Gear hobbing and gear shaping are both common generating processes in gear manufacturing, but they are not interchangeable. Hobbing is usually the more efficient choice for standard external spur and helical gears, while shaping becomes more practical when the tooth geometry or cutter access makes hobbing difficult. For buyers, the process choice should start with […]
Gears operate under constant loads, repeated meshing, friction, and shifting temperatures. Over time, they can develop issues like pitting, wear, galling, cracks, and broken teeth. In high-speed and heavy-duty applications, a single gear failure can ripple through and disrupt the entire transmission system. Gear failure is rarely caused by a single factor. Material selection and […]
At first glance, sprockets and gears can look like parts that do the same job. Both pass rotary motion and torque from one shaft to another. The difference is in how they do it: gears work through direct tooth-to-tooth contact, while a sprocket normally drives a roller chain, and the chain carries motion to another […]
Spiral bevel gears are used in car drivetrains, farm machinery, construction equipment, and industrial drives. They run smoother than standard gears, carry more load, and transmit power better. That’s why they’re often chosen for jobs where reliable power transfer matters. Their curved teeth, though, are tricky to manufacture accurately. After heat treatment, gear makers traditionally […]
Choosing the right bevel gear manufacturer is a critical step for companies sourcing precision transmission components. While many suppliers can produce bevel gears, differences in manufacturing capability, gear accuracy, material control, and inspection processes can directly affect product performance, assembly reliability, and long-term operating stability. For custom bevel gear projects, buyers need to evaluate more than […]
When a vehicle turns, the wheels on both sides naturally need to rotate at different speeds. The outer wheel travels a longer distance, while the inner wheel moves a shorter distance. An automotive differential gear system makes this possible by distributing power smoothly while allowing each wheel to rotate at the speed it needs. For […]
Small pits on a bevel gear tooth are often blamed on poor material or low hardness. Those are possible causes, but they are rarely the only ones. Pitting usually develops when repeated contact stress acts on a local area that is carrying more load than expected. The contact pattern, mounting position, lubrication, tooth finish, heat […]
Two gears can rotate normally and still have less-than-ideal meshing conditions. Besides module, tooth count, pressure angle, center distance and tooth form, gear contact ratio is another important parameter for evaluating whether a gear pair can transmit motion continuously and smoothly. In simple terms, contact ratio describes how many pairs of teeth are involved in transmitting […]
On gear drawings, pressure angle values such as 14.5°, 20°, and 25° often appear alongside module, tooth count, and other basic geometry. Although it looks like a simple angle, it affects the tooth profile, meshing behavior, tooth-root strength, and load direction within a gear pair. Among modern involute gears, 20° is widely used as a standard […]
Introduction A cylindrical gear vs bevel gear comparison starts with the shaft layout. If the shafts are parallel, spur or helical gears are usually the starting point. If their axes intersect, bevel gears may suit the drive. The next question is whether that arrangement can handle the load within the available space. For buyers working […]
