A Harbinger of Spring

Winter may finally be coming to a close – the planetary gear arrived. After an 8 week gestation, a beautiful piece of machined steel has arrived. It takes a 0.5-inch input shaft and has the same diameter output shaft, the better to replace the coupling and to serve as a half-axle for the drive wheel. In the input end you can see the coupling, safely hidden within the housing. On the output end, there is enough shaft to engage the Trantorque Mini inside the drive wheel. Some machinist adjustments will be made and then it will take its place within the azimuth drive.

Its motion is smooth and it drives and back drives effortlessly. With Spring comes the sound of the machine shop!
