Abstract

Long-life new deep groove ball bearing.With an outer ring, an inner ring, there is Z steel ball of a row between outer ring and inner ring, and supported by retainer.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 is realized under the conditions of design strength and technique processing request is met, the steel ball size of design is maximum, 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 extra large size bearing.Make support roller special bearing on steel and nonferrous metallurgy industry rolling mill, match and use with four-line column roller bearing, for bearing axial load.

Description

Long-life new deep groove ball bearing

Technical field

A kind of deep groove ball bearing, belong to extra large size bearing.It is mainly used in supporting on steel and nonferrous metallurgy industry rolling mill Roller special bearing.Belong to engineering element bearing class (F16C), the rolling class (B21B) of metal.

Background technology

Existing steel, nonferrous metallurgy industry rolling mill deep groove ball bearing, make with four-line column roller bearing pairing With for bearing 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 Reduce use cost, it is desirable to which bearing possesses the long-life.

The content of the invention

The utility model proposes long-life new deep groove ball bearing, its purpose is exactly to solve bearing operating mode inclement condition, Rotating speed is high, and the shock loading born is big, is arduously taken time when changing roll, the problem of causing customer using cost high.User will Bearing is asked to possess the long-life.

Provide the user long-life deep groove ball bearing.Provide a kind of appearance and size and knot of the deep groove ball bearing of new model Structure element numerical value.The technical scheme of use is as follows：

Long-life new deep groove ball bearing, there is an outer ring 1, an inner ring 2, there are row Z between outer ring and inner ring Steel ball 4, and supported by retainer 3；It is characterized in that：Bearing bore diameter d, bearing outside diameter D, the bearing outer ring width of this kind of model bearing T=bearing inner race width B, bearing steel ball diameter Dw, each column steel ball number Z are the number range in table 1；

Table 1

。

To obtain the optimum efficiency of deep groove ball bearing, bearing bore diameter d, bearing outside diameter D, the bearing outer ring of the middle (center) bearing of table 1 are wide It is numerical value in table 2 to spend T=bearing inner race width B, bearing steel ball diameter Dw, each column steel ball number Z values.

Table 2

The utility model beneficial effect：This long-life new deep groove ball bearing, " the rolling bearing limit created using company Design method " is designed, it is determined that the structural element numerical value of the above-mentioned model long-life deep groove ball bearing, the design are realized full Under the conditions of sufficient design strength and technique processing request, the steel ball size of design is maximum, the dynamic load rating value highest of bearing, bearing Mathematic(al) expectation it is most long, meet the long life requirement of user, reduce the use cost of user.
