What Is the Straight Bevel Gear Cone Geometry & Mesh Forces Calculator?
Bevel gears transmit mechanical power between intersecting shafts, most commonly oriented at right angles (90° shaft angle).
Due to their conical pitch surfaces, gear teeth generate three-dimensional contact forces: tangential force Ft, radial force Fr, and axial thrust Fa.
This calculator determines pinion and gear pitch cone angles δ1 and δ2, cone distance R, mean pitch radius rm, and decomposes tooth load into all three force vectors.
