The method of detecting linear displacement rotary encoder?！

:1, the use of "flexible coupling" spindle rotary encoder and linear displacement driving power plant direct coupling.
2, using a small gear (straight teeth, bevel or worm) box and power unit coupling.
3, for use on a straight rotating rack gear to transmit linear displacement information.
4, to obtain information on the linear displacement of the drive chain sprocket.
5, to obtain information on the linear displacement of the belt round belt.
6, using a roller equipped with magnetic rotary encoder to obtain displacement information (to avoid the slip) on a flat surface of the steel material linear displacement.
7, using a similar "steel tape" and "retractable wire assembly" Connect rotary encoder to detect linear displacement information (data processing shall overcome laminate winding error).
8, similar to 7, with the use of a small torque motor "retractable wire assembly" Connect rotary encoder to detect linear displacement information (currently in Germany similar products, complex structure, almost no stack winding error).
