Description

Technical Field

[0001] This utility model belongs to the field of roller gap adjustment technology, specifically relating to a novel roller gap adjustment device with torque. Background Technology

[0002] The cone box, as a crucial piece of equipment for transmitting power to the roll box, boasts extremely high reliability. Its key components include driving gears, drive shafts, driven shafts, bevel gears, rolling bearings, sliding bearings, and adjusting mechanisms. A complete rolling mill also requires a roll box mounted on the cone box for reducing the diameter of the wire rod. The roll box contains a roll gap adjustment device with an adjusting gear at each end. The cone box also has an adjusting mechanism for roll gap adjustment, with a gear on the adjusting mechanism meshing with the gear on the roll box. After the roll box is installed in the cone box, the two gears engage with a clearance of approximately 0.3 mm. During operation, power is transmitted to the gears of the roll gap adjustment device by rotating the adjusting mechanism on the cone box, thus adjusting the roll gap size.

[0003] Currently, because the roll gap adjustment mechanism on the cone box lacks forward and reverse locking and torque adjustment functions, the roll gap adjustment device on the roll box is prone to widening under rolling force, resulting in unqualified rolling dimensions. In severe cases, it may cause steel piling up in downstream rolling mills due to unqualified incoming material dimensions, and in extreme cases, it may even cause the roll box to burn out.

The novel torque-driven roller gap adjustment device provided by this invention has the characteristic of being able to adjust the magnitude of the torque, thereby achieving forward and reverse locking functions, so that the roller gap remains unchanged after adjustment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a novel torque-driven roller gap adjustment device, comprising a shaft and a bearing housing, wherein a bearing is installed inside the bearing housing, the shaft is connected to the inner ring of the bearing, a pressure cap is connected to one side of the bearing housing, a spacer corresponding to the pressure cap is connected to the shaft, and a friction plate assembly for providing torque is connected to the pressure cap and the spacer.

[0006] In order to generate friction and thus provide torque, the friction plate assembly further includes an internal tooth friction plate and an external tooth friction plate, wherein the internal tooth friction plate and the external tooth friction plate are alternately arranged, the internal tooth friction plate is connected to the spacer, and the external tooth friction plate is connected to the gland.

[0007] To adjust the torque, a butterfly-shaped washer located at the end of the friction plate assembly is further fitted on the spacer, and a lock nut located on the side of the butterfly washer is threaded onto the spacer.

[0008] To accurately adjust the roller gap size by matching the actual scale to the design values ​​of the roller box, a disc with a scale is mounted on the shaft. A mounting base is also included, on which a pointer is mounted, and the pointer has an indicator groove corresponding to the scale.

[0009] To clamp the dial and achieve double locking of the roller gap, an anti-loosening seat is further included. The anti-loosening seat includes a seat body and an anti-loosening plate. The seat body is installed on the pressure cover, and the anti-loosening plate is connected to the seat body by bolts. The anti-loosening plate and the seat body are located on both sides of the disc, respectively.

[0010] To further buffer the axial impact force, a buffer gasket is provided between the bearing housing and the gland.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model drives the spacer to rotate by rotating the shaft, which in turn drives the inner tooth friction plate to rotate. The rotation of the inner tooth friction plate and the outer tooth friction plate generate friction, thereby providing torque and realizing the locking function after the roll gap is adjusted, ensuring the stability after the roll gap is adjusted.

[0013] 2. The spacer of this utility model is fitted with a butterfly-shaped washer located at the end of the friction plate assembly, and the spacer is threaded with an anti-loosening nut located on the side of the butterfly-shaped washer.

[0024] Example 1

[0025] Please see Figures 1-3 This embodiment provides the following technical solution: A novel torque-driven roller gap adjustment device includes a shaft 1 and a bearing housing 3. A bearing 2 is installed inside the bearing housing 3. The shaft 1 is connected to the inner ring of the bearing 2. A pressure cap 5 is connected to one side of the bearing housing 3. A spacer 10 corresponding to the pressure cap 5 is connected to the shaft 1. Friction plate groups 9 for providing torque are connected to the pressure cap 5 and the spacer 10. The friction plate group 9 includes an internal tooth friction plate 91 and an external tooth friction plate 92, wherein the internal tooth friction plate 91 and the external tooth friction plate 92 are alternately arranged. The internal tooth friction plate 91 is connected to the spacer 10, and the external tooth friction plate 92 is connected to the pressure cap 5.

[0026] By adopting the above technical solution, the present invention drives the spacer 10 to rotate through the rotation of shaft 1, thereby driving the internal tooth friction plate 91 to rotate. The rotation of the internal tooth friction plate 91 and the external tooth friction plate 92 form friction force, thereby providing torque, realizing the locking function after the roll gap is adjusted, and ensuring the stability after the roll gap is adjusted.

[0027] Specifically, a butterfly gasket 11 located at the end of the friction plate assembly 9 is fitted on the spacer 10, and an anti-loosening nut 12 located on the side of the butterfly gasket 11 is threaded onto the spacer 10.

[0028] By adopting the above technical solution, the clamping force of the butterfly washer 11 on the friction plate group 9 can be changed by adjusting the position of the anti-loosening nut 12, thereby adjusting the magnitude of the torque.

[0029] Specifically, a buffer pad 4 is provided between the bearing housing 3 and the pressure cap 5.

[0030] The above technical solution is used to buffer axial impact force.

[0031] Example 2

[0032] The difference between this embodiment and embodiment 1 is that, specifically, a disc 6 is mounted on the shaft 1, and a scale 7 is mounted on the disc 6. It also includes a mounting base 13, on which a pointer 14 is mounted, and the pointer 14 has an indicator groove 15 corresponding to the scale 7.

[0033] By adopting the above technical solution and setting the dial 7, the actual scale can be matched according to the design value of the roller box, thereby allowing for precise adjustment of the roller gap size.

[0034] Example 3

[0035] The difference between this embodiment and embodiment 1 is that: specifically, it also includes an anti-loosening seat 8, which includes a seat body 81 and an anti-loosening plate 82. The seat body 8 is installed on the pressure cover 5, and the anti-loosening plate 82 is connected to the seat body 81 by bolts. The anti-loosening plate 82 and the seat body 81 are located on both sides of the disc 6 respectively.

[0036] By adopting the above technical solution, the scale 7 can be clamped by setting the anti-loosening seat 8, thus achieving double locking of the roller gap.

[0037] In summary, this invention uses the rotation of shaft 1 to drive the rotation of spacer 10, which in turn drives the rotation of internal tooth friction plate 91. The rotation of internal tooth friction plate 91 creates friction with external tooth friction plate 92, providing torque and achieving a locking function after roll gap adjustment, ensuring stability. A butterfly-shaped washer 11 is fitted onto spacer 10 at the end of friction plate assembly 9, and a locking nut 12 is threaded onto spacer 10 located on the side of butterfly washer 11. By adjusting the position of locking nut 12, the clamping force of butterfly washer 11 on friction plate assembly 9 can be changed, thereby adjusting the torque. A buffer washer 4 is provided between bearing seat 3 and pressure cap 5 to buffer axial impact force. The dial 7 allows for precise adjustment of the roll gap size by matching the actual scale with the design values ​​of the roll box.
