Torsen Differential Animation

After making the CAD model of the Torsen diff I had the idea to animate it. So I made 3 animations of it: - Complete ASM with turning forward, slip on right wheel and slip on left wheel - ASM of only gears with slip on the right wheel - Only one side of the gears while turning forward an having s...

I made my 2nd Animation of a Torsen differential.

These are some amazing animations guys.

There is a new animation showing a differential bevel gear set working:

Spherical conjugated Differential Bevel Gears

Here is a design family of a bevel gear set for application in differentials. The bevel gears are spherical conjugated which means that the gears are defined and limited by a spherical surface. The torque capatibility depends on the size of the sphere and the amount of pinion gears. So I made a v...

I will follow soon with a gear animation of a Schaeffler differential.

And here we go with the next one:

SCHAEFFLER Lightweight Differential - Animation

The series of animated differential mechanisms continues here with the planetary differential from Schaeffler. The slower wheel turns with 33,3% of the input speed and the faster wheel turns therefore 166,7% of the input speed.

And the next:

Planetary Differential - Animation

As a comparison to the Schaeffler differential you can take take a look at a conventional planetary differential. The ring gear is the speed input and the differential provides the the speed to the carrier and the sun which are connected to the wheels. The slower wheel (carrier) turns with 33,3% ...

They're just awesome, thanks!

Ok let me also get in. This is the first animation made with keyshot. These movement speed were calculated and rendered out.

Grundfos Gear Challenge

Input Speed: 985.52 rpm. Input Torque: 39e-3 Nm. Power Transmitted: 4.02 W. Output Speed: 1 rpm. Output Torque: ~19.5 Nm. Stages of Gear: 04. *** For more details visit documentation folder ( Grundfos Gear Challenge.pdf )*** Modeled in Catia v5; Rendered and Animated in Keyshot.

You're right, we can share the gearboxes animations from the challenge hiere ;-)

Grundfos Challenge - Dual Cycloidal Gearbox

This model represents my solution for the Grundfos Challenge. All necessary information can be found in the folder "documents" - Technical presentation - BOM - Section drawing - STEP model Searching for a compact high ratio gearbox I came up with the idea to use 2 cycloidal gearstages. In my opin...

need a animation of gear

Here is another one which shows the gear hobbing process:

Gear Hobbing of Helical Gear

Continuing my manufacturing series here is the hobbing process to cut a helical gear. This process was ivented by Hermann Pfauter who is known to be one of the pioneers for gear manufacturing. For the design of the hobbing tool I want to thank https://grabcad.com/constantin.stancescu for his amaz...

I hope you like it, too.

I'm working further and today I can present you some worm gear design and simulation:

ZA Worm with Globoid Gearwheel v02

Since I did my last model without consulting any values from professional literature, I didn't match the worm size very well. So here is a corrected version with common worm gear proportions. Technical data of the gearset: m=5mm z1=1 z2=41 x=0 dm1=40mm a=122,5mm
