Double-row conical bearing outer ring

Technical Field

The utility model relates to a bearing, in particular to a double-row conical bearing outer ring.

Background

Sealed double-row tapered roller bearing owing to have non-maintaining nature, can bear multiple advantages such as great footpath axial force, and the wide application is in positions such as commercial car engine brake, commercial car engine fan, wheel hub, because the bearing is at the operation in-process, because the loss of multiple reason causes lubricating grease, leads to the bearing to use the later stage to appear lubricated bad or even inefficacy.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model aims to provide a double-row conical bearing outer ring which can improve the storage effect of lubricating grease, relieve the loss and prolong the service life.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a biserial conical bearing outer lane, includes the outer lane body, sets up the slot that extends along inner wall circumference on the inner wall of outer lane body, the slot is located between the both sides position that the outer lane body corresponds biserial tapered roller.

As a further development of the utility model, the grooves are formed by cutting and/or grinding.

Alternatively, the groove is formed by stamping.

As a further improvement of the utility model, the cut-off surface of the groove is in the shape of a circular arc.

As a further improvement of the utility model, the outer surfaces of the two end parts of the outer ring body are converged to form steps, and the positions of the steps correspond to the positions for installing the sealing rings.

As a further improvement of the utility model, the bending part of the step forms a slope transition.

As a further improvement of the utility model, an annular platform is formed at the position of the outer ring body for installing the sealing ring, and a sunken annular groove is formed at one side of the annular platform corresponding to the roller.

As a further improvement of the utility model, the cut-off surface of the annular groove is in the shape of a circular arc.

The oil-saving lubricating device has the beneficial effects that the groove is formed in the inner wall of the outer ring body, so that the inner space of the assembled outer ring body and inner ring can be increased, the oil storage capacity is further improved, a longer-term lubricating effect is achieved, the lubricating time is prolonged, and the problem of rapid oil loss at present can be solved. And the position of oil storage is between two tapered roller, means the middle part that is close to the outer lane body, and the oil storage effect at this position is better, and because the roller adopts tapered roller, therefore the middle part of outer lane body is thicker, has higher intensity, through setting up the slot at this position, can avoid causing the influence to rigidity, the oil storage capacity increase at this position can conveniently carry out the fuel feeding to the roller position of both sides simultaneously, can also stabilize the fuel feeding effect under the effect that improves the oil storage.

Detailed Description

The utility model will be further described in detail with reference to the following examples, which are given in the accompanying drawings.

As shown with reference to figures 1-2,

the utility model provides a biserial conical bearing outer lane, includes outer lane body 1, set up on the inner wall of outer lane body 1 along inner wall circumference extension's slot 2, slot 2 is located between the both sides position that outer lane body 1 corresponds biserial tapered roller.

In the above scheme, through set up slot 2 on the inner wall of outer lane body 1, can increase the inner space of outer lane body 1 and inner circle equipment back, and then improve the oil reserve, reach longer-term lubricated effect, the continuation lubrication time can reduce the fast problem of present grease loss. And the position of oil storage is between two tapered roller, means the middle part that is close to outer lane body 1, the oil storage effect at this position is better, and because the roller adopts tapered roller, consequently the middle part of outer lane body 1 is thicker, has higher intensity, through setting up slot 2 at this position, can avoid causing the influence to rigidity, the oil storage capacity increase at this position can conveniently carry out the fuel feeding to the roller position of both sides simultaneously, can also stabilize the fuel feeding effect under the effect that improves the oil storage.

In particular, the grooves 2 may be formed by cutting and/or grinding, or by stamping.

The mode of cutting and polishing is comparatively commonly used, and is also more convenient, can also reduce the weight of bearing, and what bring thereupon is certain rigidity change, under needs special demands, can adopt the punching press mode to form, and the ditch groove 2 through the punching press formation can let the density near ditch groove 2 increase, and then improves the rigidity intensity. The two processing modes can be selected by a person skilled in the art according to actual requirements.

In order to maintain a balance between stiffness and volume of the groove 2, the cut-off surface of the groove 2 is rounded. The circular arc-shaped grooves 2 ensure a certain oil storage space and simultaneously avoid the situation that the rigidity of the grooves 2 is substantially influenced to cause the shortened service life.

Furthermore, in order to extend the service life of the grease, the wear is reduced. The outer surfaces of the two end parts of the outer ring body 1 are folded to form steps 3, and the positions of the steps 3 correspond to the positions for installing the sealing rings.

Generally, when the bearing is installed, the outer ring and the bearing chamber are in interference fit, and the sealing lip of the sealing element is indirectly deformed due to interference deformation, so that the sealing state of the bearing is poor, the sealing is poor, and the leakage risk of grease loss exists.

Through setting up step 3, can eliminate the extrusion to the sealing washer position during interference fit, reduce the influence to the sealed effect of sealing washer. Therefore, the sealing effect of the sealing ring can be ensured, the service life of the lubricating grease is further prolonged, and the loss caused by leakage is reduced.

Furthermore, the bend of the step 3 forms a bevel transition 4. This sets up down, can let the installation effect better, and step 3 has certain guide face, realizes the guide of assembly, can not cause the installation card to pause because of step 3's problem.

In order to further increase the oil storage capacity, an annular platform 5 is formed at the position for installing the sealing ring on the outer ring body 1, and a sunken annular groove 6 is formed at one side of the annular platform 5 corresponding to the roller.

By the design of the annular groove 6, the oil storage capacity can be further increased. Likewise, the cut-off surface of the annular groove 6 is rounded in order to balance the rigidity and the oil storage space.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the utility model may occur to those skilled in the art without departing from the principle of the utility model, and are considered to be within the scope of the utility model.
