Divided pulleys

Easier installation and dismantling

In many cases the whole drive with all components needs to be elaborately dismantled and afterwards reinstalled when exchanging or replacing drive pulleys. To simplify this process we offer divided pulleys which can be disassembled in two halves and perfectly put together again at the shaft.

We produce all sorts of divided pulleys (v-belt pulleys, flat belt pulleys, band wheels etc.) as exclusive custom-made products. Depending on the requirement the pulley will be implemented as arm or base pulley.

All geometries can be easily produced in a flexible, model-free moulding process. Divided pulleys are produced from batch sizes larger than 1 piece for urgently needed spare parts , prototypes, zero-series models or series according to individual requests or drawings.

In close cooperation with the customer we develop the optimal solution for individual drives.

For the production of divided pulleys we already separate the raw casting – using the predetermined breaking points – just to reassemble and fix it immediately afterwards. The gray cast structure, which almost didn´t deform elastically before the fracture, is used to achieve a perfect fit at the breakpoint for seamless reassembling.

The experience over many years of casting with predetermined breaking points, blasting and subsequent mechanical treatment of the divided pulleys makes a customized highbrow drive unit.

At a glance

  • Standard material: cast iron EN-GJL-200 to EN-GJL-300 (GG-20 to GG-30) according to DIN EN 1561
  • Execution for circumferential speeds up to 30 m/s in gray cast EN-GJL-200 to EN-GJL-300
  • Produced according to DIN 2211 / 2217 or individually varying
  • All common flat and v-belt profiles: SPZ, SPA, SPB, SPC, 20, 25, 32, 40, 3V, 5V, 8V, Poly-V etc., plus all v-belt special profiles
  • Shaft-hub connections with cylindrical drill, tolerance field for press fittings, with or without feather key, preparations for the intake of couplings, flanges etc.
  • Arm or base pulley designs
  • By default divided pulleys are balanced in grade G16, G6.3 or G2.5
  • All surfaces are grounded to avoid corrosion, processed functional surfaces are conserved with spray wax / oil
  • Individual surfaces and special varnishes as well as corrosion protection are possible according to individual specifications
  • Upon request we offer detailed documentation to prove material properties, balancing qualities and surface treatments
 

The benefits

  • Custom-made products according to individual customer specifications or drawings
  • Support with drive set up, control, recalculation and optimization
  • Pulley geometries are optimally adjusted to the corresponding drive situation
  • If required full transparency due to approval drawings prior to production start or for detailed documentation
  • Flexible moulding procedure without individual models and model cost
  • Short-term availability of urgently needed spare parts in case of machine breakdown
