Song is based on a Dr. Seuss story called "The Sneetches". I copied the following from Wikipedia:

"The story tells of a group of creatures called Sneetches, some of whom have a green star on their bellies. At the beginning of the story, Sneetches with stars discriminate against and shun those without. A "fix-it-up chappie" named Sylvester McMonkey McBean appears and offers the Sneetches without stars the chance to have them with his Star-On machine, for three dollars. The treatment is instantly popular, but this upsets the original star-bellied Sneetches, as they are in danger of losing their special status. McBean then tells them about his Star-Off machine, costing ten dollars, and the Sneetches who originally had stars happily pay the money to have them removed in order to remain special. However, McBean does not share the prejudices of the Sneetches, and allows the recently starred Sneetches through this machine as well. Ultimately this escalates, with the Sneetches running from one machine to the next.

'The Sneetches' was intended by Seuss as a satire of discrimination between races and cultures, and was specifically inspired by his opposition to antisemitism."

Gear, Cam and Cog are all parts of the machine. They are common parts in factories.

"She's a gear, you're a cam, I'm a cog This machine was invented by McBean But we all make up the parts"
