Reducer has a wide range of applications in many economic and industrial fields, mainly used to reduce speed and increase torque, playing an irreplaceable role. However, there are many types and models of reducers, and the performance of different parameters varies greatly. When evaluating the performance of reducers, the following parameters play a decisive role.
1. Rated Output Torque
Parameter Meaning: The maximum torque (Nm) that can be continuously and safely output under specified service life and working conditions.
Reflecting Performance: A core bearing capacity indicator, which is a comprehensive reflection of design strength, material strength, heat treatment, gear contact strength, and bearing selection.
Comparison Significance: The larger the value, the stronger the load capacity. It is necessary to pay attention to its test standards (such as S1/S5 duty systems). The maximum output torque of EED helical gear reducer can reach 18,000 Nm.
2. Peak/Maximum Instantaneous Torque
Parameter Meaning: The maximum torque that can be withstood in a short time without permanent damage (usually a multiple of the rated torque).
Reflecting Performance: Impact overload resistance and safety factor design.
Comparison Significance: The higher the multiple, the stronger the ability to cope with sudden loads, and the higher the system safety.
3. Efficiency
Parameter Meaning: The ratio (%) of output power to input power.
Reflecting Performance: An indicator of internal energy loss (friction loss, oil churning loss, wind resistance loss), which is closely related to gear design, machining accuracy, bearing friction, and lubrication.
Comparison Significance: The higher the efficiency, the higher the energy utilization rate, the less heat generation, and the more economical operation. High efficiency usually means better design and technology. It is necessary to pay attention to the efficiency curve under different loads/speeds. The transmission ratio of EED worm gear reducer is 5-100, and the transmission efficiency reaches 90-95%.
4. Power Density
Parameter Meaning: The power that can be transmitted per unit volume or unit weight (kW/kg or kW/m³).
Reflecting Performance: A comprehensive reflection of structural design optimization, material application level, and manufacturing process (allowing more compact design).
Comparison Significance: The larger the value, the smaller the volume and lighter the weight of the reducer under the same power/torque requirements, which is conducive to the miniaturization and lightweight of equipment. EED precision planetary reducers adopt modular design, with small volume, saving installation space and low maintenance cost.
5. Starting Torque/Operating Torque
Parameter Meaning: The torque required at the moment of starting and the torque required for stable operation.
Reflecting Performance: The size of internal static friction torque, which is related to lubrication status, sealing design, and assembly preload.
Comparison Significance: The lower the starting torque, the faster the system response, which is especially important for servo systems.
Core parameters are the foundation, and a brand's successful application cases and user reputation in specific fields are also important references. Founded in 1984, EED transmission has accumulated more than 40 years of reducer manufacturing experience, created its own brand EED, and its manufacturing process and product performance are in a leading position in the market.
