  Rotary tables and trunnion drives with fixed steps of the EDX series

  Design and function
  EXPERT-TάNKERS precision rotary tables convert constant drive movements into indexed output movements.
  Due to the construction of the cylindrical cam profiles in accordance with mathematical laws on curves,
  a smooth and shockless motion sequence is generated. When in operation, the cam effects a stepwise rotation of the table by the defined angular displacement per step.
  A form-closed positioning of the table plate with low-backlash, high-precision fit is achieved in the dwell position, without any additional locking mechanism.

  Laws of motion
  Index drives which must accelerate and decelerate inertial masses from resting positions, are required to produce smooth and shockless motions.
  Here the law of motion suited for the customer application, for instance modified sines, is applied.

  Series features

  Housing
  • Newly dimensioned compact housing, processed according to standards, for improved and easy centring and orientating of rotary tables.
  • Openings are provided in the centre and on the sides for the installation of supply lines.

  Cylindrical cam profile
  • Hardened and ground for low-vibration motion and long service life.
  • Inspection, assembly and disassembly via opening on the side of the housing.
 
  Cam followers
  • Hardened and ground.
  • Inspection, assembly and disassembly are directly possible from the top of the table plate (openings in the tooling plate are to be accordingly provided for)
  • Cover plates for protection of the cam followers.
 

  Table plate
  • Newly dimensioned table plate with enhanced performance data.
  • Due to the arrangement of the table plate and ball bearing,
  no supplementary covers are needed to protect the bearing (contact with spatter, water, dust can be avoided under normal   environmental conditions).
  • The table plate is prepared to accommodate corresponding centring bushings.
 

  Ball bearing
  • Quality bearings especially tailored to meet EXPERT-TάNKERS requirements.
  • Inspection and adjustment possibilities from outside, with loaded tooling plate (no disassembly required).
 

  Drive
  • The rotary table is driven by an energy-saving three-phase motor.
  • Optional operational modes: One or two speeds, one direction of rotation (right or left), two directions of rotation (reversing).
 

  Control

  Our new ‘intelligent’ SmartTurn system, is used as a standard control for rotary tables with fixed divisions.
  The new generation of rotary tables is optionally supplied with an inductive switch and the stand-alone Smart-Turn control system,
  which replace the complex mechanical switching devices and fully control the table.
