Speed reducers can be classified into gear reducers, worm reducers, and planetary reducers according to transmission types, and into general-purpose reducers and special-purpose reducers according to applications. The effectiveness of a speed reducer is not only determined by its parameter specifications but also influenced by its manufacturing process. In actual production, which factors affect the performance of speed reducers? The following are the main references:
1. Transmission Accuracy
Parameter Meaning: The deviation (arcseconds/arcminutes) between the actual position and theoretical position of the output shaft.
Reflected Processes: Gear machining accuracy (tooth profile, tooth direction, circular pitch), assembly accuracy (bearing preload, gear meshing clearance), and housing machining accuracy (hole position, concentricity, perpendicularity). High-precision speed reducers require extremely low transmission errors.
Comparison Significance: The smaller the value, the more precise the process, suitable for high-precision positioning scenarios (e.g., robots, machine tools). The gear accuracy grade of EED helical gear reducers reaches DIN6, and each product undergoes strict quality control and 100% operation testing.
2. Backlash
Parameter Meaning: The maximum angle (arcminutes) by which the output shaft can slightly rotate when the input shaft is fixed.
Reflected Processes: Control of gear meshing clearance, bearing clearance, and tolerance of component fits. Exquisite processes can achieve minimal or even zero backlash.
Comparison Significance: The smaller the value, the better the transmission rigidity, faster response, and no empty stroke—critical for applications with frequent start-stop and direction changes (e.g., robot joints). Excessive backlash leads to inaccurate positioning, vibration, and noise. EED precision planetary reducers feature advantages such as low noise, low backlash, and compact size.
3. Torsional Stiffness
Parameter Meaning: The elastic torsional deformation of the output shaft under unit load torque (arcmin/Nm or Nm/arcmin).
Reflected Processes: Material of gears and shafts, heat treatment hardness, structural design rigidity, and matching rigidity of bearings and splines.
Comparison Significance: The larger the value (smaller deformation), the stronger the system rigidity, better dynamic response performance, higher impact resistance, and better positioning accuracy retention.
4. Temperature Rise
Parameter Meaning: The difference between the speed reducer temperature and ambient temperature when running under rated load and speed until thermal equilibrium is reached.
Reflected Processes: Machining finish of friction pairs (gears, bearings), assembly accuracy, rationality of lubrication design, and thermal balance design. Poor processes lead to high friction and heat generation.
Comparison Significance: Lower temperature rise indicates smaller internal friction loss, higher efficiency, longer life for seals and lubricants, and superior processes.
5. Noise and Vibration
Parameter Meaning: Sound pressure level (dB) and vibration acceleration/velocity during operation under specific working conditions.
Reflected Processes: Quality of gear modification, dynamic balance precision, assembly concentricity, bearing quality, housing rigidity, and vibration reduction design. Rough processes are the main noise sources.
Comparison Significance: Lower noise and vibration mean smoother internal operation, better gear meshing and bearing performance, superior processes, and improved user experience. EED worm gear reducers are renowned for low noise, with noise ≤65 decibels.
