Hydraulic Motor - Gear Category
These consist essentially of two intermeshing toothed gears enclosed in a common housing. A shaft, the output shaft, extends beyond the housing. This shaft is attached to one of the gears which, in turn, drives the second gear. The hydraulic fluid is trapped in the gaps between the gear teeth and propelled along the inside of the housing from the pressure inlet port to the suction outlet port.
Hydraulic Motor - Gerotor / Geroler Category
The H series motor uses a Gerotor while the rest of the Char-Lynn motors use a Geroler. The difference is shown in the picture to the right: Essentially a Geroler' has rolls added to the lobes of the outer ring of the Orbit gear set. These rolls act as a roller bearing and reduce friction, increase mechanical efficiency and reduce wear in systems with low fluid viscosity. In addition, the Geroler type typically provides smoother performance at low speed conditions.
