Torsionally flexible jaw couplings with SPLIT hubs

ROTEX S-H with split hubs

Radial disassembly possible even in narrow spaces: ROTEX® S-H with SPLIT hubs

In 1967 the torsionally flexible ROTEX® jaw coupling made its debut. Ever since, we have continued to refine our traditional model, as we did this year. The reasoning that led us to our most recent novelty was as simple as it was ingenious: when a cast connection rod is split, this enables a precise positive fit. By transferring this production procedure to the ROTEX hubs SPLIT hubs are generated forming the ROTEX® S-H when being combined: Cracking produces cracked surfaces that are used for centring the hub halves. That is why costly machining of the surfaces can be done without which finally results in cost saving. This system furthermore provides the benefit that the coupling can easily be assembled and disassembled despite narrow mounting space. A minimal dismounting dimension.is the only thing that has to be considered.  

Basically the hubs are cracked with minimum pilot bore. Afterwards there is the possibility to produce the requested finish bore by means of a standard CNC machine.

These are the advantages the ROTEX® S-H offers:

  • Radial assembly / disassembly possible
  • Easy mounting and dismantling by means of four screws
  • Centring of both hub halves through the split plane
  • Simplified bore finishing (pilot bored and already cracked from stock)
  • Block assembly (when tightening the cap screws you do not need to make sure of the same slot width such as with the ROTEX® A-H)
  • ATEX-compliant (according to EU-guideline 2014/34/EU)
  • Maintenance free
  • Statically balanced (dyn. balancing recommended from 25 m/s)
  • ROTEX® S-H hub material:

    • Sinter material (ROTEX® S-H sizes 24 – 28 up to TKN = 160 Nm) from stock
    • Grey cast iron material (ROTEX® S-H sizes 38 – 90 up to TKN = 3,600 Nm) from stock
    • Spheroidal graphite iron (ROTEX® S-H sizes 100 – 180 up to TKN = 35,000 Nm)

Application range:

  • General mechanical engineering
  • Pumps and compressors 
  • Materials handling
  • Fans
  • Mixers
  • etc.

Radial assembly and disassembly without displacing the power units

​​​​​The shells are radially put onto the shaft, both from the top and from the botton. The power units do not need to be removed or moved from the machine bed.

Particularly for:

  • very tight installation space → radial assembly
  • high-maintenance machines → easy and fast coupling assembly
