Avon Gear & Engineering Co.

United States

Avon Gear & Engineering manufactures a full line of custom helical gears and drives. We manufacture high quality helical gears for many industries, from small to large in a variety of size ranges. What are helical gears?Helical Gears have teeth which are set at an angle. Helical gears and spur gears are very similar except that the teeth of a helical gear are cut at an angle to the axis or hole. These teeth typically engage more slowly and smoothly than spur and other types of gears used for similar applications, because the load is transferred uniformly and gradually. This results in superior performance and reduced noise and vibration. When used on parallel shafts, helical gears are similar to spur gears, but generally provide a stronger, smoother running gear train. When used on shafts at right angles, these helical gears are commonly known as spiral gears or crossed axis helical gears. Helical gears are made in both right and left hand configurations. Accurate gears require accurate gear blanks; for better control at this critical stage of gear manufacturing, Avon Gear manufactures custom helical gears with our own gear blanks. We also have the capabilities to manufacture custom helical gears in a variety of materials.

Spur gears are a very common type of gear and in many cases they are the most cost effective type of gearing. They generally have straight teeth and transmit motion & power between parallel shafts. Spur gears are used in many devices & industries including: Electronics, Construction equipment, Machine tools, Conveyors and Material handling. They are typically not used in automotive applications because they can be noisy. The Spur Gear AdvantageSpur gears, also known as straight cut gears, have a number of advantages over other types of gears. Spur gears are easy to design and manufacture and are also more efficient than helical gears. Straight cut gears provide increased efficiency because helical gears produce more heat due to the fact that they have sliding contacts between teeth which produces axial thrust. When applications require simple, easy to assemble gears, spur gears may be the ideal gear for you. Spur gears are also known for their reliability and constant velocity ratio.

A planetary gearset, also referred to as epicyclic gearing, has three components; the sun gear, the planet gears' carrier and one or more planet gears, and the ring gear. With these three components, different gear ratios can be produced depending on which gear you use as input, which gear you use as output, and which gear is held still. The ratio of input rotation to output rotation is dependent upon the number of teeth in each gear, and on which gear is held stationary.The chief benefit of planetary gearing is that the input and output are in line. Many planetary gearboxes are attached to a motor to reduce the speed of the motor and create more power. Planetary gearing can be added in stages using a common ring gear with multiple suns and planets. Avon Gear makes custom planetary gear components and complete assemblies. They can be made from a wide variety of materials depending on the application. Contact Avon Gear today to learn more about our planetary gear capabilities.

Internal spur gears, also know as ring gears, have the same standards as an external spur gear except that the teeth are cut into the inside diameter while the outside is kept smooth. Internal gears can provide a compact solution that delivers large speed reductions and reduced sliding wear action and can be applied in a wide range of equipments & applications. Internal gears are widely used in light duty applications. When it's necessary to have two parallel shafts rotate in the same direction, internal gears eliminate the need for an idler gear.internal ring gears We can custom manufacture internal gears from a variety of materials that include: steel, stainless steel, heat treated steel, sintered steel, tool steel, ductile iron, gray iron, brass, bronze, copper, cast iron, aluminium, plastic & phenolic. Services include precision blanking, sawing, milling, drilling, tapping, broaching & finishing.
