Design of a wolfrom cycloidal gearbox made with polymeric materials for mass production on smart construction yards

Object of this work is the design of a speed reducer which introduces two distinctive innovations: adoption of a Wolfrom layout and adoption of polymeric materials. This solution is innovative respect to current literature also for proposed application, concrete mixes and other machines for construction yards. In this work, features of proposed solution are critically compared with pre-existing ones demonstrating its potential industrial interest for applications constrained by cost limitations and exposition to severe environmental conditions. A preliminary design is then performed on benchmark case study also introducing finite element modelling of contact conditions of proposed polymeric gears. Results are quite promising and more generally adequate to demonstrate feasibility and potential utility of proposed solution.
