What do spur gears do?
Spur gears are used to transfer mechanical motion. They can also control speed, power, and torque. They work by transmitting power and motion between shafts through a series of gears.
The Elesa range of spur gears are made using high-quality technopolymer to comply with international standards. Available in black for general use and can come with pre-drilled pass-through holes. For use in the catering industry, our blue spur gears are produced from FDA compliant raw material.
What are the advantages of spur gears?
• Spur gears are simple. These transmission elements have a compact design that makes them perfect for use in restricted spaces.
• They have a constant speed drive. Spur gears perform at a constant velocity to increase or decrease shaft speed with a high degree of precision.
• Spur gears are reliable and durable. They are unlikely to slip during use and are long-lasting components.
• They are cost-effective. Thanks to their simple design, spur gears are easily manufactured at a low price point. At Elesa, we pass the cost savings onto you.
• Spur gears are efficient. With power transmission efficiencies between 95% and 99%, spur gears can transfer large amounts of power across multiple gears, with minimal power lossWhere are spur gears used?
Spur gears are versatile components that are used across several industries. They are commonly used in domestic appliances, construction equipment, machining, mills, fuel pumps, conveyors, and motors and gear pumps.
While spur gears can be used at most speeds, they are usually used for lower speed applications to avoid noise pollution and placing high stress on the gear teeth.
How do I choose the correct spur gear?
Spur gears are available in different module sizes. A module size is a unit of measurement for gear tooth sizes and indicates how big or small a gear is.
Our spur gears are listed in the Elesa catalogue under ‘Standard machine parts’. On the product page, you will see our black spur gears in module sizes ranging from 0.5 to 3.0, and our visually detectable blue gears in sizes of 1.0, 1.5 and 2.0.
You can browse the full selection of Elesa high performance and durable spur gears in our catalogue. Also in our range are accessories such as T-shape and square section racks, lead screw nuts, and toothed joints.
At Elesa we are more than happy to help. We can accommodate special executions on our spur gears, such as transversal grub screw assembly, non-standard gears, hubs with holes and keyways, and gears of various dimensions. If you require any assistance, please contact us.
