Abstract
The utility model relates to the field of bearing boxes of rolling mills, in particular to a bearing box capable of prolonging service life of bearings. The bearing box comprises an upper cover and a base, and is characterized in that at least one through drainage hole is formed in the bottom of the base; the drainage hole is a long circular hole, the length of the hole is 50-55mm, and the width of the hole is 10-12mm. Compared with the prior art, the bearing box has the advantages that after the drainage hole is formed in the bottom of the base of the bearing box and cooling water of a rolling mill enters the bearing box, the water accumulates to the bottom of the bearing box by means of self weight and flows out from the drainage hole, therefore, the water content of bearing grease of the rolling mill is reduced, the further emulsification of the grease is avoided, bearing lubricating efficiency is improved, the service life of the bearings is prolonged, and the consumption costs of spare parts and on-machine accident occurrence rates are further reduced.
Description
Technical field
The utility model relates to the bearing box for rolling mill field, relates in particular to a kind of bearing bearing housing in service life that extends.
Background technology
In hot continuous rolling enterprise, cooling water is indispensable link in rolling mill practice.In the operation of rolling, use cooling water can make roll and steel plate cooling, again template control and the template measurement of rolled plate are played to crucial effect, but cooling water for rolling mill bearing lubricated, be but play counteractive, under the negative pressure that cooling water produces at the milling train High Rotation Speed, from the gap of each assembly parts of bearing housing, enter in bearing housing, with the bearing grease in bearing housing, merge mutually, make lubricating grease emulsification, reduce the lubricating efficiency of bearing, rolling mill bearing can not get lubricated fully, under the effect of high temperature and heavily friction, slowly form spot corrosion, finally peel off, shortened the service life of bearing, incur loss through delay and produce.
Summary of the invention
The purpose of this utility model is to provide a kind of bearing bearing housing in service life that extends, reduce the water content of lubricating grease in bearing housing, prevent the further emulsification of lubricating grease, improve bearing lubrication efficiency, extend bearing service life, reduce the spare parts consumption expense and reduce at the machine accident rate.
For achieving the above object, the technical solution of the utility model is:
A kind of bearing bearing housing in service life that extends, comprise upper cover and base, the minimum osculum that is provided with a perforation in the bottom of described base.Described osculum is slotted hole, hole length 50～55mm, hole width 10～12mm.
Compared with prior art, the beneficial effects of the utility model are: after the bearing block bottom begins to rehearse water hole, after the milling train cooling water enters bearing housing, being pooled to the bearing housing bottom by deadweight flows out from osculum, thereby reduced the water content of rolling mill bearing lubricating grease, prevented the further emulsification of lubricating grease, improved bearing lubrication efficiency, extended bearing service life, and then reduced the spare parts consumption expense and reduced at the machine accident rate.
The accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is the utility model osculum example structure schematic diagram.
In figure: 1-upper cover 2-base 3-osculum
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:
Seeing Fig. 1, is a kind of bearing bearing housing example structure schematic diagram in service life that extends of the utility model, comprises upper cover 1 and base 2, the minimum osculum 3 that is provided with a perforation in the bottom of base 2, and in embodiment, osculum is two.
See Fig. 2, osculum 3 is slotted hole, hole length (l) 50～55mm, hole width (h) 10～12mm all can, in embodiment, hole length is 55mm, hole width is 11mm.
Claims (2)
1. one kind extends the bearing bearing housing in service life, comprises upper cover and base, it is characterized in that the minimum osculum that is provided with a perforation in the bottom of described base.
2. a kind of bearing bearing housing in service life that extends according to claim 1, is characterized in that, described osculum is slotted hole, hole length 50～55mm, hole width 10～12mm.
