What is a Gearbox？
A gearbox is an enclosed power transmission device that changes speed and torque, consisting of gears, bearings, shafts, and housing.
Core Functions
| Function | Description |
|---|---|
| Speed Change | Change input speed |
| Torque Change | Reduce speed to increase torque |
| Direction Change | Perpendicular, parallel, or angled transmission |
| Power Distribution | One input drives multiple outputs |
Main Types
| Type | Characteristics | Applications |
|---|---|---|
| Helical | Smooth, quiet, 98% efficiency | Conveyors, mixers |
| Planetary | Compact, high power density | Wind turbines, machine tools |
| Worm | High ratio, self-locking, quiet but low efficiency | Elevators, packaging |
| Bevel | Right-angle transmission, durable | Auto differentials, print presses |
| Spur | Simple, low cost, noisy | Low-speed packaging |
Selection Key Parameters
- Torque：Maximum load required
- Ratio：Input/output speed ratio
- Efficiency：Affects energy consumption and heat
- Mounting：Horizontal/vertical/flange
- Environment：Temperature, dust, corrosion
