Improvement of gear hydraulic machines by meshing geometry
Abstract
Depending on the design of gear hydraulic machines, they are used as pumps, motors and flow dividers at pressures up to 28-30 MPa in power hydraulic systems of machines. In the pressure range of 0.3-2.5 MPa pumps are used in the lubrication systems of engines, transmissions of various working machines, in compressors. Gear pumps are also used for pumping and transportation of liquids and quasi-liquid media with temperatures up to 250 ° C and viscosity 1-3800 cSt, including aggressive and abrasive media.
