FLAT BELT DRIVES EBOOK


Idler pulleys are pressed against the belt and guide them. They change direction and increase the angle of contact. It can provide a high-velocity ratio.

Idler pulleys can also reduce the vibration in the belt. Stepped or cone pulley drive They are used to get different velocity ratio during the power transfer.

The driver shaft rotates flat belt drives constant speed, driven shaft flat belt drives run at a different speed as the belt shifting from one cone pulley to another.

Advantage of the flat belt drive The flat belts are very simple in design and cheaper. Smooth running and quiet running.

Narrow V-belts, flat belt drives a given width, offer higher power ratings than conventional V-belts. They have a greater depth-to-width ratio, placing more of the sheave under the reinforcing cord.

These belts are suited for severe duty applications, including shock and high starting loads. Banded V-belts solve problems conventional multiple V-belt flat belt drives have with pulsating loads. The intermittent forces can induce a whipping action in multiple-belt systems, sometimes causing belts to turn over.

The joined configuration avoids the need to order multiple belts as matched sets. Banded V-belts should not be mounted on deep-groove sheaves, which flat belt drives used to avoid turnover in standard V-belts.

Such sheaves have the potential for cutting the band of joined belts. Extremely worn sheaves produce the same result.

V-ribbed belts combine some of the best features of flat belts and V-belts. The thin belt operates efficiently and can run at high speeds.

Belt (mechanical)

The ribs ensure the flat belt drives tracks flat belt drives, making alignment less critical than it is for flat belts. Synchronous belts Synchronous belts have a toothed profile that mates with corresponding grooves in the pulleys, providing the same positive engagement as gears or chains.

They are used in applications where indexing, positioning, or a constant speed ratio is required. The first tooth profile used on synchronous belts was the trapezoidal shape Fig.

It is still recognized as standard. Recent modifications to tooth profiles have improved on the original shape.
