Abstract
The utility model discloses a rolling mill bearing with an oil seal, comprising an outer ring, an inner ring, a cylinder roller, a protection frame, a steel clasp; also comprising an oil seal, which is pressed on an inner diameter of two side ribs of the outer ring, the inner diameter is provided with locating ports for locating the oil seals of a rotary shaft, and the main lip and auxiliary lip of the inner diameter of the rotary shaft oil seal form a seal pair together with a raceway of the bearing inner ring. The steel clasp is made of spring steel, is a circular ring and is provided with opening; the middle portion of the inner ring is provided with circular clamping groove; and the steel clasp is arranged in the circular clamping groove. The seal structure of the utility model ensureslubrication and improves effectively wearing lifetime of the bearing, the bearing consumption is reduced obviously in a rolling process, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of roller-mill bearing, particularly relates to a kind of roller-mill bearing that has oil sealing.
Prior art
All contain inner ring, outer ring, four row rollers, retainer four parts in the structure of roller-mill bearing, the outer back-up ring in addition that has.Bearing inner race does not have rib, and it is fastened on the roller neck, can come with the overall separation of bearing, with the bearing exchange of other same model, so that roll change.But because the working environment of roller-mill bearing is very abominable, not only high temperature, high load, the erosion that also will bear a large amount of cooling waters, hammer scale and dust.And milling train needs often to change roll at work, in order to make roll change quick, easy, the bearing support seal arrangement that makes is all fairly simple, its sealing effect is not good, and lubricating grease is run off, and water and iron filings, dust are invaded bearing inside, roller-mill bearing does not reach the fatigue life of expectation, the raceway face layer takes place too early to be peeled off, even " stuck " phenomenon that usually bearing takes place, heavy losses brought to steel rolling production.
Summary of the invention
In view of this, it is lower that the purpose of this utility model provides a kind of cost, makes simply the roller-mill bearing that fabrication cycle is short.
The purpose of this utility model will and be described by following detailed description and further represent.
A kind of roller-mill bearing that has oil sealing of the utility model, its structural feature is: by an outer ring 1, inner ring 5, two line column rollers 2, retainer 3, a steel snap ring 4 and two oil sealings 6 are formed, and steel snap ring 4 is made by spring steel, and ring also has opening.There is annular slot at inner ring 5 middle parts.Steel snap ring 4 is packed in the inner ring 5 middle part annular slots.Oil sealing 6 is pressed on the internal diameter of both sides rib of outer ring 1, the rib internal diameter is manufactured with spacing system mouth, spacing to rotary shaft oil seal, the raceway of the main lip of rotary shaft oil seal 6 internal diameters and secondary lip and bearing inner race 5 forms sealing pair, thereby whole roller-mill bearing is played seal action.
Compare with the existing product technology, the utility model has the advantages that:
Bearing has self-seal device, this the device for axially, radially multiple spot lip seal, be greatly improved compared with prior art bearing lubrication condition, bearing can be turned round under bad working environment safely and reliably, avoided the modal accident of rolling mill---bearing burns because of the accident that has entered reasons such as water and hammer scale and cause, make the carefree running of bearing, improved the steel rolling operation rate.Sealing configuration makes to lubricate guarantee, has improved the wear-out life of bearing effectively.Inseparable structure makes bearing race can arrange full roller (not self-locking), removes retainer simultaneously, has improved the bearing capacity of bearing greatly, has prolonged the fatigue life of bearing, in rolling processing Bearing Consumption is obviously reduced, and has reduced cost of production.
And the utility model adopts the common standard oil sealing, need not make production in addition specially, and the cost of production of bearing is exceeded can be increased, and common production line can satisfy the production needs.
Description of drawings
Fig. 1 has the structural representation of the roller-mill bearing of oil sealing for the utility model.
Among the figure: symbol 1 is represented the outer ring; Symbol 2 is represented cylindrical roller; Symbol 3 is represented retainer; Symbol 4 is represented the steel snap ring, and symbol 5 is represented inner ring; Symbol 6 is represented oil sealing.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in the figure, steel snap ring 4 is made by spring steel, and ring also has opening.During assembling, opening is strutted, in the annular slot that the bearing inner race 5 middle part raceways of packing into are produced.Be clamped on inner ring 5 middle raceways after the snap ring opening draws in and play a part spacingly, bigger axial displacement is arranged, exempt from seal failure to prevent bearing inner race 5.
Other gets two rotary shaft oil seals 6, and its external diameter is with interference fit, is pressed into by external force on the internal diameter of both sides rib of bearing outer ring 1, and the rib internal diameter is manufactured with spacing system mouthful, and is spacing to rotary shaft oil seal.The raceway of the main lip of rotary shaft oil seal 6 internal diameters and secondary lip and bearing inner race 5 forms sealing pair, thereby whole roller-mill bearing is played seal action.
Rotary shaft oil seal can adopt standard GB 9877.1～9877.3---the standard measure of 1988 defineds, also can make according to the relative dimensions of bearing.
Claims (1)
1, a kind of roller-mill bearing that has oil sealing, comprise outer ring, inner ring, cylindrical roller, retainer, steel snap ring, it is characterized in that: also comprise oil sealing, oil sealing is pressed on the internal diameter of both sides rib of outer ring, the rib internal diameter is manufactured with spacing system mouth, spacing to rotary shaft oil seal, the main lip of rotary shaft oil seal internal diameter and the raceway of secondary lip and bearing inner race form sealing pair.
