Product advantages:
1. High Precision and Low Backlash
The PL40 gearbox is designed with hardened spur gears optimized through advanced 3D simulation technology. All gears are precision-ground to achieve low backlash, with a range of <12 - <18 arcmin. This ensures highly accurate motion control and positioning, making it suitable for applications requiring precise transmission.
2. High Torque Capacity and Compact Design
Despite its small frame size of 40mm, the PL40 high speed precision gearbox offers a nominal output torque range of 12-18 Nm. It is also designed to handle maximum radial and axial forces of 220 N and 200 N, respectively. This compact yet powerful design makes it ideal for space-constrained applications while still delivering high performance.
3. High Efficiency and Low Noise
The PL40 gearbox operates with an efficiency of 92%-97% at full load, ensuring minimal energy loss and high power transmission efficiency. Additionally, it produces low running noise, below 58 dB, which is crucial for applications where quiet operation is required.
4. Wide Range of Gear Ratios and Customization
The PL40 gearbox offers multiple gear ratio options, including single-stage ratios of 3, 4, 5, 6, 8, and 10, as well as two-stage and three-stage ratios up to 512. This flexibility allows for customization to meet specific application needs, whether for high-speed or high-torque requirements.
5. Durability and Long Service Life
The high speed precision motor is built with high-quality materials and optimized designs to withstand heavy loads and demanding operating conditions. It features a long service life of up to 20,000 hours and is designed for low maintenance, with grease lubrication that eliminates the need for frequent servicing.
