Poly-V drives

Poly-V drives have power transmission capabilities up to 600 kW. This type of belt consists of a base material filled with “tensile members”. The belts are available in the following profiles: H, J, K, L, and M. The V-grooves of the belt fill up the V-grooves of the pulley and transmit the power by means of friction. Poly-V drives are almost free of vibrations and, as a result, produce hardly any noise. This drive can be fitted with inside and outside idlers. A transmission ratio of i = 40 is possible.
