Core parameters and applicable scenarios of NBZD250-71-1 planetary gear reducer

The core parameters and applicable scenarios of NBZD250-71-1 planetary gear reducer are as follows:

1、 Key technical parameters:

Machine base number (250): Corresponding to a center distance of about 250mm for the equipment, the size and load-bearing capacity of the casing are fixed, and it is usually matched with a motor power range of 15-45KW (please refer to the manufacturer's sample for details, there may be slight differences among different manufacturers).

Transmission ratio (71): It belongs to a large transmission ratio design. After the input speed (such as a motor 1500r/min) is reduced, the output speed is about 21r/min (1500 ÷ 71 ≈ 21), which is suitable for low-speed and high torque load requirements (such as conveyor belt drives and mixing equipment).

Power and efficiency: The transmission efficiency of the two-stage planetary reducer (NBD/NBZD) can reach 96%, suitable for medium to high power scenarios.

2、 Typical applicable scenarios:

Industrial equipment:

In heavy-duty fields such as lifting and transportation, engineering machinery, metallurgy and mining, high torque and reliable transmission are required.

Mechanical equipment such as plastic rubber extruders and mixing plants that require stable deceleration.

Precision transmission:

CNC machine tools, robot joints, and other applications that require high transmission accuracy need to be used in conjunction with servo systems.

Special environment:

When working in high temperatures or outdoors, it is necessary to ensure that the lubrication system (such as circulating oil cooling) and sealing performance are good.
