    These racks have the teeth at an angle (19º 31' 42") to rack length for increased load capacity and quiet operation.

    These racks have the teeth perpendicular to rack length, and are traditionally known as "spur".

    These racks were designed for mounting directly to most common linear guides.

    These racks have a round cross-section and use bushings for support.

  • Advantage of long, ground racks of ATLANTA

    For mounted racks, the obtained accuracy and required installation time are important. With ATLANTA ground racks with lengths of 1 500 mm and 2 000 mm, the total pitch error per meter is reduced dramatically. Thus, the pitch error of the entire axis is correspondingly lower. By using long racks, the number of rack joints is reduced, which improves the accuracy of the entire axis and significantly reduces the installation time at the same time.

    Ground racks have the advantage that the complete rack is more precise, the meshing takes place evenly and the pinion bearing stress is reduced unlike a milled tooth. The ground rack drives have lower friction which increase energy efficiency.

    Assembly Example:

    The following example shows the advantage of long, ground racks of ATLANTA.

    Assembly of module 4 racks.

    • Assembly length: 6 meters mounted with companion rack for assembly i.e. Qjoint = 25µm
    • Time: Number of screws x tscrew + number of joints x tjoint + number of pins x tpin

     

    2m_Zahnstangen

    It will be used 3 pices of 29 40 205 quality 6, helical toothed, module 4, length 2 000mm :

    • Accuracy GTf/2 000 = 47µm
    • Maximum pitch error: 3 x 47µm (racks) + 2 x 25µm (joints) = 191µm
    • Time: Number of screws = 3 x 16 = 48 screws, number of joints = 2, number of pins = 0

     

    1m_Zahnstangen

    It will be used 6 pices 29 40 105 quality 6, helical toothed, module 4, length 1 000mm :

    • Accuracy GTf/1 000 = 36µm
    • Maximum pitch error: 6 x 36µm (racks) + 5 x 25µm (joints) = 341µm
    • Time: Number of screws = 6 x 8 = 48 screws, number of joints = 5, number of pins = 0

     

    0,5m_Zahnstangen

    It will be used 12 Stück 29 40 055 quality 6, helical toothed, module 4, length 500mm :

    • Accuracy GTf/500 = 32µm
    • Maximum pitch error: 12 x 32µm (racks) + 1 x 25µm (joints) = 659µm
    • Time:  = 12 x 4 = 48 screws, number of joints = 11, number of pins = 12 x 2


    Advantages of using long, ground racks of ATLANTA:

      • Reduced pitch error values
      • Reduced number of rack sections required
      • Reduced the number of rack joints
      • Reduced amount of time needed to mount the racks

Integrated Racks

ATLANTA Integrated Racks are suitable for a wide range of applications where precise positioning and repeatability is required. Due to the direct mounting on the rail, the adjusting between rack and rail eliminates. Thus, space-saving and performance-optimized structures can be realized.
