V Belt History from automotivedrivingbelt

Trade journal coverage of V Belt in automobiles from 1916 mentioned leather as the belt material,and mentioned that the V angle was not yet well standardized.The endless rubber V-belt was developed in 1917 by John Gates of the Gates Rubber Company. Multiple-V-belt drive was first arranged a few years later by Walter Geist of the Allis-Chalmers corporation, who was inspired to replace the single rope of multi-groove-sheave rope drives with multiple V-belts running parallel. Geist filed for a patent in 1925 and Allis-Chalmers began marketing the drive under the "Texrope" brand; the patent was granted in 1928 (U.S. Patent 1,662,511). The "Texrope" brand still exists, although it has changed ownership and no longer refers to multiple-V-belt drive alone.

A ribbed belt is a power transmission belt featuring lengthwise grooves. It operates from contact between the ribs of the belt and the grooves in the pulley. Its single-piece structure is reported to offer an even distribution of tension across the width of the pulley where the belt is in contact, a power range up to 600 kW, a high speed ratio, serpentine drives (possibility to drive off the back of the belt), long life, stability and homogeneity of the drive tension, and reduced vibration. The ribbed belt may be fitted on various applications : compressors, fitness bikes, agricultural machinery, food mixers, Timing Belt Manufacturers washing machines, lawn mowers, etc.
