Description

Technical Field

[0001] This utility model belongs to the field of rolling mill technology, and in particular relates to a bearing seat mounting structure for a shaft support bracket. Background Technology

[0002] Rolling mills are essential equipment in the steel production process. The ends of the rolls are mounted to bearing housings via bearings. The bearing housings are movably connected to the shaft support bracket along the height direction. Because the shaft support bracket and bearing housing experience impact and friction during roll operation, a liner is added between the bearing housing and the mounting hole. Currently, the liner is detachably installed at the corresponding position on the shaft support bracket and bearing housing. This installation structure has several problems: First, the liner will wear down after prolonged use, affecting the accuracy of the roll's installation position. Since the liner is installed inside the strip-shaped mounting hole, replacing the liner requires completely disassembling the bearing housing, leading to low maintenance efficiency. Second, during rolling, iron filings can enter the gap between the liner and the mounting hole of the shaft support bracket, scratching the liner and shortening its service life.

[0043] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] like Figures 1 to 9As shown, a bearing housing mounting structure for a shaft support bracket includes: a shaft support bracket, wherein the mounting plate 1 of the shaft support bracket has a strip-shaped mounting hole 103; a bearing housing 2, wherein the bearing housing 2 has mounting bosses 201 at both ends, the mounting bosses 201 being located inside the strip-shaped mounting holes 103 of the two mounting plates 1; a U-shaped liner plate 5, wherein the vertical plate 501 of the U-shaped liner plate 5 is located on both sides of the mounting bosses 201, and the U-shaped liner plate 5 is detachably connected to the mounting bosses 201; and an L-shaped liner plate 4, wherein the horizontal plate of the L-shaped liner plate 4 is detachably connected to the bearing housing 2, and the vertical plate of the L-shaped liner plate 4 is located between the bearing housing 2 and the vertical plate 501.

[0045] The thickness of the mounting boss 201 is less than the thickness of the bearing seat 2; there is a gap between the vertical plate 501 of the U-shaped liner 5 and the side wall of the strip mounting hole 103; a first through hole is opened on the bottom plate of the U-shaped liner 5; a first connecting bolt 502 passes through the first through hole and is threaded to the inside of the first threaded hole on the mounting boss 201; a second through hole is opened on the horizontal plate of the L-shaped liner 4; a second connecting bolt 401 passes through the second through hole and is threaded to the inside of the second threaded hole of the bearing seat 2; there is a gap between the vertical plate of the L-shaped liner 4 and the mounting plate 1.

[0046] Compared to the traditional method of installing a liner plate inside the strip mounting hole 103, the U-shaped liner plate 5 and L-shaped liner plate 4 facilitate replacement and improve the maintenance efficiency of the equipment.

[0047] The edge of the vertical plate 501 of the U-shaped liner 5, away from the bottom plate and the mounting boss 201, has a chamfered structure. The vertical plate of the L-shaped liner 4 has a chamfered structure that matches the chamfered structure of the vertical plate 501. The chamfered structure of the vertical plate fits snugly with the chamfered structure of the vertical plate 501. During the installation of the U-shaped liner 5 and the L-shaped liner 4, the chamfered structure of the vertical plate and the chamfered structure of the vertical plate 501 are tightly pressed together, which helps to prevent the vertical plate and the vertical plate 501 from deforming.

[0048] The mounting boss 201 is equipped with a corresponding scraping component, which is a scraper 3. The scraper 3 is located inside the strip-shaped mounting hole 103, and the width of the scraper 3 matches the width of the strip-shaped mounting hole 103. The scraper 3 is used to clean the inner wall of the strip-shaped mounting hole 103 to prevent iron filings and other debris from scratching the U-shaped liner 5. The scraper 3 has a third through hole 301, and a third connecting bolt 303 passes through the third through hole 301 and is threaded into the inner side of the third threaded hole of the bearing seat 2. The scraper 3 is a structural component made of polytetrafluoroethylene (PTFE), which improves its service life. A first cleaning boss 302 is fixed at one end of the scraper 3, and the first cleaning boss 302 is in contact with the end face of the mounting plate 1 near the bearing seat 2. The first cleaning boss 302 cleans the part of the mounting plate 1 corresponding to the L-shaped liner 4 to prevent iron filings and other debris from scratching the L-shaped liner 4.

[0049] In other embodiments, the mounting boss 201 is provided with a corresponding scraping assembly, which includes two scraper blocks 6. Each scraper block 6 has a guide hole 603. A guide shaft 7 is located inside the guide hole 603, and a compression spring 701 is located outside the guide shaft 7. The compression spring 701 is positioned between the two scraper blocks 6, and the two scraper blocks 6 are respectively in contact with the inner end face of the strip-shaped mounting hole 103. Under the elastic force of the compression spring 701, the two scraper blocks 6 are pressed tightly against the vertical side of the strip-shaped mounting hole 103. A strip plate 602 is fixed to the lower end of each scraper block 6, forming a strip-shaped hole between the strip plates 602 of the two scraper blocks 6. A fourth connecting bolt 604 passes through the strip-shaped hole and is threaded into the inner side of the third threaded hole of the bearing seat 2. The fourth connecting bolt 604 limits the movement of the scraper blocks 6, and there is a gap between the head of the fourth connecting bolt 604 and the strip plate 602 to prevent the scraper blocks 6 from detaching from the bearing seat 2. Two second cleaning protrusions 601 are fixed on the end face of the scraper block 6 away from the other scraper block 6. The distance between the two second cleaning protrusions 601 matches the thickness of the mounting plate 1. The mounting plate 1 is located between the two second cleaning protrusions 601, and the two second cleaning protrusions 601 are respectively attached to the two sides of the mounting plate 1. During the up and down movement of the bearing seat 2, the scraper block 6 is used to clean the inner wall of the strip-shaped mounting hole 103 to prevent iron filings from scratching the U-shaped liner 5. The second cleaning protrusions 601 clean the parts of the mounting plate 1 and the L-shaped liner 4 respectively to prevent iron filings from scratching the L-shaped liner 4, thereby improving the service life of the U-shaped liner 5 and the L-shaped liner 4. The scraper block 6 is a structural component made of polytetrafluoroethylene (PTFE). When the scraper block 6 wears, under the elastic force of the compression spring 701, the scraper block 6 is pressed against the side wall of the strip-shaped mounting hole 103 to extend the service life of the scraper block 6. The PTFE scraper block 6 has good wear resistance, which extends the service life of the scraper block 6.

[0050] The mounting bracket includes two mounting plates 1. The lower end of the mounting plate 1 is fixedly connected to the base 104, and the upper end of the mounting plate 1 is fixedly connected to the top plate 105. A mounting seat 101 is fixedly provided at the lower end of the mounting plate 1, and the mounting seat 101 is connected to the base 104 by mounting bolts. The top plate 105 is connected to the mounting plate 1 by mounting bolts. A vertical reinforcing rib 102 is provided between the mounting seat 101 and the mounting plate 1, which improves the structural strength of the mounting plate 1.

[0051] When the liners need to be replaced, loosen the first connecting bolt 502 and the second connecting bolt 401 to quickly replace the U-shaped liner 5 and the L-shaped liner, which improves the maintenance efficiency of the rolling mill.
