FAQ
Q: When to replace a reducer?
A: Signs include torque loss, metallic debris in oil, or overheating. Proactive replacement avoids catastrophic failure.
Q: How to choose the right reducer?
A: Key factors include torque requirements, speed ratio, mounting space, precision (e.g., backlash), operating environment (dust/water/corrosion resistance), and budget.
Q: How to extend service life?
A: Use synthetic lubricants, monitor load cycles, and install vibration sensors for early fault detection.
Q: Common failure modes?
A: Planetary gear pitting, bearing spalling, and shaft misalignment are typical. Regular oil analysis helps detect wear.
Q: What is the basic working principle of a reducer?
A: Reducers convert high-speed, low-torque input into low-speed, high-touque output through gear meshing or friction transmission, achieving power transmission and speed regulation.
