Özet

This paper introduces an original, fully compliant universal joint design. Many mechanisms with different dimensions are investigated. The proposed design is a single-piece compliant mechanism. The number of flexible segments is a design parameter determined as a function of transferred torque. The mechanism can be produced by additive manufacturing from polylactic acid and polypropylene. It is possible to produce the proposed design as a single piece of polypropylene by additive manufacturing and injection molding methods; thus, it has the advantage of ease in manufacturing. The proposed design's bending and torque transmission capacities are determined by applying analytical and numerical methods. Furthermore, a prototype was manufactured, and experiments were conducted. It is verified that the results of the experiments are consistent with theoretical approaches. The proposed fully compliant universal joint design has a great potential in the industry.
