What is Planetary Gearboxes?
A Planetary gear reducer is a gearbox in which the input and output shafts are aligned. Planetary gearboxes are used to transmit maximum torque (called torque density) in the most compact form. Planetary reducers are mostly used in industries such as robotics, 3D printing, new transportation, and other fields.
A planetary reducer is a kind of speed reduction device widely used in mechanical transmission system. It consists of planetary wheel, sun wheel, internal gear, external gear, ring gear and planetary shaft. Planetary reducer has the advantages of small size, lightweight, high transmission precision, smooth torque output low noise, etc. It is widely used in machine tools, automation equipment, packaging machinery, plastic machinery, printing machinery, air compressors, food machinery, textile printing and dyeing machinery and many other fields.

FAQ
Q: What is a planetary gearbox?
A: planetary gear reducer is a speed reduction device based on a planetary wheel structure, suitable for applications that require speed reduction and at the same time are capable of carrying high torque. It usually consists of three parts: a planetary wheel, a sun wheel, and an internal gear, and the speed reduction is achieved by the combination of the rotation of the three wheels.
Q: What are the advantages of planetary gearboxes?
A: Planetary gear reducer has the advantages of compact structure, strong load carrying capacity, high reduction ratio, high efficiency, smooth operation, low noise and so on. In addition, it has a long service life, relatively simple maintenance, and has a high cost performance.
Q: What are the common planetary gearbox applications?
A: Planetary reducers are widely used in industrial production, machinery manufacturing, aerospace, military defence and other fields, especially in the need for high-torque transmission occasions, such as lifting equipment, metallurgy and iron and steel, mining machinery, cement equipment and other fields have been widely used.
Q: What are the core components of a planetary gearbox?
A: A planetary gearbox primarily consists of core components such as the sun gear, planetary gears, an internal ring gear, and a planetary carrier. The sun gear drives the planetary gears, which rotate around it and simultaneously roll along the internal ring gear, achieving both power transmission and speed reduction. This structure is key to its high torque density and compact design.
Q: What series of planetary gearboxes does Hansheng Automation offer?
A: We offer a full range of planetary gearboxes, including the PGL, PGH, PGR, PGHR, PGF, PGFR, and PGE series.
Q: The product mentions "high-precision backlash less than 3cm." What does this parameter actually mean?
A: Backlash is the clearance between gears when meshing, which directly affects positioning accuracy. For example, the smaller the backlash, the less "lost travel" during reverse motion. This makes it suitable for applications requiring frequent forward and reverse rotation or high-precision positioning (such as robotic joints and 3D printing equipment). Hansheng planetary gearboxes utilize helical gears to further optimize meshing accuracy and ensure smooth operation.
Q: How to choose the right planetary gearbox model?
A: Selection requires consideration of the following key parameters:
Reduction ratio: Adjust according to the required speed of the equipment (input speed / reduction ratio = output speed);
Rated torque: Match the equipment load; a 20%-30% safety margin is recommended;
Backlash: For high-precision applications (such as CNC machining), select ≤3 arc minutes; a lower limit can be applied for general industrial applications;
Mounting dimensions: Confirm the compatibility of flanges, shaft diameters, and other factors with the motor and equipment.
Q: Can you provide customized services? For example, special reduction ratios or interface designs.
A: Customized services are available, including:
Non-standard reduction ratios (such as customer-specific 1:15, 1:40, etc.);
Customized flanges, shaft diameters, and other mounting interfaces to accommodate specific motors or equipment;
Upgraded protection levels (such as IP65) for harsh environments such as high temperatures and dust. Customization typically takes 7-15 business days. Please contact our technical team for details.
Q: What is the product warranty policy?
A: Hansheng planetary gearboxes come with a 20-month warranty. During the warranty period, we provide free repair or replacement of parts for non-human damage.
