Fluid drive applications that require an output speed that is faster than the input speed can utilize a gear set as a speed increaser. Theoretically, a gear box can increase the speed either before or after the fluid drive. However, it is usually better to increase the speed before the fluid drive because the size of the fluid drive parts are dependent on rotational speed at the hydraulic coupling: The faster the impeller, the smaller the parts.
TRI can make fluid drives with internal gears. A fluid drive with internal gears has two main advantages over a gear box external to the fluid drive. Machine trains that use fluid drives with internal gears have a smaller overall footprint then placing a gear box between the driver and the fluid drive, and fluid drives with internal gears eliminates the coupling between the drive and the fluid drive.
