GEOMETRICAL STUDY OF GUIDE-CHAIN CONTACT, FOR GENERAL CHAIN TRANSMISSION

The friction complexity between guide and chain is generated by a large number of factors acting simultaneously, of which wear has a significant share. During transmission functioning, guide and chain are subjected to normal forces in their contact surfaces. An analysis of the guide position can be described by a mathematical model. This paper presents a synthesis on the geometry of the contact between a guide and chain drive transmission. In the first part of the paper are established mathematical relationships underlying the extent of chain drives with a chain guide. Then, based on the mathematical model are traced a number of variation diagrams of geometric and kinematic parameters.
