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".
They are stocked in two hub styles, conventional pin type hubs which use a set screw for fastening and a Fairloc version.
Fairloc is a patented integral hub fastener which eliminates marred shafts.
The choice of Fairloc hubs permits frequent phase adjustment, timing and position adjustment while adding positive metal-to-metal fastening strength along both hub sections.
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.
They are stocked with both ribbed and smooth style centre sections.
The ribbed style features an angular misalignment of 5 or 15 degrees (long style) and a parallel offset of 0.25mm (short style) or 0.38mm (long style).
The smooth style features an angular misalignment of 1 degree (short style) or 8 degrees (long style) and a parallel offset of 0.13mm (short style) or 0.25mm (long style).
They are designed to fit 3 to 6mm metric shafts or 0.12, 0.125, 0.1875 and 0.25in shafts.
Detailed specifications are contained in SI catalogue 785 (metric) or 790 (inch) available free on request from Sterling Instrument.
