✦ Synopsis
Some results of an industrial research and development project aimed to develop the manufacturing technologies of gear pumps were presented. Gear blanks of gear pumps that have traditionally been produced by machining from round bars in an industrial company were closed-die forged as an alternative. A comparison method of mechanical properties of the manufacturing methods was published formerly. A classical method was applied to calculation of press loads in closed-die upsetting of gear blanks of gear pumps and results were compared with those of measured in the experimental part of the work. Commercially pure lead was used as test material. In addition to comparison of calculated and measured loads, contributions of the method applied on the manufacturing costs of gear blanks were also discussed in the study.
