Employing the right angle planetary gearbox, the motor speed can be effectively regulated even when applied to tasks involving high-speed rotation. However, the compact designs of the gearing including the rolling as well as the sliding surfaces should be ideally lubricated in order to lengthen the tool life and ensure the smooth speed reduction operation.
The right angle planetary gearbox is a compact and efficient type of gear reducer that combines the advantages of the right angle type of gearbox and the planetary gearbox mechanism. Similar to other types of gear reducer, the functions of the mechanical gadget are to regulate and decrease the input speed of the servo motor, while raising the torque and correct output speed through the speed reduction cycles.
The conventional planetary gearbox reducer is widely known as the inline planetary gearbox that has the input shaft and the output shaft aligned, decreasing the input speed effectively and offering a relatively high torque for the machine system. The production of the right angle planetary employs the compact right-angle structure, where the output shaft and the drive shaft meet at a 90° angle. The right-angle planetary gearbox has flexible mounting options, offering smart drive solutions within a compact design. The output shaft mentioned here provides the right angle gear reducer the benefit of a dependable transmission of high torque and proper speed.
In addition to this advanced type of gear reducer for servo motors, there are a broad variety of other forms and styles of motor speed reducer, the gearbox form like the planetary gearbox is the most classic and popular one. Gear reducers, including right angle planetary gearboxes, are invaluable solutions since the appropriate output speed as well as the torque density can define the operating speed, the consistent performance of the moving components in various machine tools, extending the available work.
Employing the right angle planetary gearbox, the motor speed can be effectively regulated even when applied to tasks involving high-speed rotation. However, the compact designs of the gearing including the rolling as well as the sliding surfaces should be ideally lubricated in order to lengthen the tool life and ensure the smooth speed reduction operation. The common lubricants used in a right-angle planetary gearbox include oil, grease, and synthetic gel. The lubrication mentioned here can not only ensure the normal performance of the gears but also can reduce the vibration noise during the operations and cool down the units.
The right angle planetary gearboxes rely on the mechanism of the planetary gearbox.
The basic structure of the planetary gear basically consists of a "sun gear" that is mounted at the center, an outer ring, the planetary gears around the sun gears, and also a carrier.
The outer ring is commonly called the internal gear because the teeth of the gear face inward. In the arrangement, the planetary gears mesh with the sun gear as well as the stationary ring. The planetary gears are held and spaced properly by the carrier in order to revolve around the central sun gear. As the sun gear receives the input, the gear as well as the planetary gears surrounding it rotate on the axes, and the carrier also incorporates with the output shaft at the moment. Since the gears have different numbers of gear teeth, during the speed reduction, the output gear can spin slower and supply an ideal amount of torque for the machine system.

When it comes to the right angle gearbox design, it is one family of gear reducers that are produced with the driveshaft and the output shaft meets at a 90° angle, completing power transmission under consistent rotation. They can also support the power transmission jobs at different angles. Although it is called a “right angle” gearbox, the speed reducer family can run at right angles to one another, spinning to the right and also available to the left. The axes of the right angle gear reducer can intersect in a single plane or cross on 2 planes that are parallel to each other, and this depends on the specific type and design.
The right angle gearbox reducer comes in a wide variety of gear teeth designs and combinations of different gearings within the construction. Among them, the bevel gearboxes and the worm gearboxes are the two most popular and common single-stage speed reducers today. With the worm gear reducer, the system can achieve a self-locking operation with higher single-stage reduction ratios but less efficiency.
As for the bevel gearbox, it also consists of various gearing. The structure of bevel gears includes the axes of the two shafts which intersect with each other, and gears’ tooth-bearing faces are conically shaped. Many bevel gear reducers employ the straight, helical, or spiral teeth design. A popular modern application in this right angle gearbox is the combination of bevel gear and the planetary gearbox, as a result, the planetary gear reducer can be attached upstream or downstream. The combination of planetary gear mechanism and the right-angle structure design upgrade the overall flexibility in both the usage in numerous industrial applications and also much more mounting options in the machine system to fit the special requirements.
For starters, the right angle planetary gearboxes bring both the benefits of the conventional planet-wheel mechanism and also the right angle gearboxes’ advantages. The compact, advanced gearbox with an output shaft can best suit a wide range of performance classes and usage. The gear reducer provides a low backlash operation with high precision in positioning especially when in the reverse mode.
As mentioned, the right angle planetary gearbox offers more mounting options, which can be integrated into various systems with different kinds of connection units, utilizing a threaded or through-hole. The lubrication is also upgraded to a life system that ensures the freedom of the operator to mount the drive and install the gearboxes at the desired position.
