Description

Technical Field

[0001] This utility model relates to the field of roller press technology, specifically to a roller press bearing housing with axial adjustment function. Background Technology

[0002] Currently, roller presses are widely used in the cement, metallurgy, and mining industries as a high-efficiency and energy-saving grinding equipment. Roller presses are composed of units such as shaft system, main frame and feeding device. The bearings of roller presses are located on the guide rail plate of the lower crossbeam. The bearing seat of the fixed roller moves horizontally back and forth in the inner cavity of the main frame by the guidance of the guide rail plate.

[0003] The rollers in the existing roller press include movable rollers and fixed rollers. The movable rollers squeeze the material against the fixed rollers. Under high pressure, strong stress is generated inside the material particles, causing them to crack and pulverize. When the movable roller squeezes the material, due to the unevenness of the material and the lack of axial support for the bearing seat, the axial displacement of the bearing seat of the movable roller is easy to occur, making the equipment unstable. Summary of the Invention

[0004] The purpose of this invention is to provide a roller press bearing housing with axial adjustment function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a roller press bearing housing with axial adjustment function, comprising a bearing housing and two guide rail plates fixed on the roller press frame, side friction reducing plates installed on both the top and bottom sides of the bearing housing, and end friction reducing plates installed on both the top and bottom sides of the bearing housing, the end friction reducing plates being in contact with the guide rail plates, the guide rail plates being slidably connected to the side friction reducing plates and the end friction reducing plates, and a bearing being installed in the inner hole of the bearing housing.

[0006] Preferably, an adjusting shim is installed between the side friction reducing plate and the bearing seat, and the thickness of the adjusting shim is 1mm-2mm.

[0007] Preferably, the bearing housing has grooves at both the top and bottom, and the end friction-reducing plate is installed in the groove.

[0008] Preferably, the bearing housing has steps on both the top and bottom sides, and the side wear-reducing plates are installed on the steps.

[0009] Preferably, the side friction reducing plate has an "L" shaped cross section, and the side friction reducing plate and adjusting shims are bolted to the top and bottom sides of the bearing seat.

[0010] Preferably, the end friction-reducing plate is made of polytetrafluoroethylene material and is attached to the top and bottom grooves of the bearing seat with AB glue. The end friction-reducing plate is designed with oil grooves.

[0011] Preferably, the guide rail plate is fixed to the roller press frame by bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By adjusting the number and thickness of the adjusting shims installed between the side friction reducing plate and the bearing housing, the relative position of the guide rail plate and the bearing housing can be adjusted. Since the guide rail plate is fixed, the axial position of the bearing housing can be adjusted, making the equipment operation more stable. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a roller press bearing seat with axial adjustment function, including a bearing seat 1 and two guide rail plates 5 fixed on the roller press frame. Side friction reducing plates 2 are installed on the top and bottom sides of the bearing seat 1, and end friction reducing plates 4 are installed on the top and bottom sides of the bearing seat 1. The end friction reducing plates 4 are in contact with the guide rail plates 5, and the guide rail plates 5 are slidably connected to the side friction reducing plates 2 and the end friction reducing plates 4. A bearing 6 is installed in the inner hole of the bearing seat 1.

[0023] In this utility model, an adjusting shim 3 is installed between the side grinding plate 2 and the bearing seat 1. The thickness of the adjusting shim 3 is 1mm-2mm. The adjusting shim 3 has two thicknesses, 1mm and 2mm. The number of shims of each thickness can be adjusted as needed.

[0024] In this utility model, the bearing housing 1 has grooves at the top and bottom, and the end wear-reducing plate 4 is installed in the grooves.

[0025] In this utility model, the bearing housing 1 has steps on both the top and bottom sides, and the side wear-reducing plate 2 is installed on the steps.

[0026] In this utility model, see Figure 4 The side grinding plate 2 has an "L" shaped cross section. The distance from the side grinding plate 2 to the center of the bearing seat 1 can be adjusted by adjusting the number and thickness of the adjusting shims 3. The side grinding plate 2 and the adjusting shims 3 are installed on the top and bottom sides of the bearing seat 1 by bolts.

[0027] In this utility model, see Figure 5-6 The end friction reducing plate 4 is made of polytetrafluoroethylene material and is attached to the top and bottom grooves of the bearing housing 1 with AB glue. This can prevent the end friction reducing plate 4 from sliding with the bearing housing 1 and facilitate the replacement of the end friction reducing plate 4 after wear. The end friction reducing plate 4 is designed with oil grooves 7 to ensure that the grease can lubricate evenly.

[0028] In this utility model, the guide rail plate 5 is fixed to the roller press frame by bolts, and there is sliding friction between the guide rail plate 5, the side friction reducing plate 2, and the end friction reducing plate 4.

[0029] The working principle of this utility model is as follows: By adjusting the number and thickness of the adjusting shims 3 installed between the side friction reducing plate 2 and the bearing seat 1, the relative position of the guide rail plate 5 and the bearing seat 1 can be adjusted. Since the guide rail plate 5 is in a fixed state, the axial position of the bearing seat can be adjusted, making the equipment operation more stable.
