'Chain Ring' in Solidworks

Crafting a Chain Ring in SolidWorks requires a clear understanding of its design components and functionality. Start by opening SolidWorks and creating a new part file. Set the units to millimeters for precision, then create a sketch on the XY plane using the rectangle tool. The dimensions should be 50 mm x 15 mm, which will serve as the foundation for the chain ring's base. Next, extrude this sketch upwards by 5 mm to form the initial shape of the chain ring. Then, create another sketch on the XY plane with a diameter of 200 mm, which represents the chainring's outer edge. Subsequently, use the "Offset" feature in SolidWorks to subtract the previously created rectangle from the larger circle, thereby generating the gap between the teeth. The offset distance should be set to 3 mm for proper spacing. Now, create a new sketch on the XY plane that includes the initial chainring shape and the gap created by the offset operation. Utilize the "Split" feature in SolidWorks to divide this combined sketch into two sections: one representing the teeth of the chainring and the other representing the spaces between them. Apply the "Revolve" feature to these two separate sketches, with the axis aligned to the Z-axis for proper orientation. The first section will form the teeth, while the second section will generate the gaps. To complete the design, merge the resulting revolved parts into a single component, ensuring that they are correctly positioned and oriented. Finally, use the "Mirror" feature in SolidWorks to create a mirrored copy of the chainring on the opposite side, which will serve as the drive side. By following these steps, you can successfully create a functional chain ring in SolidWorks, suitable for simulation or 3D printing.
