Consider actual problem of determine of limiting traction properties by friction curvedflexible driving belt in wedge belt drive applying to unlubricant drive mechanisms widely
used in various branch of machinebuilding, for example in technological automatic machine
as well as in various means of transport. The paper presents a new method graphic construction tractional friction dependence of curved elastic-extensible flexible bodies in the belt drive, which worked without lubricant with various coefficient of traction. Outlook in this papers a new simple and compact tribometer for measuring relative friction force of curved
flexible body with given it selves thickness and curve radius, it is can be easy applied in mechanical engineering industry. The paper also contents determine the analytical dependences of hauling characteristic of elastic belt drive and define a new universal friction constants of flexible wedge body, which completely coordinate to experience and exactly define bound of rational friction mechanisms design. Moreover, on base elasticdeformation model and analysis of tribodynamics of curved friction pair was find analytical solution for specified task of define limiting hauling ability of flexible mechanical transmission links, which used fir belt drive optimization synthesis in machine-building and flexible bodies theory improvement in machinery. As a result was stated rational sphere for operated wedge belt drive without full sliding in the machine transmission rotor drive systems. With the optimal traction characteristics of the belt drive designers can to select the proper construction for a specified design task according to the function of machine. For certain the study of the paper is very helpful for the designers to come up with the effective friction drive transmission more easily and quickly on the conceptual design of various unlubricant friction drive mechanisms.
