Introduction
Standard Overview and Technology Evolution
GB/T 33515-2017 is the core national standard in the field of magnetic powder clutches and is managed by the National Technical Committee for Standardization of Machine Shafts and Accessories (SAC/TC109). This standard replaces the early industry specifications and systematically defines the complete technical system of magnetic powder clutches for the first time, reflecting my country's technological accumulation in the field of electromagnetic transmission.
Analysis of core terms
| Terms | Definition | Typical value |
|---|---|---|
| Maximum excitation voltage | The highest operating voltage specified by the standard | 24V/80V(dc) |
| Allowable slip power [P] | Maximum allowable power during continuous slip operation | 15W-8300W |
| Safety factor Ks | Ratio of maximum torque to nominal torque | 1.3-2.0 |
Key performance requirements
Static characteristic curve requirements: no-load torque ≤3%Tn (low speed), ≤5%Tn (high speed); loop width coefficient ΔT≤15%Tn. Typical application scenarios:
- Servo drive system: require Ks≥1.5
- Overload protection device: require Ks≥2.0
Cooling method comparison
| Cooling type | Code | Allowable slip power | Applicable scenarios |
|---|---|---|---|
| Self-cooling | - | 15-2000W | Low-power intermittent operation |
| Air-cooling | F | ≥340-8300W | Medium and high power continuous operation |
| Liquid cooling | Y | ≥1400W | High power precision control |
Implementation suggestions
Key points for selection: Select the specification according to the nominal torque (0.1-63000N·m). Note that the specifications with "*" are recommended specifications. During installation, ensure the following:
- Ambient temperature -5℃~40℃, humidity ≤90%
- Axial displacement does not exceed the standard limit
- Liquid cooling requires sealing verification
Maintenance requirements: Check the magnetic powder status every 3000 working hours, and the coil temperature rise must not exceed the material grade limit (F grade ≤120℃).
