Definitions
- the invention relates to a reel for winding
- Metal strip in particular of rolled hot strip, with a mandrel shaft having a first shaft end, which is rotatably supported by means of at least one bearing provided in the reel frame.
- a rolling stand or rolling mill consisting of several rolling stands.
- a coil To wrap the metal band into a coil, called a coil, is at the output of the
- Rolling device provided a reel.
- a reel has a drive shaft driven by a drive shaft.
- the mandrel shaft is usually rotatably supported by several bearings in the machine frame of the reel. On the protruding from the machine frame operator end of the mandrel shaft is the
- a hot strip reel mandrel may have a mass of more than 10 tons, which requires a correspondingly large hoist with high investment costs. The shunting of the hoist in the area of the reel is cumbersome because the space is often very tight.
- the clamping device can be designed differently. According to their type of actuation, they can be actuated both mechanically and hydraulically. In a preferred embodiment it is provided that the clamping device is designed as a hydraulically operated clamping sleeve. It has a preferred construction for receiving a hydraulic medium provided
- Cavity in the form of a hollow cylinder If this cavity is subjected to hydraulic pressure, there is a radial expansion of the clamping sleeve and as a result thereof in the region of the bearing seat to a radial spread. This frictional connection can be solved again by reducing the hydraulic pressure and the elastic
- the clamping takes place by means of a mechanical clamping sleeve.
- the clamping force is generated manually
- Figure 1 is a schematic representation of the
- Figure 2 shows a first embodiment of the invention, in which the clamping device is designed as a hydraulic clamping sleeve;
- Figure 3 shows a second embodiment of the invention, in which the tensioning device is a combination of hydraulic tensioning device and mechanical tensioning device is formed;
- FIG 4 shows another variant of the invention, in which the
- Clamping device as shown in the upper partial section, from a combination consisting of a hydraulic shaft nut and a mechanical clamping sleeve, or - as shown in the lower section section - is designed as a mechanical shaft nut clamping device.
- FIG. 1 shows parts of a reel 1 in a greatly simplified representation.
- the reel 1 has a mandrel shaft 2.
- the mandrel shaft 2 is rotatably supported in a drive-side part 18 by means of two bearings 4 in a machine frame 3. These two bearings 4 can, for example
- Rolling be each having an inner ring and a
- Machine frame 3 protrudes in Figure 1 to the left side, includes a spreading device for winding the hot strip to a collar 6.
- a support bearing 19 supports the outer left end of the spike shaft second
- the mandrel shaft 2 is driven by a non-illustrated drive via the drive piece 16, which by means of a coupling, for example a 1ösbaren, positive locking Connection, for example in the form of a
- interlocking connection can also be designed differently, for example, an intermeshing wedge-shaft wedge hub profile. The required for the winding process
- Torque is thus transmitted essentially through this coupling.
- connection between the mandrel shaft 2 and the inner ring of the respective bearing 4 is a detachable
- the tensioning device 5 is constructed such that in a tensioned state, a mandrel shaft 2 introduced into the bearing 4 can be fixed by frictional engagement. For this purpose, a radial expansion in the region of the bearing seat is generated by the tensioning device 5 until it is ensured that there is no slippage between the spine shaft 2 and the inner ring of the bearing 4. By relaxing the tensioning device 5, the frictional connection between the bearing 4 and mandrel shaft 2 can be easily solved again, so that the mandrel shaft 2 from the
- Machine frame 3 in the direction of arrow 10 of the
- FIG. 2 shows an embodiment in which a hydraulic clamping sleeve 17 is arranged on the drive-side end piece 18. On the outer circumference, the hydraulic clamping sleeve 17 is surrounded by a bushing 11 with a collar, which in turn is enclosed by the inner ring of the bearing 4. The bearing 4 sits on the outer peripheral side on a bearing half shell 14. The two end faces of the bearing 4 are protected by a bearing cover 13 and a seal, not shown.
- a cavity 12 is provided in the clamping sleeve 17. This cavity has the shape of a hollow cylinder. It extends axially across the width of the bearing 4.
- the cavity 12 is connected to a channel which leads to the outside and is closed by a closure 15. This makes it possible to introduce a hydraulic fluid with pressure, so that the opposite in the cavity 12 ring parts of the clamping sleeve 17 undergo a radial expansion. This can be done for example by connecting a pressure line in conjunction with a hydraulic pump. The pressure in the cavity causes the annular parts of the clamping sleeve 12, which face one another in the hollow space, to move slightly away from one another and produce a radially directed pressure between the shaft end piece 18 and the bearing 4, which defines the spiked shaft 2 in the bearing 4. When this connection is to be released, the hydraulic pressure in the cavity 12 is reduced.
- FIG. 3 shows an embodiment in which the
- Clamping device 5 is also designed as a hydraulic clamping sleeve 17, but this directly, that is without
- FIG. 4 shows, in the upper and lower partial sections, an embodiment in each case in which the frictional engagement is produced by a conical seat with a tapered bushing. At the top
- Machine frame 3 can be fixed, or can be removed by releasing the frictional connection of the machine frame 3.
- a significant advantage of the invention is that by means of the clamping device quickly and easily mounted a spike shaft 2 in a machine frame 3 of a reel 1
