High Speed Diaphragm Coupling Manufacturer - Shreeji Gears

High-Performance Diaphragm Couplings

Shreeji Gears is a specialist diaphragm coupling manufacturer, engineering high-performance couplings for critical, high-speed, and high-torque applications. Diaphragm couplings use flexible metallic diaphragms to transmit torque while accommodating misalignment.

Renowned for their zero backlash, high torsional stiffness, and exceptional high-speed capability, these couplings are maintenance-free. They are the preferred choice for turbines, compressors, and equipment requiring compliance with standards like API 671.

Understanding Diaphragm Couplings

Diaphragm couplings transmit torque through thin, flexible metal diaphragms bolted to the driving and driven hubs. The flexing of these diaphragms accommodates angular, axial, and parallel misalignment. Their all-metal construction allows for superior performance characteristics.

Key Advantages:

  • Zero Backlash: The solid metallic torque path ensures no backlash, critical for precise control systems.
  • High Speed & Low Vibration: Inherently balanced design allows operation at very high speeds with minimal vibration, essential for **turbomachinery**.
  • High Torsional Stiffness: Provides excellent resistance to torsional deflection for accurate torque transfer.
  • Maintenance-Free: All-metal construction eliminates the need for lubrication and routine maintenance.
  • API 671 Compliance: Can be designed and manufactured to meet the stringent requirements of API 671 for special-purpose couplings.

Common Configurations:

  • Single Diaphragm Pack: Accommodates angular and axial misalignment.
  • Double Diaphragm Pack (with Spacer): Accommodates angular, axial, AND significant parallel misalignment.
