Abstract
A kind of single-row tapered roller bearing sealing element, sealing element is fixed on the outer end of the inner ring of single-row tapered roller bearing by inserts, inserts has a portion that reclines to recline with the periphery and outer end face of the outer end of inner ring, and the lower end package of sealing element extends to the bottom in the portion that reclines and in sealing contact with the outer end face of the inner ring；The inside of the upper end of the sealing element has the extension for extending to the end face direction of the outer ring of single-row tapered roller bearing and contacting with the end face seal of outer ring, and the inner sidewall connection in sealing contact of the shell of single-row tapered roller bearing is fixed in the top of sealing element and support.By the seal chamber for being wrapped to form a package bearing retainer of sealing element, to play the effect of sealing.The utility model sealing space is small, can reduce sealing space.The leeway of the space allocation of product whole design is big, can be very good the loss of protection lubricating grease, improves the utilization rate of lubricating grease, improve the lubricating condition of bearing, improve the service life of product.
Description
Technical field
The utility model belongs to tapered roller bearing accessories field, especially with a kind of single-row tapered roller bearing sealing element
It is related.
Background technique
Existing single-row tapered roller bearing itself is mounted on shell 1 ' without sealing element as shown in Figure 1, needing to rely on
Sealing element 2 ' be sealed, the shortcomings that this sealing element is installed on tapered roller bearing, is: grease under conditions of grease lubrication
Sealing space is larger, and grease loss late is also higher.
Utility model content
For existing issue, the utility model is intended to provide a kind of single-row tapered roller bearing sealing element.
For this purpose, the utility model uses following technical scheme: a kind of single-row tapered roller bearing sealing element, feature
That the sealing element is fixed on the outer end of the inner ring of single-row tapered roller bearing by inserts, the inserts have with it is interior
The lower end package in the portion that reclines that the periphery and outer end face of the outer end of circle recline, the sealing element extends to described recline
The bottom in portion is simultaneously in sealing contact with the outer end face of the inner ring；The inside of the upper end of the sealing element has to single-row circular cone
The extension that the end face direction of the outer ring of roller bearing extends and contacts with the end face seal of outer ring, the top of sealing element and support
The inner sidewall connection in sealing contact of the shell of fixed single-row tapered roller bearing.A package axis is wrapped to form by sealing element
The seal chamber of retainer is held, to play the effect of sealing.
As supplement to above-mentioned technical proposal and perfect, the utility model further includes following technical characteristic.
The end face of the extension and the top of sealing element have tapered portion, pass through the tapered portion end with outer ring respectively
The inner sidewall of face and shell is pressed against deformation, to play good sealing effect.
The inserts in counterclockwise rotation 90 Ω shape, the sealing element have insertion inserts on the right side of end face with
And the embedded part of inner cavity guarantees the Assembly stability of sealing element to improve the fixed effect of inserts and sealing element, inserts
The bottom surface of the convex portion of left side lower end and inserts and the inner ring recline installation.
The utility model can achieve it is following the utility model has the advantages that the utility model by by sealing element directly with the inner ring of bearing
Cooperation contact is sealed with outer ring, to play the role of end face seal, the top of sealing element is contacted with the shell of installation, is also functioned to good
Good sealing function.The utility model sealing space is small, can reduce sealing space.The space allocation of product whole design it is remaining
Ground is big, can be very good the loss of protection lubricating grease, improves the utilization rate of lubricating grease, improves the lubricating condition of bearing, improves and produces
The service life of product.
Detailed description of the invention
Fig. 1 is the assembling structure schematic diagram of existing sealing element.
Fig. 2 is the assembling structure schematic diagram of the utility model.
Fig. 3 is the structural schematic diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawing.
As Figure 2-3, the sealing element 1 of the utility model is fixed on the inner ring 3 of single-row tapered roller bearing by inserts 2
Outer end, inserts has the portion 21 that reclines to recline with the periphery and outer end face of the outer end of inner ring, the lower end package of sealing element
The bottom in the portion 21 that reclines extended to is simultaneously in sealing contact with the outer end face of inner ring；The inside of the upper end of sealing element 1 has to single-row
The extension 11 that the end face direction of the outer ring of tapered roller bearing extends and contacts with the end face seal of outer ring 4, the top of sealing element 1
The inner sidewall connection in sealing contact of the shell 5 of portion and the fixed single-row tapered roller bearing of support.
Preferably, the end face of extension 11 and the top of sealing element have tapered portion, by tapered portion respectively with outer ring
End face and shell inner sidewall be pressed against deformation, to play good sealing effect.
Further, inserts 2 in counterclockwise rotation 90 Ω shape, sealing element 1 have insertion inserts on the right side of end face with
And the embedded part of inner cavity guarantees the Assembly stability of sealing element to improve the fixed effect of inserts and sealing element, inserts
The bottom surface of the convex portion of left side lower end and inserts and inner ring recline installation.
