Royersford Foundry & Machine Co., Inc. - Royersford, PA
Manufacturer, Custom Manufacturer, Manufacturers' Rep
Manufacturer of rigid steel couplings, rigid flange couplings, rigid clamp couplings, & rigid jaw clutch couplings. Rigid flange couplings are used where the smallest overall length is necessary & ease of installation is not a factor. Couplings are fitted to the shafts & use tapered keys. Shaft sizes of 3-11/16 in. & above have male & female type construction. Rigid clamp couplings are used when ease of installation & removal is advantageous. Pulleys & bearings do not need to be removed for replacement. The coupling is bored with shims in place which are removed for installation enabling a clamp fit on the shaft over a straight key. Rigid jaw couplings are used to positively connect & disconnect rotating shafts where engagement & disengagement is not frequent. Couplings are machined all over to ensure precise engagement. Square jaws are used where engagement & disengagement under power or in motion is not required. They transmit power in both directions. Spiral jaw couplings are made in right or left hand style & will transmit power in only one direction. They can be engaged or disengaged at low speeds. Sprocket attachments are available to function as a chain drive.
