To offer you the best possible ordering convenience, our planetary gearbox series are now available online. The high-end economy series with the shopping cart symbol can be ordered directly in the online shop. The high-end series with the letter symbol are available on request (see legend).


The high-end range includes the gearbox lines GSD (flange gear), GSB (inline) and GSBL (angle gear). All three lines are equipped with precision ground helical gearing, single-piece planetary carriers and full needle bearings. The housings are designed from a one-piece, robust housing. This improves the gear rigidity and enables the absorption of higher loads. The sun pinions are fitted with an additional bearing system in order to ensure quieter operating behavior. The 2-stage versions are constructed in a space-optimized design. Due to the lower torque values, the input stage is dimensionally smaller than the output stage.


The high-end economy lines GSN and GFE are equipped with ground, helical-cut precision components, which ensure low operating noise, very quiet operating characteristics and above-average torque absorption. Both lines have a full needle bearing, which has been especially designed for high torques. The planetary carriers are manufactured as a cage made from solid material. This increases quiet operating characteristics while at the same time improving positioning accuracy and reducing backlash.


In the design of your customized planetary gear, you will benefit from our expertise in gear technology, our know-how in combination with tried-and-tested materials, as well as our decades-long experience in developing customer-specific drive solutions. We would be glad to speak with you. Contact us directly with any wishes or requests or via inquiry form.


Demonstrate the essence of planetary gears with a tabletop model that you built yourself. This STEAM project is a great challenge for detail-oriented, advanced hobbyists while doubling as a great learning tool to show how gears work.


A gear reducer is a mechanical transmission device that connects a motor to a driven load. It is also known as a gearbox. It allows you to modify the torque and speed between a motor and a load. Reduction gear assemblies are made up of series of gears. The gear reduction ratio (the ratio of the number of teeth between input and output shafts) is also known as the transmission ratio.


It is therefore appropriate to ask yourself about the torque first and foremost. A reducer increases the torque of your motor and thus allows a receiving member to rotate under the impact of a new torque. Gear reducer manufacturers sometimes indicate the minimum and maximum torque (expressed in newton meters, N.m) that can be supported by each of their products. The torque density varies according to the gear reducer. For example, planetary gearboxes have a high torque density.


The other purpose of a gear reducer is to reduce the motor speed and we recommend that you take into account the ideal reduction ratio for your use. Based on the rotational speed of your motor, the reduction ratio is used to determine the output rotational speed. This information is also indicated by manufacturers on their product pages. It is given in revolutions per minute.


Lastly, you should ask yourself what kind of gear reducer assembly is most appropriate for your application. The input and output shafts of your gear reducer can be coaxial, parallel-shaft or orthogonal. This depends on your intended use.


The advantages of planetary gearboxes include their compact size, high efficiency, low clearance and high torque to weight ratio. On the other hand, their complex and costly design requires specialized maintenance.


We recommend the use of a planetary gearboxes for applications requiring strong accelerations (robotics) as well as for applications with a slow speed but high torque (industrial rotary furnaces). They are also widely used for machining centers and other machine tools, and mobile machinery used in public and agricultural works.


The mechanism of worm gear reducers is non-reversible. This means that the worm wheel cannot drive the worm. The advantage of this non-reversible mechanism is that it ensures a greater level of security for the system.


However, like planetary gearboxes, worm gear reducers heat up quickly due to how compact they are. They also have a variable performance level. You can however improve the performance by combining your worm gear reducer with other gearboxes and gear trains.


Bevel gear reducers are compact. They are also robust and can handle a lot of power. As such, if you need a high torque we recommend that you choose this technology. The robustness of their teeth allows you to use them with three-phase asynchronous motors, or synchronous or asynchronous servomotors.


Bevel gear reducers are quiet, making using them pleasant to use. Additionally, they offer a high performance level and are energy efficient. Their performance level remains lower than planetary gearboxes however. Bevel gear reducers are also very expensive and require difficult maintenance.


If a gear reducer has an orthogonal shaft orientation, the input and output shafts are perpendicular. This is often the case for bevel gear reducers and worm gear reducers. Orthogonal shaft orientation is also used in industrial installations and differential automotive bridges.


If a gear reducer has a coaxial shaft orientation, the input and output shafts are aligned. This is the case, for example, for planetary gearboxes or gear reducers used in engines and turboprop engines used in the aeronautic industry.


Magnetic gear reducers can advantageously replace conventional gear reducers to ensure speed and torque multiplication by using magnetic attraction instead of physical contact between moving parts. To date, complex assemblies, high weight and low torque have slowed the diffusion of this magnetic technology.


However, magnetic gears eliminate the need for lubrication and therefore minimize maintenance costs. No lubrication also means that mechanisms can operate at extreme temperatures (currently tested from -200C to 350C).


Zyltech Nema17 Stepper Motor w/ planetary gearbox features high torque, low driving voltage, and minimal heat gain, making it perfect for continuous operation in 3D printers, laser engravers, CNC routers, etc.


The UltraPlanetary System is a cartridge based modular gearbox designed to handle the rigors of the competition and the classroom. The UltraPlanetary System includes an input stage and pinion gear that works the REV HD Hex Motor and other 550 class motors. Building on the ability to iterate and adjust designs easily using the REV Building System, the UltraPlanetary System consists of pre-assembled and lubricated cartridges allowing for swapping gear ratios on the fly and with ease. Users can configure a single-stage planetary using one of three different reduction cartridges, build multi-stage gearboxes through stacking individual cartridges together, and choose two different ways for transferring power: either through face mounting directly on the output stage or choosing the length of 5mm hex shaft best suited for the application.


The UltraPlanetary has a variety of options for mounting with four different brackets available for mounting to REV 15mm Extrusion, REV C Channel, or REV U Channel. The UltraPlanetary 550 Motor Pinion Gear (REV-41-1608) included in this kit is pressed on to an HD Hex Motor (REV-41-1291). Additional pinion gears can be purchased on the 550 Motor Pinion product page.


When considering the convenience of the user, there are a variety of types of stocked gears including spur gears, bevel gears, helical gears, worm gears, and racks as well as a wide variety of needs such as the pitch of gear teeth, the size of gears, materials such as metal or plastic, gear grades (ISO, JIS, DIN, AGMA, etc.), whether teeth face are polished, and whether the gears are tempered.


Among spur gears, there exist wide variations in terms of the number of teeth, module (pitch of the teeth), accuracy depending on the use of teeth grinding, hardness depending on quenching, material, with or without shaft, method of shaft fastening, etc.


There are wide variations among helical gears in terms of helix angle, twisting direction, reference cross section of gear, etc. Just like spur gears, there are wide variations in terms of number of teeth, module, material, presence or absence of polishing and quenching.


Internal gears are the gears which have their teeth inside cylinders or cones and are frequently used in planetary gear mechanisms. The internal gear always meshes with an external gear where the internal gear is always the large gear while the external gear is the pinion. In these cases, involute interferences, trochoid interferences, or triming may occur depending on the number of teeth of the meshing gears.


Gear racks are rod-like gears used to turn rotating motion into linear motion, and can be considered as large gears with pitch cylinders of infinite radii. The gear racks are used for machine tools and steering systems of automobiles. Helical racks are gear racks whose tooth traces are diagonal.


Miter gears are a type of bevel gears composed of a pair of bevel gears with the same number of teeth and a pitch surface angle of 45. Just as in bevel gears, there are straight miter gears with straight tooth traces and spiral miter gears with twisted tooth traces. In addition, there are special miter gears called angular miter gears whose shaft angles are not 90 degrees. 041b061a72
