Use of alternate material is always a continuous development in any industry. Such proposals aim at weight reduction, improve life of the components and reduce the components cost. When it comes to the compressor application, there is always a challenge in replacing such parts with polymers, especially on the canopy parts. This study aims at replacing the material of screw compressor canopy with a suitable material with the target of weight and cost reduction, without compromising the functional requirements. Suitable material for the shroud assembly is chosen using the theoretical method and validated using finite element analysis. Suitable process is chosen for the Proto-type shroud from the proposed alternate material (HDPE) and tested in the real-time environment

As lined, higher transmission ratio drives system will have uneven stresses in the root region of the pinion and wheel. To enrich this agility of uneven stresses in normal-contact ratio (NCR) gearing system, an enhanced system is desirable to be industrialized. To attain this objective, it is proposed to put on the idea of modifying the correction factor in such a manner that the bending strength of the gearing system is improved. In this work, the correction factor is modified in such a way that the stress in the root region is equalized between the pinion and wheel. This equalization of stresses is carried out by providing a correction factor in three circumstances: in pinion; wheel and both the pinion and the wheel. Henceforth performances of this S+, S0 and S- drives are evaluated in finite element analysis (FEA) and compared for balanced root stresses in parallel shaft spur gearing systems. It is seen that the outcomes gained from the modified drive have enhanced performance than the standard drive.
