Drive Assemblies and Frame
Step 1: Build Drive Brackets
Parts Needed
REV-41-1303 – Bracket, Motion (4)
REV-41-1361 – Nut, Locking, M3 (8)
REV-41-1359 – Screw, Hex Cap, M3, 8mm (8)
Hint
Screw the nuts onto the screws just until it’s difficult to turn them; just so that the nuts don’t fall off. The screw heads will need to slide along the center of an extrusion in a later step.
Step 2: Build Motor Assemblies
Parts Needed:
REV-41-1300 – Core Hex Motor w/cables (2; do not plug cables into the motors yet)
Drive Bracket Assemblies (1 per motor, 2 total – use only two of the assemblies from step 1)
REV-41-1359 – Screw, Hex Cap, M3, 8mm (3 per motor, 6 total)
Note
Make sure that the brackets are facing the correct direction; the alignment ribs should be on the side away from the motor.
Note that motor directions are reversed – the power plug of the motor pictured on the left is on the bottom; the plug of the motor on the right is on the top.
Step 3: Build the Right and Left Rail
Parts Needed:
REV-41-1432 – Extrusion, 420mm, 90-90 degree (1 per side, 2 total)
Motor Assemblies (1 per side, 2 total – from step 2)
Drive Bracket assemblies (1 per side, 2 total –the two remaining from step 1)
REV-41-1327 – Shaft Collar (1 per side, 2 total)
REV-41-1326 – Bearing, Through Bore, Short (1 per side, 2 total)
REV-41-1347 – Shaft, 5mm Hex, 75mm (1 per side, 2 total)
Hint
Slide the head of the screws down the center of the extrusions.
The brackets should be flush with the end of the extrusions.
bracket, bearing, spacer, collar, two spacers, bracket with attached motor. (Order from the outside in.)
Step 4: Add Drive Wheels
Parts Needed:
Rail Assemblies (1 per side, 2 total – from step 3)
REV-41-1354 – Wheel, Traction 90mm (1 per side, 2 total)
REV-41-1327 – Shaft Collar (1 per side, 2 total)
REV-41-1324 – Spacer, 3mm (1 per side, 2 total)
Hint
Order from the outside in. (Collar, wheel, spacer, rail assembly.)
Make sure that the wheels do not rub the nuts. If they do, then revisit previous steps to make sure the construction is accurate.
Adjust axle length, so it is flush with the collar.
