Inhalt: Übliche Kegelrollenlager zeichnen sich durch eine im Vergleich zu Spindellagern sehr hohe Steifigkeit und Tragfähigkeit aus. Gleichzeitig ist ihre Drehzahleignung deutlich geringer, was den Einsatz in Werkzeugmaschinen-Hauptspindeln zur Fräsbearbeitung in den meisten Fällen ausschließt. Mit dem hier vorgestellten zweistufigen Verfahren wird ein Kegelrollenlager für den Betrieb bei hohen Drehzahlen ausgelegt. Im ersten Schritt erfolgt die Auslegung der Makrogeometrie durch Lösung eines Optimierungsproblems. Zur Auslegung der Mikrogeometrie kommen in zweiten Schritt Methoden zur Kontaktberechnung und -beschreibung zur Anwendung.

This paper presents an analytical study of the load distribution in a tapered roller bearing operating at a high speed and under combined loading. The friction forces at the rolling contacts and the cage forces are not considered. A numerical example showing, among other things, the effects of misalignment and speed on the bearing fatigue life and the sliding velocity at the flange contact is given.

Three methods to calculate distribution of internal load in tapered roller bearing are introduced in the present paper. Distributions of internal load in tapered roller bearing used in axle box of High Speed Train have been calculated by continuous function model (conventional method), discrete function model method and finite element method according to the internal load distribution theory of rolling bearing. The results of three methods show that the pattern of the internal load distributions is same, but the accuracy is not same. The accuracy of radial load of the bearing with finite element method is highest, the accuracy with discrete model method is higher and the accuracy with discrete model method is lowest. The discrete function model is not only with the higher accuracy but also convenient to be used widely in practice through the program of dichotomie numerical method.

Taking the type of a double-row tapered roller bearing of a high speed railway passenger coach as research object, the analysis for tapered roller with logarithmic profile has been done. Through the comparison of contact stresses at different crowning values by the finite element software has been done, the best crowning value has been got. There is a certain error between the theory of crowning value and the best crowning value by researching.

The performance of 120.65-mm (4.75-in.) bore high-speed design tapered roller bearings was investigated at shaft speeds of 20,000 rpm (2.4 million DN) under combined thrust and radial load. The test bearings design was computer optimized for high-speed operation. Temperature distribution and bearing heat generation were determined as a function of shaft speed, radial and thrust loads, lubricant flow rates, and lubricant inlet temperature. The high-speed design tapered roller bearing operated successfully at shaft speeds up to 20,000 rpm under heavy thrust and radial loads. Bearing temperatures and heat generation with the high-speed design bearing were significantly less than those of a modified standard bearing tested previously. Cup cooling was effective in decreasing the high cup temperatures to levels equal to the cone temperature.
