回転全受止めると共に、導管と通路の間の連結を行う。In the above-mentioned roll, in order to heat or cool the use surface of the roll to a temperature different from the environmental temperature, or to maintain the roll surface temperature at the environmental temperature when the roll surface temperature changes to that extent, a fluid heat medium such as hot water, Steam, oil, and salt solutions are pumped into the roll passages. The passage inside the roll consists of holes formed in the roll in the longitudinal direction, conduits arranged in a spiral shape inside the roll,
Alternatively, it can be configured as a relatively thin-walled cylinder consisting of a barrel-like displacement body disposed within the roll at a short distance from the inner surface of the roll.The internal passage of the roll rotates but is connected to the roll. The supply pipe and the discharge pipe are stationary. A rotating connection head is attached to one roll to form a connection without relative movement;
It absorbs all rotation and provides a connection between the conduit and the passageway.

ンによって接続ストツノ平に対して密閉される。In known rotary connection heads of this type, a connecting tube aligned with the end face of one of the rolls is fixed, and a connecting body that surrounds this connecting tube and connects the supply tube and the discharge tube is a carbon bearing. It is supported on the connecting pipe through the packing ring or No.J? It is sealed against the connecting strut flat by a ball-shaped axial packing with a packing box.
この公知例は長時間にわたって、種々異なる使用温度が
かけられる場合又は始動と停止の場合、十分な密封を行
なえないという困難に常に直面する。炭素軸受上の支承
と球欠状軸方向パツキンは余り精密でなく、やがて洩れ
を伴なう摩耗を生じる傾向があるからである。This prior art always faces the difficulty of not being able to provide an adequate seal over long periods of time, when subjected to different operating temperatures, or during start-up and shut-down. This is because the bearings and ball-shaped axial packings on carbon bearings are not very precise and tend to wear out over time with leakage.
この発明の目的は、ロールと軸方向に連結することがで
きる接続管を設け、固定接続体が上記接続管の上に密接

。The object of the invention is to provide a connecting pipe which can be connected axially to the roll, a fixed connecting body being closely supported on said connecting tube, a supply pipe and a discharge pipe being connected to said connecting body,
A permanent rotary connecting head for supplying and discharging a heating or cooling fluid medium to a heating or cooling roll, in which a flow connection is formed from a supply pipe through a flow channel in the roll to a discharge pipe. The goal is to improve it so that you can get better results.

ン社耐久性が犬であり、その上、トルクを僅かしか消費
しない利点がある。[Means, actions, and effects for solving the problem] In order to achieve this objective, the cram school connector is supported on the connecting pipe via two radial bearings spaced apart in the axial direction, and a slip-ring packing is provided between this connecting tube and the connecting body O. Two axially spaced radial bearings ensure a precise bearing of the connecting body on the connecting tube. This bearing is independent of the wear state of the grip and is known for fluid motion machines.
Slip ring suitable for temperatures exceeding 0℃・41
Makes it possible to use Tsukin. A suitable slip ring, made of a material suitable for sliding and surrounding the connecting tube, is pressed against the radial sliding surface and closely rests against this surface. This kind of durability is outstanding, and it has the advantage of consuming very little torque.
しかし、このノクッキンについても、間隔が比較的大き

チー・母リングを有する円錐クランプ継手を介して接続
管をロールに固定する。However, even with this nookin, if the spacing is relatively large, the tightening of the slip ring or the slip ring surface will of course require inspection or replacement of the ring. In the prior art, it is necessary to remove the connecting tube from the end side of the roll in order to access the interior of the rotary connecting head. For this purpose, in a known example, the connecting tube is fastened to the roll via a conical clamp joint with a split tee and a base ring.
これに対して、ロールから接続管を取り外さずに密封部
材に゛近付くことができるように、回転接続ヘッドを改
良するという一歩進んだ目的が出て来る。On the other hand, a further objective arises to improve the rotary connecting head in such a way that the sealing member can be accessed without removing the connecting tube from the roll.

