ATLANTA is pleased to announce their expanded range of Hardened & Ground Racks.
Further expanding their hardened & ground rack range, ATLANTA has added High-Precision (HPR) DIN 7 and 8 quality levels to provide more competitive price points to meet customer’s accuracy needs. These racks offer a convenient and economical alternative to the popular DIN 6 racks current on the market and are dimensionally interchangeable for a drop-in replacement.
ATLANTA is pleased to announce a new class of precision gear racks which offer several significant advantages over traditional gear racks. The StrongLine class of gear racks from ATLANTA utilizes an innovative carburized case-hardening process to increase the strength of the rack, including the tooth flanks and root, which maximizes its power density, stiffness and performance.
Because of the increased power density, a smaller rack size can often be used compared to traditional gear racks, or performance can be increased on existing systems.
ATLANTA is pleased to announce a new range of Precision Rack & Pinion Drive Systems that can handle highly dynamic and heavy loads. These systems utilize our Precision Planetary Reducers with an integral output housing and outboard bearing to provide a rigid support to the output pinion.
Typically, reducers with output flanges are limited in the forces they can transmit by the tilting moment that the output bearings can handle. By adding an output bearing housing, this limitation is removed. Also, the unique design of the pinion allows for smaller pitch diameters, which reduces the reducer torque. Because of these design enhancements, a smaller reducer can typically be used.
ATLANTA is pleased to expand their wide range of racks to include high-precision DIN 4 and 5 racks, which are precision manufactured in a controlled environment. Three levels of precision are now available, with pitch accuracies down to 0.012 mm per 1,000 mm length. This gives the machine designer the flexibility of choosing the desired level of rack precision to meet the application needs.
These racks are available in straight (spur) and helical versions, in modules 2.0 through 12.0, in half meter and one meter lengths. These racks are ideal for high accuracy applications requiring minimal pitch error over the complete travel length.
The high precision pitch of the racks can eliminate the need for electronic compensation and the high precision parallelism allows for drives with extremely low backlash without the need for preloading.
Used with our split-pinions, ultra-precise zero-backlash axis drives can be achieved.
ATLANTA Drive Systems, Inc. is pleased to announce a new range of ISO 9409-1 flanged pinions, which have compact designs to reduce the amount of drive torque required. Traditionally, flanged pinions have large pitch diameters which increase the amount of torque on the reducer they mount to.
With the new TR Pinion range, the pinion pitch diameters are significantly smaller, reducing the drive torque required and allowing a smaller reducer to be used.
This hardened & ground pinion range has a quality level of DIN 5 and is available in straight (spur) and helical-toothed versions, in metric modules 2.0 through 8.0. The pinions can mount to any reducers with ISO 9409-1 flanged connections, such as ATLANTA HT, Alpha TP, Stober PH, Apex AD and Neugart PLF. The pinions are easily mounted and replaceable if future repair is needed.
The combination of the TR pinions, with their low inertia and high accuracy, used with ATLANTA’s precision gear racks, make it possible to achieve very highly dynamic axis drives with high precision and repeatability.
We are pleased to announce the expansion of our range of Servo Reducers, now offering In-Line and Right-Angle versions in five levels of precision to meet any application requirements.
For applications requiring higher efficiency, we can now offer our Bevel-Gear (BG) Servo Reducers, which are available in three sizes with ratios from 4.75:1 to 9.25:1.
For applications requiring an in-line solution, we can now offer our Precision Planetary Reducer Series, available in eight sizes with ratios from 3:1 to 600:1 and backlash levels down to less than one arc-minute. This new series features HeliCamber® gearing which make them the most accurate and efficient planetaries available, with minimum wear, low backlash and low noise. Design features include mounting any servo motors (IEC, NEMA, or customized motors), standard low backlash, high torsional stiffness, 95 to 97% efficiency and quiet running.
To set the pitch in-between rack segments, a companion rack is typically used. While this works well for most applications, it can induce error into the axis. This error can accumulate with each rack joint, especially on long axis drives.
The assembly kit consists of a measuring bridge, an adjusting device and magnetic rollers. With this kit, it is possible to achieve perfect rack joints without adding error to the system.
