The method to detect linear displacement by rotary encoder

Answer: 1, the use of "elastic axis" rotary encoder to drive linear displacement of the power unit of the main shaft coupling directly.

2, using a small gear (straight tooth, umbrella gear or worm gear and worm) box and power unit coupling.

3, use on a straight rack straight line displacement message by turning gear.

4, in the drive chain sprocket for linear displacement information.

5, the synchronous belt wheel synchronous information with linear displacement.

6, use the installation of magnetic rotary encoder wheel on the surface of the flat steel material that linear displacement displacement information (avoid slip).

7, use a similar "steel tape" "can bounce back wire assembly connection of rotary encoder to detect linear displacement information (data processing must overcome laminated winding error).

8, similar to 7, with a small torque motor "can bounce back wire assembly connection of rotary encoder to detect linear displacement information (with Germany have similar products, the structure is complex, almost no laminated winding error)
