The Acoflex coupling is a flexible jaw coupling composed by four elements: two hubs, a elastomeric insert in between and the cover ring.
The hubs are manufactured in cast iron, each one with eight teeth, except the A-00 and A-0, which have four and six respectively.
The elastic split insert that fits over the hub teeth is manufactured with the best quality polyurethane compound, which can be supplied in three different qualities (standard, high temperature and high performance) providing the most suitable solution depending on the application requirements.
The steel cover ring is fixed to the insert with two setscrews assembling the coupling. The design allows a quick and easy installation and replacement without moving hubs and realigning either the driver or the driven equipment, reducing downtime.
The A series is the simplest construction of all Acoflex range couplings. However, more coupling configurations are available: with taper-lock bushings, spacer and double spacer arrangement, brake disc and brake drum configurations, and SAE flywheel assembly. Other designs are available upon request.
Features and benefits of flexible jaw couplings
- Zero maintenance: No routine maintenance or lubrication required
- Quick and easy installation and replacement: The design allows a quick and easy element installation and replacement without moving hubs and realigning either the driver or the driven equipment, reducing downtime
- Long lasting: The elastic insert has an excellent resistance to chemicals and wear, with different polyurethane qualities available, obtaining a maximum working temperature range from -40 °C to +140 °C
- Safe: The flexible element is retained by the cover ring and there is no metal to metal contact between both hubs, avoiding to create any possible spark
- High misalignment capabilities: Compensates high axial, angular and radial misalignments
- Shock load and vibration absorption: The elastomeric insert absorbs the shock loads and vibrations transferred to the driven equipment.
Application fields of flexible jaw couplings
- Suitable for applications with high misalignments
- When downtime and maintenance expenses are critical
- When shock load and vibration transmission damping is necessary
- Useful in low and medium power rates
