Polymers in gearbox production

Abstract

Technological progress spurs the creation of new machine designs, the development of new highly advanced technologies, as well as the introduction of new materials, including polymeric ones, that meet the economic and ecological criteria. An analysis of the literature reveals that there are few works outlining the rules for the design of machine components using polymeric materials, including composites and nanocomposites. This article is a review of the literature on the use of polymer matrix thermoplastic composites (PA6 -polyamide 6, PA66 -polyamide 66 and POM -polyoxymethylene) in toothed transmission systems. The presented examples demonstrate the production of hybrid polymer nanocomposites with addition of inorganic fillers and their application in the manufacture of machine components, including gears.

Possibilities of Using Selected Additive Methods for the Production of Polymer Harmonic Drive Prototypes

“…The relocation is in the opposite direction to the defined torque direction. The displacement of the area of cooperation of the harmonic drive, relative to its main axes, is known from the literature [2,3,37,38], and numerical calculations have confirmed this feature. However, the displacement of this area is not significant, because the stresses that occur in the flexspline are mainly the result of its deformation.…”

An Injecting Molding Method for Forming the HFRP/PA6 Composite Parts

“…In practical applications, CFRP often needs to be joined with other materials to form functionally enhanced components [ 8 , 9 ]. Polyamide-6 (PA6) is a kind of nylon material with good wear resistance and self-lubricating properties, which is widely used in automobile parts, electronic equipment and packaging materials [ 10 ]. For the excellent properties of HFRP and PA6, the composite parts made of these two materials have been widely used in the lightweight design of automobiles [ 11 ].…”
