Timing Pulleys

Timing Belt Pulleys – including v belt pulleys and poly vee pulleys

We can manufacture timing pulleys from 3mm diameter, up to 3 metre diameter.

We can manufacture any pitch to suit any belt you require.

Some Timing belt pulley pitches for example although there are too many to list here

“L” “XL” “H” “XH” “XXH” “3M” “5M” “8M” “14M” “20M” “T3” “T5” “T10” “T20” “AT3” “AT5” “AT10” “AT20” “YU”

These are available in a huge range of tooth pitches (inch and metric), materials, lengths and widths.Timing belts are the ideal stock solution for economical synchronous drives.

Timing belts, (also known as Toothed, Notch or Cog) belts are a positive transfer belt and can track relative movement. These belts have teeth that fit into a matching toothed pulley. When correctly tensioned, they have no slippage, run at constant speed, and are often used to transfer direct motion for indexing or timing purposes (hence their name). They are often used in lieu of chains or gears, so there is less noise and a lubrication bath is not necessary. Camshafts of automobiles, miniature timing systems, and stepper motors often utilize these belts. Timing belts need the least tension of all belts, and are among the most efficient. They can bear up to 200 hp (150 kW) at speeds of 16,000 ft/min, and there is no limit on speed.

Timing belts with a helical offset tooth design are available. The helical offset tooth design forms a chevron pattern and causes the teeth to engage progressively. The chevron pattern design is self-aligning. The chevron pattern design does not make the noise that some timing belts make at idiosyncratic speeds, and is more efficient at transferring power (up to 98%).

Disadvantages include high starting price, grooving the pulleys, less protection from overload and jam, no clutch action, and backlash

Other types of transmission pulleys can also be manufactured for example V belt pulleys and poly vee pulleys. Timing pulleys with any pitch or form can be ordered, contact us for more information.
