Adjustable Pitch V-Belt Pulleys
V-belt pulleys (also called sheaves) are used with V-belts to transfer motion from motors to belts, fans, and pumps. They have V-shaped grooves corresponding to V-shaped belts to prevent slippage and misalignment. V-belt pulleys provide maximum friction and torque in compatible V-belt drive systems. Available in single or double grooves, they offer a pitch range from 1.9 inches to 6.7 inches (A belt) and 2.4 inches to 7.0 inches (B belt). 1VP and 2VP series are finished bore variable speed sheaves made of cast iron and designated for heavier duty service up to 25 HP. Variable pitch pulleys are used with 3L, 4L, 5L, A, B, or 5v belts.

Installation and Removal of Pulleys
Install
- Check the pulley groove to make sure there are no scratches or sharp edges and all dimensions are up to standard;
- Clean the surfaces of all parts, such as hub holes, taper sleeves, bolt holes, etc. Fit the cone sleeve into the pulley, aligning all the screw holes.
- Apply oil to the screw (TB 1008-TB 3030) and thread (TB 3525-TB 5050) and screw them into the mounting holes, but do not tighten them yet.
- Clean the surface of the drive shaft, push the pulley with the tapered sleeve installed to the predetermined position on the shaft, and check whether the V-belt pulley is aligned.
- When using the keyway, it must be inserted into the hub first, and there must be a certain tolerance between the keyway and the hole hub.
- Using a hexagonal wrench conforming to the DIN911 standard, alternately, gradually, and evenly tighten the bolts in each mounting hole until the torque shown in the table below is reached.
- After a short period of operation (0.5 to 1 hour), check the tightening torque of the bolts and retighten them if necessary.
- To prevent the intrusion of foreign matter, fill the hole’s connection hole with grease.
Disassemble
- Loosen all the bolts, take out one or two of the bolts according to the number of disassembly holes, lubricate the bolt pattern and the tip of the bolt with oil, and insert the bolt into the disassembly hole.
- Tighten the bolts alternately until the taper sleeve and pulley are loosened.
- Remove the taper sleeve and pulley from the shaft.
