Do you have a printable model for this?
Not at the moment but it should be possible to adapt the rack and pinion here.
It looks like intermitent motion based on the gear, but it isn't. What is the application?
do you have a buildable copy of this
Seems to be constant motion along length of travel. Therefore the switch between the slide's movement in one direction and the other would have to be instantaneous? Is this right?
Yes, the motion switch is instantaneous. Could be a problem with a real life mechanism, there would be a danger of the teeth snapping off.
i am so thankful ii found this
can the speed of this model be reduced??????
Great work rob, from the chaps of walbottle campus
Where did this wonderful mechanism originate?
I'm not sure, does anyone know? - RI
Hey guys im a robo nerd and im hoping to create a human like robot what sort of mechanisms could i use for the fingers??? i was thinking of using recipricating mechanisms
Try the quick return method found here:
Or you could now adapt the New Flip Face mechanism Variant
This motion was found in 'Climax' wind engines. The wind turned the pinion and the yoke moved vertically up and down, usually to pump water from wells for cattle in remote places.
Thanks a lot 4 the animations Rob; they helped us a lot to fully understand the concepts in mechanisms. Keep up the good work!!!!! From the Form 2C Design & Technology class of 2012 - Selepa Junior Secondary School ; Francistown - Botswana.
You are welcome! I am glad they were helpful - RI
this very good i love it
This is EXACTLY what I was looking for! I needed constant left-right motion utilizing only a simple rotary gear, and here it is!
i'm confused... why is the example there if it shows linear and rotary when the topic is reciprocating???
Reciprocating mean back and forth. You can have reciprocating linear motion as with the blue yoke on this animation - RI
Thank you so much. This would be absolutely perfect to adapt to a bicycle powered washing machine, which idealy needs to reverse direction so that the water and clothes in the drum sloshes one way then the other but the cyclist just keeps cycling one way. I was looking at all sorts of complicated mechanisms! This is so great.
wonderful and beautiful
Hi i wouldnt say i know next to anything about mechanisms so this question may seem simple and laughable but i was curious as how one who predict the total linear distance traveled that the mechanism would produce,
is it based on the diametor of the gear driving it or some other factor? ( ie bigger gear more distance )
the distance moved is related to the size of the gear. If the gear were to tune a full turn the distance would be the diameter of the gear times pi. In this example though, the teeth are only around roughly one third of the gear so the distance is the diameter of the gear, times pi, divided by three. - RI
do you have any examples ?
This looks similar in concept to #114 on 507 Mechanical Movements (http://507movements.com/mm_114.html)
