Ameridrives Modified Amerigear Couplings for Oil & Gas Truck-Mounted Pumps
A leading oil and gas OEM needed a torque-dense disconnect coupling for pumps
utilized at hydraulic fracturing sites. The truck-mounted pumps are driven by
energy efficient electric motors instead of traditional diesel engines. The coupling
is installed between a 5,000 HP motor, turning at 1,800 RPM, and the pump.
The coupling allows the pump to be disconnected from the drive motor to prevent
drivetrain damage during vehicle transport.
Ameridrives was contacted by the OEM’s consulting engineer to provide a coupling
solution. After review of the application, Ameridrives supplied Amerigear FDC flexible
gear couplings with a torque rating of 551,000 in.lbs. The flanged-sleeve, doubleengagement
disconnect couplings with shifting collars are designed to meet quick
connection or disconnection application requirements. Units feature a high-speed
synthetic rubber lip seal that allows for disengagement. The 16" dia. couplings have
a 6" dia. keyed bore on the motor hub and a 5" dia. keyed bore on the pump hub.
Fully-crowned gear teeth provide operational benefits including maximum loadcarrying
capacity with minimum size, maximum reliability and long life. Optimum
separation of gear meshes permits high parallel offset capacity.
Amerigear models compensate for all three types of misalignment. Units feature
accurately machined medium carbon steel hubs and sleeves. Positive-type O-ring
seals keep lubricant in and contaminants out. Seals are enshrouded to prevent
damage.
