Ameriflex Diaphragm Couplings

Since its introduction in 1971, the Ameriflex multi-layered diaphragm couplings have continued to set new standards for lifespan and reliability for high-performance machinery. Today, utilizing the latest design and manufacturing technologies, Ameridrives Couplings can increase the performance of diaphragm couplings without compromising this exceptional reliability.

Advanced analysis and manufacturing processes have provided an increase in capacity without reducing safety factors. The validation of the latest finite element analysis methods with strain gauge and dynamic tests has allowed for a more precise calculation of Ameriflex diaphragm stresses.

Key Features:

• Designed for infinite life
• High torque-to-diameter and weight ratio
• Diaphragms are manufactured from 15-5PH stainless steel
• Diaphragms shot-peened to increase fatigue strength and corrosion resistance
• Low bending moments and axial forces lead to lower bearing loads
• High axial displacement
• Multiple separate diaphragms provide an inherent safety feature
• Failure develops gradually, and offset stress is reduced in the remaining diaphragms
• Design flexibility by changing the number of diaphragms
• Field-replaceable flex-element assemblies
• API-671 compliant"
