This is usually the motor starting torque, but may also be any unusual momentary or shock load which may occur during normal operation. Step 2. Determine the largest pulley diameters that can be utilized, considering the space limitations and drive ratio of your system. This helps to increase the torque capacity of the drive and extend the service life of the belt. Step 3. Calculate the teeth in mesh (T.I.M.) using Formula 5 in Table 1. Consult Table 2 for the teeth in mesh factor. Divide the peak torque (from Step 1) by the T.I.M. factor to deter- mine the design torque by using Formula 7 in Table 1. Step 4. Calculate the belt pitch length based on the design center distance of your drive using Formula 2 in Table 1. Step 5. Divide the belt pitch length by the tooth pitch selected and round the result to the nearest whole number. This is the number of teeth on the belt for your application. Adjust the nominal center distance of your drive design to match the belt using Formula 1 in Table 1. Step 6. Using Formula 6 in Table 1, calculate the effective tension (Te) on the drive using the pitch radius and design torque of the smallest loaded pulley in the system. Step 7. (a) Select the strength factor for your application from Table 3. Divide the effective tension from Step 6 by the strength factor to determine the required break strength for the belt design. (b) Multiply by 2 to represent a double span break. Consult Table 4 to determine the required reinforcement type and belt width. The value listed in the table must be greater than the design break strength. Step 8. Using the torque capacity graph, select a belt width that is capable of handling the design torque with the selected pulley size. Note: This belt width may be different from the width selected in Step 7. The belt width required for the system will be the wider of the two. Step 9. Special Note: Limiting torque values must be multiplied by 0.45 for fiberglass reinforced belts. IMPORTANT NOTE Always incorporate a means of adjusting center distance to allow for pitch length manufacturing tolerance.

THE BETTER WAY TO FASTEN ROTATING COMPONENTS.Solves…Phasing, Timing, Positioning and Frequent Removal Problems

HERE’S HOW IT WORKS:Two slots are machined into the hub, one oriented radially, the other angularly, to create a transverse wedge which remains attached to the solid portion of the hub on one side. The resultant cantilevered clamping section has a tapped hole to accept a cap screw which passes through a clearance hole in the solid portion of the hub, and into a threaded hole in the transverse wedge section. As the screw is tightened, the cantilevered section clamps the shaft securely. The screw can be tightened and released repeatedly without marring the shaft or affecting its torque transmitting abilities.

PROVED MOST EFFECTIVE:For precision application – Lab tests proved Fairloc® to be superior to all other comparable fasteners. For high torque application – Torques up to 400 lbf in. are obtained with a 5/8" bore Fairloc® hub.

TYPICAL APPLICATION AREAS FOR FAIRLOC® INCLUDE:Computer Tape Drives, Aerospace Components, Aircraft Instrumentation, Aircraft Fuel Control Systems, Machine Tools, N/C Machines, Computer Input / Output Systems, Military Fire Control Systems, Medical Equipment, Business Machines, Optical Equipment, Power Drives.

FEATURES: Full Use Of The Bore - Gives maximum support to the component, reduces wobble or misalignment.Easy Adjustment - Fairloc® replaces set screws and clamps, eliminates marred shafts; components can be repositioned with a single hex key adjustment.Compact, Self-Contained Design - When available space or access is limited, Fairloc’s® small hub envelope is a distinct advantage.Very High Reliability

Call on our Engineering Department to discuss the advantagesof applying the Fairloc® concept to your designs.

A-TYPE SHAFTLOC®

PATENTED | SELF-LOCKING | VIBRATION-RESISTANT | INSTALLED WITH STANDARD TOOLS | REUSABLE

MATERIAL: 416 Stainless Steel, Passivated

SPECIFICATIONS:These vibration-resistant fasteners employ asymmetricthreads to self-lock. The two-piece unit uses the wedgingaction between the shallow thread inclines of the nut andbolt for self-locking when the nut encounters resistance.The nut turns freely until it contacts parts being clamped together and additional turns wedge them into a lockedand vibration-resistant condition.
