Abstract: The property of the mechanisms with rolling levers is the using of higher kinematic pairs, usually it have slipping. With selecting of profiles of elements of the higher pair  centroids in absolute motion or relative motion can be achieved absence of sliding friction, it is increase the durability and efficiency of the whole mechanism. The article is devoted to the power analysis of mechanism with rolling lever, in contrast to known designs, is made with two higher kinematic pairs. Reactions in kinematic pairs were determined considering the friction forces in the higher pairs using the method of kinetostatics. Special point was found, it solve the equations of equilibrium of threelink group with zero mobility. The friction forces were produced using the method of successive approximations, that is, taking a first approximation, the absence of sliding friction (pure rolling), reaction in the kinematic pairs were calculated, the frictional force was determined and was offered in the equations of equilibrium, updating the desired reaction. The cycle is repeated until the required degree of accuracy of values. The balancing moment was detected on the drive link, it is necessary for the selection of the engine. Thus we have proved of the full kinetostatic solvability of the mechanism with the rolling lever.

Key words: higher kinematic pair slipрing reaction force of friction balancing moment
