Gearbox Performance Overview

Specifications:
The document provides detailed specifications for various gearbox models (AF70, AF90, AF115, AF142, AF180, AF210, AF240) and their performance metrics across different stage ratios. Key parameters include nominal output torque, maximum output torque, emergency stop torque, nominal and maximum input speeds, backlash levels, torsional rigidity, radial and axial load capacities, service life, efficiency, weight, operating temperature, lubrication type, degree of protection, mounting position, and noise level.

Nominal Output Torque:
Varies by model and stage ratio, ranging from 27 Nm to 3500 Nm.

Maximum Output Torque:
1.6 times the nominal torque.

Emergency Stop Torque:
3 times the nominal torque.

Input Speed:
Nominal input speed ranges from 2000 rpm to 4000 rpm, while maximum input speed ranges from 4000 rpm to 6000 rpm.

Backlash:
Micro, reduced, and standard backlash values are provided, with micro backlash ranging from 2 to 4 arcmin.

Load Capacities:
Maximum radial load ranges from 3200 N to 30000 N, and maximum axial load ranges from 4400 N to 31000 N.

Service Life and Efficiency:
Service life is 25000 hours, with efficiency ≥96% for stage 1 and ≥94% for stage 2.

Environmental and Operational Conditions:
Operating temperature is between -10°C and 90°C, with synthetic lubrication grease used. The degree of protection is IP64, and the gearbox can be mounted in all directions.

Noise Level:
Ranges from 60 dB(A) to 75 dB(A) depending on the model.

Gearbox Inertial Data:
Mass moments of inertia are provided for different models and stage ratios, indicating the rotational inertia of the gearboxes.

Dimensions:
Detailed dimensions for each model are provided, including output and input dimensions, which are crucial for installation and compatibility with other mechanical components.
