Dalton Model "OSD" Overload Safety Device

0·0 reviews

(102) The Dalton "OSD" is a torque-limiter unit which prevents costly breakdowns when equipment is overloaded, by disengaging when a set maximum load is reached. The unit is re-engaged immediately when the overload is eliminated. The "OSD" is easily adjusted with a torque-wrench to the specific torque required. It can be used with a sprocket, gear, belt-pully, or flange. The clutch facings used, have been selected after research and testing, to resist expansion due to moisture. The flanges are high carbon steel forgings, machined accurately for precise operation. The threaded hub and pressure plate are machined square and ground where necessary to position the plate and eliminate extra parts. The torque adjusting nut is hexagonal for easier installation and adjustment. Equipped with needle bearings to eliminate shaft scoring, seizing, and wear. Use only specially ground sprockets. The Dalton "OSD", Overload Safety Device Unit, is equipped with a single torque adjusting nut for torque uniformity. Only one setting on the single e nut applies equal pressure on the entire unit, whereas the use of multiple e nuts would make it extremely difficult to equalize the pressure and would defeat the purpose of a positive release. A standard pipe wrench, which is readily available everywhere, may also be used to adjust this nut. Fibers are 1/8" thick. FORMULA FOR TORQUE-HORSEPOWER (Foot Pounds) TORQUE (Foot. Pounds) = (HPx5252)/RPM HORSEPOWER = (Torque x RPM)/5252 Important Notes: The "OSD" overload safety device can be made to suit your application. Send us your blueprints or specifications, for recommendations by our engineering department. Dalton Overload Safety Devices can be plated with cadmium, chrome and zinc. Sprockets can be furnished in ferrous materials.

Dalton Roller Chain Shear Pin Coupling "RCSPC"

0·0 reviews

(439) A complete line of Dalton Shear Pin (torque limiter) Roller Chain Couplings was developed for applications where horsepower and torque or high or extreme accuracy is desired for torque settings. The coupling halves are hobbed with a special tooth form and hardened 45 to 50 Rockwell "C". Roller chain couplings, when used correctly, are unsurpassed by any other more expensive coupling. Standard sprockets should not be used for coupling applications. The Dalton Roller Chain Shear Coupling (RCSPC) has an accurate torque release obtained by precision machining of the shear pin neck diameter and material used. The maximum capacity in inch pounds is up to five times greater than the rated capacity of friction type torque limiters. When loads occur beyond the rated capacity, the pin shears at the neck. A new pin when installed allows operation of the equipment with no damage to any part, mechanical or other wise. The pin must be replaced with a Dalton Shear Pin or equivalent. Maximum capacities range from 738 inch pounds to 66.504 inch pounds. Gear Shear Pin Couplings (GSPC) are available to order. Our engineering department is available for more information or when stock sizes do not suit your needs. Please call for discounts on list prices.

Dalton Model "OSDC" Overload Safety Device Coupling

0·0 reviews

(656) The Dalton OSDC (Overload Safety Device Coupling) provides overload protection through the use of an OSD unit combined with a roller chain coupling half counterbored to fit the OSD flange. Standard double-width roller chain is used to couple the basic OSD unit and the coupling half. The OSDC can be set with a torque wrench for maximum load desired. The unit functions as a roller chain coupling until an overload occurs, causing the OSDC to disengage. The device is automatically re-engaged when the overload is eliminated. FORMULA FOR TORQUE-HORSEPOWER (Foot Pounds) TORQUE (Foot. Pounds) = (HPx5252)/RPM HORSEPOWER = (Torque x RPM)/525 In furnishing a coupling half to be used in the "OSDC", care must be taken that a standard cut tooth sprocket is not used. The teeth of the "OSDC" coupling half are cut with a special tooth form to compensate for shaft misalignment. Important Note: The "OSDC" overload safety device can be made to suit your application. Send us your blueprints or specifications, for recommendations by our engineering department.

Dalton SOS Safety Overload Switch

0·0 reviews

(13) Turns off power source at pre-set load limit The Dalton SOS Safety Overload Switch is designed specifi cally to insure against breakdowns in all types of driven machinery by providing automatic shutdown at the precise moment an overload occurs. The proven reliable SOS Safety Overload Switch reduces downtime and production loss in medium and heavy duty chain driven systems by shutting off power before excessive torque can cause costly damage to mechanical components. One model can accommodate chain drives of %-inch pitch #60 chain to 2-inch pitch #160 chain. A final spring adjust ment screw permits rapid, easy pre-setting for maximum desired load regardless of chain pitch and size. The Dalton SOS Safety Overload Switch is effective, eco nomical insurance against heavy-duty chain drive overloads in a wide range of applications. Other procket sizes available. Sensing springs available in various sizes determined by application. IMPORTANT NOTE: Please call for discounts on list prices. Dimensions: Overall Height 8", Width 4x4", Length 9" Weight: SOS #1 9#, SOS#2 17#

Dalton Model "ROSDC" Rigid Overload Safety Device Coupling

0·0 reviews

(484) The Dalton ROSDC (Rigid Overload Safety Device Coupling) provides overload protection through the use of an OSD unit combined with a rigid coupling half counterbored to fit the OSD flange. All steel rigid coupling half is bolted to a basic OSD unit to form a rigid coupling with the overload feature. The ROSDC can be set with a torque wrench for maximum load desired. The unit funcitons as a rigid coupling until an overload occurs, causing the ROSDC to disengage. The device is automatically reengaged when the overload is eliminated. FORMULA FOR TORQUE-HORSEPOWER (Foot Pounds) TORQUE (Foot. Pounds) = (HPx5252)/RPM HORSEPOWER = (Torque x RPM)/5252 Important Note: The "ROSDC" overload safety device can be made to suit your application. Send us your blueprints or specifications, for recommendations by our engineering department.

Dalton Model DRC Steel Rigid Couplings

(8) The Dalton "DRC" RIGID COUPLING is designed for speeds up to 3600 RPM. The shaft size determines the coupling to be used. Extreme care for perfect alignment must be exercised. Please call for discounts on list prices.

Dalton Sprockets For Use In OSD Units

0·0 reviews

(262) Specialy ground sprockets are recommended for use with all Torque Limiters. Both faces of Dalton OSD sprockets are ground to approximately a 32 micro-inch finish. Uniform surfaces and parallel faces insure that Dalton OSD's will maintain proper torque release and re-engagement much longer than units without special sprockets. In addition, fibers last longer and OSD's require less maintenance. Price Each Not Hardened
