Product Description
The inner slip ring and the outer slip ring on the high-speed wire finishing mill roll box are fixed on the roll shaft and rotate together with the roll shaft, and the waterproof and leakage-proof effects of the roll box are achieved through double-lip sealing clamped between the inner slip ring and the outer slip ring. In addition, when the inner sliding ring is replaced on line, due to the fact that no force application point exists, the inner sliding ring can be taken out well only after the glasses plate is detached, if the glasses plate is not detached, the inner sliding ring can be taken out destructively, damage to a roll shaft is easily caused, operation difficulty is improved, and operation risk is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an inside and outside sliding ring structure of altitude finishing mill roller box can avoid outer sliding ring and interior sliding ring to take place relative rotation at rolling in-process, causes the contact surface wearing and tearing of two sliding rings, and the change of sliding ring in the convenient moreover solves the problem that exists among the background art.
The technical scheme of the utility model is that:
an inner sliding ring and an outer sliding ring structure of a high-speed wire finishing mill roller box comprise an inner sliding ring, an O-shaped sealing ring, a double-lip seal, a roller shaft and an outer sliding ring, wherein the center holes of the inner sliding ring and the outer sliding ring are respectively an inner sliding ring roller shaft mounting hole and an outer sliding ring roller shaft mounting hole which are matched with the roller shaft, and an inner sliding ring O-shaped ring mounting groove and an outer sliding ring O-shaped ring mounting groove which are matched with the O-shaped sealing ring are respectively arranged in the circumferential directions of the inner sliding ring roller shaft mounting hole and the outer sliding ring roller shaft mounting hole; the parts of the inner sliding ring and the outer sliding ring, which are close to the central hole, are thick, the parts of the inner sliding ring and the outer sliding ring, which are far away from the central hole, are thin, the parts of the inner sliding ring, which are close to the central hole, are thick are provided with a jackscrew hole and a positioning groove, the parts of the outer sliding ring, which are close to the central hole, are thick are provided with a positioning block, the positioning block is matched with the positioning groove, and the thin parts of the inner sliding ring and the outer sliding ring, which are far away from the central hole, are respectively an inner.
The positioning block on the thicker part of the outer sliding ring close to the central hole is a rectangular block, and the positioning groove on the thicker part of the inner sliding ring close to the central hole is a rectangular groove matched with the rectangular block.
The inner sliding ring and the outer sliding ring are matched with each other in two positions close to the positioning groove and the positioning block on the thicker part of the central hole.
And four jackscrew holes are uniformly distributed in the circumferential direction on the thicker part of the inner sliding ring close to the central hole.
The inner sliding ring and the outer sliding ring are respectively fixed on the roller shaft, O-shaped sealing rings are respectively arranged between the inner sliding ring and the roller shaft, a positioning block on the thicker part of the outer sliding ring close to the central hole is inserted into a positioning groove on the thicker part of the inner sliding ring close to the central hole, and double-lip sealing is carried out between the thinner parts of the inner sliding ring and the outer sliding ring far away from the central hole.
The utility model has the advantages that: when the inner sliding ring is replaced on line, the inner sliding ring can be taken out from the roll shaft without damage by utilizing the four jackscrews which are uniformly distributed, so that time and labor are saved, and the operation difficulty of replacing the inner sliding ring is reduced; in addition, the inner sliding ring is provided with a positioning groove, the outer sliding ring is provided with a positioning block, the outer sliding ring positioning block is inserted into the inner sliding ring positioning groove, and the positions of the two sliding rings can be fixed, so that the inner sliding ring and the outer sliding ring are prevented from moving relatively, the contact surfaces of the two sliding rings are prevented from being abraded, the service lives of the two sliding rings are prolonged, and the consumption of spare parts is reduced.
