Abstract

A double-row spherical roller bearing unit with an eccentric lock sleeve comprises a bearing inner ring, a bearing outer ring and double rows of rollers, wherein the bearing outer ring is sleeved with a bearing seat, and a clamp spring and a seal assembly are sequentially arranged from inside to outside on the inner wall of the bearing seat positioned at the two ends of the bearing; the seal assembly comprises a metal frame and a rubber ring stuck to the inner side of the metal frame; a convex shoulder extends out of one side of the bearing inner ring and is exposed out of the bearing seat; the outer wall of the convex shoulder is sleeved with an eccentric lock sleeve, and the pore diameter of the inner wall of the eccentric lock sleeve is identical to the pore ring of the bearing inner ring; and a screw used for preventing the eccentric lock sleeve from reversing is arranged on the eccentric lock sleeve. The double-row spherical roller bearing unit is suitable for bearing heavier load in a special mounting space, and has the characteristics of convenience in installation and replacement and prolonged service life.

Description

The biserial spheric roller bearing unit of band Camlock cover

[technical field]

The utility model relates to a kind of bearing unit of forming with biserial spheric roller bearing and integrated bearing support.

[background technique]

The bearing capacity of biserial spheric roller bearing is big more than the two-row ball bearing with same axial sectional dimension, often is applied to requiring to move reliably and with long-term, bear the open-air application of condition harshnesses such as heavy duty, convenient many dirt of installing and changing, Duo Shui, many pollutions.The rolling bearing units that use under present this condition, many by forming with biserial spheric roller bearing, subdivision seat, positioning device, Sealing and the protective housing etc. of axle interference fit, the element of component units is many, complex operation, difficulty when installation, replacing bearing, and institute takes up space big.The rolling bearing units unit that the utility model provides, by integrated high strength cast iron seat and itself have the high load capacity spheric roller bearing (bearing core) of Camlock device and the skeleton black box that can adapt to the aligning demand and have an opposing external pressure is construed as, provide the desirable bearing configuration of bearing heavier load in a kind of simple in structure, economy, the specific installing space of reliable sealing.

[model utility content]

The purpose of this utility model is to be to overcome the deficiencies in the prior art, provides a kind of being applicable in the specific installing space to bear heavier load, and convenient installation and replacing improve the biserial spheric roller bearing unit of the band Camlock device in working life.

In order to solve the technical problem of above-mentioned existence, the utility model is taked following technical proposals:

A kind of biserial spheric roller bearing unit with Camlock cover includes inside and outside circle of bearing and biserial roller, is set with bearing support on bearing outer ring, at the bearing support inwall that is arranged in the bearing two ends by being disposed with jump ring and black box outward; The sealing assembly includes metal frame and the rubber ring that sticks on the metal frame inboard; Stretch out a convex shoulder in bearing inner race one side, described convex shoulder is exposed to outside this bearing support; Be set with a Camlock cover on this convex shoulder outer wall, the aperture of Camlock cover inwall is consistent with the hole circle of bearing inner race; Put at this Camlock and to be provided with the screw that prevents Camlock cover counter-rotating.

In the improvement project of the biserial spheric roller bearing unit that above-mentioned band Camlock is overlapped, on this bearing support, be provided with the oil nozzle that is used for to the interpolation of the bearing in it lubricant oil.

Compared with prior art, 1), be set with bearing support on bearing outer ring of the present utility model have a following advantage:, at the bearing support inwall that is arranged in the bearing two ends by being disposed with jump ring and black box outward, black box is made up of metal frame and rubber, can prevent effectively that foreign from entering, stoping internal grease to leak outside and resist external pressure, protection bearing and then the working life of improving bearing unit; 2), after the rotation that is provided with Camlock cover on the bearing inner race outer wall tightens or unclamps bearing inner race the dismounting roller bearing, this greatly facilitates the easy to loading and unloading of biserial spheric roller bearing unit; 3) be attached to the rotary seal pair of forming between rubber ring on the black box metal frame inboard and bearing inner race outer wall, have the feature that adapts to bearing aligning demand.

Below in conjunction with the drawings and specific embodiments the utility model is further specified:

[description of drawings]

Fig. 1 is the utility model embodiment's a structural representation;

Fig. 2 is the right elevation of Fig. 1.

[embodiment]

The utility model is a kind of biserial spheric roller bearing unit with the Camlock cover, as shown in Figure 1, include in the bearing, outer ring 1,2 and biserial roller 3, on bearing outer ring 2, be set with bearing support 4, at bearing support 4 inwalls that are arranged in the bearing two ends by being disposed with jump ring 5 and black box 6 outward, wherein jump ring 5 is control amount of floatings when being used for positioning bearing or bearing unit the axial float demand being arranged, and black box 6 can prevent that extraneous dust from entering in the bearing, thereby improve the working life of bearing unit, include metal frame 61 and the rubber ring 62 that sticks on the metal frame inboard at this black box 66, their form the rotary seal pair that can adapt to bearing aligning demand.Stretch out a convex shoulder 11 in bearing inner race 1 one sides, described convex shoulder 11 is exposed to outside this bearing support 4, is set with Camlock cover 7 on this convex shoulder outer wall, and the aperture of Camlock cover inwall is consistent with the hole circle of bearing inner race; On this Camlock cover 7, be provided with the screw 8 that prevents the counter-rotating of Camlock cover.When being installed to the utility model on the axle, just can locking bearing inner race and axle by rotating the Camlock cover, thereby bearing unit is fixed on the axle like this, tightening the screw 8 prevents to unclamp bearing inner race after the counter-rotating of Camlock cover again; As can be seen, the utility model is to tighten or unclamp dismounting roller bearing behind the bearing inner race by the rotation that is arranged on the Camlock cover on the bearing inner race outer wall, bearing support links with the matrix adopting bolt, and is simple and convenient, and this greatly facilitates the loading and unloading of biserial spheric roller bearing unit.

As shown in Figure 1, on bearing support 4, be provided with the oil nozzle 9 that is used for to the interpolation of the bearing in it lubricant oil, can further improve the working life of bearing unit like this.
