Application Analysis of Couplings in Test Benches

Ball-Type Constant Velocity Universal Couplings

1. Connection types: shrink disc, locking ring, flange, sleeve, direct connection

2. Structural types: single joint, double joint, telescopic

3. Mechanical properties: no need for high-precision alignment, large angular capability, high rotational speed

4. Applicable applications: most test conditions up to 12,000 rpm

High-Elastomer Ball-Type Constant Velocity Universal Couplings

1. Connection type: flange

2. Structural types: high-elastomer element ball-type (single or double joint), high-elastomer element driveshaft

4. Mechanical properties: compensation, vibration reduction

5. Applicable applications: diesel engines, gasoline engines, hydraulic pumps, air compressors, etc .

6. Maximum rotational speed: 8,000 rpm

High-Speed Disk-Type Couplings

1. Connection types: shrink disc, locking ring, clamping, keyway, flange, sleeve

2. Structural types: single diaphragm, double diaphragm, carbon fiber tube

3. Mechanical properties: high speed, low inertia, high stiffness, high dynamic response, vibration damping

4.. Maximum rotational speed: 30,000 rpm

Diaphragm-Type Coupling s

1. Connection types: shrink disc, locking ring

2. Structural types: double diaphragm, with intermediate tube

3. Mechanical properties: high speed, high dynamic response, low inertia, vibration damping

4. Applicable applications: ultra-high-speed testing (aero-engines, air separation plants, fans, etc.)

5. Maximum rotational speed: 60,000 rpm
