Hydraulic Pump Animation: External Gear Pump [Spur Gear]  

One of the common applications for spur gear can be found in “Hydraulic pumps”. In this animation, we are showing you an external gear pump. An external gear pump utilizes two identical spur gears meshed side-by-side. The top gear is driven by a motor, and it drives the bottom gear. Each gear is supported by a shaft with ball bearings on both sides of the shaft. Fluid trapped between the gear teeth is displaced from the inlet to the outlet port. The gear mesh at the center will act as a seal between the ports. If you are interested to learn more about other type of gears and how they function in other engineering application, please check out our channel @CAE+ for the full video for “Basics of Gears”.
