**Understanding Mechanical Connections: A Simple Guide**

In this video, I simplify the complex world of mechanical connections by introducing you to eight fundamental types: Cylindrical Press Fit, Conical Press Fit, Parallel Pin Joint, Cross Pin Joint, Keyseat Connection, Splined Connection, Polygon Connection, and Screw Connection. Through clear animations and easy-to-follow explanations, I’ll show you how each connection type works, their unique characteristics, and their applications in various machinery. Whether you're new to mechanical engineering or just need a refresher, this video will give you a solid foundation in understanding these essential components!

Okay this was quite interesting. Id like to see more

[Kids_Scissors]

I like that you specify what kinds of applications the assemblies have

[jet_enjoyer]

The last one is a “clamped connection” a screw connection refers to an externally threaded shaft mating to an internally threaded hub

[saberepee]

Especially important: with the pin connections for "medium torque", you can limit the torque of the system by the size and material of the pins!

Its like an electrical fuse for gears that can protect the life of your very expensive equipment all at the cost of occasional downtime and a few bars of tin!!!

[osmacar]

Press fit would slip att anything higher than low torque, the bolt assembled is the same. Hex can take medium, the keyed take high, so does the cross pin.

[lillyseider]

I have no idea why I'm watching this, but it's somehow super comforting even though I'm specialising basically in the opposite work field

[kxngbj]

I love these videos. Easy to understand even with such little time.

[atreyeuweaver]

the splined connection is similar to a PTO output on a tractor also it really makes since given the advantages

[Bald_Zeus]

Actually very applicable information for me as I need to choose one of these for a project.

[Jay-njrq]

Make it a star ⭐️
Better than a polygon and also aesthetic

[DumbAsh]

The screw connection is what drives my electric typewriters!

[matthewkent]

Spline shafts are very very common in ship’s propellor and reduction gearing shafts. They are very good at transmitting load and can withstand a lot of torque, but they also provide some leeway with axial loads and misalignments.

[goliathprojects]

Splined connections are your typical PTO's on tractors and other vehicles

[lernmor]

In the future, can you provide where we may find these connections in? Such as from blenders to cars to construction machinery?

Also, use your shorts as an ad for longer videos. It works on me at least!

[easterneurosweatsuitfan]

Am I the one who can't tell the difference between any of them visually?

[ronarthur]

Never seen the polygon connection before. What are the advantages over a keyed connection or a spline connection?

[kevin.]

How to create this animation?
Inside CAD software or other

[SuperS]

There's some hybrid versions. Ie. Conical hubs. Bit of a pain to align, but strong as hell.

[jojosthenewblack]

How do you know what each fit is suited for?

[calebm.]

Press fit is not suitable for high torque applications- and key/slot connections can be used for high torques depending on the size of the key.
