Customized Double Helical Pinion Gear for Gearbox and Gear Transmission Machine

Product Description


Double Helical Gear

A Double Helical Gear is another name for a herringbone gear (a side by side combination of 2 helical gears of opposite hands).

Double Helical Pinion

A Double Helical Pinion (or a herringbone pinion) is a cylinder with external involute radial teeth that spiral around the circumference from each end to meet angles forming a “v” in the center. The most popular helix angle is 30 in a Double helical pinion. Often there is a groove between the 2 sets of teeth. Double helical and herringbone are 2 names for the same type of gear. Herringbone usually refers to a gear or pinion with a 30 helix angle with a minimal groove between the sets of teeth (usually about 1/2″ or so) or no groove at all. Double helical usually refers to a gear with a very wide groove between the 2 sets of teeth (maybe 2″ or 4″ or even more) and usually with some other helix angle other than 30 (often an odd helix angle (not an even angle) like ″ or whatever). Double helical pinion can be made from customer-supplied materials, as well as materials provided by CHINAMFG Metallurgy Manufacturing .

crown gear

What is the role of a crown gear in power transmission?

A crown gear plays a crucial role in power transmission within a mechanical system. Let’s explore the role of a crown gear in power transmission:

  • Power Distribution:

Crown gears are used to transfer power between two intersecting shafts. When a crown gear meshes with other gears in a system, it enables the transmission of rotational energy from the input shaft to the output shaft. This power distribution mechanism allows the system to efficiently transfer and control the flow of mechanical energy.

  • Torque Transmission:

One of the primary functions of a crown gear is to transmit torque. Torque refers to the rotational force applied to an object. When the input shaft rotates, the crown gear engages with other gears, and through the interaction of their teeth, torque is transmitted from the input shaft to the output shaft. Crown gears are designed to handle high torque loads, ensuring effective power transmission within the system.

  • Speed Reduction or Increase:

In addition to power distribution and torque transmission, crown gears also contribute to speed reduction or increase in a system. By meshing with gears of different sizes or gear ratios, the rotational speed of the output shaft can be adjusted relative to the input shaft. When the crown gear engages with a smaller gear, it results in speed reduction, providing higher torque output. Conversely, when it meshes with a larger gear, it leads to speed increase, sacrificing torque for higher rotational speed.

  • Directional Change:

Crown gears can also facilitate a change in rotational direction within a power transmission system. By meshing with other gears, they can redirect the rotational motion from one shaft to another shaft oriented at a different angle. This ability to change the direction of power transmission allows for the efficient transfer of rotational energy in systems with complex configurations.

  • Efficiency and Load Distribution:

Crown gears are designed to optimize power transmission efficiency. Their tooth profile and engagement properties minimize energy losses due to friction, ensuring efficient transfer of mechanical energy. Additionally, crown gears distribute the load evenly across their teeth, reducing stress concentrations and promoting longevity and reliability in the system. By efficiently transmitting power and evenly distributing loads, crown gears contribute to the overall performance and durability of the power transmission system.

In summary, the role of a crown gear in power transmission involves power distribution, torque transmission, speed adjustment, directional change, and the promotion of efficiency and load distribution. Crown gears are essential components that enable the controlled transfer of mechanical energy, allowing for effective operation and performance of various mechanical systems.

How does a crown gear handle variations in load and stress conditions?

A crown gear is designed to handle variations in load and stress conditions by employing specific features and characteristics. Let’s explore how a crown gear handles these variations:

  • Large Contact Area:

Crown gears have a relatively large contact area compared to other gear types. This increased contact area allows for better load distribution across the gear teeth during meshing. As a result, the load on each tooth is reduced, minimizing localized stress concentrations and enhancing the overall load-carrying capacity of the gear.

  • Perpendicular Tooth Orientation:

Crown gears have teeth that are oriented perpendicular to the gear axis. This orientation helps distribute the load more evenly across the gear teeth. When the gear meshes with another gear, the perpendicular tooth alignment allows for a greater number of teeth in contact at any given moment, spreading the load and reducing the stress on individual teeth.

  • Curved Tooth Profile:

The curved tooth profile of a crown gear contributes to its ability to handle variations in load and stress conditions. The curved shape allows for gradual contact and engagement with other gears, reducing sudden impacts and minimizing stress concentrations. This design feature helps absorb and distribute the load more evenly, enhancing the gear’s resistance to variations in load and stress.

  • High Strength and Durability:

Crown gears are typically manufactured using materials with high strength and durability, such as hardened steel or alloy steels. These materials provide the necessary mechanical properties to withstand varying loads and stress conditions. With proper material selection and heat treatment, crown gears can resist wear, fatigue, and deformation, ensuring reliable performance under different operating conditions.

  • Load Sharing in Gear Systems:

In gear systems, multiple gears work together to transmit power and handle the applied loads. Crown gears play a role in load sharing within the system, distributing the load between multiple gears. By distributing the load across several gears, each gear experiences a reduced load, minimizing the stress on individual gears and enhancing the overall system’s ability to handle variations in load and stress conditions.

In summary, crown gears handle variations in load and stress conditions through their large contact area, perpendicular tooth orientation, curved tooth profile, high strength and durability, and load-sharing capabilities in gear systems. These design features and characteristics enable crown gears to distribute loads more evenly, reduce stress concentrations, and enhance the gear’s ability to handle varying operating conditions, ensuring reliable and efficient power transmission in a wide range of applications.

How does a crown gear differ from other types of gears?

A crown gear, also known as a contrate gear or a contrate wheel, has distinct characteristics that set it apart from other types of gears. Let’s explore the key differences between a crown gear and other gears:

  • Tooth Orientation:

One of the primary differences is the tooth orientation. In a crown gear, the teeth are positioned perpendicular to the gear’s face. This is in contrast to other gears, such as spur gears or bevel gears, where the teeth are parallel or at an angle to the gear’s axis. The perpendicular tooth arrangement of a crown gear allows for specific functionalities in mechanical systems.

  • Directional Change:

A significant advantage of crown gears is their ability to change the direction of rotation in a mechanical system. By meshing with other gears, crown gears can redirect rotational motion by 90 degrees. This directional change capability is particularly useful in applications where a change in motion direction is required, such as conveyors, cranes, and other machinery.

  • Meshing with Different Gear Types:

Crown gears can mesh with gears that have parallel axes or bevel gears with intersecting axes. This versatility allows crown gears to work in conjunction with other gear types, enabling torque and rotational motion transfer between them. The perpendicular tooth orientation of crown gears facilitates smooth meshing with these different gear configurations.

  • Force Distribution:

Another distinguishing feature of crown gears is their ability to distribute forces and torques in mechanical systems. By meshing a crown gear with other gears, the load can be spread across a larger contact area. This distribution of forces helps reduce stress and wear on individual gear teeth, promoting smoother operation and improved durability of the gear system.

  • Applications:

Crown gears find applications in various industries due to their unique characteristics. They are commonly used in steering mechanisms, such as rack and pinion systems in automotive applications, where the crown gear meshes with a rack to convert rotational motion into linear motion for precise steering control. Crown gears are also employed in automation and robotics for motion control mechanisms, enabling changes in motion direction and force distribution in robotic arms, gantry systems, and other automated equipment.

In summary, a crown gear differs from other types of gears primarily in its tooth orientation, ability to change motion direction, versatility in meshing with different gear types, and force distribution capabilities. These distinctions make crown gears suitable for specific applications where directional change, force distribution, and precise motion control are required.
