Worm gears


Worm gears

We are producing various designs of worm gear sets according to customer drawings with all common standard profiles.In cooperation with the CAVEX GmbH & Co. KG company we are offering the CAVEX® wheel set program – a proven and established program of worm gear sets.Due to their power density and the long service life CAVEX® wheel sets are for experienced designers of demanding machines and plants such as

  • Packaging machines
  • Food machines
  • Strip mills (scissors, reels, roller tables)
  • Mixing and stirring equipment
  • Shipbuilding

always the first choice. The DUPLEX wheel set has been well-proved in applications with higher accuracy and stiffness requirements. In this case the worm is designed with a variable pitch which allows to regulate the wheel set free from play. So the conditions for a highly precise manufacturing are fulfilled. The CAVEX® tooth profile is decisive for the long service life and the high loading capacity of the wheel sets. Due to the concave-profile the material properties of the high quality bronze of the wheel and the cased-hardened worm can be fully taken because of the reduced flank pressure and the improved lubrication in every operating condition. Due to the concave profile a very large tooth base thickness is achieved on the worm. Therefore, the wheel sets are very insensitive to large impact loads at low speeds. The manufacturing range of CAVEX® gear wheel includes:

  • Axle distance 40 – 1400 mm
  • Gear ratios 1 to 180
  • Module 1 to 40
  • Number of teeth on a worm – 1 to 12
  • Increased accuracy
  • Limited flank play
  • Finished measurements according to customer specifications
  • Special models

CAVEX® wheel sets are optimized with the most modern calculation tools and designed for highest loads. The reliability of CAVEX® gear wheel sets have got a high weight in rough operating conditions. We thoroughly persuade of each gear wheel set. After the geometric testing of the worm and wheel the wear pattern is checked.
