Our innovative rack and pinion drive system is perfect for larger format machines, 4' x 8', 5' x 10' and larger!
Now featuring optional 22 tooth motor pulleys for Nema 23 motors with 3/8" shafts, and 3/8" pivots for Joe's users for easy conversions.
These drives are designed to mount directly to one of our Extended Linear Carriages
riding on a horizontal cold rolled steel rail (must overhang 1530 or 3030 extrusion by 1/2").
Mount a 20 Degree Pressure Angle, 20 pitch rack to the extrusion underneath the rail using our innovative rack clamps -- combine lengths of rack to get the travel you want (rack clamps are sold separately).
Then just tap two of the existing carriage holes for a 3/8-16 bolt (or choose the "tapped hole option" for the carriages if you're uncomfortable doing this, and we can do it for you for a small fee). One hole serves as the pivot for the drive system, and the other as a connection point for a tension spring. Connect your drive, and get ready to rock!
The system provides a 3:1 belt reduction (2.73:1 with 22 tooth pulley), putting NEMA 23 stepper motors in an optimal range for speed and power. Watch the videos of the system in action below!
Note, the extended linear carriage shown in the video above is not included, and must be purchased separately.
Our R&P drives interface with 20 pitch, 20 degree pressure angle Gear Rack
, which we offer in convenient spliceable sections:
Simply mount rack to the extrusion underneath the rail using our innovative rack clamps
and combine lengths of rack to get the travel you desire.
