Planetary gear reducer mainly consists of planetary wheel, sun wheel, inner ring three parts, its structure is precise and compact and high transmission efficiency, often installed in servo motors, used to reduce the speed, increase the torque, relying on the low backlash design to achieve high-precision positioning. Widely used in CNC machine tools, industrial robots, service robots, robots, food machinery, packaging machinery, laser cutting machines, wood engraving machines, printing machinery, injection molding machinery, photovoltaic equipment, lithium equipment and other automation equipment.
It is reported that the miniaturization of machinery and equipment, lightweight has been the trend, how to balance the product performance and quality and low-cost and efficient production, is all equipment manufacturers must pay attention to the problem. Our precision planetary gearheads significantly improve space utilization by optimizing the layout of internal gears and bearings. With the same output performance, their volume and weight are usually smaller than traditional gearheads, effectively saving space in equipment.
With their compact design, our planetary gearheads excel in key performance indicators:
1. High Rigidity & Load Equalization Design: Precision gear sets evenly distribute the load to multiple planetary wheels under close meshing, significantly increasing the load carrying capacity (rated output torque range up to 19Nm to 2000Nm).
2. High transmission efficiency: Gear sets work in optimized close mesh, significantly reducing friction losses. The efficiency of single-stage transmission usually reaches >97%, which is much better than the 93-94% of general gear transmission, effectively improving the efficiency of the whole machine and reducing energy loss.
3. High precision & low backlash: Provide a variety of backlash levels to choose from (e.g. Standard Backlash (P2) <5 arcmin, Precise Backlash (P1) <3 arcmin, Ultraprecise Backlash (P0) <1 arcmin), to meet the stringent requirements of different application scenarios in terms of positioning accuracy and repeatability.to meet the stringent requirements of different applications for positioning accuracy and repeatability.
4.Wide range of reduction ratios: Wide range of reduction ratios from 3:1 to 100:1 (single-stage commonly used 3:1-10:1, multi-stage combinations can be higher), providing flexible speed ratio options.
5. Low noise & high reliability: Optimized meshing and high-precision machining ensure smooth operation, low noise (usually <65dB) and long life.
6. High protection level: standard protection level can reach IP65, adapting to the more severe industrial environment.
In addition, the efficiency loss of the gearbox during the transmission process directly affects the energy consumption of the equipment. The high efficiency design of our planetary gearboxes (single stage >97%) ensures that kinetic energy loss is minimized from the input of the servo motor to the output of the mechanical end, avoiding significant power loss due to frictional sliding of the internal gears, thus significantly increasing the efficiency and energy utilization of mechanical equipment.
As the demand for industrial robots and precision automation equipment continues to grow due to the transformation and upgrading of global manufacturing automation, high-performance, compact planetary gearboxes will usher in a broader market space.
