Our precision machined gear shafts come in a wide range of diameters, from miniature gear shafts to larger gear shafts. Here are some of gear shafts and miniature gear shafts we have designed and manufactured recently: What are Gear Shafts? Gear shafts are a critical component of gear assemblies. Gears shafts attach to a toothed wheel (the gear) or a rack and rotate it so it can engage and turn another gear. Gear shafts come in varying lengths and diameters and can rotate gears at a wide range of speeds. A typical mechanical device might employ multiple gear shafts and gears in a variety of configurations to achieve a desired rotational or linear movement and force. How Gear Shafts Work Gear shafts rotate to enable one gear to engage and turn the teeth of another gear. Gears are used to transfer motion and torque between machine components in mechanical devices without slipping. If the gears in a system are of different sizes, they can be used to increase torque: The smaller wheel turns more quickly but with less force, while the bigger one turns more slowly with more force. Types of Gears There are many types of gears, the most common of which are below. Norca Precision experts will help you determine the most efficient gear / gear shaft solution for each application, promptly developing and delivering high-quality finished product. Spur gears: The most common gear type, spur gears have straight teeth that sit parallel to the wheel’s axis and gear shaft. They have cylindrical pitch surfaces and can achieve high precision, without creating any load (thrust load) in the axial direction. Helical gears: A helical, or spiral, gear is a cylindrical gear with twisted, screw-like teeth. Helical gears are used to transmit power between parallel or nonparallel gear shafts. Helical gears have tighter teeth meshing than spur gears, making them suitable for transmitting higher loads within high-speed applications. Helical gears, unlike spur gears, generate thrust along the gear’s axis; this must be accommodated for by thrust bearings. Bevel gears: Bevel gears have tapered teeth and a conical shape. They are most commonly used to transmit force between two gear shafts that intersect at one point (this setup is called an ‘intersecting gear shaft’). Bevel gears come in a variety of profiles, including straight bevel, zerol bevel, spiral bevel, miter bevel and crown bevel gears. Crown gears: Crown gears are a special type of bevel gear in which the gear’s teeth project out at right angles to the plane of the wheel, looking like a crown. Crown gears typically work in gear systems with other bevel gears, but can be configured to work with simpler spur gears. Miter gears: A form of bevel gear, Miter gears have an equal number of teeth on both faces, and work with gear shafts that are at right angles to one another. Worm gears: A worm gear is a special type of helical gear, in which the angle is large (close to 90 degrees) and the body length is long in the axial direction, such that it resembles a screw. Worm gear systems are a simple way to achieve a high torque, low speed gear ratio. Gear rack: Gear racks (also called ‘rack and pinion’ setup) are used to transform rotational motion into linear motion and vice versa. A gear rack setup consists of a cylindrical gear and a linear gear (the rack), which is typically a flat surface or a straight rod. Both gars have the same sized and shaped teeth cut at equal distances. Hypoid gears: Hypoid gears are similar to spiral bevel gears except that their shaft axes do not intersect. Rather, Hypoid gears are usually designed to operate with shafts at 90 degrees. Depending on the configuration, contact between hypoid gear teeth may be even smoother than with spiral bevel gears. External vs. Internal gears: The gears outlined above are external gears, with teeth placed on the outer surface of the cylindrical or conical gear. Internal gears are also available, in which the teeth sit on the inner surface of the gear. Gear Shaft Configurations A good way to think about types of gears and gear assemblies is to consider the configurations of the gear shafts to which they connect. At Norca, our gear shafts are designed for highly efficient motion controls and power transmission for any desired setup. We support all three types of gear shaft configurations: Parallel Axes: In this most common configuration, the gear shafts sit parallel to one another. Spur gears, helical gears, gear racks (rack and pinion) and internal gears all work with parallel gear shaft setups. Intersecting Axes: In this configuration, gear shaft axes intersect at a single point. Miter gears, straight bevel gears and spiral bevel gears work with this gear shaft setup Nonparallel, Nonintersecting Axes: As opposed to the two configurations above, this setup works with gear shaft that are at an angle to one another; in the case of a Worm gear, the angle is 90 degrees.
