Description

Technical Field

[0001] This utility model relates to the field of steel rolling equipment technology, and in particular to a rigid reinforced bearing housing structure for a short-stress rolling mill. Background Technology

[0002] Short-stress rolling mills are widely used in steel rolling production lines, and their bearing housings are used to install and support the rolls. Commonly, the bearing housings are inserted laterally into the mill frame and then secured with bolts. Under rolling forces, this structure relies primarily on the friction provided by the bolts to resist displacement between the bearing housing and the mill frame, resulting in limited connection rigidity. Under conditions of high rolling forces or impact loads, slight relative displacement or loosening can easily occur, which can affect rolling accuracy and adversely impact equipment lifespan over long-term operation. Therefore, it is necessary to strengthen the existing installation method to improve connection rigidity and stability, while requiring minimal modifications to the original mill frame for ease of implementation. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies that are prone to loosening, and to propose a rigid reinforced bearing housing structure for short-stress rolling mills.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A rigid reinforced bearing housing structure for a short-stress rolling mill includes a bearing housing body with an annular port on one side; The two side ends are integrally formed with the two sides of the bearing housing body; Two insert plates, the surface of the side end of which is provided with a side cavity, the insert plate is slidably disposed in the side cavity, and one end can extend out and be inserted into the corresponding slot of the rolling mill stand; The outer wall of the annular port is sequentially fitted with an axially movable slip ring, a connecting ring, and a threaded ring that is threadedly engaged with the annular port. The connecting ring is rotatably fitted onto the outer wall of the slip ring, and the connecting ring and the threaded ring are fixedly connected. A connecting seat is slidably disposed in the side cavity. One end of the connecting seat is fixedly connected to the slip ring, and the other end is fixed with a guide rod. The insert plate has a side hole, and the top and bottom inner walls of the side hole are provided with oblique guide grooves. The two ends of the guide rod are respectively engaged with the two oblique guide grooves on the same side.

[0005] In one possible design, a fixing seat is also included, which is fixed to the side wall of the rolling mill stand by bolts passing through a waist-shaped hole on its surface. Limiting seats are fixed on both sides of the side end, and a side groove for engaging the limiting seats is provided on the back of the fixing seat.

[0006] In one possible design, an L-shaped seat is fixedly disposed on the surface of the fixing seat, and the lateral section of the L-shaped seat extends to the side of the threaded ring for axial limiting of the threaded ring.

[0007] In one possible design, the annular port has multiple threaded grooves equidistantly spaced along its circumference for connection and fixation to the outer protective shell by bolts.

[0008] In one possible design, the mating surfaces of the limiting seat and the side groove are mutually fitting planes.

[0009] In one possible design, a ball bearing or a lubricating coating is provided between the connecting ring and the slip ring.

[0010] In this application, during actual use, the bearing housing body is inserted into the frame from the side, with the limiting seat fitting against its side wall. Then, by tightening the threaded ring, the connecting ring is rotated and displaced. The connecting ring will drive the slip ring to move axially along the annular port. The slip ring drives the guide rod to move through the connecting seat, and pushes the insert plate outward through the inclined guide groove, thereby inserting the insert plate into the frame and completing the initial installation. Then, bolts are used to install the fixing seat on the side wall of the frame, and the limiting seat is clamped and limited by the side groove, thereby fixing the bearing housing body. At the same time, the transverse section of the L-shaped seat will also clamp and limit the threaded ring to prevent its displacement and further ensure stability.

[0011] In this utility model, the rigid reinforced bearing housing structure of a short stress rolling mill can improve the connection between the bearing housing and the main frame through the integrally formed side end and the telescopic insert plate, thereby enhancing the overall rigidity and load-bearing capacity. In this utility model, the rigid reinforced bearing seat structure for a short-stress rolling mill, through the L-shaped seat, can both clamp the bearing seat and increase its stability, and limit the threaded ring, thereby ensuring the firmness of its connection. In this invention, by adding lateral connections from the inside, the rigidity of the connection between the bearing housing and the frame is improved, thus increasing its stability. Furthermore, the overall modification scope is small, making it convenient to directly modify and upgrade existing rolling mills. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] In one embodiment: Reference Figure 1-3 A bearing housing structure includes: a bearing housing body 1, a side end 2, an insert plate 3, an annular port 4, and a slip ring 11, a connecting ring 12, and a threaded ring 13 that cooperate with it.

[0016] The bearing housing body 1 is an integrally cast structure, with side ends 2 integrally formed on both sides. The surface of the side ends 2 is machined with side cavities 5. The insert plate 3 is slidably disposed inside the side cavity 5, and one end of it can extend outward and be inserted into a pre-set slot in the rolling mill stand. The surface of the insert plate 3 is provided with side holes 6, and the upper and lower inner walls of the side holes 6 are machined with oblique guide grooves 7.

[0017] The annular port 4 is located on the side of the bearing housing body 1, and its outer wall is sequentially fitted with a slip ring 11, a connecting ring 12, and a threaded ring 13. The threaded ring 13 is threaded onto the outer wall of the annular port 4, and the connecting ring 12 is fixedly connected to one side of the threaded ring 13 and rotatably fitted onto the outer wall of the slip ring 11. The slip ring 11 is fixedly connected to one end of the connecting seat 9, and the other end of the connecting seat 9 extends into the side cavity 5 and is fixed with a guide rod 8. The two ends of the guide rod 8 are respectively inserted into two inclined guide grooves 7 on the same side, forming an inclined driving relationship.

[0018] In addition, the fixing seat 14 is installed on the side wall of the rolling mill stand by bolts and waist holes. Limiting seats 17 are provided on both sides of the side end 2, and the back of the fixing seat 14 has a side groove 15 for engaging the limiting seats 17.

[0019] During installation, first push the bearing housing body 1 into the mill stand, so that the limiting seat 17 fits against the side wall of the stand. Rotate the threaded ring 13 to push the connecting ring 12 and the slip ring 11 to move axially, which in turn drives the guide rod 8 to slide in the inclined guide groove 7 through the connecting seat 9, forcing the insert plate 3 to extend outward and insert into the slot of the stand. Then, use bolts to fasten the fixing seat 14 to the side wall of the stand, so that its side groove 15 clamps the limiting seat 17, completing the installation.

[0020] Multiple threaded grooves 10 are equally spaced on the outer periphery of the annular port 4, which can be connected to the protective shell by bolts.
