What advantages do SERVO Flex flexible couplings offer?
Extremely light and torsionally rigid flexible coupling
This coupling model is a metal disc coupling made from a light, high-strength aluminium alloy. Two fastening systems are available for mounting: a bore with keyway and a friction-locked clamping connection. The coupling offers high torsional stiffness and responsiveness. Type 1 with a single element and high rigidity and Type 2 with a double element
with very high flexibility are available. Every coupling type is RoHS compliant.
Features
- Hubs made from high-strength aluminium alloy
- Very low moment of inertia
- No use of hazardous substances, RoHS compliant
- Extremely torsionally rigid “single-element” coupling
- Highly flexible “double-element” coupling
- Compatible with tapered shafts
- Clamping element adjusted with just one screw
Detailed product information with further details of the new coupling series is available on request – there you will find a full description of the types as well as the geometric dimensions and performance data of the various frame sizes. Please send us your
enquiry if required!
Why are slip hubs important for protecting drives?
Our slip hubs protect machines whose drives consist of sprockets, gears or belt pulleys against overload damage. The slip hubs are robust, easy to adjust and simple to fit. They transmit torque in both directions of rotation. The organic friction linings are wear-resistant, run dry and produce a friction-locked connection between the input and output elements.
The required torque is set with an adjusting nut by tensioning disc springs. These disc springs can be arranged in single or multiple layers (see disc spring arrangement). This results in a comparatively precise torque setting between 7% and 100% of the maximum torque. The slip hubs must be protected from oil and grease. The set torque, the condition of the friction linings and correct functioning are to be checked from time to time.
The drive elements to be fitted must be plane-parallel (0.02 mm) at the friction surfaces, with a maximum roughness depth of 6 µm. The width of the sliding ring is to be matched to the transmission elements.
How are chain couplings constructed?
Standard chain couplings consist of 2 standard sprockets with a hub on one side, which are coupled to each other by a duplex roller chain to DIN 8187. They ensure flexible transmission of the torque. Thanks to its simple design, the connection can be released quickly. Small deviations in shaft alignment are compensated for. Even so, we recommend keeping these deviations as small as possible.
When selecting the chain coupling, multiply the power to be transmitted by the shock factor (between 1.0 and 4.0) and select the coupling size according to the resulting product.
What properties do our gear couplings have?
Our gear couplings are torsionally rigid shaft connections that compensate for axial (+ 1 mm), radial (+ 0.4 mm) and angular (2°) shaft misalignment. Thanks to the crowned tooth form and the plastic/steel material pairing, the couplings operate maintenance-free even in continuous duty and are virtually wear-free. The nominal torques [Mt] may be exceeded by 100 % for short periods.
The standard shaft compensating couplings are supplied with a spider of 92 Shore A. For higher torques, a spider with 95 to 98 Shore A can be used – please send us your enquiry!
