Abstract

The utility model relates to an integral sealed double-row TRB (tapered roller bearing), which belongs to the technical field of rolling bearings of rolling mills. The bearing includes two outer rings (2), an inner ring (6), a separation 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 evenly separated by the retainers (3); and the separation ring (4) is arranged between the two outer rings (2). The bearing is characterized by further comprising a sealing component (1) fixed on the outer rings (2), a steel frame structure is arranged inside the sealing component (1), the outer part is coated with fluorous rubber, and a clamping spring is arranged at a lip where the sealing component and the inner ring (6) are contacted and sealed. The utility model improves the bearing capability of the bearing, reduces the space occupied by the sealing component, and solves the problems that the bearing is sleeved loosely, the installation is inconvenient, and the like.

Description

A kind of double-row conical bearing of integral seal

Technical field

The double-row conical bearing of the utility model integral seal 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.

The model utility content

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 utility model provides a kind of double-row conical bearing of integral seal.

The technological scheme that the utility model technical solution problem is adopted is as follows:

A kind of 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 beneficial effects of the utility model are: 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 the utility model integral seal.

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 utility model is described in further details.

As shown in Figure 1, the double-row conical bearing of integral seal of the present utility model, 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 utility model 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 the utility model integral seal, 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.

Claims

1. the double-row conical bearing of an integral seal, comprise two outer rings (2), an inner ring (6), a spacer ring (4), two retainers (3) and a plurality of roller (5), described a plurality of roller (5) is positioned between outer ring (2) and the inner ring (6), retainer (3) is evenly separated roller (5), spacer ring (4) places between two outer rings (2), it is characterized in that, this bearing also comprises black box (1), black box (1) is fixed on the outer ring (2), black box (1) inside is steel frame construction, and the lip place of itself and inner ring (6) contact seal is provided with garter spring.
