Variable Ratio Transmission
Variable Ratio Transmission
Zero-Max Inc’s new Variable Ratio Transmission, VRT™, dispenses seed and fertilizer with precision in agriculture equipment. Today’s precision farming equipment requires accurate and repeatable speed settings when dispensing seed and fertilizer. The new VRT infinitely variable ratio transmissions provide the vital operating link between advanced control systems such as GPS (global position systems) and the mechanical dispensing mechanisms used in precision seeding machinery. In the agricultural equipment, Zero-Max VRT infinitely variable ratio transmissions are used as the mechanical interface of the electronic controls and the seed metering mechanism. With all internal parts machined to strict and consistent tolerances, these transmissions ensure accurate seed dispensing for exact spacing over the entire cultivated field. Seed placement accuracy is maintained even when equipment ground speed varies. It provides the mechanical consistency and transmission accuracy enabling the equipment’s electronic controls to operate precisely in varying seeding conditions. Ruggedly designed to operate in the harshest environments, the VRT’s aluminium housing locks in mechanical drive components. The drives are pre-lubricated during assembly and completely enclosed in the heavy-duty housing. This maintenance free design ensures that internal parts are lubricated and free of contamination from outside debris.
