Abstract
In frame sawing machines, where a saw frame is driven by a crank mechanism, an inertial force produced by the saw frame cyclic motion significantly affects the machine foundation and also the saw frame driving system. This paper discusses the question how these serious using difficulties in machine performance can be eliminated. The authors present the principle of operation of the hybrid dynamically balanced saw frame driving system with the kinetic energy accumulator connected in parallel. The findings of numerical analysis are: this solution allows us to eliminate changing loads of the driving system and permits a reduction of the mass and dimensions of the machine, to eliminate a huge and expensive foundation, and to increase the working speed.
