NTN - Tolerance Design of Logarithmic Roller Profile in CRB

Witryna1 wrz 2006 · A logarithmic profile is essentially an optimal geometry for rolling machine elements such as bearing rollers and raceways which yields lower stresses to give … WitrynaA logarithmic profile is essentially optimal crowning geometry for rolling machine elements such as bearing rollers and raceways. Although some design methods of the profile have been proposed, they do not refer to the tolerance of the geometry required in engineering applications and in production.

Logarithmic Profiles of Rollers in Roller Bearings and ... - NTN

Witrynaimprove roller bearing lives within the same envelope dimensions. The cross -section of roller profile controls the pressures distribution in the contact area and radically affects the bearing basic dynamic load rating and rating lives, [1-3]. Consequently, the primary target was to reduce stresses in the roller raceway contact by modifying ... Witryna17 gru 2011 · Tangent (1 minute) = c/L Where: c = Concentricity L = Distance between the bearing centers From that: C = 12 inches x tan (1/60 degree) = 0.003 inches If the bores in this example are concentric within 3-mils (not much!), the bearings would be operating within an allowable misalignment. Witryna2 cze 2024 · And two types of logarithmic crowning models for the roller profile design were theoretically deduced, in which design redundancy was considered through the … the old fisherman story
