In certain applications are Lead Screws an extremely economical alternative for the more precise Ball Screws. Dr. Tretter has now included them in its broad product portfolio and covers a very wide range of diameters and pitches with the trapezoidal thread spindles.

Trapezoidal screw drives consist of the Acme screw and an Trapezoidal screw nut. A high degree of strength can be achieved by rolling the trapezoidal thread spindle. If the thread flanks also have a high surface quality, the unit achieves extremely good running properties.

Wide range of modular rail guides

Trapezoidal thread spindles are used in Machine tools, CNC technology or feed units, Automation or handling. However, designers also install them efficiently in manual adjustment units. Another advantage is the small space requirement of the trapezoidal screw drive.

End machining of the trapezoidal thread driver on customer request

Dr. Tretter is on that End machining of the screw drive according to customer drawings for small or large quantities. The standard length of the spindle is 3 m, the maximum length is 6 m. The provider's expertise lies primarily in the cost-effective processing of small and medium-sized quantities. Upon request are also Special Materials and special Surfacestreatments is possible.

The connection of a trapezoidal thread spindle to the Drive journal one Motors or Transmission As a rule, this is not done rigidly, but rather via a flexible coupling. In this way, center offsets or misalignments can be compensated for and vibrations and shocks can be eliminated Powertrain be minimized.
