In modern steel rolling technology, CA heat treatment (heat treatment of promptly annealing) is an important ring in the steel band heat treatment technology, and the conveying of the roller-way of steel band makes that rhythm of production is more compact, operation is more simple, can significantly boost productivity.Simultaneously higher productivity has also proposed more and more higher requirement to infrastructure device, and employed in the industry at present furnace roller bearing with spherical outside surface is to adopt centralized fuel feeding lubricated, but there is following shortcoming in bearing with spherical outside surface lubricated:

1.. the requirement of oil product and open type oil leak waste cause lubricated cost height (the CA1-6 line uses more than 1500 altogether to bearing with spherical outside surface).

2.. the lubricant oil of leakage pollutes cooling water.Contain certain toxicity and radioactivity in the lubricant oil, " energy-saving and emission-reduction " aspect input strengthens.

3.. because higher oily temperature causes lubricating pipe to stop up and be dry and hard, make bearing with spherical outside surface locking under unlubricated state, shortened the working life of bearing with spherical outside surface; The frequent furnace roller of changing has had a strong impact on the continuity of producing.

4.. after long-time the use, because of relative displacement very easily takes place in wearing and tearing, the tank filler sleeve of original oiling aperture off-axis bearing makes drier oil can not enter bearing inside on the bearing between bearing and bearing support, and reveal away the gap between bearing and bearing support, cause and can not lubricate and waste.

For this reason, furnace roller bearing with spherical outside surface lubricating system is set about developing, improving to reduce oil product and consumption and prolongation bearing with spherical outside surface working life.

At present, also not having a direct solution to this problem is domestic, all is the service behaviour that as far as possible improves lubrication system generally, automatically with manually suppress the working method that combines, ensure the normal lubricated of each roller-way bearing, but fundamentally do not solve the lubricated difficult problem of bearing with spherical outside surface.

Summary of the invention

In order to overcome above-mentioned existing disadvantages of background technology part, the utility model provides a kind of outer spherical surface store oil bearing support.

The purpose of this utility model reaches by following measure: outer spherical surface store oil bearing support, it comprises base support, be positioned at the bolt hole on the base support, bearing on the fixed base support, it is characterized in that on the described bearing tank filler sleeve being arranged, tank filler sleeve is communicated with the oiling ring of annular, and an end of described bearing has the store oil closed chamber, described store oil closed chamber has seal ring by being bolted on the bearing between store oil closed chamber and bearing.

In technique scheme, the oiling ring on the described bearing has 2 to 5 oil grooves to be communicated with the store oil closed chamber.
