Scotch Yoke Mechanism Model

[@ttamaaleddungu2354]

It has been very very educative ,no theory required

[@oldguitarist-pl]

what's at the bottom of this tool which is attached to the wooden wheel? does it have small wheels at the bottom to slide on the table or bearings?

[@kenord3437]

A simple version of the old fashioned saw mill, well done

[@rowlandreeves5476]

Well done. Am going to use this for a project I am working on. Thank you for posting.

[@fourkings7897]

I have Master Degree in political science... But I'm intereted in physics and electeonics stuff... Right now I'm starting my on home school in physics and electronics. Your video is helpful and inspiring.. Thank you very much..

[@gonzo5648]

Great video, thanks for explaining! I found my way here trying to understand Alfadan's large displacement, inline four engine they are developing. Seems the traditional connecting rods have been replaced by some proprietary Scotch yoke. Paired up with the cylinder head being valveless, this engine sounds promising!

[@BlakeCreate]

Can anyone tell me how to calculate the force of the pushing rod given the Torque of the motor?

[@user-kr9bz1lq4u]

You can find out the force by Dividing the torque by the radius.

[@shreeshailpujari1429]

It is a very simple and good projects, I am very proud of you . This is Shreeshail Pujari.

[@vv8104]

Fcuk you Shreeshail Pujari

[@scose]

What is the point vs. a standard engine crankshaft mechanism? To avoid the sideways pulling force on the piston? But it is replaced with sliding friction between the pin and the slot.

[@kenord3437]

Another great device to build with the kids, thank you

[@Apollo-p1l]

Beautiful. Love your little models and mechanisms.

[@angelpuen8302]

Para aquellos que no tuvimos la oportunidad en la vida de realizar estudios respecto a este hermoso tema de la mecánica ,esto me parece una maravilla

[@hl5hl5]

Why is the wheel made so thick? I noticed the thickness in other models as well.

[@petep.2092]

To provide a good attachment for the pin, which would have a tendency to topple or bend a thin wheel.

[@Kapalek84]

Very nice device! Thank you for sharing!

[@superdau]

The motion of the piston here is exactly sinusoidal. Does anyone know how far off the motion would be from a sine with a tilting piston rod like all engines and compressors use? (well at least those that use a reciprocating piston)

[@radinelaj5716]

It can be applied on diesel and gasoline engines/vehicles

[@MrDaniyalAh]

Try sealing the cylinder side and adding valves to turn this into an air compressor

[@habibthebikershop4059]

Any info how this mechanism used in motor engines?

[@user-kr9bz1lq4u]

It works similarly to the slider crank mechanism converting linear mtion into rotational motion or vise versa.

[@hl5hl5]

Also I noticed you use plastic tubing over the cam rod. Do you have to do that? I have not seen that on wooden models.Thanks! This is the best video on making one!

[@petep.2092]

Probably to reduce wear on the surfaces sliding on each other. It may also reduce the clicking noise when the pin breaks contact with one side of the cam rod and makes contact with the other side when changing the direction of the linear movement.

[@toniturnwald9890]

Pretty nice work and also a pretty good show and tell. Bye bye Toni

[@riazhassan6570]

Sliding friction at four points. What is the advantage of this set-up over an ordinary crank mechanism?

[@petep.2092]

1. No movement/inertia of the linear moving parts in any other direction, so less stress when reversing direction. 2. The linear output is purely sinusoidal-the piston exactly follows the pin on the wheel, whereas with a crank the distance between the pin rotating on the wheel and the piston varies due to the varying angle of the connecting rod (from 0° when the pin/piston is at TDC & BDC up to a maximum angle at 90° away). This results in a lower linear acceleration of the piston when moving away from TDC/BDC until mid-stroke, and then higher acceleration from mid-stroke until the end of the stroke (the higher and lower being relative to the acceleration of the pin on the rotating wheel in that direction). Thus a crank distorts the linear motion output so it is not purely sinusoidal. The shorter the connecting rod relative to the offset of the crank (i.e. the wheel radius) the more the distortion.

