What is the maximum speed ratio of the planetary reducer?

Planetary reducer is a widely used industrial transmission product, which needs to be used in many industries. It can reduce the motor speed and increase the output torque. What is the maximum gear ratio of the planetary reducer?

1. The gear ring is fixed, the sun gear is active, and the planet carrier is passive; This combination is a reduction drive, usually with a transmission ratio of 2.5 - 5 and the same steering direction.

2. The gear ring is fixed, the planet carrier is active, and the sun gear is passive; This combination is an accelerated transmission with a transmission ratio of 0.2 - 0.4 and the same steering direction.

3. The sun gear is fixed, the ring gear is active, and the planet carrier is passive; This combination is a reduction drive, with a transmission ratio of 1.25 - 1.67 and the same steering.

4. The sun gear is fixed, the planet carrier is active, and the gear ring is passive; This combination is accelerated transmission, with a transmission ratio of 0.6-0.8 and the same steering.

5. The planet carrier is fixed, the sun gear is active, and the gear ring is passive; This combination is a reduction drive, with a transmission ratio of 1.5 to 4, and the steering direction is opposite.

6. The planet carrier is fixed, the gear ring is driven, and the sun gear is passive; This combination is an accelerated transmission with a transmission ratio of 0.25 - 0.67, and the steering is opposite.

Different operation modes of planetary reducer form different reduction ratios. When purchasing planetary gear reducer, the reduction ratio and transmission ratio should be considered.
