Ameriloc Hydraulic Shaft Locking Devices

Ameriloc® hydraulic shaft locking devices
provide secure shaft/hub connections

Through an exclusive agreement with TAS Schafer GmbH, Ameridrives Couplings now offers hydraulic shaft locking devices. Tas-Schäfer is located in Wetter Wengern Germany, manufacturing high quality products using the latest in CNC technology.TAS Schäfer was founded in 1962 and is now a successful company supplying first grade components to an ever increasing international market.

Custom-manufactured to precise tolerances per customer specifications, Ameriloc locking devices are highly engineered to provide years of trouble-free service with features including:

• Zero backlash
• Reduced shaft stress
• High contact pressure for greater torque
• Easily installed and removed
• Elimination of keyways or splines
• Unlimited shaft positioning

The great advantage of the hydraulic SHS device lies in the significant time savings during installation. This system can be tensioned at a pressure of between 1740 and 2900 PSI (120 and 200 bar). With larger diameters, such as 20.8 in. (530 mm), the SHS can be tensioned within only a few minutes, compared to several hours required for a mechanical locking device. This time reduction increases exponentially with the diameter of the connection. View Hydraulic Pump Kits.

The hydraulic pump required for assembly can be a stationary unit, e.g. at test stations and assembly areas, but the use of a hydraulic hand pump is also possible. In this way, the system can also be tensioned at difficult-to-reach places such as the turret of a wind turbine. Dismantling of the SHS is also supported by the hydraulic system.

If the seals no longer work after many years of operation, the SHS can be removed like a mechanical locking device by loosening the screw connection to release pressurization.

• All units are pre-assembled, ready to install
• Torque range from 25,077 to 4,303,675 ft.lbs. (34 to 5,835 kNm)
• Hub diameters from .55 to 29.52 in. (165 to 750 mm )
• Shaft diameters from 4.53 to 25.20 in. (115 to 640 mm)
• Additional sizes are available upon request

Surface Finish:
Recommended surface finish for shafts and hubs to be used is at maximum 63 RMS or 16 μm.

Test Stand Applications

With approximately 35,000 wind energy turbines in the US coming out of warranty, one of the fastest growing markets in renewable energy is wind turbine gearbox repair facilities. Traditionally this market was serviced by European companies, but due to high shipping costs and long lead times, this service is now being sought out domestically.

There are currently 5,600 MW of new projects under construction in 2011. The US Department of Energy envisions that wind power could supply 20% of all US electricity by 2030.

Ameridrives offers verities of components that are applied to many different test stand configurations. Weather the test stand is for end of production or gear box repair facilities, verifying output speed or vibration characteristics.

Hydraulic Locking Devices

• Used on test stands to allow for a keyless shaft to hub connection with quick and easy installation and removal.

Stub Shafts & Flange Connections

• Utilized for bolted connections allowing for quick gearbox changes.

U-Joints & Flexible Couplings

•  Allows for angular misalignment and high torque capacity.

Applications

Ameridrives hydraulic shaft locking devices are offered in a wide range of sizes for use on all types of industrial applications including:
