APPLICABILITY OF CONVEX AND CONCAVE SHAPED SURFACE TEXTURING TO IMPROVE DAMPING PERFORMANCE OF MECHANICAL TENSIONER FOR TIMING CHAIN OF INTERNAL COMBUSTION ENGINE

Applicability of Convex and Concave Shaped Surface Texturing to Improve Damping Performance of Mechanical Tensioner for Timing Chain of Internal Combustion Engine

The present study describes an improvement of damping performance of a mechanical tensioner driven by friction force at the power spring interface, used for the timing chain system for an internal combustion engine.The mechanical tensioner consists of a power spring subjected to face-to-face contact with a reciprocal motion and a leaf spring to app

The Upper Miocene of the Rostov Dome (Eastern Paratethys): Implication of the chronostratigraphy and bivalvia-based biostratigraphy

The Rostov Dome is located in the south of the Russian Platform.In the Late Miocene this area was embraced by the Eastern Paratethys.The implications of a recently developed Neogene chronostratigraphy to the studied area are discussed.The Sarmatian regional stage corresponds to the upper part of the Langhian, the entire Serravalian and the lower pa
