In order to solve the technical problem, the utility model discloses a following technical scheme:
a sealing device for a end cover of a roller crusher comprises a spacer ring, wherein the spacer ring is fixedly arranged on a rotating shaft through a flat key, one end of the spacer ring penetrates through a box body, and a gap is formed between the spacer ring and the box body; an end cover is arranged outside the spacer ring, a dustproof ring is arranged between the end cover and the spacer ring, the end cover is fixed on the box body through a bolt, and an elastic gasket is arranged between the end cover and the box body.
Preferably, the end face of the end cover is provided with a through hole, a rotating shaft penetrates through the through hole, and a gap is formed between the rotating shaft and the end cover.
Preferably, the dust ring is mounted on the spacer ring and is in direct contact with the inner wall of the end cover; an annular groove is arranged at the contact position of the inner wall of the end cover and the dust ring.
Preferably, the dust ring is made of a carbon-carbon composite material.
The utility model discloses owing to adopted above-mentioned technical scheme, following beneficial effect has: the device adopts a contact type assembly technology, achieves the sealing effect by utilizing the structure of the dustproof ring, has the characteristics of high temperature resistance, good friction performance and the like in the working process, can reduce the friction of the device, and can also reduce the material consumption; in operation, the device is easy to install and maintain.
Drawings
The accompanying drawings are included to provide a preferred understanding of the present invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention and not to limit the invention. In the drawings:
fig. 1 is a schematic view of the overall structure of the present invention.
Reference numbers in the figures: the dust-proof device comprises a rotating shaft 101, a box body 102, a key 103, a spacer ring 104, a dust ring 105, an end cover 106 and an elastic gasket 107.
Detailed Description
The following describes preferred embodiments of the present invention in detail with reference to the accompanying drawings.
As shown in the figures, the end cover sealing device of the roller crusher comprises a spacer ring 104, wherein the spacer ring 104 is fixedly arranged on a rotating shaft 101 through a flat key 103, one end of the spacer ring 104 penetrates through a box body 102 to protect the rotating shaft, and a gap is arranged between the spacer ring 104 and the box body 102 to reduce friction; an end cover 106 is arranged outside the spacer ring 104, a dust ring 105 is arranged between the end cover 106 and the spacer ring 104, the end cover 106 is fixed on the box body 102 through bolts, and an elastic gasket 107 is arranged between the end cover 106 and the box body 102, so that the sealing performance of the device is improved.
The end face of the end cover 106 is provided with a through hole, the rotating shaft 101 penetrates through the through hole, and a gap is formed between the rotating shaft 101 and the end cover 106 to prevent friction between the rotating shaft and the end cover 106.
The dust ring 105 is mounted on the spacer ring 104 and is in direct contact with the inner wall of the end cover 106; the annular groove is formed in the contact position of the inner wall of the end cover 106 and the dust ring 105, the sealing performance of the device can be improved by the annular groove, and the defect that the sealing effect is poor due to the fact that the dust ring 105 and the end cover 106 are rubbed can be overcome.
