Abstract

Long-life new self-aligning thrust roller bearing.With a seat ring, a blowout patche, there is Z roller of a row between seat ring and blowout patche, and supported by retainer, have a bushing in the lower section inner radius of blowout patche.It is big to solve existing bearing impact load, the problems such as rotating speed is high, bearing life is short, roll change elapsed time is long, using company's original creation《Limit design method for rolling bearing》, there is provided the appearance and size and structural element value of a kind of model 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 user to bearing long-life and reduction use cost.Belong to large size bearing.Make 6 roller mill intermediate calender rolls or working roll special bearing on steel and nonferrous metallurgy industry rolling mill.

Description

Long-life new self-aligning thrust roller bearing

Technical field

A kind of self-aligning thrust roller bearing, belong to large size bearing.It is mainly used in making on steel and nonferrous metallurgy industry rolling mill Intermediate calender rolls or working roll special bearing.Belong to engineering element bearing class (F16C), the rolling class (B21B) of metal.

Background technology

The self-aligning thrust roller bearing of existing steel, the roller mill intermediate calender rolls of nonferrous metallurgy industry 6 or working roll dress, with four Row tapered roller bearing pairing uses, and bears axial load.Bearing operating mode inclement condition, rotating speed is high, and the shock loading born is big. Arduously taken time when changing roll.User is reduction use cost, it is desirable to which bearing possesses the long-life.

The content of the invention

The utility model proposes long-life new self-aligning thrust roller bearing, its purpose is exactly to provide the user the long-life Self-aligning thrust roller bearing.Provide the appearance and size and structural element numerical value of a kind of self-aligning thrust roller bearing of new model. The technical scheme of use is as follows：

Long-life new self-aligning thrust roller bearing, there is a seat ring 1, a blowout patche 2, there is one between seat ring and blowout patche Z roller 4 is arranged, and is supported by retainer 3, the lower section inner radius of blowout patche 2 has a bushing 5, it is characterized in that：A kind of model axle Bearing bore diameter d, bearing outside diameter D, bearing height H, bearing roller diameter Dw, roller length L, each column roller quantity Z held is table 1 The number range of sequence number 1；

Table 1

To obtain the optimum efficiency of self-aligning thrust roller bearing, a kind of bearing bore diameter d of model bearing in table 1, outside bearing Footpath D, bearing height H, bearing roller diameter Dw, roller length L, each column roller quantity Z values are respectively the number of sequence number 1 in table 2 Value.Table 2

The utility model beneficial effect：This long-life new self-aligning thrust roller bearing, " axis of rolling created using company Hold limit design method " design, it is determined that a kind of above-mentioned structural element numerical value of model self-aligning thrust roller bearing, the design are 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 user, reduces the use cost of user.
