Abstract:

A literature survey was performed in order to determine the plastic materials and design techniques used in gear applications, with evaluation as to feasibility for use in military items. The main plastic gear materials are acetal, nylon, polycarbonate, modified polystyrene, and filled phenolic. The advantages in their use are numerous however there are some limitations which must be considered in designing with plastics. Full knowledge of the properties of the contemplated material as related to the intended gear environment must be known. Plastic gear materials are suitable for ammunition items, with the specific material selection controlled by the functional and environmental conditions imposed by the item. Testing of prototypes is required in making proper evaluation of plastic gears. Two case studies have been provided as examples one to show where plastic gears are feasible and the other to indicate an application where the design limits the use of plastic materials. Author
