One of the types of volumetric pumps is a gear pump designed for pumping oil and petroleum products that have a lubricating ability, without mechanical impurities and do not cause corrosion of the pump’s working bodies, as well as for pumping light-duty liquids and diesel fuel. The authors have developed a new design of a gear pump with a two-axis connection. The new connection, which the authors called biaxial, consists of two parts with landing surfaces, one of which has a surface consisting of two cylinders with two axes, respectively. The use of a two-axis connection in the design of a gear pump allows ensuring the accuracy of the location of parts in the connection and the greatest alignment of the axes of holes and shafts, i.e. maximum alignment of the hole axes with the shaft axis or the axis of rotation, as well as the greatest contact between the shaft and hole surfaces, and ensuring that the shaft and hole axes are parallel. As a result of the study of the designs and technological requirements of gear pumps, a new type of “shaft-hole” connection was proposed in the designs of fixed joints, in particular the shaft-gear of the gear pumps. The use of a two-axis connection allowed us to offer a new design of the gear pumps with a two-axis connection confirmed by innovative patents of the Republic of Kazakhstan. The research was carried out within the framework of the grant №AP09562459. A method has been developed for selecting the location of the clearance fields of the landing surfaces of the two-axis connection in relation to gear pumps.
