Gear pumps with external gear

U radu je napravljena je podjela hidrauličkih pumpi, za svaku je dan opis. Opisana su neka ograničenja u radu hidrauličkih pumpi. Detaljno je opisana zupčasta pumpa s unutarnjim i vanjskim ozubljenjem te je napravljena podjela prema ozubljenju zupčanika, prema obliku zuba zupčanika, broju pari zupčanika i pumpi, mogućnosti regulacije protoka, korištenju tlaka tekućine za povećanje radne sposobnosti. Opisana su područja primjene zupčastih pumpi. Glavni dio rada je konstrukcija i proračun zupčaste pumpe s vanjskim ozubljenjem gdje su date slike pojedinih dijelova zupčaste pumpe s vanjskim ozubljenjem te proračuni za zupčastu pumpu s vanjskim ozubljenjem. Na kraju rada napisane su prednosti i nedostatci ranije spomenutih pumpi s vanjskim ozubljenjem.This work aims to explain of gear pumps gives the classification /subdivision of different gear pump types. Each one has been given a description and principle of its work. Some limitations of gear pumps work have been explained. Gear pump with external and internal gear has been described in detail. The division of toothed gears includes the shape of toothed gear, number of paired toothed gear and pump, the possibility of regulating the flow, the use of fluid pressure to increase working ability. This work also describes the fields of applications for gear pumps. The most important part of this work is the construction and calculation of gear pumps with external gear where pictures of separate parts of gear pumps with external gear and calculations for the gear pump with external have been given. The work is ended with pros and cons list of earlier mentioned pumps with external gear
