Couplings for Tachogenerators and Encoders
The coupling is the element that connects the motor shaft to the encoder or tachogenerator. It must transmit motion with absolute fidelity — without backlash, without loss of pulses — while compensating for the small radial, angular, and axial misalignments that are inevitable during installation. An inadequate coupling introduces measurement errors that affect the entire control chain.
Encoder couplings are typically one-piece aluminum alloyunits with a helical groove cut into the body: this geometry ensures high torsional rigidity — to avoid losing pulses — and sufficient axial and radial flexibility to compensate for misalignments. We distribute five specialized brands for every format and application.
Our selection of flexible couplings for encoders — which includes single-hole, double-hole, spring, and bellows models — ensures full compatibility with the main rotary transducers and tachogenerators on the market.
The Brands We Distribute
Lika Electronic
In addition to encoders, Lika produces a complete range of couplings for a wide variety of measurement applications, available in different formats to meet every installation requirement.
Eltra
Eltra precision flexible couplings are made of aluminum alloy with a helical cut that provides torsional rigidity and the ability to compensate for slight misalignments and small axial displacements. They are specifically designed for transmitting motion to the encoder shaft.
Elcis
Elcis helical couplings are machined from a single block of aluminum alloy with a helical groove: the absence of joints or welds eliminates any point of breakage or fatigue. There is no backlash under any working condition and zero maintenance is required throughout the useful life of the product.
DIN.AL.
Specialists in the design and manufacture of couplings for electronic and mechanical transmission for 25 years. The DIN.AL. range is able to meet the needs of the most diverse application sectors.
NBK Couplicon
From a Japanese company with a centuries-old history, a wide variety of precision couplings to meet even the most specific requirements.
