Description
Technical field
It the utility model is related to a kind of bearing (ball) cover protective device, and in particular to a kind of ground roll end cap protection device.
Background technology
Steel billet is mainly transported using ground roll in steel-making continuous casting region, ground roll mainly by ground roll shaft, bearing block, bearing,
End cap, sprocket wheel etc. form.Gear reducer drives ground roll to rotate by chain, sprocket wheel, and ground roll reaches transport steel by the rotation of itself
The purpose of base.Ground roll is carried out every time finding during offline reparation ground roll shaft, bearing block, the component such as sprocket wheel can Reusability, bearing,
Wear of end cover is serious.The service life of bearing and end cap directly affects the service life of a whole set of ground roll.
Ground roll is because use environment temperature is high and the reasons such as lubricating system cannot be effectively ensured cause bearing easy to wear.Bearing damages
It is not easy to be noticeable after bad, even if finding bearing damage, because the reasons such as produced on-site can not be in time replacing ground roll, axis
Ground roll can only carry out downward eccentric rotary and causes wear of end cover serious due to gravity after holding damage.Every time during reparation ground roll only
The end cap of abrasion can all be replaced, cause largely to waste.
Utility model content
In view of this, the purpose of the utility model is to overcome the deficiency of above-mentioned prior art, there is provided a kind of ground roll end cap
Protective device, it is by setting a protective case in the inside of bearing (ball) cover, according to the guarantor that the dimensioned of bearing (ball) cover is supporting
Sheath is embedded in end cap endoporus and is positioned, and can effectively repair the end cap of abrasion, recover its sealing function.
To solve above technical problem, technical solutions of the utility model provide a kind of protective device of ground roll end cap, including
Bearing (ball) cover 1 and protective case 2, wherein, the bearing (ball) cover 1 has an endoporus 3, and protective case 2 is installed on the endoporus of bearing (ball) cover 1
In 3.
Further, the outside diameter of the protective case 2 is consistent with the internal diameter of the endoporus 3 of bearing (ball) cover 1.
Further, the protective case 2 is tubular structure.
Further, the end of the protective case 2 is equipped with positioning step 4, and protective case 2 is installed on the endoporus 3 of bearing (ball) cover 1
Afterwards, positioning step 4 and bearing (ball) cover 1 are connected with each other by spot welding.
Further, the point is welded in the afterbody of positioning step 4.
In another technical solution of the utility model, further, the end of the protective case 2 is equipped with positioning step 4,
After protective case 2 is installed on the endoporus 3 of bearing (ball) cover 1, positioning step 4 and bearing (ball) cover 1 are connected with each other by bolt 5.
Further, the positioning step 4 is equipped with through hole, and is equipped with through hole in the correspondence position of bearing (ball) cover 1, protects
After sheath 2 is installed on the endoporus 3 of bearing (ball) cover 1, bolt 5 passes through positioning step through hole and bearing (ball) cover through hole, by positioning step
4 are connected with each other with bearing (ball) cover 1.
Further, the screw rod of the bolt 5 is made of the polished rod portion of nearly bolt head and the threaded portion of distal end.
Further, there is internal thread inside the bearing (ball) cover through hole, the bolt 5 passes through positioning step through hole and axis
Socket end lid through hole, is connected by threaded portion with bearing (ball) cover through hole internal thread.
Further, oil filler point 6 is set on the bearing (ball) cover 1.
End cap main function is that the bearing in bearing block is positioned and sealed, and the abrasion of end cap is concentrated mainly on endoporus
Wear, no longer possess sealing function after wear of end cover.Therefore the utility model installs a protective case in the inner side of bearing (ball) cover, protects
Sheath ends locating and machining step, is fixed at bearing (ball) cover with positioning step after the completion of being assembled with bearing (ball) cover, prevents
Wear-resistant sleeve comes off with bearing (ball) cover.End cap after restructuring only need to be with changing protective case after wearing every time, and end cap body part can
Reusability, has greatly saved rehabilitation cost.To solve the problems, such as that it is big that bearing lubricates difficulty in use, also in end cap
Upper processing oil filler point, can be oily to the bearing progress in bearing block at any time, extends the service life of bearing, overall lifting ground
The service life of roller.
It can be seen from the above technical proposal that the utility model has the advantages that：
1st, the utility model is without integrally replacing bearing, it is only necessary to one protection of installation in the inner side of bearing (ball) cover
Set, end cap every time after abrasion only need to changing protective case, bearing (ball) cover body part can Reusability, greatly saved and repaiied
Multiple cost.
2nd, protective case end locating and machining step, after the completion of being assembled with bearing (ball) cover at bearing (ball) cover and positioning step into
Row is fixed, and prevents wear-resistant sleeve from coming off with bearing (ball) cover.
