Gilmer belt is a trade name for a belt used for transferring power between axles in a machine. The Gilmer belt was originally sold by the L. H. Gilmer company in 1949,[1] and represents one of the earliest toothed belt designs. The belt uses trapezoidal teeth to engage matching grooves on toothed pulleys in order to maintain synchronicity between moving parts.[2]

The Gilmer name is still used by enthusiast circles, including automotive and RC hobbyists[citation needed]. However, the L. H. Gilmer Company became a wholly owned subsidiary of Uniroyal in 1940[3] and Uniroyal Power Transmission was purchased and absorbed by Gates Rubber Company in 1986.[4] Gates no longer sells belts under the Gilmer name.
