Rotary motion transfer not using gears.
Assembly consists of 13 components created with 3D printing, 11 bolts and 11 M3 nuts.
Parts are designed by the program FreeCad.
- Base 1 pc
- Crank 2 pcs
Printed with support
- CrankBearing 2 pcs
- PinBearing 2 pcs
For pins It is necessary to remove the strings that extend beyond the cylindrical shape. The Pin should move freely in the bearing opening. See Pic 1.
- Pivot 1 pc
This component can be printed verticaly or horizontaly. Horizontal printing causes the pivot and arms have printer strings perpendicular to each other and glide better. As with item (4), however, it is necessary to remove the strings that extend beyond the cylindrical cross section.
- PivotHolder 1 pc
- Shaft 2 pcs
- Arm 1 pc
- Arm1 1 pc
A. Between the Arms (8, 9) Insert the PinBearing (4), glue Arm (8) and Arm1 (9). Adhesive dot only on arm lock. The PinBearing must move freely in the Arms. The glued arms must slide freely on the Pivot.
B. On Pivot (5) put on glued Arms and one end of the pivot (5) Insert into the hole of the Base (1), the second to PivotHolder (6). PivotHolder screw to Base (1).
C. Insert Shaft (7) into the CrankBearing (3) and at the end of the Shaft (7) inset Crank (2). On the key dot adhesive to the key. Check that the Crank is safely connected to the shaft and rotates freely in the bearing. Do repeat for second CrankBearing.
D. Insert Crank pin into the PinBearing (3) and screw the assembled C-set to the Base (1). The same do with the second set of C.
The overall assembly of the angular gearing is on Pic 2.
