Description of the invention [Technical field to which the invention belongs] The present invention relates to a rolling mill, and in particular to an improved roller assembly with a so-called cantilever type, in which a cone sleeve is tightly embedded It fits between the annular roller and the tapered surface section of the shaft, so that the annular roller with a cylindrical hole is concentric with the tapered surface section of the shaft. [Prior Art] As described in U.S. Patent No. 5,934,131, in the conventional roller assembly of the above type, the tapered sleeve is forced into its effective engagement position by a rigid circular retainer. The retainer is rotatably fixed to the shaft, and the retainer can be further advanced against the sleeve by applying a button force to a nut provided at the end of the shaft. Therefore, the screw of the retainer is pressed against the outer abdomen of the roller, and the inner abdomen of the roller is pressed against the shoulder of the shaft. When tightened, this screw becomes the primary means of transmitting torque from the roller shaft to the roller. What are the disadvantages of this mechanism. First, the tapered sleeve may not fit into its effective position until the retainer screw is tightened against the outer belly of the roller, so the roller and roller shaft are not properly concentric. Second, the outer belly of the roller may be damaged by the force transmitted by the retainer screws. The object of the present invention is to provide a roller combination that overcomes these disadvantages. SUMMARY OF THE INVENTION The roller assembly of a rolling mill according to the present invention includes a support shaft having a tapered surface section extending from a base section to an end section. An endless roller with -4- (2) (2) 200405829 an inner abdomen, an outer abdomen, and a cylindrical hole. The roller with the inner abdomen located against the seat and the cylindrical hole surrounding the shaft. The manner of the tapered surface section is arranged axially on the shaft. A tapered sleeve 'is inserted between the tapered section of the shaft and the cylindrical hole of the roller. A bearing ring 'is rotatably fixed to and axially moves on the end section of the shaft outside the roller. An elastic element is disposed between the bearing ring and the sleeve to deformably maintain an initial gap between the bearing ring and the outer abdomen of the roller. A roller holder is arranged on the end section of the shaft outside the bearing ring. The roller holder acts in abutting relation with the load ring, and gradually and at least partially closes the gap between the roller and the load ring by the elastic element, and gradually and accurately forces the sleeve into its fitting position. A bolt member is threaded through the roller holder, wherein the torsion force applied by the bolt member to the bearing ring against the outer belly of the roller is sequentially applied to the outer belly of the roller against the seat. These and other features, advantages, and objectives will be described in more detail with reference to the drawings. [Embodiment] Referring first to the first and third to fifth figures, the _wheel combination of the present invention is numbered 10, and the roller combination includes a support shaft 12 having a tapered section 14 from a pair of fingers 1 8 a 1 b formed by 1 8 b extends to one end section 20. Bolt grooves are formed at 22 outer portions of the end section 20 and threads are formed at 24 outer portions. An annular roller 26 has an inner abdomen 28, an outer abdomen 30, and a cylindrical hole 34. The annular roller 26 is axially assembled on the support shaft 12, and the inner belly portion 28 abuts the seat portion 16, and the cylindrical hole 34 surrounds the -5- (3) 200405829 cone surface segment 14 of the support shaft. -The tapered sleeve 36 is inserted between the tapered surface section 14 of the support shaft and the roller cylindrical hole 34, and the inner end of the sleeve is formed with an outer bolt groove 22 that mechanically engages the support shaft end section 20 at 38. A load-bearing ring 40 is sleeved on the support shaft end section 20, and the section 20 can slide axially. By interlocking the inner bolt groove 42 with the outer bolt groove 22 in conjunction therewith, the bearing ring 40 is rotatably fixed to the support shaft. The ring 48 holds a spring holder 46 in position, and holds a plate 44 in an inner cavity of the bearing ring 40. A roller holder 50 is screwed on the end section 20 of the roller shaft. A bolt 52 is screwed through the hole containing the thrust button 54. The roller combination is set step by step as described in the figure below. In FIG. 2A, the roller 26 is assembled on the end surface 20 of the shaft in such a manner that the inner belly portion 28 contacts the seat portion 16 and the circle ΐ is wound around the conical section 14 of the shaft. The barrel 36 is inserted into the circle of the roller without radial interference. Tube hole 34 and section 14. Fig. 2B. The bearing ring 40 engages the outer bolt groove 22 with its inner bolt groove 42 on the end section 20 of the shaft. The spring-shaped retainer 46 is used to cause the dish-shaped spring sleeve 36 to engage the outer end 'of the sleeve 36 to deformably maintain a gap 5 6 on the outer belly of the bearing ring 40 and the roller. The bolt slot of the wheel 26 is to support the shaft at the end by a buckle spring and a removable screw 5 hole 34 ring. Taper surface of tapered sleeve shaft Assembled spring 44 assembly 30-6-(4) 200405829 Figure 2 C Roller holder 50 is screwed on the end section 20 of the shaft, and torsion is applied to compress the dish The spring 44 is sufficient to partially close the gap 56, and the elastic resultant force is sufficient to generate an interference fit between the tapered sleeve 36, the cylindrical hole 34 of the roller, and the tapered surface section 14 of the shaft. Therefore, the roller at this time is precisely concentric with the shaft.
第2D圖 施扭力於可卸螺栓52，以迫使承載環40抵住輥輪26 外腹部30，此亦導致內腹部28緊抵座部1 6。Figure 2D. Torque is applied to the detachable bolt 52 to force the bearing ring 40 against the outer abdomen 30 of the roller 26, which also causes the inner abdomen 28 to abut against the seat portion 16.
綜上所述，可瞭解在施扭力於可卸螺栓5 2之前，錐 形套筒36係穩固地位於且干涉配合於滾輪的圓筒孔34和 軸的錐面段1 4間，此可確保輥輪和輥輪軸之同心且軸向 對齊。施扭力於可卸螺栓，然後藉由軸向地夾持於輥輪於 軸的座部和承載環之間，且後者與軸的外腹部環狀接觸， 而完成組裝。扭力從輥輪的軸可靠地傳輸至輥輪，而不會 造成輥輪的損害。 【圖式簡單說明】 第一圖顯示本發明輥軋機的輥輪組合之一直立剖面視 圖； 第二A至二C圖顯示第一圖所示輥輪組合之連續組 合步驟的剖面視圖； 第三圖顯示設於錐形套筒和承載環間的彈性元件之透 -7- (5) (5)200405829 視圖；及 第四和五圖顯示分別沿第一圖之4-4和5-5線所取之 水平剖面視圖。 主要元件對照表 10 輥輪組合 12 支撐軸 14 錐面段 16 座部 1 8 a指部 1 8 b指部 20 端段 22 栓槽 2 4 螺紋 26 環形輥輪 28 內腹部 30 外腹部 3 2 外槽 3 4 圓筒孔 36 錐形套筒 3 8 栓槽 40 承載環 4 2 內栓槽 44 碟形彈簧 -8 - (6) (6)200405829 46 彈簧保持器 4 8 扣環 50 輥輪保持器 52 可卸螺栓 54 止推鈕 56 間隙In summary, it can be understood that before the torque is applied to the removable bolt 52, the tapered sleeve 36 is firmly located and interferes with the cylindrical hole 34 of the roller and the tapered surface section 14 of the shaft, which can ensure that The rollers and roller shafts are concentric and axially aligned. Torque is applied to the removable bolt, and then the assembly is completed by axially clamping the roller between the seat of the shaft and the bearing ring, and the latter is in annular contact with the outer abdomen of the shaft. Torque is reliably transmitted from the roller shaft to the roller without causing damage to the roller.
