Properly selected bellows couplings result in the best control over the load in any servo application. Here are tips to ensure you choose the right size for the application. Bellows couplings help maintain tight controls over loads. For years, bellows couplings have been a mainstay for efficient motion systems because they offer high torsional stiffness, […]
Servo Torque Limiters
Protection of an electromechanical system from torque overload is often assumed to be guaranteed by the current limits set in the drive parameters. But in the case of hard stops, impacts and other situations where overload occurs very rapidly, sufficient energy to do damage often exists in the rotating inertia driving the load. R+W servo-rated […]
Oilfield Encoders Eliminate Barriers
Gurnee, IL – Dynapar announces the introduction of the EN series of oilfield encoder suitable for use in Zone 1 hazardous locations. What makes the new incremental encoders unique is their ability to operate in hazardous areas without the need for intrinsic safety (I.S.) barriers. Removal of the I.S. barrier reduces system cost, simplifies wiring, […]
Safety Coupling Catalog
Zero-Max has published a 12-page Zero-Max catalog of Torq Tender overload safety couplings. These overload safety couplings disengage motor drives for overload protection. They protect motor and drive systems from jam ups and excessive loading. System designers will find this new catalog helpful when examining overload protection options for a particular system design. Available in […]
Centa’s Quality Assurance Excels
CENTA is the first company worldwide to which Germanischer Lloyd (GL) has conferred the responsibility for alternative product certification of type-approved couplings. In the future, CENTA will have the authority to carry out acceptance testing and final stamping of those couplings that have previously been classified as approved types. These tests must be performed in […]
Slip Systems for Wind Turbine Generator Protection
CENTA produces an enhanced version of its Torque Hub, the slip clutch which offers a simple and low-cost design for torque overload generator protection. In wind power plants, electrical circuit problems are known to cause short-term torque peaks. In this event, slip clutches protect the costly gearbox against overload by slipping at a defined maximum […]
Tips to simplify coupling selection
For a coupling in a servo application to work properly, you need to satisfy a number of application factors including: torque, shaft misalignment, stiffness, speed, and space requirements. Here’s a look at the available types of servo couplings and what you need to consider for each of them during the selection process. Beam couplings Beam […]
Test bed coupling Centax-Test
Growing requirements for performance, emissions, consumption and service life of modern engines are the great challenges facing engine manufacturers today. Investment in research and development has grown considerably. With highly flexible CENTAX-TEST, CENTA provides a suitable test bed coupling for such tasks. Due to its torsionally soft characteristics, vibrations in the drive train are reduced, […]
High Torque Servo Couplings
Heavy duty torque ratings and high strength conical clamping hubs make BK3 couplings the choice for high torque servo gearboxes. Manufactured with a double-walled stainless steel bellows to absorb parallel, angular and axial shaft misalignment, the BK3 has an extremely high torsional stiffness to complement its relatively very low moment of inertia – allowing it […]
Stafford Rigid Coupling Adapters
Wilmington, MA – Stafford Manufacturing Corp. introduces a new standard line of rigid shaft coupling adapters that mate dissimilar style shafts to simplify retrofit, maintenance, and repair applications. Stafford Rigid Coupling Adapters provide an effective way to upgrade and retrofit machinery and conveyor drive components by permitting the user to change the configuration and size […]
