Abstract

Eight novel double-row taper roll bearing in strut support, by a double-row outer-ring and two single-row inner rings separated by cone spacer, multiple rollers are set between inside and outside circle, two row rollers are interior eight shapes, and are supported by post cage.To solve the problems such as existing work condition environment condition is poor, bearing load is big, and rotating speed is high, bearing life is short, using company's original creation《Limit design method for rolling bearing》Design, there is provided the appearance and size and structural element value of a kind of novel bearing, the design are realized under the conditions of design strength and technique processing request is met, the roller diameter of design is maximum, length is most long, the dynamic load rating value highest of bearing, and the mathematic(al) expectation of bearing is most long.Meet requirement of the client to bearing long-life and reduction use cost.Belong to extra large size bearing.For metallurgy industry rolling mill gear-box special bearing.

Description

Eight novel double-row taper roll bearing in strut support

(1) technical field：A kind of double-row conical bearing, belong to extra large size bearing.It is mainly used in iron and steel metallurgy industry to roll Steel machine gear-box bearing.Belong to engineering element bearing class (F16C), the rolling class (B21B) of metal.

(2) background technology：

The double-row conical bearing of existing iron and steel metallurgy industry rolling mill gear-box, because bearing operating mode environmental condition is disliked Bad, rotating speed is high, and load is big, thus the service life of bearing is shorter, and user is reduction use cost, it is desirable to which bearing possesses longevity Life.

(3) content of the invention：

The utility model proposes strut support in eight novel double-row taper roll bearings, its purpose is exactly to provide the user length The double-row conical bearing in life-span.Provide a kind of structural element numerical value of new double-row conical bearing.

The utility model is used for bearing designation 3506/536.575, wherein 35 be double-row conical bearing, 06 is indefinite Dimension series code name, 536.575 be bearing bore diameter d.Technical scheme provided by the utility model is one kind in this bearing designation Nonstandard new design.

Its technical scheme is as follows:

Eight novel double-row taper roll bearing in strut support, there is a double-row outer-ring 1 and two separated by cone spacer 5 Single-row inner ring 2；Multiple rollers 4 are set in inside and outside circle, two row roller relative positions are interior eight shapes, and are supported by post cage 3, It is characterized in that：A kind of bearing bore diameter d of model bearing, bearing outside diameter D, bearing width B1, bearing outer ring width C 1, roller diameter Dw, roller length L, each column roller quantity Z and roller half cone angle ψ span are the number range in table 1.

Table 1

To obtain the optimum efficiency of double-row conical bearing, bearing bore diameter d, the bearing outside diameter of the model bearing in table 1 D, bearing width B1, bearing outer ring width C 1, roller diameter Dw, roller length L, each column roller quantity Z and roller semi-cone angle It is respectively value in table 2 to spend ψ values.As leave out the numerical value that tolerance only has nominal dimension in table 1.

Table 2

The utility model beneficial effect：Eight novel double-row taper roll bearing in this strut support the, using " rolling of company's original creation Dynamic bearing limit design method " designs, it is determined that a kind of above-mentioned structural element numerical value of model biserial conical bearing.The design is real Showed under the conditions of design strength and technique processing request is met, the roller diameter of design is maximum, and length is most long, bearing it is specified Dynamic load charge values highest, the mathematic(al) expectation of bearing is most long, meets the long life requirement of client, reduces the use cost of client.

(4) illustrate

Eight novel double-row taper roll bearing positive view in Fig. 1 strut supports.

The shape graph of Fig. 2 rollers 4.

(5) embodiment

See Fig. 1, Fig. 2, eight novel double-row taper roll bearings in the strut support of sequence number 1, have a double-row outer-ring in table 2 1 and two single-row inner rings 2 being separated by cone spacer 5, multiple rollers 4 are set inside, between outer ring, and two row roller relative positions are interior eight Shape.Roller is supported by post cage 3.Post cage 3 is that each center of roller 4 has individual axially extending bore, is worn in through hole A pillar 3.1 is crossed, every pillar two is connected and formed with 2 rounded washers 3.2 respectively.Bearing bore diameter d is 536.575mm, bearing outside diameter D are 761.873mm, and bearing inner race width B1 is 311.35mm, and the width C 1 of bearing outer ring 1 is 247.65mm.With limit design method determine structural element size be：The roller diameter Dw of bearing is 66.416mm, roller length It is 97mm for L, it is 30 that roller sets quantity Z in circumferential each column, and roller semi-cone angle ψ is 1 ° 7 '.
