## What are belt sheaves?

V-belt pulleys (also called vee belt sheaves) are devices which transmit power between axles by the use of a v-belt, a mechanical linkage with a trapezoidal cross-section. Together these devices offer a high-speed power transmission solution that is resistant to slipping and misalignment.

## How do you size a sheave?

Use a Ruler to Measure the Sheave This is simple — lay the ruler’s edge across the center of the sheave and measure the diameter. With that measurement, you can calculate the ID by measuring the depth of the groove. Following the same example as before, suppose you measure 100mm across the sheave – that’s the OD.

How is pulley sheave measured?

Place your pulley face down on a flat surface, then put your ruler or caliper on top, measure from outside edge to outside edge across the circle of the pulley. Check carefully to make sure you are measuring across the center.

What type of pulley is a sheave?

When business owners or homeowners talk about a sheave, most are referring to a smooth pulley for use with a cable, rope, or v-belt. On the other hand, when they discuss their need for a pulley, a timing pulley is often referenced!

### What is a sheave in pulleys?

Sheaves and pulleys are wheels with a flat or grooved edge that transmit rotational force from one shaft to another when connected with a V-belt or gearbelt. They are used to power fans, pumps, and conveyors. Idlers maintain consistent tension on belts to reduce slippage and move belts away from obstacles.

### What is pitch diameter of a sheave?

In terms of sheave dimensions, the pitch diameter is now equal to the outer diameter for most standard sheaves. The datum diameter, however, is slightly less than the outer diameter.

What is sheaves used for?

A sheave (/ʃiːv/) or pulley wheel is a grooved wheel often used for holding a belt, wire rope, or rope and incorporated into a pulley. The sheave spins on an axle or bearing inside the frame of the pulley.

What is the function of a sheave and pulley?

Sheaves and pulleys are round wheels with a flat or grooved edge that transmit rotational force from one shaft to another when connected with a V-belt or gearbelt. They are typically used to power fans, pumps, conveyors, and other industrial machinery. Idlers maintain consistent tension on belts to reduce slippage…

## What kind of pulleys do I need for my shafts?

Mount these pulleys with a taper-lock bushing for a tight, wobble-free hold on your shaft. These pulleys are cast iron. Choose from nylon, UHMW, and zinc.

## What is the difference between xL and H series pulleys?

Pulleys are XL series (extra light) and have trapezoidal teeth. Move heavy loads without slippage— pulleys mount with a bushing for a more secure grip on the shaft than set screws. Pulleys are H series (heavy) and have trapezoidal teeth.

What is a step-cone pulley?

Also known as step-cone pulleys, these have multiple groove sizes so you can quickly change rotation speed by moving your belt to a different groove. A built -in spring maintains tension on your belt.
