Planetary Gear (Epicyclic Gear)
A planetary gearbox has two distinct parts: a central sun gear and a ring gear with internal teeth that are concentric with the sun gear. They are often used in a variety of applications, including automotive transmissions, off-road motors, and industrial conveying systems.
Planetary Gear for Sale
Planetary gear, also referred to epicyclic gear, is a kind of transmission that makes use of an array of gears in circular meshes in order to transfer motion. This gearing system was specifically designed to decrease the effort of driving and enhance the level of comfort. The planetary gear set are often employed in hybrid vehicles and automatic transmissions. A planetary gearbox is comprised of two distinct components that include an axial sun gear, and a ring with inner teeth which are in concentric on the sun gear. These components are mounted on an earth carrier. A planet differential is set up to allow for unbalanced ratios or multiple input/output configurations. As a planetary gear manufacturer, factory and supplier in China, we have different types of planetary gear sets for sale.
Planetary Gear Types
Planetary gears are one type of transmission that divides the burden among at least two gears. This type of system has a great level of stiffness and a homogeneous mass distribution, which means it is very reliable. Planetary gears can also be equipped with the idler. They are commonly employed in the planetary gear set and are typically used in industrial machines.
It is employed to drive different machines due to its efficiency, small size, transmission ratio as well as its an excellent power-to-weight ratio. Different types of planetary gears comprise spur gears and single helical gears as well as herringbone gears. Herringbone gears are planetary and is more powerful in carrying loads and has less axial force. it is often used for heavy equipment.
Epicyclic reduction gear sets are utilized when weight and space are crucial and a significant amount reduced speed is needed. They are commonly employed in construction equipment and tractor models that require large power to propel wheels. They can also be found in electric screwdrivers, electronic transmissions and turbine engines. They are also utilized in industrial, agricultural and forestry applications.
As a rule the planetary gearbox is highly efficient and is able to transmit 97% of power input. Apart from being extremely efficient, it also has the ability to minimize vibration and noise.
What is a Planetary Gear Used For?
A planetary gear is a gear that transmits torque by sharing the load across multiple gear teeth. The epicyclic gear drive is suitable for applications with frequent changes in direction of rotation, such as those involving fast start-stop cycles. These planetary gears are also known for their high stiffness and low tooth clearance, making them ideal for frequent operations.
Planetary gears are used in many industries, including construction equipment. They are also used in automatic transmissions, electric screwdrivers and turbine engines. These planetary gears can be small enough to fit in tight places, yet large enough to transmit large amounts of torque. They are also suitable for bicycle speed change mechanisms.
The simplest planetary gear set consists of a sun wheel and two or more planetary gears. These epicyclic gears are kept in constant mesh by a common carrier. Ring components and pinions are then attached to the carrier.
Key Benefits of Planetary Geared Motors
Improved repeatability: Its higher speed radial and axial loads provide reliability and robustness, minimizing gear misalignments. In addition, uniform transmission under different loads and low vibration provide perfect repeatability.
Perfect precision: stability of most rotation angles improves the accuracy and reliability of the movement.
Lower noise level because there is more surface contact. Rolling is much softer and jumps are almost non-existent.
More durability: due to its torsional rigidity and better rollability. To improve this feature, your bearings help to reduce the losses that would be generated by rubbing the shaft directly on the case. As a result, a higher efficiency and smoother operation of the gears is achieved.
Very good efficiency levels: planetary gearboxes offer higher efficiency and, thanks to their design and internal layout, minimize losses during operation. In fact, today, this type of drive mechanism offers higher efficiency.
Increased torque transmission: With more teeth in contact, the mechanism is able to transmit and withstand greater torque. In addition, it does so in a more uniform manner.
Maximum versatility: Its mechanism is contained in a cylindrical gearbox that can be installed in almost any space.
