In today’s cars push belts (steel or hybrid) have most common use, but in small vehicles like scooters or snowmobiles the powertrain is based on rubber V-belt. The most important disadvantage of rubber belt drive is relatively low transmission efficiency, which does not exceed 70% or sometimes 80% in special conditions. The belt vibration phenomena is one of the reasons of power losses. The experimental research with the use of high-speed camera allowed determining the ranges of amplitudes and frequencies spectra of belts vibrations in various operating conditions. The obtained results are important for theoretical analysis of rubber belt drive efficiency.
