The Hilliard Corporation is a producer of Starter Clutch Drives, Electric Starter Assemblies, Hydraulic Starter Assemblies and Pneumatic Starters for use in aero derivative industrial turbine and reciprocating engine applications.
Hilliard starter designs and equipment are operating worldwide in pipeline, power generation and marine propulsion markets. Major starter-fleet experience has been achieved on General Electric, MAN Diesel & Turbo, Peter Brotherhood, Pratt & Whitney, Siemens, and Solar engines and auxiliary gear boxes. New application designs can be engineered through the combination of available motor-starter structures and overrunning clutch modules.
STARTER OVERRUNNING CLUTCH DRIVE
The Hilliard High-Speed Starter Overrunning Clutch Drive provides positive engagement and high torque on demand. Featuring a unique roller-ramp design, the clutch when engaged transmits power via the precision- machined cam and roller assembly connected to the input shaft. A ball bearing at each end of the roll cage supports and aligns the cam in relation to the drive (output) shaft.
HYDRAULIC CLUTCH ASSEMBLY
Variable and fixed displacement types. SAE mounting, spline shafts. Typical operating pressures up to 5000 psig (350 bar). High-speed operation. High starting torque efficiency. Different sizes for different applications. Suitable for open and closed loop circuits. Supply includes overrunning clutch.
ELECTRIC START ASSEMBLY
24 volt DC power. Solenoid actuated Positork drive. Output torque up to 80 ft lb. Splined output for gas turbine applications. SAE 3 mounting flange, multi- position. CW and CCW direction of rotation.
PNEUMATIC START ASSEMBLY
