Safety couplings Mayr EAS-Compact with extensive torque limitation capabilities on the part of the drive unit in order to avoid equipment breakdowns in case of system overload. Precise transmission of power characteristics to the driven shaft, high joint stiffness with respect to torsion, low moment of inertia. Easy to install, high wear resistance and minimal maintenance requirements.
A wide range of standard sizes and design solutions for optimal selection, three types of functional design: ratchet and synchronous couplings with automatic engagement after eliminating the causes of exceeding the permissible load values, disconnecting couplings with forced reconnection.
Types of ratchet and synchronous safety couplings:
- short sleeve with a conical sleeve (490._1_.0) or with a keyway (490._2_.0)
- with two bearings, with a cone sleeve (490._1_.2) or with a keyway (490._2_.2)
- protruding sleeve design, conical (490._1_.1) or with a key groove (490._2_.1)
- with metal bellows (493._ _ _ .0)
- construction with reinforced torsion resistance (496._ _ _ .0)
- with an elastic joint of different Shore hardness (494._ _ _ .3 - 92A, 494._ _ _ .4 - 98A, 494._ _ _ .6 - 64D)
Types of disconnecting safety couplings:
- short sleeve with a conical sleeve (490._14.0) or with a keyway (490._24.0)
- with two bearings, with a cone sleeve (490._14.2) or with a keyway (490._24.2)
- protruding sleeve design, conical (490._14.1) or with a key groove (490._24.1)
- construction with reinforced torsion resistance (496._ _ 4 ._)
- with an elastic joint of different Shore hardness (494._ _ 4 .3 - 92A, 494._ _ 4 .4 - 98A, 494._ _ 4 .6 - 64D)
