Abstract
The utility model relates to a rubber-wrapped cutting roller, comprising an outer ring, an inner ring and a ball, wherein the ball is disposed between the inner ring and the outer ring; a rubber layer is wrapped on the outer circle surface of the outer ring; the end surface length of the outer ring is greater than the diameter of the ball; grooves are disposed at the both inside ends of the outer ring; the grooves are jointed with one end of the U-shaped bent surface of a sealing cover; the other end of the sealing cover is jointed with the inner ring; and a retainer filled with the ball is disposed between the sealing covers. The rubber-wrapped cutting roller disclosed by the utility model is light and handy in structure and capable of being widely applied to various process line occasions needing to usually carry and demanding a light weight of conveyer.
Description
Technical field
The utility model relates to the logistics equipment field, relates in particular to encapsulate formula cutting roller.
Background technique
Roller bearing capacity radially is all bigger, and each accessory replaceability is strong, increasing being applied in the various logistics equipment system.Roller generally is used for the rolling on the sliding rail.Existing roller generally adopts the standard rolling bearing structure, and bearing is made up of inner ring, outer ring, rolling element and retainer.But there is following shortcoming in this standard rolling bearing structure:
(1) poor sealing performance in the using process can influence working life of bearing, reduces the usability of bearing;
(2) inner ring of bearing is parallel and equal with the end face of outer ring, and axially locating need add the axle sleeve that matches with bearing when installing, and has increased cost;
(3) complex structure, difficult installation, cost is high.
(4) outer ring of bearing is a metal layer, and after the long-term work process was hit, outer ring damage easy to wear influenced the roller proper functioning.
The model utility content
The applicant is to the bearing seal poor performance that above-mentioned roller of the prior art adopted, and axially locating need add shortcomings such as axle sleeve when installing, a kind of rational in infrastructure, easily manufactured encapsulate formula cutting roller is provided, and it has good sealing property and reliability.
The technological scheme that the utility model adopted is following:
A kind of encapsulate formula cutting roller comprises outer ring, inner ring, ball; Ball is arranged between inner ring and the outer ring, and the periphery of outer ring is enclosed with glue-line, and cycle surface length is greater than ball diameter; Inboard two ends, outer ring have groove; Groove and sealing cover U-shaped flexure plane one termination are closed, and the other end of sealing cover engages inner ring, and the retainer that ball is housed is set between the sealing cover.
Its further technical characteristics is:
Said outer ring is " T " shape.
The beneficial effect of the utility model is following:
Through behind bearing outer ring periphery parcel glue-line, during proper functioning, glue-line absorption portion impact force, the protection product in the working life of having improved bearing, has reduced the cost of product.And bearing inner race end face length is greater than said cycle surface length, when the length of axle during greater than the inner ring length of bearing, then do not need extra use axle sleeve to carry out the axial restraint of bearing again, practiced thrift cost.The utility model structure is light and handy, can be widely used in all kinds of needs and often move, requires the lightweight process line occasion of conveyor.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described.
As shown in Figure 1, the described encapsulate formula cutting of the utility model roller comprises outer ring 2, inner ring 5, ball 4; Ball 4 is arranged between inner ring 5 and the outer ring 2, and the periphery of outer ring 2 is enclosed with glue-line 1, and glue-line 1 adopts rubber material; Glue-line 1 is the absorption portion impact force when work, improves bearing life.Outer ring 2 end face length are greater than ball 4 diameters, and 2 inboard two ends, outer ring have groove, and U-shaped flexure plane one termination of groove and sealing cover 6 is closed, and U type flexure plane prevents that effectively dust and impurity from getting into bearing, influences the proper functioning of bearing.The other end of sealing cover 6 engages inner ring 5, and the retainer 3 that ball 4 is housed is set between the sealing cover 6.
During actual manufacturing; After machining bearing outer ring 2, inner ring 5, retainer 3, sealing cover 6,2 periphery parcel glue-line 1 has promptly been accomplished the installation of the utility model in the outer ring; So easy processing can obtain good airproof performance, reliability is high, impact-resistant the utility model.
More than describing is the explanation to the utility model, is not the qualification to model utility, and the utility model institute restricted portion is referring to claim, and under the situation of the spirit of the utility model, the utility model can be done any type of modification.
Claims (2)
1. an encapsulate formula cutting roller comprises outer ring, inner ring, ball; Said ball is arranged between inner ring and the outer ring, it is characterized in that: the periphery of said outer ring is enclosed with glue-line, and cycle surface length is greater than ball diameter; Inboard two ends, outer ring have groove; Groove and sealing cover U-shaped flexure plane one termination are closed, and the other end of sealing cover engages inner ring, and the retainer that ball is housed is set between the sealing cover.
2. encapsulate formula cutting roller as claimed in claim 1, it is characterized in that: said outer ring is " T " shape.
