Steel V Belt Pulley

HM- Your Custom Steel V-Belt Pulley Expert

Steel v-belt pulleys also named vee belt sheaves are used to transfer power between axles via a mechanical linkage. It offers a high-speed power transmission solution, which is resistant to slipping. Additionally, steel v-belt pulleys are designed for use with V-belts to transmit movement from motors to pumps, fans, and belts.

The steel v-belt pulleys provide the highest torque and friction in compatible v-belt systems. They come with V-shaped groves coordinated with V-shaped belts to stop misalignment. These devices are manufactured with a standard configuration such as plain bore, bushed type, idler, and finished bore.

Different Types of Steel V-Belt Pulleys

Standard V-Belt Pulley
Standard V-Belt Pulley
  • A pulley that has conventional dimensions.
  • With numerous grooves, which partnered with small-engine, hexagonal-style, and classic v-belts.
Companion Pulley
Companion Pulley

The companion pulley contains vital spokes that operate spirally on the pulley. It can make a high strength-to-weight ratio, which is advantageous to apportioned horsepower pulleys.

Idler Pulley
Idler Pulley

This type of pulley is used exclusively as a belt tensioner in numerous v-belt drives. However, it plays a vital part in sustaining the tension needed to drive the transmission. The idler also interacts with the flat side or wedged of the v-belt.

Variable Speed Pulley
Variable Speed Pulley

The variable speed pulley has the variable pitches that adjust the driven RPM within a range represented as a percentage. This pulley is useful to sustain belt tension for a dynamic load.

What happens when the V-belt pulley goes bad?

Typical signs for Bad V-belt pulley: Squealing noise, faulty Bearing & More, one of the common symptoms for bad V-belt pulley is that a squealing sound occurs in the engine belts. This phenomenon is attributed to the worn-out surface of the pulley belt. Due to insufficient motion from the pulley, the friction appeared between the belt and pulley’s surface, causing the noise.
