Boîte de vitesses montée sur arbre

Généraux：

The shaft mounted boîte de vitesses reducer provides a very convenient way to reduce the speed, it can be directly fixed on the drive shaft instead of requiring foundations of its own. De cette façon, one or two elastic couplings and the internal belt tensioning device can be saved. The screw buckle on the torque arm can adjust the belt elasticity conveniently and quickly.
