WebCiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): This paper deals with the dynamics of continuously variable (CVT) chain drives. According to the … WebBased on the analysis model of polygonal action, by calculating a specific example, it is proved that the variable pitch characteristic of the new Hy-Vo chain is controllable. Through comparing the system center distance fluctuations for the new and the classical Hy-Vo chain, it is shown that both the system fluctuation difference and the system running …
Dynamics Of CVT Chain Drives: Mechanical Model And
Webchain when wrapped on a sprocket forms a polygon rather t h a n a circle, is known as polygonal action. One effect of polygonal action is to produce a periodic variation in. the velocity ratio of the drive, and if the frequency of this variation. coincides with a resonant frequency of the system, large stresses m a y. occur. WebFeb 18, 2024 · Abstract. This paper deals with the dynamics of continuously variable (CVT) chain drives. According to the discrete structure of the chain, which causes the polygonal actions, 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 including friction act on the chain links, … highland community college established
On Polygonal Action in Roller Chain Drives - ASME Digital Collection
WebJun 1, 2016 · In studies of string and roller chain drive dynamics it is often assumed that polygonal action leads to a parametric excitation described by time harmonic variation of … WebFeb 18, 2024 · Abstract. This paper deals with the dynamics of continuously variable (CVT) chain drives. According to the discrete structure of the chain, which causes the polygonal … WebPolygonal effect. The chain passes around the sprocket as a series of chordal-links. This action is similar to a non-slipping belt wrapped around a rotating polygon. For smooth operation of chain drives higher number of teeth 19 or 21 gives better life expectancy to the chain with less noise during operation. highland community college illinois president
