The process of selecting small inch size drive components for new prototypes or production applications just became easier.
Fasteners get to grip with hubs
Fastening rotating components to shafts has become easier with the publication of the new 96-page "Handbook of Fairloc components, the integral fastener".
Identified as the A 6D16 Series, these 17 MXL pulleys are made of gold iridite aluminium alloy and are available from stock in 12 to 72 grooves.
Bore sizes range from 0.125 to 0.25in and ODs range from 0.286 to 1.813in.
They are available in double- or no-flange types.
SDP stocks a wide variety of other MXL size pulleys in different materials and for different belt widths.
The Fairloc integral hub fastener consists of two slots that are machined into the hub, one 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.