[@BwIAVamsi]

Can i get this dimensions

[@melindarisnufebriana3121]

cool, but what type of motor dc that you use? please i need that specification

[@almosteverything3982]

It is just regular moter but its powered by power moter machine, also pls sub to my channel, i hope this help

[@user-kr9bz1lq4u]

@@almosteverything3982 Any motor works

[@prathapprathu7609]

How to make this will you please explain

[@amanlogg]

Yes it is good but, What is the specification of the motor used in the project

[@user-kr9bz1lq4u]

It's a motor with a gear reduction. IF you mean what type of motor idk. But any motor should work just fine if you want to make a scotch yoke yourself.

[@janszenable]

Wauw, simple and elegant. Thank you.

[@udayaranawaka1235]

Cool video, appreciate about your creation.

[@meminyakyashirokof9615]

Manuel Rodriguez Achac in English? xD please share the blueprint of this proyect please

[@mohammadjohary]

Yes I have found it interesting 👍thank you very much

[@lauram.garzon396]

Great video!

[@muhammadsyafiq1991]

I can see how it is great for rotary to linear motion, but how about the opposite (linear to rotary)?

[@tntmaps4542]

It’s just a motor that goes one way because there is no motor driver so it can not go the other way

[@petep.2092]

Like a reciprocating engine, it would require a flywheel for momentum so it wouldn't get stuck at top dead center or bottom dead center. Would also require initial rotary motion applied to the wheel when starting, as linear force applied when the rotating pin is at TDC or BDC would present a simple shear force on the pin and would not cause it to rotate. Alternatively, a second piston/cylinder arrangement in parallel operation but offset so both pistons are not at TDC or BDC at the same time.

[@Manila-wo3pi]

Nice, thanks for sharing !

[@MuerongLykaMae]

type of motor???

[@user-kr9bz1lq4u]

Any type of motor should work although this one has a gear reduction which I don't think matters too much.

[@alibirahwi8071]

I like this project .. good job

[@ludicscience]

Thanks

[@NerdZEY]

🤨

[@anonymousinc6330]

Nice setup... Gives me some ideas for a project I'm brainstorming.

[@ovalwingnut]

Lovely mechanical action to watch. No, BEHOLD!! 👍😎

[@sierraecho884]

The scotch yoke is not found in regular combustion engines. There is only one from the 1940´s which was never build because it had all sorts of problems, but no modern engine uses this mechanism.

[@user-kr9bz1lq4u]

Even if it were The Scotch Yoke mechanism has disadvantages with the most major disadvantage being the constant sliding of the bearing in the rectangle slider causing wear and tear from the friction.

[@charleshudner4149]

Esse sistema numa roda d'água numa bomba com 2 pistões , é muito eficiente!

[@shed.projects5150]

Loved it, thanks.

[@eduardopena3387]

Amigo yo sigo tu canal en español jajajajaja cuando ví este video me sorprendió por qué dije, esa voz me parece demasiado familiar

[@MedSou]

*Awesome,Thank you* 👍👍👍👍

[@dennisseeker36]

thanks for sharing

[@TechsScience]

Why don't you use for purpose? E.g. you can make Air pump or something

[@ludicscience]

Tjat will be nice

[@MohitSagar]

good model...

[@azisazlin7649]

Hi, i'm from Indonesia

[@boyanatanassov9263]

Ingenious!!!

[@rajukhunti329]

Price?

[@user-kr9bz1lq4u]

There is no price.

[@honeyb3603]

i want linear to rotational motion, not rotational to linear. linear must be driving the rotational output

[@user-kr9bz1lq4u]

The motion is converted into another motion one way or another. If you have plans to build one yourself do as you wish.

[@anandkudoli1799]

very nice video thanks sir

Saudações LS Ludic Science. Saudações a todos. Mecanismos simples e curioso. Converte o movimento circular em linear no embolo. O oposto também é possível. Realmente interessante. Tudo de bom.

[@electromagic3111]

Nice and brilliant like

Nice show other side allso like time of front side.

[@Mr_c-tm3hu]

First! and great mechanism

[@fetB]

i've seen this before.

[@vkvk2137]

Your email pls ..

[@poweredbysergey]

Cool

[@raymondo162]

that's only HALF the mechanism.............. perhaps best to google before building

[@user-kr9bz1lq4u]

how the hell is this only half the mechanism? The scotch yoke needs no other parts.

[@voytec777]

Dobra baza do wykonania pieprzącej maszyny...
