Key points for selecting lightweight and high-precision reducers for new energy equipment
The selection of reducers in new energy equipment (such as wind power, photovoltaics, new energy vehicles, etc.) directly affects the operational efficiency, stability, and service life of the system. In response to the two core demands of "lightweight" and "high precision", the following key points should be focused on when selecting:
1、 Key points for lightweight design selection
Lightweight technology can help reduce the overall energy consumption of new energy equipment and improve dynamic response performance, mainly achieved through structural optimization and material innovation
Advanced materials and topology optimization: Prioritizing the use of aluminum magnesium alloy shells instead of traditional cast iron can achieve significant weight reduction; The internal planetary carrier can be designed with hollow or biomimetic structures (excavating non stress areas) to significantly reduce weight while ensuring fatigue life. In cutting-edge applications, carbon fiber composite planetary carriers or 3D printing technology can also be considered to further enhance power density.
High torque density index: Lightweight cannot be achieved at the expense of bearing capacity. The unit weight torque value of high-quality lightweight planetary gearboxes should reach a high standard (such as ≥ 150N · m/kg) to ensure that they can still output high torque in a compact volume.
Integrated and modular layout: It is recommended to choose a solution that integrates the design of components such as motors, reducers, and differentials (such as a three in one electric drive system). This not only effectively reduces volume and weight, but also lowers manufacturing costs.
2、 Key points for selecting high-precision control models
High precision is the key to ensuring the precise execution of actions by new energy equipment, such as chasing light, pitch control, and robotic arm grasping
Strict return clearance (backlash): In precision scenarios, backlash must be strictly controlled. Conventional high-precision requirements are ≤ 1 arc minute. For extreme precision requirements (such as medical CT, aerospace deployment mechanisms, or robot joints), customized products with a backlash of ≤ 0.5 arc minute should be selected.
Micro level positioning and low noise: High precision transmission often comes with extremely low operating noise (such as controlled within 50dB) to avoid interfering with the accuracy of sensors inside the equipment. At the same time, the meshing accuracy of the gears needs to meet the requirements of micrometer level repeated positioning (such as ± 0.01mm level).
High rigidity and impact resistance design: In order to prevent positioning sinking or deviation caused by load changes, gears should adopt hard tooth surface carburizing and quenching technology (tooth surface hardness reaches HRC60~62), and bearings with stronger load-bearing capacity should be preferred as double row tapered roller bearings to enhance the overall rigidity of the system.
