Research on the Performances of a Novel Roller Bearing-Deep Cavity Hollow Cylindrical Roller Bearing

Theoretical research on the maximum contact stress of involute spur cylindrical gear pairs in the external meshing process

“…The reason is that the stress concentration induces the "edge effect" along the direction of tooth height when gears mesh at the tooth addendum. This type of stress concentration cannot be calculated by Herz formula, which is similar to the case that the "edge effect" of roller bearings cannot be calculated by Herz formula and can be solved by the finite element analysis [5]. Thus, the finite element analysis can reflect the stress concentration when spur cylinder gears mesh on the tooth addendums.…”

Dynamic Contact Characteristics of Elastic Composite Cylindrical Roller Bearing

“…Finite element simulation is widely used in bearing dynamic research as an important tool to analyze contact problem of some complex structures. Wei Yangang analyzes edge effect of hollow and solid cylindrical roller bearings during use, and proposes a new deep cavity hollow roller bearing [9] by using ANSYS software. Xu Hongyi establishes a multi-body dynamic contact finite element model of roller bearing, and calculates stress conditions [10] of low-speed bearings of different deformation constitutive relationship material model under two operating conditions by selecting two different plastic deformation models: bilinear isotropic model (BISO) and bilinear kinematic hardening model.…”
