...Jing Liu; Zidan Xu; Chenyu An Cylindrical roller bearings (CRBs) are key components of mechanical transmission systems. The internal load distribution and stiffness (LDAS) have significant effects on the bearing fatigue life and vibrations. It can also affect the precision, reliability, and service...

... the gear tooth bending deflection. Based on the tooth deformation calculation model and accounting for initial surface separation, a variational framework is developed to simultaneously solve for load distribution and gear tooth deformation. This is followed by calculation of contact stress, bending stress...

... and the balls is also calculated with considering the non-normal load distribution caused by the spindle deflection and the roller tilt. The bearing load and life calculation results are compared with those calculated by the traditional method in which the deflection of the bearing spindle and the roller tilt...

...David J. Murphy; Thierry A. Blanchet The load applied to a lead screw assembly is distributed amongst the engaged threads of its wearing nut in a manner that can range from highly nonuniform to nearly uniform. Nonuniform load distributions can arise when new or unworn threads are initially placed...

... advantages when many contacts have to be evaluated several times, e.g., in static load distribution calculations and dynamic simulations. In Fig. 11 , the pressure distribution for a tilting angle of θ=0.86 mrad≈0.05 deg is compared with the results of de Mul et al. 9 . Some values from the reference...
