Acoplamentos de eixos - Para compensar a transmissão do torque

Acoplamentos de eixos: Para compensar a transmissão do torque

Acoplamentos de eixos de mayr® Antriebstechnik trabalham de forma a amortecer as vibrações, e de forma precisa: transmissão de torque sem folga do líder de mercado global.

mayr® Antriebstechnik fabricam uma grande seleção de acoplamentos de eixos de elevado valor para fazer uma ligação sem folga entre dois eixos. Os acoplamentos de mayr são caracterizados por uma capacidade de resistência e pela sua funcionalidade mesmo com flutuações de temperatura, vibrações ou outras influências externas. Os nossos acoplamentos de conjunto de lâminas e acoplamentos de elastómero transmitem o torque de forma precisa e confiável. Os acoplamentos de fole metálico compensam por desalinhamentos de eixos ou erros de alinhamento. mayr Antriebstechnik oferece não só soluções para limitadores de torque de elevada eficiência, mas também o apoia na construção e documentação de dados CAD e folhas de dados assim como na configuração do seu acoplamento de eixos desejado.

Shaft couplings from the world market leader

At mayr® power transmission you will find an extensive selection of shaft couplings for the backlash-free connection of two shafts. Our couplings can withstand severe temperature fluctuations, vibrations or other external influences and deliver precise functionality over extended time periods.

Our shaft couplings can be broadly categorised into two types : torsionally rigid or torsionally flexible.

mayr® power transmission not only offers you high-performance standard coupling solutions, but we can also support you with special to application designs and provide comprehensive documentation including drawings, CAD files, data sheets and installation instructions. Sign up to Mayr+ on our website (mayr.com) and you can configure and download your own coupling designs and directly request a quotation.

 

What are Torsionally Rigid couplings?

Our torsionally rigid metal membrane or disc couplings (ROBA-DS) (Multi-plate couplings) and our metal bellows couplings (smartflex) are designed to transmit torque with zero rotational twist between the input and output sides of the coupling.

 

Disc couplings (Multi-plate couplings)

mayr® power transmission disc couplings are available in a wide variety of standard designs and sizes and can be selected with keyway, shrink disc, clamping or split hubs in various sizes and with single or double flexible disc packs to accommodate angular, axial and radial misalignment.

Where there is a large distance between shaft ends (DBSE) spacer sleeves can be added between the disc packs and these can be produced in a variety of materials including steel, aluminium and carbon fibre (CFRP) to suit the application.

Our torsionally rigid disc couplings come in a number of different product types including    

 

Metal bellows couplings

The mayr® power transmission smartflex metal bellows coupling is based on a patented weld-free design and can compensate for axial, angular and radial shaft misalignments. They are suitable for servo and other highly dynamic drives and can operate at high shaft speeds. The smartflex® is a modular coupling design that can be easily disassembled by hand and variations in shaft size can be accommodated by simply swapping out the hub insert for one with a different bore size. Our smartflex couplings can be supplied with either long or short bellows to suit the customer’s application, and they offer reliable torque transmission with a very low mass moment of inertia (MMI).

 

What are Torsionally Flexible couplings?

Our range of flexible shaft couplings also includes elastomeric couplings often referred to as spider or jaw couplings. These transmit the torque precisely and reliably and have a rotation angle equalising and vibration damping effect. The backlash-free ROBA®-ES, pluggable and maintenance-free shaft couplings can be supplied with a wide range of hub styles and now with double elements and spacer sleeves to span distances between shafts.

ROBA®-ES features fully machined transmission surfaces providing a precision fit of the elastomer element to ensure backlash free transmission and extended life. Elastomers can be supplied in a wide range of hardnesses to suit the customer’s application and provide the required amount of misalignment compensation and vibration reduction.    

 

Application examples of our shaft couplings

Every drive has its own special characteristics and places very different demands on the couplings that transmit the torque from one shaft to another and compensate for any shaft misalignment. With disc, metal bellows and elastomer couplings, mayr® power transmission offers the right solution for many different applications and drives. The shaft couplings can be used in the following areas:

  • servo drives
  • high speed and highly dynamic drives
  • heavy-duty applications
  • alternating loads
  • HBM / HBK torque transducers
  • torque measurement and monitoring of test benches, machines and other production systems
