Milling train long lifetime novel four-row tapered roller bearing, has two single-row outer rings, a double-row outer-ring, and two biserial inner rings establish cone spacer between two inner rings, establish two outer ring spacers altogether, establish multiple roller, and have retainer between inside and outside circle between outer ring.Large for solving existing bearing impact load, rotating speed is high, bearing life is short, the problems such as roll change elapsed time is long, provide boundary dimension and the structural element value of five kinds of new model bearings, the design achieves and is meeting under design strength and processes requirement condition, the rolling element largest diameter of design, length is the longest, the dynamic load rating value of bearing is the highest, the mathematic(al) expectation of bearing is the longest, meet client to bearing length life-span and the requirement reducing user cost, belong to large size bearing, back-up roll and work roll special bearing is made on iron and steel and nonferrous metallurgy industry rolling mill.
Description
(1) technical field: a kind of four-row tapered roller bearing, belongs to large size bearing.Be mainly used in iron and steel and nonferrous metallurgy industry rolling mill make back-up roll and work roll special bearing.Belong to the rolling class (B21B) of engineering element bearing class (F16C), metal.
(2) background technique:
The four-row tapered roller bearing of existing iron and steel metallurgy, coloured industry rolling mill or work roll dress, because of bearing operating mode inclement condition, rotating speed is high, and the impulsive load of bearing is large, thus the working life of bearing is shorter, causes changing roll consumption accumulation long for auxiliary time.User, for reducing user cost, requires that bearing possesses the long lifetime.
(3) summary of the invention: the milling train that the utility model proposes long lifetime novel four-row tapered roller bearing, its object is exactly for user provides long-life four-row tapered roller bearing.Provide boundary dimension and the structural element numerical value of the four-row tapered roller bearing of five kinds of new models.
The technological scheme adopted is as follows:
Milling train long lifetime novel four-row tapered roller bearing, there are two single-row outer rings 1, a double-row outer-ring 6, two biserial inner rings 4, cone spacer 5 is established between two biserial inner rings, between single-row outer ring and double-row outer-ring, establish two outer ring spacers 2 altogether, between inside and outside circle, establish multiple roller 3, and supported by retainer 7; It is characterized in that: described novel four-row tapered roller bearing is provided with five kinds of models, bearing bore diameter d, the bearing outside diameter D of often kind of model bearing, bearing outer ring element width T, bearing inner race element width B, bearing roller diameter Dw, roller length L, often row roller quantity Z and roller half cone angle ψ span are respectively the number range in table 1 in sequence number 1-5; Table 1
For obtaining the optimum efficiency of four-row tapered roller bearing, bearing bore diameter d, the bearing outside diameter D of the novel four-row tapered roller bearing of described often kind of model, bearing outer ring element width T, bearing inner race element width B, bearing roller diameter Dw, roller length L, often row roller quantity Z and roller half cone angle ψ value to be respectively in table 2 numerical value in sequence number 1-5.
Table 2
The utility model beneficial effect: this milling train long lifetime novel four-row tapered roller bearing, " limit design method for rolling bearing " of employing company original creation, determine the structural element numerical value of above-mentioned five kinds of model four row conical bearings, the design achieves and is meeting under design strength and processes requirement condition, the rolling element largest diameter of design, length is the longest, the dynamic load rating value of bearing is the highest, the mathematic(al) expectation of bearing is the longest, meet the long life requirement of client, reduce the user cost of client.
