Gearbox

Gearboxes, also known as speed reducers or gear reducers, are mechanical transmission devices that reduce motor speed while increasing torque. They consist of a housing, gears (helical, worm, or planetary), shafts, and bearings. Key technical parameters include reduction ratio (e.g., 5:1 to 100:1), input speed (typically up to 3000 RPM), output ...

Gearboxes, also known as speed reducers or gear reducers, are mechanical transmission devices that reduce motor speed while increasing torque. They consist of a housing, gears (helical, worm, or planetary), shafts, and bearings. Key technical parameters include reduction ratio (e.g., 5:1 to 100:1), input speed (typically up to 3000 RPM), output torque (measured in Nm), efficiency (up to 95% for helical types), and mounting configurations (foot-mounted, flange-mounted, or shaft-mounted). Gearboxes are available in various frame sizes and materials, such as cast iron or aluminum, with IP protection ratings from IP54 to IP65 for harsh environments.

Gearboxes are essential in industrial automation, conveyor systems, material handling, packaging machinery, and robotics. They are installed in motor-driven applications where precise speed control and high torque are required, such as in assembly lines, cranes, mixers, and pumps. They also find use in renewable energy systems like wind turbines and solar trackers, as well as in automotive and agricultural equipment.

Our category includes helical gearboxes (e.g., series H, with ratios from 1.25:1 to 450:1), worm gearboxes (e.g., series W, with ratios up to 100:1 and self-locking capability), and planetary gearboxes (e.g., series P, with high torque density and ratios up to 1000:1). Key article codes follow patterns like GB-H-100-5 (helical, size 100, ratio 5:1) or GB-W-63-20 (worm, size 63, ratio 20:1). We also stock right-angle gearboxes and servo gearboxes for precision applications.
