Abstract
The utility model discloses an inner streamline structure sealing bearing of a large-size ultralong rolling mill, and relates to the field of bearing manufacturing. The streamline structure sealing bearing comprises a shaft, an outer ring, an inner ring, a sealing ring, a bearing check ring, a sealing assembly and a plurality of columns of rolling bodies, and is characterized in that two columns of rolling paths are arranged on the outer ring of the bearing; four columns of streamline oil storage trenches for storing oil are formed in each of the rolling paths; a plurality of streamline oil storage trenches for storing oil are formed in the surface of the inner ring of the bearing; a plurality of eccentric pressure lubricating oil inlet holes and a plurality of oil return holes are formed in the shaft; a sealing ring slot is formed in the inner circular surface of the check ring on a matched surface of the check ring of the bearing and the shaft; and the sealing ring is embedded into the slot. Inner streamline oil slots for storing lubricating oil are formed in the inner diameter of the inner ring and the rolling paths in the outer ring, so that the lubricating oil can flow into the bearing, and self-lubrication is realized; and furthermore, the nylon sealing ring and the sealing assembly play an effect of preventing impurities from entering the bearing.
Description
Technical field
The utility model relates to bearing and makes the field, relates to concretely streamline sealing structure bearing in a kind of large-scale over-long milling train.
Background technique
The load of metallurgy industry sheet rolling mill is large, and rotating speed is high, often bears large impact continuous duty, and operating mode is more abominable, particularly makees the bearing that support roll is used, and this large size bearing characteristics are multiple row rolling elements, the bearing width overlength, and bearing load is large.In use, disposable installation can not be changed, and can not lubricate the operating mode very severe.The problem of bringing be bearing in running up, the lubricant oil of storage is constantly consumed, in the washing away of cooling liquid, the impurity such as the scale of bringing into, iron filings easily enter into bearing inside, cause the bearing earlier period damage.The steel rolling continuous operation can't often be changed bearing again, and shutdown can cause very large economic loss.So how to solve the working lubrication problem of this large size bearing, be to improve the bearing matter of utmost importance in working life.
Summary of the invention
Defective in view of the prior art existence, the purpose of this utility model is that streamline sealing structure bearing in a kind of large-scale over-long milling train will be provided, this bearing can effectively solve in use lubrication problem of bearing, bearing mainly solves bearing and in use how to avoid entering problem and the design new structure of impurity, so that can constantly obtain lubricating grease at work from the bearing inner flow-line.
For achieving the above object, the technical solution that adopts of the utility model:
Streamline sealing structure bearing in the large-scale over-long milling train, comprise axle, outer ring, inner ring, seal ring, end ring, seal assembly and some row rolling elements, it is characterized in that: described bearing outer ring is provided with two row raceways, respectively is provided with the streamline oil storage ditch of four row trapped fuel on the raceway; Described bearing inner race surface is provided with the streamline oil storage ditch of some trapped fuel; Described axle is provided with pressure lubrication oil oil inlet hole and some spill ports of some Under Asymmetricals; On the fitting surface of end ring and axle, the back-up ring inner headed face is provided with seal groove, and groove is embedded with seal ring.
Described seal ring adopts nylon material.
Working principle of the present utility model: by oil supply system to the lubricant oil certain pressure, make lubricant oil enter bearing inside from the oil inlet hole of axle inside through the streamline oil storage ditch of bearing inner ring, because raceway in the outer ring, bearing inner race are equipped with the interior streamline oil groove that stores lubricant oil.Form the interior lubrication channel of confession lubricant oil by the streamline oil storage ditch on the oil-through hole on the axle, the Internal and external cycle streamline oil storage ditch, so that lubricant oil is not to enter bearing inside from the outside, but carry lubricant oil by streamline oil storage ditch, simultaneously seal ring and seal assembly be when preventing oil leak, can prevent effectively that introduced contaminants from entering bearing internal influence bearing working life.
The utility model has the advantage of: inner ring internal diameter of the present utility model, raceway in the outer ring, be equipped with the interior streamline oil groove that stores lubricant oil, be convenient to lubricant oil and flow into bearing inside, realize selflubricating, sealed nylon circle and seal assembly play the hermetically sealed impurity that prevents and enter the effect of bearing inside simultaneously.
The utility model lubrication state is good, owes lubricated phenomenon without the part, the bearing lubrication self-organizing system, and all-sealed structure effectively stops introduced contaminants to enter, and is pollution-free, is applicable to the working condition that requires the mill speed high loading large, the working life of greatly improving bearing.
