Sometimes we can see a picture of three gears stuck together, and some social friends complain about it. The person who drew the picture must not be a mechanical student. If they are put together like this, the gears will not turn at all.
Can the 3 gears turn together? Those of us who work in machinery should all know that it will definitely not be able to rotate on a flat surface, why it cannot be rotated, and how to rotate it, this video will explain it clearly to you.
Do you feel your brain opening? Let's take a look at a wave of unusual gear combinations:
Each gear (screw) has only one tooth, and the width of the gear end face must be greater than the distance between the gear shafts.
3. 4 small gears coaxial and reverse rotation
This mechanism was used instead of a 3-bevel gear transmission to avoid the use of a vertical shaft.
4. Gear coupling 1
Internal gears have no bearings.
5. Gear coupling 2
Internal gears have no bearings.
6. Internal and external gears
7. Gear reducer with equal number of teeth
This is a result generally considered impossible to achieve.
8. Helical gear drive 1
Auxiliary external screw drive.
9. Helical gear drive 2
Auxiliary internal screw drive.
10. Helical gear drive 3
