Recently, a welding robot manufacturer in Shenzhen stated, "Welding robots require highly precise positioning motion of the welding gun during welding, as well as high torque output. Therefore, we need to use high-precision and rigid cycloidal gearboxes in the development of welding robots."
1) The crucial rule for ensuring the accuracy of the welding pool
During the customer engagement process, the Chief Engineer of the welding robot factory expressed, "Modern robotic welding equipment must be able to work quickly and accurately. This speed and accuracy extend not only to the welding robot itself but also to the rapid and precise positioning motion of the welding gun and torch. Therefore, the gearbox that provides power to the welding gun and torch should not only be compact in structure but also have a high load-bearing torque capacity." For this reason, the manufacturer selected the WF Series precision cycloidal gearbox developed by Dongguan Weitengstan for their welding robots.
After a period of use, the factory manager reported, "By using this precision cycloidal gearbox in the positioning motion system of our welding robots, we can achieve precise positioning within a range of 0.1mm without releasing or re-clamping the workpiece. This is crucial for ensuring the accuracy of the welding pool. The minimal backlash, high impact resistance, and compact structure of the WF Series precision cycloidal gearbox provided by Dongguan FUBAO convinced us to choose this gearbox, and the results have proven our decision to be correct."
Customer recognition is our greatest motivation! Why did Dongguan Weitengstan's cycloidal gearbox gain such recognition from this customer?
2) Let's analyze it together
It is well-known that all gearboxes have reduction losses, but the reduction losses of precision cycloidal gearboxes are extremely small, reaching more than 9.5 times (compared to ordinary gearboxes at 6-7 times). Therefore, they have very high transmission efficiency, long service life, and minimal backlash (backlash ≤ 1 arc minute). All power transmission components are based on rolling friction, ensuring an ultra-low starting torque for this precision cycloidal gearbox.
The precision cycloidal gearboxes developed and produced by Dongguan FUBAO have applied for 18 invention patents, including 6 international PCT invention patents. They adopt a new reduction principle and newly developed radial and axial output bearings to reduce vibration and inertia moments, allowing for higher speed ratios. Due to the nearly 50% synchronous meshing of the cycloidal gears, the cycloidal gearbox has minimal backlash and high load-bearing capacity when transmitting power uniformly.
With this unique structural design, our cycloidal gearbox series products possess high motion repeatability and stable trajectory performance. The symmetrical structure and support of rolling bearings on each axis ensure the stable operation of the cycloidal gearbox throughout its entire service life, allowing it to withstand peak loads up to five times the rated torque.
In conclusion, the WF Series cycloidal gearbox demonstrates significant advantages, making it highly favored by users!
