Automotive Differential with Hypoid Gearing, Motorized Model

thingiverse

https://youtu.be/xs2SApdWo20 The automotive differential is an ingenious mechanism that every automobile relies upon: it transmits power from the drive shaft at 90° to the driving wheels, while allowing them to rotate at different speeds when driving conditions demand it, such as during a turn. This is a motorized model of the most basic kind of automotive differential, known as the open differential. Unlike most 3D-printable differential models available, this one features a hypoid pinion/ring gear pair, not bevel. The model is powered by a 6V electric motor equipped with a speed reducer. It requires an external power source, such as four AA batteries in a holder or an old 6V phone charger with stripped wires.

Print Settings Printer Brand: MakerGear Printer: MakerGear M2 Rafts: No Supports: Yes Notes: The pinion needs sufficient support to ensure smooth meshing with the ring gear. We use Simplify3D and had to add support manually to cover all teeth, no other part requires support beyond the default amount. You must print 2 wheels, 2 side gears, 2 spider gears, and 1 of each remaining part. How I Designed This Tutorial: How to Model and Test the Automotive Differential in Blender We have created a tutorial on how to design the automotive differential in Blender 3D.

The Hypoid drive is similar to the bevel drive but the axes of the pinion and gear do not intersect.
