When high torque outputs are required with high accuracy then a precision gearhead is the most effective answer. A planetary gear mechanism provides a high gear ratio in a compact package with good torque capacity. Careful design and manufacture also allows high precision with low backlash. These characteristics make planetary gearheads ideal for precision linear motion.
Matching a servo motor to a precision gearhead is an excellent way of increasing the torque output and running a higher inertia load. Note as a design guide it is better to design a precision drive around the torque and inertia loading rather than a speed requirement. As a servo provides a consistent torque output across a wide speed range, output speed is usually of a lesser concern than torque or inertia matching.
Tecnoingranaggi Riduttori have been a specialised manufacturer of precision gearheads since 1988. They focus exclusively on high quality planetary gearheads and now manufacture more than 40,000 units per year. They make extensive use of NC machining and robotics to provide high accuracy products to ISO9000 standard. Production has become so mechanised that IAS can now offer a 3 day (+shipping) ex works express service for inline gearheads.
