Abstract
What the utility model patent related to is bearing, is more specifically noncontact seal type double-row full-complement cylinder roller bearing.It comprises bearing outer ring, bearing inner race, roller, between bearing outer ring and bearing inner race, the outside of roller is provided with dust cover, is provided with groove between dust cover top and bearing outer ring ball track, is provided with spring ring in groove.The utility model noncontact seal type double-row full-complement cylinder roller bearing, adopt dust cover and spring ring to replace easily aging rubber seal, through long-term use, test, can meet the usage requirement of the extra high production sites of operating temperature such as steel rolling mill, steel works completely, can save a large amount of device maintenance, maintenance time, and save maintenance cost.
Description
Technical field
What the utility model patent related to is bearing, is more specifically noncontact seal type double-row full-complement cylinder roller bearing.
Background technique
Full-complement cylinder roller bearing is compared maximum difference with common cylindrical roller be that the roller quantity that is equipped with is maximum, between roller without the retainer of isolation.The in the situation that of same internal diameter and width, full-complement cylinder roller bearing has lower depth of section conventionally, and bearing has high radially bearing capacity, and can save space.Thereby be widely used in speed reducer and the handling machinery industry of automobile gearbox, engineering machinery.
The bearing structure of existing double-row full-complement band rubber seal as shown in Figure 2, what adopt is that the rubber seal 5 of contact-type is installed between bearing outer ring 1 and bearing inner race 2, it has dustproof and antifog performance, good sealing effect, but owing to being rubber seal, in the higher work-yard of operating temperature, as steel rolling mill, steel works etc., rubber seal is easily aging, and working life is shorter, the major defect that maintenance cost is higher.
Model utility content
The purpose of this utility model is to provide noncontact seal type double-row full-complement cylinder roller bearing.
The purpose of this utility model is achieved through the following channels: a kind of noncontact seal type double-row full-complement cylinder roller bearing, it comprises bearing outer ring, bearing inner race, roller, between bearing outer ring and bearing inner race, the outside of roller is provided with dust cover, between dust cover top and bearing outer ring ball track, be provided with groove, in groove, be provided with spring ring.
The utility model noncontact seal type double-row full-complement cylinder roller bearing, adopt dust cover and spring ring to replace easily aging rubber seal, through long-term use, test, can meet the usage requirement of the extra high production sites of operating temperature such as steel rolling mill, steel works completely, can save a large amount of device maintenance, maintenance time, and save maintenance cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model structural representation;
Fig. 2 is existing full-complement cylinder roller bearing structural representation;
In figure, bearing outer ring 1, bearing inner race 2, groove 3, roller 4,, spring ring 6, rubber seal 5, dust cover 7.
Embodiment
As shown in Figure 1, a kind of noncontact seal type double-row full-complement cylinder roller bearing, it comprises bearing outer ring 1, bearing inner race 2, roller 4, between bearing outer ring 1 and bearing inner race 2, the outside of roller 4 is provided with the dust cover 7 that metallic material is made, between dust cover 7 tops and bearing outer ring 1 raceway, be provided with groove 3, in groove 3, be provided with spring ring 6.
Between dust cover top and bearing outer ring ball track, there is slight clearance, not directly contact between them, the elastic steel traveler that is arranged on dust cover front relies on its elasticity that dust cover is fixed in the groove on outer ring raceway.Although dust cover and outer ring raceway face have a small amount of gap, but still can play, prevent that the dust of bearing outside from entering in bearing, also can prevent that the lubricating grease of bearing inside from overflowing.Through actual use for many years, the double-row full-complement cylinder roller bearing of this of noncontact seal kind of new structure can meet at operating ambient temperature very high completely, and the crane gear of office work is as the requirement on sheave block.Be particularly suitable for needing the hot environments such as the steel rolling mill of continuous operation, iron works.This novel bearing has more long service life, the simple feature of maintenance management.If bearing need to be in long-term operation continuously, necessary supplemental lubrication fat, it is to inject from bearing bore diameter middle part oilhole that common lubricating grease injects.
The above; it is only embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
