The Test of Roots Blower Lobes Profile
thingiverse
I tried to get the profile by cam design method, but failed. So the profile of these fan lobes is still derived from the cycloidal curves. Dimensions : 58 * 60 * 17 mm^3 Module:1.667, 2, 1.5 mm Number of gear teeth: 18, 15, 20 Contact plane clearance: 0.2 - 0.6 mm 本來想用凸輪設計法得到輪廓，但失敗了。 所以這些扇葉的輪廓仍是用擺線曲線推導而得的。 尺寸：58 * 60 * 17 mm^3 模數：1.667、2、1.5 mm 齒數：18、15、20 接觸面間隙：0.2 - 0.6 mm Youtube: https://youtu.be/c_zy5nG-bT4
