Individual Python-Drive CV drive shaftsPicture left: Drawing of the original design of the first CV joint (constant velocity joint) by Alfred Rzeppa from1927. On basis of this drawing the CV joint was patented.
Python-Drive CV drive shafts operate in the same way; they have no torsional or inertial excitations inherent in cardan style drive shafts. The smooth torque transmitted from a Python-Drive CV drive shaft occurs even when the operating angles are unequal. The Python-Drive CV drive shaft will successfully accomodate unequal angles better than any other coupling device.
Python-Drive constant velocity drive shafts may be used to a maximum angle of 8º (8º per CV-side). The maximum prop shaft rpm. may be 4500 rpm. (depending on model).For more detailed information, please refer to the installation manual. Python-Drive CV-drive shafts are also available in custom lengths.
