TRIBOMECHANICAL SYSTEMS IN TIMING BELT DRIVES

Abstract

Timing belt drive, as relatively new concept in power transmission, uses the lithe element (timing belt) for realisation of its basic function. Kinematics of coupling between the timing belt drives and trapezoidal teeth profiles is explained in detail in the paper. Combining of chain, toothed and belt transmissions has brought a series of different motions, in tangential, radial and axial directions, especially in the period when the belt and the belt pulley enter the coupling. Identification of main tribomechanical systems and their detailed analysis are conducted based on kinematic analyses.
