Abstract
The invention discloses an integral sealed double-row tapered roller bearing, and belongs to the technical field of rolling mill roller bearings. The integral sealed double-row tapered roller bearing comprises two outer rings (2), an inner ring (6), a space ring (4), two retainers (3) and a plurality of rollers (5), wherein the plurality of rollers (5) are positioned between the outer rings (2) and the inner ring (6); the rollers (5) are separated uniformly by the retainers (3); and the space ring is arranged between the two outer rings (2). The integral sealed double-row tapered roller bearing is characterized by also comprising a seal assembly (1) which is fixed on the outer rings; the interior of the seal assembly (1) is provided with a steel frame structure, and the exterior of the seal assembly (1) is coated with fluorous rubber, and the lip part, which is in contact seal with the inner ring (6), of the fluorous rubber is provided with a fastening spring. According to the invention, the bearing capacity of the bearing is improved, the space occupied by a seal piece is reduced, and the problem of loose sleeve of the bearing the problem that the bearing is not convenient to install, and the like are solved.
Description
Technical field
The double-row conical bearing of integral seal of the present invention belongs to the rolling mill roll technical field of bearings, is mainly used in steel industry, uses on rolling mill roll.
Background technique
Roller-mill bearing is a thrust bearing, does not generally have seal arrangement, and therefore, bearing inside enters pollutants such as impurity and water through regular meeting, to the inhibition that lubricated of bearing, and then has reduced working life of bearing; Simultaneously, do not have seal arrangement, the lubricating grease or the lubricant oil of bearing inside leak outside easily, increase the user cost of bearing.
In sum, provide that a kind of can to prevent that impurity from entering the double-row conical bearing that bearing inside can prevent that again lubricant oil from leaking outside imperative.
Summary of the invention
Enter impurity easily in order to solve existing bearing inside, lubricant oil leaks outside, and bearing load carrying capacity is low, and problems such as inconvenience are installed, and the invention provides a kind of double-row conical bearing of integral seal.
The technological scheme that technical solution problem of the present invention is adopted is as follows:
The double-row conical bearing of integral seal, comprise two outer rings, inner ring, spacer ring, two retainers, a plurality of roller, roller is between outer ring and inner ring, and retainer is evenly separated roller, and spacer ring places between two outer rings, it is characterized in that, this bearing also comprises black box, and black box is fixed on the outer ring, and black box inside is steel frame construction, the outside scribbles fluorine rubber, and the lip place of itself and inner ring contact seal is provided with garter spring.
The invention has the beneficial effects as follows: the both sides sealing assembly has improved the bearing capacity of bearing by forming one with the outer ring, has reduced the shared space of Sealing; Increase black box, can prevent that impurity from entering bearing inside, prevented that lubricant oil from leaking outside, avoided the generation of problems such as the bearing sequence of sanqu songs within a particular musical mode, installation inconvenience.
Description of drawings
Fig. 1 is the structural representation of the double-row conical bearing of integral seal of the present invention.
Among the figure: 1, black box, 2, the outer ring, 3, retainer, 4, spacer ring, 5, roller, 6, inner ring.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in further details.
As shown in Figure 1, the double-row conical bearing of integral seal of the present invention, comprise black box 1, two outer rings 2, inner ring 6, spacer ring 4, two retainers 3, a plurality of roller 5, roller 5 is between outer ring 2 and inner ring 6, retainer 3 is evenly separated roller 5, and spacer ring 4 places between two outer rings 2.Black box 1 is fixed on the outer ring 2, and is not easily separated.There is Steel Skeleton black box 1 inside, and the outside is coated with fluorine rubber, and the lip place of itself and inner ring contact seal is provided with a garter spring, prevents that foreign from entering in the bearing, prevents that again bearing internal lubrication fat or lubricant oil from leaking outside.
According to the basic boundary dimension of bearing, under the prerequisite that satisfies the bearing seal requirement, the present invention can improve the bearing capacity of bearing as much as possible, reduces the shared space of Sealing, reduces the various parts that separate, user friendly installation and use.
The double-row conical bearing of integral seal of the present invention, both sides sealing assembly 1 has increased the bearing capacity of bearing by forming one with outer ring 2, has avoided the generation of problems such as the bearing sequence of sanqu songs within a particular musical mode, installation inconvenience.
