Description

Technical Field

[0001] The utility model relates to the technical field of bearing equipment, and more specifically, to a bearing gland mechanism for work roll installation. Background Art

[0002] The lower work roll of the existing leveler is installed by combining a lower roll bearing seat and a lower roll bearing cover, etc. The lower roll bearing cover, the inserted blind cover, and the inserted through cover fix the bearing in the lower roll bearing seat. The work roll and the bearing rotate during the working process. The lower roll bearing cover is an integral structure made of cast steel. Since the work roll is the main load-bearing component of the leveler, the bearing and the bearing cover are prone to damage during use. When replacing, the entire lower roll bearing cover needs to be removed, the bearing and the work roll are taken out, the entire lower roll bearing cover and the bearing are replaced, and after replacing with a new bearing, the entire lower roll bearing cover is installed again and the accuracy is readjusted.

[0003] Since the bearing gland needs to be fixed by a plurality of bolts or screws, the disassembly and replacement process of such a bearing gland mechanism is cumbersome and complex. Summary of the Invention

[0004] The purpose of the utility model is to provide a bearing gland mechanism for work roll installation.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows: a bearing gland mechanism for work roll installation, including two roll seats and a plurality of roll shafts. End shafts with an integral structure are provided at both ends of the roll shaft. A groove for accommodating the end shaft is opened at the upper part of the roll seat. A bearing is sleeved on the surface of the end shaft, and the bearing is engaged with the corresponding groove. A semi-circular gland is provided above the bearing. Integral rib plates are provided at both ends of the semi-circular gland. The length of the rib plate is half of the length of the semi-circular gland. The rib plate is fixedly connected to the roll seat by bolts. A baffle is fixedly installed at the inner side position of the groove at the upper part of the roll seat. A card slot is opened on one side of the baffle close to the semi-circular gland. A limit rib inserted into the card slot is fixedly provided at one end of the semi-circular gland.

[0006] Preferably, the rib plates at both ends of the semi-circular gland are arranged in an alternating manner.

[0007] Preferably, inner gland covers and outer gland covers are sleeved at both ends of the bearing respectively.

[0008] Preferably, annular grooves are opened at both ends of the bottom of the groove, and annular ribs inserted into the annular grooves are fixedly provided outside the inner gland cover and the outer gland cover.

[0009] Preferably, the arc of the semi-circular gland matches the arc of the bearing.

[0010] Compared with the prior art, the advantages of the utility model are as follows:

[0011] The utility model reduces the contact area between the semi-circular cover and the roller seat, thereby reducing the usage amount of bolts or screws, making the maintenance operation convenient, reducing the cost input of replacement parts. At the same time, the semi-circular cover can be clamped with the upper baffle of the roller seat through the limiting rib, which can make up for the problem of unstable structure caused by reducing bolts or screws.

[0018] The following will elaborate on the preferred embodiments of the present utility model in conjunction with the drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0019] Refer to Figure 1 、 Figure 2 and Figure 3As shown in the figure, the present utility model provides a bearing gland mechanism for the installation of working rolls, which includes two roll seats 1 and multiple roll shafts 2. The two ends of the roll shaft 2 are provided with integral end shafts 21. A groove 11 for accommodating the end shaft 21 is formed in the upper part of the roll seat 1. A bearing 3 is sleeved on the surface of the end shaft 21, and the bearing 3 is engaged with the groove 11 at the corresponding position. A semi-circular gland 6 is arranged above the bearing 3. Integral rib plates 61 are arranged at both ends of the semi-circular gland 6. The length of the rib plate 61 is half of the length of the semi-circular gland 6. The rib plate 61 is fixedly connected with the roll seat 1 by bolts. A baffle 12 is fixedly installed at the inner side position of the groove 11 on the upper part of the roll seat 1. A clamping groove 121 is formed on one side of the baffle 12 close to the semi-circular gland 6. A limiting rib 62 inserted into the clamping groove 121 is fixedly arranged at one end of the semi-circular gland 6. The limiting rib 62 can further limit the vibration of the semi-circular gland 6, thereby effectively reducing the loosening of the fixing bolts and improving the stability.

[0020] Further, to ensure that the semi-circular glands 6 of adjacent roll shafts 2 can be installed side by side and reduce the space occupation, in this embodiment, the rib plates 61 at both ends of the semi-circular gland 6 are arranged in a staggered manner.

[0021] To prevent dust and impurities from entering the bearing 3, in this embodiment, inner gland covers 4 and outer gland covers 5 are respectively sleeved at both ends of the bearing 3.

[0022] To further increase the stability of the inner gland cover 4 and the outer gland cover 5, in this embodiment, annular grooves are formed at both ends of the bottom of the groove 11, and annular ribs inserted into the annular grooves are fixedly arranged on the outer parts of the inner gland cover 4 and the outer gland cover 5.

[0023] In this embodiment, the radian of the semi-circular gland 6 matches the radian of the bearing 3.

[0024] The specific operation steps are as follows: When the bearing 3 needs to be replaced, loosen the bolts fixing the semi-circular gland 6, take out the semi-circular gland 6, use the sling of the lifting equipment to lift the roll shaft 2, lift out the roll shaft 2, the inner gland cover 4 and the outer gland cover 5 together, and then remove the bearing 3 from the end shaft 21, and then the bearing 3 can be replaced.

[0025] Although the embodiments of the present utility model are described in conjunction with the accompanying drawings, the patent owner can make various deformations or modifications within the scope of the appended claims. As long as it does not exceed the protection scope described in the claims of the present utility model, it should be within the protection scope of the present utility model.
