These POSIPLAN gear reducers, which are protected by a specific patent, feature a combination of planetary and helical gears that takes advantage of the strengths of each technology: compact size, high reliability and easy maintenance. The PH series of planetary helical gearboxes combines one slow helical stage with one or more planetary stages. The design of these compact gear units is based upon precise analyses using FEM techniques, which means performance, duration and silence. These lighter, more compact gear reducers surpass traditional solutions, ensuring shorter production times and lower production costs.
