1. RV reducer: "tough guy" for heavy load and impact resistance
The RV reducer combines a planetary gear and a cycloidal pinwheel structure and has high rigidity, large torque, high precision and strong resistance to overload impact.
RV suitable palletizing equipment:
Heavy-duty palletizing robot: Dedicated to heavy-load joints such as the base (waist) and big arm of the palletizing robot"s robotic arm, which can withstand the weight of the goods and the inertial force of the robotic arm itself.
Heavy-duty palletizing equipment: such as heavy-duty palletizing machines with a load of ≥200kg, or intelligent robot palletizing systems used to transport heavy materials such as bags of cement.
RVSelection pit avoidance tips:
Accuracy matching: For high-precision stacking scenarios such as electronics and medicine, it is necessary to give priority to high-precision series (such as hysteresis ≤ 0.5 arcmin); if it is only for general overload scenarios, choose conventional series. Blindly pursuing high accuracy will significantly increase costs.
Torque margin: When calculating the rated torque, a safety margin of 20%-30% must be reserved to cope with frequent starts and stops and dynamic loads during the palletizing process.
2. Cycloidal reducer: an "all-rounder" with high-frequency start-stop and impact resistance
Cycloidal reducers (including precision cycloidal reducers) rely on multi-tooth synchronous meshing transmission, which has smooth operation, strong impact resistance, and the transmission efficiency can usually reach more than 90%.
Cycloid is suitable for palletizing equipment:
High-level palletizer: It is often used for the lifting or conveying drive of high-level palletizer. With the servo motor, it can realize high-frequency palletizing operations (for example, the palletizing speed can reach 2000 bags/hour).
Traditional/universal palletizer: suitable for packaging and palletizing lines that require frequent starts and stops and multi-axis coordination, and can well adapt to continuous heavy-load and impact-resistant working conditions.
Cycloid Selection pit avoidance tips:
Safety factor: When Selection, be sure to leave a safety factor of 1.2-1.5 times the rated torque, and the actual load is controlled within 80% of the rated torque to extend the service life.
Noise and heat: Inferior cycloidal reducers are prone to problems such as loud noise and severe heat. Precision-grade products should be selected (return gap ≤ 5 arc minutes), and synthetic high-temperature resistant lubricants should be used.
3. Planetary reducer: an economical and practical "all-rounder"
Planetary reducers have compact structure, high transmission efficiency (generally above 95%), and high cost performance, but their rigidity and accuracy under extreme heavy loads are slightly inferior to RV reducers.
Planetary palletizing equipment:
Light/medium palletizer: Suitable for light palletizers with loads ≤50kg, or wrist joints of collaborative palletizing robots.
AGV/stacker traveling mechanism: It is commonly used in the horizontal traveling drive or lifting mechanism of stackers and AGV trolleys in automated warehousing systems to meet the needs of high-precision positioning and frequent reciprocating movements.
