ComInTec Compact Pulley/Belt Drives

  • Symmetrical Pulley for Standard V-Belts

  • Fixed Diameter Drive Pulley.
  •  Distance between shafts change self tensioning Compact pulley.
  • Speed Range - to 2.5:1 variable.
  • Suitable for Forward & Reversing operations.
  • Power range from 1/2hp (0.37kw) to 2hp (1.5kw).
  • Use with TVT adjustable motor bases or your distance fixtures.
ComInTec VAR.D.E.A.C. Compact series uses standard V-Belts such as A, B, C or the lighter 3L, 4L, 5L, as well as Metric 10, 13, and17mm.  The design uses a single helical spring to allow tension adjustment on one side (typically opposite the motor), while working with a fixed diameter sheave on the driven side.  A sliding motor base is typically used to adjust the center distance between the Compact and Fixed diameter pulley, as distance is increased the pulleys spring side adjusts to allow the belt to maintain constant tension while reducing the effective diameter of the driving pulley.  Conversely, as the distance is reduced the springs tension forces the spring side of the sheave to move inward, increasing the effective diameter of this pulley.   

The Compact adjustable speed pulley is simple in design but well executed.  The pulley is made of steel, galvanized for corrosion resistance,  utilizes a self lubricating sliding hub for a long maintenance free operation.   Pricing is very aggressive, thus a simple, reliable, easy to service system using standard belts and pulleys can be employed to create adjustable speed by means of changing belt drive ratio is found in the Compact. 

The limits to the Compact are its power range, which is from fractional to 2hp and its possible ratios are limited to its change in diametrical pitch of about 2.5/1.   Selecting the driven pulley from minimum to maximum of the Compacts diametrical pitch will determine if the Compact is used as a Speed UP, or Speed Down ratio adjuster.