すことができる。By allowing the connecting head to be pulled out of the connecting tube along the radial bearing opposite the roll,
This advanced objective is achieved. In this way (of course with the locking fully released), the connecting body can be removed from the connecting tube on the opposite side of the roll without removing the connecting tube.
またこのような構造上の改良は接続管とロールとの確実
な結合管可能にする。それは密閉が簡単なことで、円錐
クランプ継手に勝るという利点がある。Such structural improvements also allow for a reliable connection between the connecting tube and the roll. It has an advantage over conical clamp fittings in that it is easy to seal.

ことは、金属ベローズが担当するようにすることが好ま
しい。The strip ring seal consists of a slizzo ring installed between the radial bearing and the retaining part of the connecting pipe, and a tightening ring in contact with the slizzo ring, which seals the strip ring along the radial bearing and the retaining part of the connecting pipe. Preferably, a metal bellows is responsible for applying the pressure.
しかも、金属ベローズは比較的大きな温度範囲にわたっ
て弾件的性質を維持し、ゾラスチ、クベローズと違って

0℃以上の温度でも損傷を被らない利点がある。Furthermore, metal bellows maintains its elastic properties over a relatively large temperature range and, unlike Zolast and Kuberose, do not become brittle at low temperatures and do not cause 25% embrittlement during roll heating.
It has the advantage of not being damaged even at temperatures above 0°C.

This is done in a slip ring joint generally designated by reference numeral 5. The slip link 5 includes a slip ring 6 provided between the radial bearing 4 and a retaining part or shoulder formed on the outer periphery of the connecting pipe 1, and a tightening ring that interacts with the slip ring 6. 7, the clamping ring 7 is held by a metal bellows 8 and pressed against the sealing surface 22 of the slip ring 6. On the other hand, the metal bellows 8 is pressed against the annular flange 9 and is connected to the connecting body 2 via this. 5. When trying to fully heat the roll. Slip ring・

When it is engaged with the outer circumferential groove of the radial bearing 4 and tightened, it presses the inner ring of the radial bearing 4, as is clear from the first factor. Stop segment 1
0, remove the coupling screw 23 that connects the two connecting members 2' and 2'' constituting the main body of the connecting body °2 that are adjacent in the axial direction, and then attach the screw to the connecting body 21 on the left side in Figure 1. It can be pulled out from the connecting pipe 1 (that is, on the side facing away from the roll, not shown).

A conduit 13 coaxial with the connecting body 2 passes through it, and in the embodiment shown in FIG. In this way, the conduit 13 is fixed inside the five-turn connecting flank. This conduit 13 is used as an outgoing or returning path for communicating with a passage system provided within the cylindrical body. A turret body fixed in a roll with a closed outer circumference (Verdr
aengungakoerper) maintains a spacing between the inner periphery of the roll configured as a hollow body, such that the heating or cooling medium passes through the spacing between the displacement body and the inner periphery of the hollow roll. For this purpose, a fixed conduit 13 is particularly considered.

There, the heating or cooling medium is transferred to the curved pipe 15 in the direction of arrow A.
through conduit 13. After passing through the passage in the roll, the heating or cooling medium returns in the direction of the arrow ) through the gap between the inner circumference of the connecting tube 1 and the outer circumference of the conduit 13 and then enters the connecting tube 17 . For example, a discharge pipe 3o is connected to the connection pipe 17.

The conduit 13' is therefore also separated from the flange-like cover 14'. The heating or cooling medium sent through the supply pipe 20f is thus supplied to the flange cover 14'.
Since the bath enters the compartment 18 between the pipe 13' and the pipe 13', an auxiliary gasket 19 must be provided there. The auxiliary A-coating 19 prevents the heating or cooling medium from entering and simultaneously reaching the compartment 21 which is connected to the discharge pipe 30 .
