MOUNTING & DISMOUNTING – SPECIAL TOOLS

The cotter release mechanism of the Schmeckthal Group

MOUNTING & DISMOUNTING – SPECIAL TOOLS - WVW Wälzlager-Vertrieb Wiesbaden GmbH / Mainz-Kastel In some applications a simple removal of for example ball bearings using a conventional puller is not readily possible - especially if the protruding stub shaft is unusually long.

In such cases you normally either need large tools which are expensive and require more manpower in the application. Or improvised, home-made "tools" are used at high risk.

The Schmeckthal Group therefore conceived and constructed a cotter release mechanism for these specific applications.

The operating principle is based on a cotter exerting a transversal / axial force which generates a release pressure on the component to be dismantled. Since the compressive force is induced in radial direction only, the cotter release mechanism can do the job with a very flat and hence space-saving design.

In essence, the device consists of two counter-acting wedges which are connected and placed at the appropriate location around the shaft. The generation of the required force is achieved with that robust wedge construction through moving the shallower wedge by means of a screw thread in a radial direction. The resulting axial force pushes the designated component part from its seating location.

The application of the cotter release mechanism offers the following advantages:

  • Reduced expenditure of time
  • Reduced manpower requirements
  • Low weight
  • Practicality given regardless of shaft dimensions
  • Reduction of accident hazards
  • Diminishment of maintenance time
  • Improved productivity
  • Reduction of overall operating costs

MOUNTING & DISMOUNTING – SPECIAL TOOLS - WVW Wälzlager-Vertrieb Wiesbaden GmbH / Mainz-Kastel The Schmeckthal Group was rewarded with the Innovation Award 2009 for their development work on this tool. This Innovation Prize is awarded annually by the VTH Verband Technischer Handel e.V. and the Vincentz Network GmbH & Co. KG, editor of the trade magazine „Technischer Handel".

On October 2, 2009 the Managing Director René Schmeckthal proudly accepted the coveted award at the yearly convention of the VTH in Rust.

An application for legal protection of registered designs by the German Patent and Trademark Office of this cotter release mechanism was also submitted.
