Slew Bearing Conic, with Spacers, parametric Design with Fusion 360

thingiverse

This variation of my other Slew-Bearing has spacer-elements placed strategically between the rolls, which have a distinctive conic shape. The Fusion 360 model allows for precise control over the size of the spacers and the gap between each roll and its adjacent spacer. The ability to fine-tune this gap is crucial in achieving a perfect distribution of the rolls across the track. Notably, the outer trace is divided into two distinct halves. In contrast, my earlier design suffers from several limitations. For one, it's challenging to control the gap between the roll and the track, as well as the gap between adjacent rolls, due to the reliance on a single parameter. Additionally, controlling the bearing diameter proves difficult, as it's influenced by both the number of rolls and their individual diameters. The STL-files accompanying this project feature a bearing with 12 precisely positioned rolls (each with an 8 mm diameter at the center) and 2 mm spacers. To enhance 3D-printability, these spacers are split into upper and lower parts, yet they maintain identical shapes despite being exported separately.
