Gearbox Performance Overview

Specifications:
The document provides detailed specifications for various gearbox models (PS40, PS70, PS90, etc.) across different stages and 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, protection degree, mounting position, and noise level.

Nominal Output Torque:
Torque values are provided for different stages and ratios, ranging from 3 Nm to 17,000 Nm depending on the model and configuration.

Input Speed:
Nominal input speeds range from 1,500 rpm to 4,500 rpm, while maximum input speeds range from 2,500 rpm to 10,000 rpm.

Backlash:
Micro, reduced, and standard backlash values are specified, with micro backlash ranging from 3 to 5 arcmin, reduced backlash from 5 to 14 arcmin, and standard backlash from 7 to 18 arcmin.

Load Capacities:
Maximum radial load capacities range from 160 N to 55,000 N, and axial load capacities range from 160 N to 65,000 N.

Service Life and Efficiency:
The service life is specified as 25,000 to 15,000 hours, with efficiency levels of ≥96% for stages 1-10 and ≥94% for stages 9-100.

Dimensions:
Detailed dimensions for each model are provided, including output and input dimensions, mounting positions, and other critical measurements.

Inertial Properties:
Mass moments of inertia are listed for each model and stage, providing insights into the dynamic performance of the gearboxes.

Additional Features:
The gearboxes are designed for all-direction mounting, operate within a temperature range of -10°C to 90°C, use synthetic lubrication grease, and have a protection degree of IP64. Noise levels range from 56 dB(A) to 85 dB(A) depending on the model and configuration.
