Polyamide worm gear : manufacturing and performance

The focus of this paper is to establish a characterisation method for seven polyamide (PA) grades to determine the major material to manufacture an automotive worm gear. The composite properties were measured according to the worm gear loadings: tensile strength, Young’s modulus, abrasion and impact...
