Crown Gear


What Is A Crown Gear?

A crown gear is a type of gear that has teeth that are cut on the outside circumference of a cylindrical or conical surface. The teeth are angled in such a way that they mesh with the teeth of a mating gear called a pinion gear. The crown gear is also known as a face gear, a contrate gear, or a crown wheel.

Crown gears are commonly used in applications where the drive shaft and driven shaft are at right angles to each other, such as in automotive differentials and industrial gearboxes. The crown gear is mounted on the driven shaft and meshes with the pinion gear that is mounted on the drive shaft. When the drive shaft rotates, the pinion gear rotates, which in turn rotates the crown gear and the driven shaft.

One advantage of using a crown gear is that it provides a high gear ratio in a compact package. The large diameter of the crown gear allows for a greater number of teeth, which results in a higher gear ratio and smoother operation. Additionally, the teeth of a crown gear are engaged over a greater surface area, which results in a stronger and more durable gear system.


How To Maintain The Crown Gear?

Here are some maintenance tips for crown gears:

Inspect the gears regularly: Inspect the gears regularly for signs of wear and tear. Look for cracks, chips, or missing teeth. If you see any damage, replace the gear as soon as possible.

Lubricate the gears regularly: Crown gears should be lubricated regularly to prevent wear and tear. The type of lubricant you use will depend on the application. In general, you should use a lubricant that is compatible with the materials the gears are made of.

Keep the gears clean: Keep the gears clean to prevent dirt and debris from building up. This can cause the gears to wear out prematurely. You can clean the gears with a mild solvent or soap and water.

Avoid overloading the gears: Overloading the gears can cause them to wear out prematurely. Make sure that the gears are not being overloaded by the application.


Crown Gear Advantage

Smoother operation

Smoother operation

Crown gears have a smoother operating profile than other types of gears, which reduces vibration and noise. This makes them ideal for applications where noise and vibration are a concern, such as in medical equipment or in high-precision machinery.

Greater efficiency

Greater efficiency

 Crown gears are more efficient than other types of gears, which means that they can transmit more power with less energy loss. This makes them a good choice for applications where efficiency is important, such as in electric motors or in industrial machinery.

Increased load capacity

Increased load capacity

Crown gears can support higher loads than other types of gears, which makes them a good choice for applications where heavy loads are present, such as in mining or construction equipment.
