FF Parallel-Shaft Helical Geared Motor

MANUFACTURER DOCUMENTATION

Overview

Xinghai’s FF series is a parallel-shaft helical geared motor designed for installations where an inline drive would occupy too much length. The official page lists foot, flange and shaft-mounted arrangements, a headline output-speed envelope of 0.1 to 752 rpm, and up to 12,000 Nm output torque. It also gives a motor-power envelope of 0.12 to 90 kW. A frame table spans multiple sizes and mounting structures; its row values must be checked individually because the fastest speed, highest torque and largest motor do not describe a single gearbox. Gear material and processing are described as alloy steel with carburizing, hardening and tooth grinding. Confirm the selected FF frame, input motor and service factor with Xinghai.

Before you specify this gearbox

Helical gearboxes are used in a broad range of industrial drives. Mounting position, service factor, thermal capacity and lubrication are part of selection, not just the nameplate power.

• Confirm continuous, peak and emergency-stop load limits separately.
• Match the motor flange, shaft, mounting orientation and lubrication requirements.
• Request the current drawing revision and selection calculation from the manufacturer.
