PRODUCT SPECIFICATIONS

Ruland JD21/33-92Y es una estrella para acoplamiento de mordaza sin juego, diseñado para enbonar en los cubos Ruland con un diámetro externo de 1.313 pulg / 33.3mm. Es un componente con diseño de tres piezas, que consta de dos cubos de aluminio y un inserto elastomérico llamado estrella que crea un acoplamiento liviano de baja inercia capaz de soportar velocidades hasta 8,000 RPM. Este acoplamiento con diseño de tres piezas es altamente personalizado ya que se adapta fácilmente a cubos de abrazadera o de tornillos de fijación con agujeros en pulgadas, métricos, con o sin chavetero. PART NUMBER está hecho de poliuretano y tiene una dureza SHORE brindando un buen equilibrio de amortiguación y capacidad de torsión. Los acoplamientos de mordaza Ruland tienen un diseño balanceado para reducir la vibración a altas velocidades. Los tornillos son métricos y su prueba de fuerza supera los estándares DIN 912 129 para una capacidad máxima del par. JD21/33-92Y se fabrica conforme a los reglamentos RoHS3 y REACH.

Product Notes

Nota 1

Performance ratings are for guidance only. The user must determine suitability for a particular application.

Nota 2

Torque ratings for the couplings are based on the physical limitations/failure point of the spiders. Under normal/typical conditions the hubs are capable of holding up to the nominal torque of the spiders. In some cases, especially when the smallest standard bores are used or where shafts are undersized, slippage on the shaft is possible below the nominal torque of the spiders. Keyways are available to provide additional torque capacity in the shaft/hub connection when required. Please consult technical support for more assistance.

Prop. 65

This product does not require a warning.

Installation Instructions

  1. Align the bores of the jaw coupling hubs on the shafts that are to be joined and determine if the misalignment parameters are within the limits of the coupling.(Angular Misialignment: 0.9 deg, Parallel Misalignment: 0.005 in (0.13 mm), Axial Motion: 0.03 in (0.76 mm))
  2. Fully tighten the screw(s) on the first hub to the recommended seating torque using a hex torque wrench.
  3. Insert a spider into the jaws of the first hub until the raised points contact the base of the hub.
  4. Insert the jaws of the second hub into the spider openings until the raised points contact the base of the second hub. Some force will be required to insert the second hub. This is normal.
  5. Assure that a gap is maintained between the two hubs so there is no metal to metal contact. Fully tighten the screw(s) on the second hub to the recommended seating torque.
