Description
Technical Field
The utility model belongs to the field of large bearings, and provides a novel four-row tapered roller bearing with a basket-shaped frame with a nonstandard inner diameter 409.575. The special bearing is mainly used for supporting rollers and working rollers on rolling mills in metallurgical steel and nonferrous industries. Belongs to engineering element bearings (F16C) and metal rolling (B21B).
Background
In the existing ferrous metallurgy industry, the four-row tapered roller bearing which is used for bearing radial load or bearing radial and axial combined load and is used for rolling mill supporting rollers or working rollers in the nonferrous industry, the bearing has the advantages of short service life, long accumulated auxiliary time for roller changing consumption, and long service life because of severe working condition, high rotating speed and large impact load.
Concept of bearing life:
broadly, the life of a bearing is the life of the bearing. When the bearing is fatigued, broken, severely worn, burned, plastic indentation, loss of accuracy, vibration, noise deterioration, etc., this means the end of life. It should be noted that in most normal use cases, the failure mode of the bearing should be fatigue failure of the rolling surface of the bearing component. The basic rated life formula of the radial roller bearing is:
L 10 : basic rated life, millions of revolutions
Cr: radial base rated dynamic load, N
Pr: radial equivalent dynamic load, N
As can be seen from the formula, pr is determined by the working condition of the bearing, and Cr is the only factor for determining the service life of the bearing, regardless of the working condition of the bearing. The size of the rated dynamic load Cr of the bearing in a sense determines the length of the service life of the bearing.
In the field of four-row tapered roller bearing design, the bearing structure is mature, and core technologies of various large manufacturers fall on the design of specific dimensional parameters of roller diameter Dw (millimeters), roller length L (millimeters), roller number Z and roller half cone angle psi. Because the external dimensions of the four-row tapered roller bearing are customized by a purchaser, namely, the dimensional parameters of the internal diameter D, the external diameter D, the internal width B and the external ring assembly width T are required by the purchaser, and then the structural elements of the four-row tapered roller bearing are designed by a designer to take values, namely, the specific diameter Dw, the length L of the rollers, the number Z of the rollers and the half taper angle psi of the rollers, so that different manufacturers can take different values on the same external dimensions of the bearing proposed by customers, and the values of the designed structural elements of the bearing are factors for determining the dynamic load (common knowledge in the field).
Novel four-row tapered roller bearing with non-standard width 272 of basket-shaped frame of Chinese patent utility model "
(CN 201921022114.0) although a four-row tapered roller bearing is disclosed, it discloses only one type, however, when the purchaser puts forward a demand on the external dimension of a new bearing, it is necessary to redesign the value of the structural element of the bearing, so that the requirement of long service life of the novel four-row tapered roller bearing under the new dimension can be met.
Disclosure of Invention
The utility model aims to solve the problem that the bearing structural elements are required to be redesigned to take values on the aspect of the appearance size of a new bearing, and high dynamic load is met so as to prolong the service life of the bearing.
In order to achieve the above purpose, the present utility model adopts the following technical means:
basket-shaped frame non-The utility model provides a novel four-row tapered roller bearing of mark internal diameter 409.575, includes the biserial outer lane, sets up two single row outer lanes in biserial outer lane both sides respectively, is provided with outer spacer ring between single row outer lane and the biserial outer lane, still includes the interior spacer ring that sets up between two biserial inner circles, is equipped with the roller between biserial inner circle and the single row outer lane to by basket shape holder support, its characterized in that: the bearing inner diameter D of the bearing is 409.575 mm, the bearing outer diameter D is 546.1 mm, the bearing outer ring assembly width T is 334.962 mm, the bearing inner ring assembly width B is 334.962 mm, and the bearing roller diameter Dw is
Millimeter, roller length L ∈ ->
Millimeter, number of rollers Z per row +.>
The roller half cone angle ψ takes a value of 1 ° 8'±5'.
In the technical scheme, the diameter Dw of the bearing roller is 38.838 mm, the length L of the roller is 63.1 mm, the number Z of the rollers in each row is 37, and the half cone angle psi of the roller is 1 degree 8'.
The utility model has the beneficial effects that: the novel four-row tapered roller bearing with the non-standard inner diameter 409.575 of the basket-shaped frame is designed by adopting a rolling bearing limit design method which is created by a company, and the numerical value of the structural elements of the novel four-row tapered roller bearing is determined. The design realizes that the designed roller has the largest diameter, the longest length and the highest rated dynamic load value of the bearing under the condition of meeting the design strength and the technological processing requirement, the calculated service life of the bearing is the longest, the long service life requirement of a customer is met, and the use cost of the customer is reduced.
