Advantages and Disadvantages of Planetary Gear Reducers
Its advantages include large speed ratio and small size, while its disadvantages are higher technical requirements for maintenance, lower load capacity compared to gears, and higher price.
The advantages of cylindrical gear reducers are low failure rate, stable operation, large load capacity, simple structure, convenient maintenance, and lower price.
The disadvantages are large volume, large footprint, and susceptibility to tooth surface adhesion.
Advantages and Disadvantages of Hardened Surface Cylindrical Gear Reducers
1. The gears are made of high-strength low-carbon alloy steel through carburizing and quenching, with a tooth surface hardness of HRC58-62. All gears adopt CNC grinding process, featuring high precision and good contact.
2. High transmission efficiency, smooth operation, and low noise.
3. Small volume, light weight, long service life, and high load capacity.
4. Easy to disassemble, inspect, and install.
Features of Planetary Gear Reducers
Planetary reducers are widely used in servo, stepper, DC, and other transmission systems due to their many advantages, such as compact size, high transmission efficiency, wide reduction range, and high precision. Their primary function is to reduce speed, increase torque, and lower the load/motor rotational inertia ratio while ensuring precise transmission.
Due to their structural design, the minimum single-stage reduction ratio of planetary reducers is 3, and the maximum generally does not exceed 10. Common reduction ratios include 3/4/5/6/8/10. The number of reduction stages typically does not exceed 3, but some custom reducers with large reduction ratios may have 4 reduction stages.
Compared to other reducers, planetary reducers feature high rigidity, high precision (single-stage can achieve within 1 arc minute), high transmission efficiency (97%-98% for single-stage), high torque-to-volume ratio, and maintenance-free operation throughout their service life. Because of these characteristics, planetary reducers are mostly installed on stepper motors and servo motors to reduce speed, increase torque, and match inertia.
Noise Analysis of Planetary Reducers
Increased gear noise in planetary reducer equipment is a common mechanical fault encountered during maintenance. To reduce gear noise in planetary reducers, it is necessary to first accurately determine the cause of the increased gear noise before taking targeted measures for adjustment and repair. Once the cause of the increased noise is identified, defective gears or related parts can be replaced or repaired, and areas with assembly problems can be readjusted to restore the equipment to its original noise level.
Main factors affecting increased gear noise in planetary reducers:
1. Influence of external vibration sources.
2. Increased rotational eccentricity in the gear rotation system.
3. Severe tooth surface failure.
Common methods for identifying gear noise sources in planetary reducers:
1. Analysis using transmission diagrams.
2. Analysis and judgment through intuitive observation.
3. Judgment using the red lead powder method.
4. Judgment using the dial gauge measurement method.
