Quick-Link - Gates Emergency V-belt Solution

Unplanned drive downtime can be expensive.  However, stocking numerous replacement belt sizes can also be costly.  The Gates Quick-Link V-belt offers an alternative.  It can be quickly assembled by hand into whatever length you need.  

Quick-Link is available in the following sizes:

Rim Speed Limits For Sheaves / Pulleys / Sprockets

Belt drive hardware has rotational speed limits in order to prevent excessive hoop stress levels that could result in physical material failures.  Material failures can be catastrophic with fragments thrown outward at high velocities and energy levels, so speed limits should not be exceeded.

Speed limits are based on the hardware material, as well as on the hardware configuration.  Block style hardware is inherently stronger than hardware with rims or spokes, so can operate at higher speeds.

Rotational speed limits are most commonly expressed in terms of rim speeds.  Common units used to express rim speed are feet per minute (ft/min) and meters per second (m/s).  Maximum rpm limits can be calculated from rim speeds with hardware diameters known.  An equation to calculate hardware rpm from rim speed is as follows:

RPM = (Rim Speed (ft/min) x 3.82)/Diameter (in)

A table from the Mechanical Power Transmission Association Standard B13i-2013 containing rim speed limits for a variety of hardware configurations and materials is as follows:

Belt drive hardware is often stamped with maximum rpm values, and will likely be based on this data.

Will It Fit - Poly Chain GT2 Sprockets

What belt will fit into what industry standard sprocket is a question we regularly receive here in Product Application.  Below is information regarding what Gates belts will fit into standard Poly Chain GT2 sprockets.  

**When designing belt drives for NEW APPLICATIONS with Poly Chain GT Carbon power ratings: DO NOT use Poly Chain GT sprocket systems.  Poly Chain GT sprockets/bushings may not handle the increased torque load capacity and damage to the sprocket and/or bushing may occur.  ONLY use Poly Chain GT2 sprockets for new designs.**
