In 1991, Needelman and Zaretsky presented a set of empirically
derived equations for bearing fatigue life (adjustment) factors (LFs) as a function of oil filter ratings.
Tapered roller bearings can be set at initial machine assembly to any desired axial or radial clearance. This unique feature enables a designer to control bearings to meet anticipated application operating conditions, and thereby provide
optimum bearing and system performance.
Is there a gear software package out there that will calculate the design of spur, helical, worm, and planetary gearsets? Also, we would like a program that calculates stresses and material selection. Finally, we would like to have the program calculate bearings loads, too. Thank you for your help.
Tooth contact analysis (TCA) is an important tool directed to the determination of contact patterns, contact paths, and transmission errors in gear drives. In this work, a new general approach that is applicable to any kind of gear geometry is proposed.
Excellence Awards Competition, sponsored by the Metal Powder Industries Federation, were
recently announced at the POWDERMET2015
International Conference on Powder Metallurgy & Particulate Materials. Receiving grand prizes
and awards of distinction, the winning parts are examples of
PM’s precision, performance, complexity, economy, innovation
and sustainability. The winning parts show how customers from around the world are taking advantage of PM’s
design advantages.
