Limiting high torques reliably

In addition to numerous other innovations, mayr® power transmission is to present a large disengaging torque limiting clutch for torques of up to 280,000 Nm at the Hannover Trade Fair. This large clutch for heavy engineering is combined with curved tooth couplings for the connection of two shafts.

Disengaging EAS®-element clutches for heavy engineering disengage the input and output on overload. The energy from the rotating masses stored in the system can slow down freely.

As international market leaders, mayr® power transmission has provided the widest product range of load holding, load disconnecting, torque and force limiting, frictionally locking, positive locking, magnetic, regulatable and switchable torque limiting clutches for decades.

In spite of this wide range, the company have noticed an increasing demand for new torque limiting clutches with extremely high torques and for application-optimised solutions. For this reason, the performance range of the disengaging EAS®-element clutches has been extended at the time of the Hannover Trade Fair in 2011. The latest design with curved tooth couplings for the connection of two shafts is designed for torques of up to 280,000 Nm.

EAS®-element clutches transfer the torque using positive locking during normal operation. On overload, they separate the input and output nearly residual torque-free with a high switch-off and repeat accuracy. The kinetic energy from the rotating masses stored in the system can slow down freely. Such disengaging clutches do not automatically re-engage. They remain disengaged until they are re-engaged either manually or via mechanical or hydraulic devices.

For 30 years, disengaging EAS®-element clutches have been protecting systems and drives in heavy engineering against expensive overload damage. Our decades of experience and the collective, comprehensive know-how make mayr® power transmission your ideal partner for mechanical overload protection in drives with extremely high torques, high speeds and large mass moments of inertia.

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
