Short[edit]

The article about cams is much too short. -Unsigned/Undated

this article is sad[edit]

it's much too short. i agree with the last person who started this discussion. and i need to base a whole research paper on this too! No picture either :( Davidbod 00:51, 28 May 2006 (UTC)

  • Added in a nice animation from the camshaft article, makes it a bit better. 209.47.162.98 14:48, 22 August 2006 (UTC)
It should use simple diagrams to show how it works.
Why does the "prime circle" reference point to a rock band? Was a dis-ambiguity link removed?

"The reason the cam acts as a lever is because the hole is not directly in the centre, therefore moving the cam rather than just spinning." It's a vague statement - I have observed many cams rotating in machines with a hole in centre. Altaf —Preceding unsigned comment added by 203.81.231.159 (talk) 06:31, 20 March 2009 (UTC)

Redux[edit]

This article was written so poorly I can't tell the difference between vandalism and poor writing/a poor attempt to explain what the purpose of cam lobes are...this article IS sad —Preceding unsigned comment added by 67.246.13.226 (talk) 02:05, 1 June 2009 (UTC)

Actually, one just needed to look at the history to see what the vandalism edit shortly before yours had overwritten (ie, most of the lede). The article wasn't quite as sad as you thought. I reverted to the pre-vandal version. Cheers, — ¾-10 05:18, 1 June 2009 (UTC)

Definition[edit]

Brushed up definition; it was way too hard to understand properly eg by people without engineering skills. Now it states:

A cam is a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion or vice versa. [1][2] It is often a part of a rotating wheel (eg. an eccentric wheel) or shaft (eg a cylinder with an irregular shape) that strikes a lever at one or more points on its circular path. —Preceding unsigned comment added by 91.176.221.125 (talk) 09:41, 13 September 2009 (UTC)

Image[edit]

Rotary to linear motion conversion crank.jpg

Added this [first] image. Needs CGI'ing dough.

I've removed this image, because it does not depict a cam, but rather an eccentric. I watched the source you listed on the image and I heard them refer to the eccentric as a cam, which is just incorrect. Wizard191 (talk) 19:50, 13 September 2009 (UTC)
I agree. The first image appears to be a complicated slider crank, not a cam nor an eccentric. - AndrewDressel (talk) 19:31, 20 September 2009 (UTC)
Changed my original picture and uploaded it at eccentric page. Added this [second] image instead. - 91.176.222.111 (talk) 16:29, 20 September 2009 (UTC)
The second image, Rotary to linear motion conversion cam 1.jpg (replaced with a dupe on commons so name is changed --MGA73 (talk) 08:11, 4 October 2009 (UTC)), looks like a crank, as in crankshaft, to me. -AndrewDressel (talk) 18:49, 20 September 2009 (UTC)
Andrew, you are quite right, that is not a cam, but rather a crank. Wizard191 (talk) 18:16, 21 September 2009 (UTC)
Thanks for the correction, changed the images

new reference[edit]

When i get some time, I'd like to add a displacement diagram to the article. This handbook should be referenced in this article: C. H. Moon, Cam design, a manual for engineers designers and draftsmen, AMCAM, 1961 ---BAxelrod (talk) 01:58, 9 July 2010 (UTC)

cam pulley[edit]

Can we talk about this concept? It's what the nautilus cam used I think. DB (talk) 01:13, 28 April 2011 (UTC)
