Differential Diagnosis of Spall versus Cracks in the Gear Tooth Fillet Region
This paper presents a technique to differentially diagnose two localized gear tooth faults: a spall and a crack in the gear tooth fillet region. These faults could have very different prognoses, but existing diagnostic techniques only indicate the presence of local tooth faults without being able to differentiate between a spall and a crack. The effects of spalls and cracks on the behavior/resp...
متن کاملDynamic Stress Concentration Factor in the Strip Plate with Fillet
Dynamic and static stress concentration factors ao, and as generated at a fillet part are observed by photoelastic method, and the comparison between two different factors is carried out. Next, the reflection coefficient A is calculated using the height of incident and reflected waves measured by the strain gauge. As the result, following relationship a= ( I+ A )as is derived experimentally. Th...
متن کاملSpur Gear Tooth Stress Analysis And Stress Reduction
Gears are commonly used for transmitting power. They develop high stress concentration at the root and the point of contact. The repeated stressing on the fillets causes the fatigue failure of gear tooth. The main objective of this study is to add different shaped holes to reduce stress concentration. A finite element model of Spur gear with a segment of three teeth is considered for analysis a...
متن کاملInfluence of Addendum Modification Factor on Root Stresses in Normal Contact Ratio Asymmetric Spur Gears
Tooth root crack is considered as one of the crucial causes of failure in the gearing system and it occurs at the tooth root due to an excessive bending stress developed in the root region. The modern power transmission gear drives demand high bending load capacity, increased contact load capacity, low weight, reduced noise and longer life. These subsequent conditions are satisfied by the aid o...
متن کاملIntercellular stress reconstitution from traction force data.
Cells migrate collectively during development, wound healing, and cancer metastasis. Recently, a method has been developed to recover intercellular stress in monolayers from measured traction forces upon the substrate. To calculate stress maps in two dimensions, the cell sheet was assumed to behave like an elastic material, and it remains unclear to what extent this assumption is valid. In this...
