Abstract

External gear pumps (EGP) have become more and more common in a variety of industrial fields because of their advantageous cost-performance ratio, high efficiency, small design, and reliability. EGP are conceptually simple machines, but the design is often difficult, especially to ensure good performance at high working pressures. Among the internal components of EGP, the lateral plates are two important elements that strongly affect the performance of the machine. In this work, computational fluid dynamics (CFD) simulations are performed to investigate the effects of plate with textured surfaces and gear with chamfered edges on the bearing capacity. The simulations of the fluid flow in the oil gap between the gear tooth and the side bushing consider the correct pressure distribution at the inlet and outlet of the meatus, involving in the simulation also the portion of oil in the tooth space volumes surrounding the tooth.
