To study the variation rules of nonlinear stiffness double-row angular contact ball bearings (DR-ACBB), this paper proposed a general mathematic model for DR-ACBB under three different configurations based on improved quasi-static bearings, an explicit expression matrix is analytically derived, and double-layer nested iterative algorithm Newton–Raphson method designed to realize efficient solution model. Then, effects preload, speeds, loads variations arrangements are comparatively analyzed....
Plant immune receptors belonging to the receptor-like protein (RLP) family contain extracellular leucine-rich repeats (LRRs) and a short cytoplasmic tail linked by single transmembrane motif. Here, we report identification of snc2-1D (for suppressor npr1-1, constitutive 2), semidominant Arabidopsis thaliana mutant with constitutively activated defense responses. Map-based cloning showed that it encodes an RLP. The point mutation in leads substitution second Gly for Arg conserved GXXXG motif...
Skidding is a typical behavior of high-speed angular contact ball bearings. Studies show that the effect preload on bearing skidding and thermal characteristic essential but insufficient. This paper proposed comprehensive mathematic model to predict bearing, influences interactions between raceways, cage lubricant have been taken into consideration. Based model, heating generation was calculated effects temperature rise were analyzed. For validation proposes, hydraulic variable experimental...
Abstract The vibration induced by the varying compliance (VC) or stiffness fluctuation of ball bearing plays a key role in dynamic performance rotor system. aim this article is to study behaviors under different operating conditions. This presents an improved mathematic model for with wider applicability based on new initial/reference position assumption and ball-raceway contact/separation determination. proposed not only gets rid limitations raceway control hypothesis but also considers...
Abstract Flightless I (Fli I) is an evolutionarily conserved member of the gelsolin family, containing actin-binding and severing activity in vitro. The physiological function Fli during animal development remains largely undefined. In this study, we reveal a key role Caenorhabditis elegans homolog, fli-1, specifying asymmetric cell division establishing anterior–posterior polarity zygote. fli-1 gene also regulates cytokinesis somatic cells germline interacts with phosphoinositol-signaling...
The flexible bearing is usually connected to the cam with an interference fit in harmonic reducers. Studies show that can cause changes structural parameters of and lead service performance its supporting system. This paper proposes a general simulation method investigate influence reducers concept equivalent for non-circular between cam. Then, four steps based on sequential assembling loading process are designed ensure assembly concentricity convergence. analysis results indicate...
