Herringbone Pinion Assembly for Linear Encoder

Herringbone Pinion Assembly for Linear Encoder 3d printed Mechanical parts Robotics
This herringbone bone gear assembly, combined with the rack, magnetic mount, shaft, rotary encoder and arduino (all in the links below), can be used as a poor man's linear encoder. The gear has a 12.1275 mm pitch radius (2.999 in circumference) and the mount is designed to hold a 1024 P/R, quadrature rotary encoder. The housing has space for two standard skate board bearings (22mm OD, 8mm ID, 7mm width) and there is also room for two 1/2" diameter, 1/8" thickness rare earth magnets to hold the rack firmly against the pinion (you have to mount the rack on a piece of 1"x1/8' steel of course). The housing is is attached to the magnetic base using a standard 5/16 NC bolt.
