The dynamics of continuously variable transmissions (CVT) is characterised by the discrete structure of the chain, which causes the polygonal action. Hence the mechanical model contains each chain link and pulley as a separate body. While a chain link is part of a strand, only joint forces act on the chain links, whereas, in the contact situation ...

Dynamic Stability of Chain Drives
Journal of Mechanisms, Transmissions, and Automation in Design, 1987The tension in power transmitting chains is subject to periodic fluctuation. This is brought about by factors such as polygonal action, eccentricity of sprockets, etc. A study of the dynamic stability of such a chain is presented. Instabilities due to polygonal action are investigated.

Bearing Friction Vs. Chain Friction for Chain Drives
Advanced Materials Research, 2013This paper studies experimental methods to measure friction, which determines the wear of chain elements in relative motion from a chain transmission, used in camshaft drives for an internal combustion engine. The paper presents a critical analysis of a constructive solution realized to determine the friction torque in parallel axes transmission ...

The invention relates to a device for deviating plate link chains, in particular in the deviation zone of a passenger transport installation, such as an escalator or a moving walkway. The individual plate links of the plate link chain are interconnected by means of bolts and bushes (6) which surround said bolts.

<div class="htmlview paragraph">TOOTHED and friction-gearing are said by the author to be the two distinct classes of power transmission between two shafts, and the silent chain he describes is in the toothed-gearing class according to his statement, since it has a fixed speed-ratio and causes a bearing pressure that varies almost directly with ...

Dynamics of High Speed Roller Chain Drives
Volume 3A: 15th Biennial Conference on Mechanical Vibration and Noise — Vibration of Nonlinear, Random, and Time-Varying Systems, 1995Abstract This paper deals with roller chain drives applied in combustion engines. In order to find characteristics for an optimal design, all components of a chain drive are taken into account. For a detailed analysis of the chain strand vibrations and the contact configurations each chain link, sprocket and guide is treated as a ...

Impact between chain roller and sprocket in a chain drive
Journal of the Franklin Institute, 1948Abstract This paper presents some analytical relations which may help in developing a better understanding of the mechanics of roller-sprocket impact. Various relative impact velocities are derived. These velocities may be used in impact energy relations for determining limiting sprocket speeds on the basis of roller breakage, noise, heating, and ...

Robust retail supply chains - the driving practices
International Journal of Advanced Operations Management, 2016A robust and responsive supply chain reflects the efforts put in by any company towards achieving strategy fit. This paper is an effort towards exploring and simulating the major driving practices of any supply chain in retail sector which can make it a robust supply chain. A set of variables (practices) have been identified from literature and through

Polygonal action in chain drives
Journal of the Franklin Institute, 1958Abstract The speed of a chain is subject to periodic fluctuations, even for a constant speed of the driving sprocket, due to the fact that a chain lying on a sprocket forms a polygon rather than a circle. It is shown that the dynamic loading of the chain due to this “polygonal action” is similar to that of a simple forced vibration where, beyond a ...
