CR2000 Heavy duty rotary table

Flat heavy duty ring with large central opening. A real powerhouse. Freely programmable. The flat design saves space and offers flexibility for creating ergonomically sound workplaces. Using the W.A.S. control system, the ring is completely freely programmable.

TECHNICAL DATA
. Max. motor speed: 2000 1/min
. Max. output speed: 6.5 1/min
. Overall gear ratio: 310
. Indexing precision: 20 arcsec (± 10”)
. Axial run-out of the drive flange: (at Ø 1874 mm) 0.03 mm
. Concentricity of the output flange: 0.03 mm
. Total weight, including motor: approximately 3600 kg
The values stated for axial run-out and concentricity can only be achieved with precise mounting surfaces.

LOAD DATA (for the output flange)
. Permitted dynamic tilting moment: 55000 Nm
. Permitted dynamic axial force: 250000 N
. Permitted dynamic radial force: 125000 N

Application Example

Application Example

Large tables, small waves
Positioning accuracy smaller than 0.01 degrees: CR heavy duty rotary indexing ring replaces gear rim drive in positioning system.

 

Challenge
Maturo specialises in positioning systems for EMC and radio measurements. The company required a new drive for a rotary table for measuring the electromechanic compatibility of vehicles as the old, complex gear rim pinion drive was not precise enough for the desired positioning accuracy of 0.01 degrees.

 

Solution
The high degree of positioning accuracy was one of the main reasons why Maturo chose to make the switch to the CR?2000 heavy duty table. Further arguments in favour of the new system are user-programmability, a large central opening and an extremely high permissible mass moment of inertia. The rotary table with a diameter of 14 metres and a total weight of 25 tonnes was needed for handling a mass moment of inertia of 1,000,000 kgm2. Fixed castors attached to the perimeter bear part of the weight, while an additional transmission fitted between the drive and the table guarantees better controllability. In addition, modifications make it possible to use the solution outdoors for the first time.
