Abstract
The utility model relates to a connecting mode of a roller with a bearing end cover. One end of the roller is supported and fixed through a bearing. An end part of the roller is provided with a plurality of threaded holes. The bearing end cover is connected to the roller through studs. A first threaded end of each of the studs is connected with each of the threaded holes of the roller. A second threaded end of each of the studs is screwed on the bearing end cover through a nut. According to the utility model, the bearing end cover is connected to the roller through the studs, installation and disassembly are convenient, defects that screw connection is unreliable and the roller is easy to be damaged after frequent disassembly in the prior art are avoided, a service life of the roller is prolonged, and production efficiency is raised.
Description
Technical field
The utility model relates to rolling mill, especially the connected mode of roll and bearing (ball) cover.
Background technology
Roll is the strength member on steel rolling mill's rolling mill; The pressure that produces when utilizing a pair of or one group of roll rolling rolls the stone roller steel; Roll is the strength member that directly contacts and make metal generation plastic deformation in the rolling mill with rolled piece, also is expendable parts, in use; Need often to change, perhaps adjust roll location.
In the prior art, as shown in Figure 1, the two ends of roll 102 are through bearing 101 support fixation usually, and said roll 102 ends have a plurality of screwed holes, pass bearing (ball) cover 103 through screw 104 and are fixed on the roll 102.In the actual use, when needs adjusting roll 102 positions, when perhaps changing roll 102; Need to shut down, with changing roll 102 then after the bearing arrangement dismounting, often knockout screw 104 can cause 105 on roll to hold screwed hole being worn; When once more roll 102 being installed, bearing (ball) cover 103 and roll 102 to be connected meeting unreliable, not only increased the use cost of parts; Roll is short service life, has also reduced the production efficiency of whole rolling mill.
The utility model content
The applicant can damage the roll screwed hole to frequent knockout screw in the above-mentioned prior art; Shortcoming such as roll service life is low; The connected mode of roll and bearing (ball) cover a kind of rational in infrastructure, easy for installation is provided, thereby installation and removal are convenient; Improve the service life of roll, improved production efficiency.
The technical scheme that the utility model adopted is following:
The connected mode of a kind of roll and bearing (ball) cover; One end of roll is fixed through bearings; The end of said roll has a plurality of screwed holes; Bearing (ball) cover is connected on the roll through studs, and first end of thread of said studs is connected with screwed hole that roll leaves, and second end of thread of said studs is tightened on the bearing (ball) cover through nut.
Its further technical scheme is:
One end of said studs is provided with the homalocephalus structure;
First end of thread of said studs becomes interference fits with screwed hole that roll leaves.
The beneficial effect of the utility model is following:
The utility model is through studs connection bearing end cap and roll, and installation and removal are convenient, and it is unreliable to have avoided using screw to connect in the prior art, often dismantles the defective of fragile roll screwed hole, has prolonged the service life of roll, enhances productivity.
Description of drawings
Fig. 1 is the sketch map that is connected of roll and bearing (ball) cover in the prior art.
Fig. 2 is the structural representation of the utility model.
Fig. 3 is the structural representation of the utility model studs.
Fig. 4 is the right view of Fig. 3.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described.
As shown in Figure 2; The connected mode of described roll of the utility model and bearing (ball) cover; The two ends of roll 102 are through bearing 101 support fixation, and the end of roll 102 has four screwed holes, and bearing (ball) cover 103 is connected on the roll 102 through studs 4; 102 on first end of thread 401 and the roll of studs 4 are opened screwed hole and are connected, and become interference fits; Second end of thread 402 of studs 4 is tightened on the bearing (ball) cover 103 through nut 5.See Fig. 3 and Fig. 4, an end of studs 4 is provided with homalocephalus structure 403, when being convenient to installation and removal, and the clamping of clamping tool.
In the actual use; During installation: earlier bearing 101 is fixed on the roll 102; First end of thread 401 of studs 4 screwed in 102 on roll open in the screwed hole; Cover bearing (ball) cover 103 then, on second end of thread 402 of studs 4, screw on pad and nut 5, it is fastenedly connected; During dismounting: unclamp nut 5 and pad, dismounting bearing 101 backs are changed roll 102 and are got final product.Promptly realized the installation and removal of roll easily, it is fastening firm to install, convenient disassembly, and during dismounting, studs 4 is still stayed in the roll 102, has protected 102 on roll to open screwed hole, and is not easy to wear, prolonged the service life of roll, improved production efficiency.
More than describing is the explanation to the utility model, is not the qualification to utility model, and the utility model institute restricted portion within the protection domain of the utility model, can be done any type of modification referring to claim.
