A study on the design of asymmetric gears for application in gear pumps

, 2020
This thesis presents a study on the design of spur gears with asymmetric teeth in external gear pump applications. A model is generated for asymmetric gears and for the specified gear pairs, Hertz contact stresses are determined by using analytical approach. The instantaneous flowrate equation is also derived.

Reduction of contact stresses using involute gears with asymmetric teeth [PDF]

Scientific Journal of Silesian University of Technology. Series Transport, 2015
Asymmetrical involute gears have a different value of the operating pressure angle for right and left side of the gear. These teeth are suitable for one direction of rotation. Such teeth enable to change the length of the generating line.

Novel Zwitterionic Polydopamine Nanofiller‐Reinforced Hybrid Membranes With Superior Antifouling Performance for Wastewater Treatment

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports one‐pot synthesized novel zwitterionic polydopamine‐silica (ZSiPDA) nanofillers for fabricating PES hybrid ultrafiltration membranes with enhanced hydrophilicity, permeability, and antifouling performance. The optimized membrane achieved over 91% humic acid removal and showed strong potential for municipal wastewater treatment.
