model belongs to the technical field of belt conveyors, and particularly relates to a novel carrier roller sealing structure.
Background
The roller is one of the essential parts of the belt conveyor, and plays a role in supporting a belt and bearing materials, so that the stable operation of the conveyor belt is ensured. With the development of belt conveyors and market demands, the bandwidth is larger and the traffic is increasing. The diameter of the used carrier roller also needs to be correspondingly increased, and the traditional sleeve sealing structure cannot achieve the sealing effect along with the increase of the roller diameter of the carrier roller.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a novel carrier roller sealing structure, which improves the sealing effect on a carrier roller and prolongs the service life of the carrier roller.
The utility model is realized by the following technical scheme: a novel carrier roller sealing structure comprises a roller body and a shaft, wherein the roller body is sleeved on the shaft through a bearing, an inner sealing ring sleeved between the roller body and the shaft is installed at one end, facing the inner side of the roller body, of the bearing, an inner labyrinth seal and a waterproof outer labyrinth seal are sequentially arranged at one end, facing the outer side of the roller body, of the bearing from inside to outside, the inner labyrinth seal is clamped in the roller body, and the outer labyrinth seal is clamped on the circumferential surface of the shaft; the outer side of the outer seal of the waterproof labyrinth is provided with a dust cover which is clamped between the roller body and the shaft, and the shaft positioned at the outer side of the dust cover is provided with an axial check ring for axially limiting the dust cover.
Furthermore, an annular cover cap with a Z-shaped section is arranged between the outer seal of the waterproof labyrinth and the dust cover, and one end of the annular cover cap is clamped between the roller body and the inner seal of the labyrinth.
Further, the annular cover is made of hot-rolled steel plate.
Further, the manufacturing material of the dust cover is high-density polyethylene.
The utility model has the beneficial effects that: the utility model provides a novel seal structure has improved the sealed effect to the bearing roller, extension bearing roller life, and protection conveyer operation improves conveyer work efficiency, reduces the later maintenance cost.

Detailed Description
The utility model is further illustrated below with reference to the figures and examples.
As shown in fig. 1 and 2, the novel carrier roller sealing structure comprises a roller body 7 and a shaft 8, wherein the roller body 7 is sleeved on the shaft 8 through a bearing 5. The bearing 5 is installed towards the inboard one end of roll body 7 and is adorned the inner seal ring 6 of suit between roll body 7 and axle 8, and the both sides of inner seal ring 6 are carried out axial spacing by bearing 5 and the inboard shaft shoulder of roll body 7 respectively, and bearing 5 keeps away from the one end of inner seal ring 6 is carried out axial spacing by the retaining ring for the shaft. One end of the bearing 5 facing the outer side of the roller body 7 is provided with an inner labyrinth seal 4 and an outer waterproof labyrinth seal 3 from inside to outside in sequence, the inner labyrinth seal 4 is clamped in the roller body 7, and the outer waterproof labyrinth seal 3 is clamped on the circumferential surface of the shaft 8; the outer side of the waterproof labyrinth outer seal 3 is provided with a dust cover 1, the dust cover 1 is clamped between the roller body 7 and the shaft 8, and the shaft 8 positioned on the outer side of the dust cover 1 is provided with an axial retainer ring 9 for axially limiting the dust cover 1. Preferably, in this embodiment, an annular cover 2 with a Z-shaped cross section is further disposed between the waterproof labyrinth outer seal 3 and the dust cover 1, and one end of the annular cover 2 is clamped between the roller body 7 and the labyrinth inner seal 4.
The dust cover 1 and the annular cover 2 are used for playing a dustproof role, the dust cover 1 is made of high-density polyethylene, and the annular cover 2 is made of hot-rolled steel plates, so that the dust cover 1 and the annular cover 2 have longer service life. The arrangement of the waterproof labyrinth outer seal 3 and the labyrinth inner seal 4 prevents outside water from entering the roller body and prevents lubricating grease from overflowing. The inner sealing ring 6 mainly prevents that lubricating grease from overflowing to the inside of the roller body and reducing lubrication, and reduces the service life of the carrier roller.
