Due to very force competition, all producer, not only manufacturers of gearboxes, have been forced to constantly improve their products. This has led to the harmonization of the technical characteristics of their gear units, even though they are not yet defined by the standard. Modern solutions of universal helical gearboxes are characterized, first of all, by large torque capacity and high values of gear ratio in the frame of relatively small overall dimensions of the gear unit. This paper provides an overview of common activities undertaken by manufacturers of universal helical gearbox to improve technical characteristics of their products.
