Abstract
The utility model discloses a bearing seat device conductive to avoiding abrasion of a rolling mill stand. The bearing seat device comprises a bearing seat support (21), an embedded lining plate (22), a roller (23), a bearing seat (24) and a fastening bolt (25). The embedded lining plate (22) is half embedded into the bearing seat support (21) in a sleeved mode and fastened. The roller (23) penetrates through the embedded lining plate (22) to be connected with the bearing seat (24), and the bearing seat (24) is fastened to the embedded lining plate (22) through a fastening bolt (25). According to the bearing seat device conductive to avoiding abrasion of the rolling mill stand, the structure that the embedded lining plate and the bearing seat are matched is used, the on-line rolling tonnage of a rolling mill is guaranteed, the occurrence rate of deformation problems caused when the stand is repaired is lowered, the time of maintaining work is reduced, and the service life of the rolling mill stand is prolonged. The bearing seat device conductive to avoiding abrasion of the rolling mill stand is simple in structure, safe and quick, reliable in working, and convenient to mount.
Description
Technical field
The utility model belongs to smelting iron and steel technical field, further belongs to rolling technical field, be specifically related to a kind of simple in structure, safe and efficient, reliable operation, the bearing holder device that helps avoid rolling-mill housing wearing and tearing.
Background technology
Milling train is nipped moment at steel, roll causes larger impact by bearing block to framework memorial archway, make window side inside rolling-mill housing memorial archway, framework memorial archway bottom surface etc. all occur corrosive wear in various degree, make rolling-mill housing and roll chock gap be difficult to effective control and management, often occur that rolling-mill housing and roll chock gap surpass the phenomenon of management limiting value.Mill housing gap increases the condition of work that has worsened mill main drive system, makes main transmission vibratory impulse large, when steel ingot is nipped, easily skids, and has influence on the control of plate shape, and product quality is made a big impact.
Milling train is unstable simultaneously, has shortened the normal on-line rolling tonnage of milling train.For reducing frame and bearing block gap, improve milling train stability, frame is carried out to built-up welding reparation; In repair process, frame deforms because being heated, and finally scraps.For this reason, research and develop a kind of simple in structure, safe and efficient, reliable operation, the easy for installation bearing holder device that helps avoid rolling-mill housing wearing and tearing, is with a wide range of applications.
Utility model content
It is a kind of simple in structure, safe and efficient that the purpose of this utility model is to provide, reliable operation, the easy for installation bearing holder device that helps avoid rolling-mill housing wearing and tearing.
The purpose of this utility model is achieved in that and comprises bearing block support, embedding liner plate, roll, bearing block and fastening bolt; Described embedding liner plate is partly nested in bearing block and supports interior and fastening; Described roll is connected with bearing block through embedding liner plate, and described bearing block is anchored on embedding liner plate by fastening bolt.
The utility model adopts embedding liner plate and bearing block fit structure, has guaranteed the on-line rolling tonnage of milling train, has reduced the incidence that causes problem on deformation when frame is repaired, and has reduced the time of upkeep operation, the service life of having improved frame.The utility model is simple in structure, safe and efficient, and reliable operation is easy for installation.After improvement, frame and the way of contact of metal (upper seat will directly contact and change panelling into and contact with bearing block, and panelling is copper part, and itself can not be worn bearing block and frame, after panelling wearing and tearing, can directly change, and frame itself abrasion condition can not occur.The gap of milling train between operation of rolling mid frame and bearing block is comparatively stable, has improved frame service life, and frame is without reparation, and the distortion of having avoided frame built-up welding reparation to cause, can save production cost 20000 yuan every year.
Accompanying drawing explanation
Fig. 1 is that the utility model duty master looks schematic diagram;
Fig. 2 is the right side cross section view of Fig. 1;
In figure: 1-mill housing, 2-bearing holder device, 21-bearing block supports, 22-embedding liner plate, 23-roll, 24-bearing block, 25-fastening bolt.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but never in any form the utility model is limited, and any conversion or the improvement based on the utility model training centre, done, all fall into protection domain of the present utility model.
As shown in Figure 1 and 2, the utility model comprises bearing block support, embedding liner plate, roll, bearing block and fastening bolt; Described embedding liner plate is partly nested in bearing block and supports interior and fastening; Described roll is connected with bearing block through embedding liner plate, and described bearing block is anchored on embedding liner plate by fastening bolt.
The degree of depth of described embedding liner plate 22 embedded axle bearings supports 21 and the Thickness Ratio of embedding liner plate 22 are 1:1 ~ 4.
Via diameter on described embedding liner plate 22 is greater than roll 23 through 1 ~ 3mm of shaft diameter.
The lower end of described embedding liner plate 22 is close to bearing block and is supported 21.
The thickness of described embedding liner plate 22 is for being greater than 12 ~ 20mm.
When described embedding liner plate 22 appearance and sizes are square, adopt fastening bolt mode and bearing block to support 21 fastening.
When described embedding liner plate 22 appearance and sizes are circular, adopt engage thread and bearing block to support 21 fastening.
Described embedding liner plate 22 and bearing block support the mode of 21 employing interference fits.
operation principle of the present utility model and the course of work:
The utility model adopts embedding liner plate and bearing block fit structure, and embedding liner plate is partly nested in bearing block and supports interior and fastening; Roll is connected with bearing block through embedding liner plate, and bearing block is anchored on embedding liner plate by fastening bolt.
During maintenance replacing, dismounting step, then departs from bearing block support by the dismounting of embedding liner plate or rotation; The embedding liner plate of again need being changed is fastened on bearing block and supports above, and fit on bearing block, completes the replacing of consumable accessory.
