Design and manufacture of cycloid reduction gearbox made by combined materials for working in corrosive environment

Abstract

This paper presents research result of design and manufacture of the cycloidal gearbox with some advantages such as low noise, high transmission ratio, high load, and erosive resistance. The new point of this works is the utilization of combined stainless materials that can be worked in an erosive environment, especially in the aquatic mechanical area, in order to save material and to increase the cycle life of this equipment. Besides, the cycloidal gearbox with stainless steel and polymer materials can be lubricated by water and is used with water-resistant or submersible electric motor. This new cycloidal gearbox can replacethe worm gearbox. A 1,5 HP cycloidal gearbox with the reduction ratio 29 that is used in aquaculture has been designed and manufactured successfully. In this work, the analytical method and numerical simulation are used to design and manufacture the gearbox. For the future works, this cycloidal gearbox will be tested in the real environment with aquaculture aerator system so that its performance will be fully verified and assessed
