Our worms are available in coarse and fine pitches. Outside diameters range up to 6 inches and worm lengths range up to 12 inches. Avon can reverse engineer a worm or worm gear set when necessary. Worm drives can help decrease speed and allow higher torque to be transmitted. A gearbox using worms and worm gears will be more compact than one made from most other gear options.

A sector gear is a gear that has teeth along a short section of its circumference. The remaining portion of the gear is smooth without any teeth. Sector gears are used in applications when less than 360 degrees of rotations is required. In the areas where there are no gear teeth, the material can be removed. This can reduce weight and supply clearance. A typical application would be a valve actuator that only requires 90 degrees to open or close. Aircraft radar also would utilize this type of gear as it would only scan forward of the plans. An X-ray machine also uses dual sector gears. Sector gears can be manufactured as spur, helical, bevel, or even worm type gears. Avon Gear custom manufactures sector gears in a wide range of materials including aluminum, steel and stainless steel

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.

A spline is a series of teeth (splines) on a drive shaft that mesh with grooves in a mating gear. The surfaces of the two, the spline & the meshed gear, allow smooth transfer of force along a straight line of contact. We take pride in our quality control measures & often exceed AMGA standards to accommodate the intricacies of high precision splines & gears. Our engineering staff will design custom tooling to provide the required custom spline shaft, gear and shape, engineered to tight tolerances & specifications. Our staff will also help with analysis of new designs & improvements on existing designs. We offer standard & metric sizes for splines and can custom manufacture splines from a variety of materials. We have experience with different types of splines such as tapered spline shafts, high precision blind internal splines, involute and straight sided splines in a wide range of custom applications.
