application. In typical mechanical transmission, the most widely used is the V-belt drive. V-belt of the cross section is isosceles trapezoid, V belt pulley also make the appropriate wheel slot. Transmission belt sheave and only two side contact, that is, with two side to face. According to the principle of the tank surface friction, in the same tension, V-belt drive lower belt drive and a greater friction. This is the V-belt drive performance major advantages. Plus V belt transmission allows the transmission of larger, pact, and V belt to standardization and the benefits of mass production, and the application of V-belt drive than flat belt drive more widely. Therefore, taking all these benefits with all sorts of V and the feasibility of actual operations, V-belt drive is the best choice.
