Characteristic application areas of three-stage gear unit with larger torque capacity ( and with smaller torque capacity, but higher gear ratio (. Shaded area represents less expensive solution. Some large manufacturers are trying to cr eate so-called intermediate size of gear units and thus offer cheaper solution (Figure 6, Table . With this additional size, they increase the number of gear unit components they must produce (housings, gears, shafts, bearings, etc.), so this procedure can not be considered as favourable as the application of housing with two sets of gear pairs.
