Abstract. Oldham's coupling is a really interesting device. It is possible to understand the method with a knowledge of only junior high-school geometry. Compressors in air conditioners also use this idea, where involute curves are used for the teeth of the cogs in the compressor. Mathematics doesn't just reside in textbooks; it's alive in our daily lives.
