Gilmer belt

Gilmer belt is a trade name for a type of belt used for transferring power between axles in a machine. The belt itself has ribs on the inner side to engage special pulleys mounted to the axles.[1]

Gilmer belts are often used in competition grade radio controlled cars (especially sedans), because they are lighter and have less rotating mass than a metal chain or a driveshaft system.[citation needed]

Gilmer belts are also very useful in full-scale automotive engines. Their precise pulley synchronization makes them a great candidate for valvetrain application, such as timing belts for driving the camshafts,[citation needed] an application pioneered by the 1954 Devin Cars which subsequently won the SCCA National Championship in 1956 (see May 1957 Sports Cars Illustrated article by O. C. Rich). Gilmer belts have also been used for driving critical components such as the external oil pumps in dry sump oiling systems used in high-performance engines.

Current manufacturers of automotive Gilmer Belt parts and accessories include Millerspeed, Continental, Goodyear, Moroso, Milodon, and others.[citation needed]

Some motorcycles use Gilmer belts instead of chain drive on the rear wheel.[citation needed]

Computer printers with moving print heads, including dot-matrix, inkjet, and thermal-transfer, commonly use Gilmer belts to control the motion of the print head(s).[citation needed]
