Definition and Core Functions
Drive chains are precision-engineered power transmission components that transfer mechanical energy between shafts via sprockets. They convert rotary motion at a constant speed ratio, making them an indispensable component in applications requiring positive engagement (no slip) and high torque density.
Key advantages over alternatives
Mechanical efficiency up to 96-98% (compared to 90-95% for belt drives)
Compact power transmission (higher power/space ratio than gear drives)
Tolerant misalignment (compared to gear drives)
No preload required (unlike belt drives)
Ability to operate in harsh conditions (dust, moisture, extreme temperatures)
| Type | Standard | Key Features | Typical Applications |
|---|---|---|---|
| Roller Chain | ANSI B29.1 | Most common, cost-effective | Industrial machinery, motorcycles |
| Silent Chain | ISO 10823 | Smooth, quiet operation | Automotive timing systems |
| Leaf Chain | ISO 4347 | High tensile strength, no rollers | Forklifts, lifting equipment |
| Engineering Chain | DIN 8187/8188 | Extra heavy-duty construction | Mining, oilfield equipment |
| Double-Pitch Chain | ANSI B29.3 | Longer pitch for reduced weight | Conveyors, material handling |
We also provide Sprockets.
