Tandler gearboxes were originally developed to meet the exacting standards of the printing industry, and its latest offering for this sector will feature at Drives and Controls 2002.
Tandler gearboxes were originally developed to meet the exacting standards of the printing industry.
As the accuracy of the gearing through a printing press is directly related to quality of the printed product, this application remains the company's benchmark today.
Indeed one of the new developments on the company's stand at Drives and Controls 2002 is again aimed at this sector.
This new addition is a special speed modulation gearbox for flexographic printing.
Twin output shafts allows the separate phased control of both plate and impression cylinders on a printing press resulting in high accuracy, consistency, reliability and even better print quality.
This gearbox joins the established and comprehensive range of high precision options available from Tandler, a generous selection of which will be shown on Stand C50 at the show.
As well as other speed modulation examples, exhibits include new sizes of spiral bevel gearboxes with hollow shaft, switch and reverse operation and auxiliary branch-off shaft; servo gearboxes designed to interface with the majority of servo motor brands in both metric and imperial sizes; and in-line planetary gearboxes offering ratios up to 1000:1.
Also being introduced by Tandler at Drives and Controls is the new R+W LK linear coupling which accommodates 0.7mm of parallel misalignment and 1.5 degrees of angular misalignment.
It exhibits zero axial backlash under all operating conditions and provides a virtually limitless service life.
The LK linear coupling is designed for high dynamic applications with accelerations up to 300m/s2, and high loads of up to 500N.
This product is ideal for connecting any linear positioning sensors, linear motors, actuators, electric and pneumatic cylinders and as a replacement for actuator rod ends.
Offering a wide torque range of 0.1 to 10,000Nm, the R+W coupling range generally falls into four basic groups - the MK miniature bellows series, the BK bellows series and the comparatively new Servomax range of servo insert couplings.
The final group - SK - comprises backlash-free safety couplings or torque limiters.
All models are balanced up to 10,000rev/min, although applications of 40,000rev/min have been ably met by the R+W range.
They accommodate misalignment in three planes, offer zero backlash with high torsional stiffness and are suitable for operation in the temperature range of -30 to +120C.
Examples of each of these models complete the stand display.

Other Tandler Precision stories
-
Torque limiters keep it clean
The R+W SK range of torque limiters is characterised by its highly compact and uncomplicated design, patented backlash-free operation and millisecond disengagement. -
Redesigned gearboxes boast twice the torque
The new PowerMaster gearboxes are available in three sizes with maximum torques of 300, 640 and 1200Nm and in three ratios per size of 1:1, 2:1 and 3:1. -
Smaller torque limiters promise longer life
The latest generation of R + W torque limiters from Tandler Precision are more compact, weigh less and deliver an even longer service life than their forerunners. -
Elastomer couplings cope with sudden loads
The major advantage of R+W elastomer couplings is that they transmit high torque with no backlash while accommodating misalignment and dampening vibration. -
Gearboxes and couplings gain ATEX approval
Several types of Tandler's spiral bevel gearboxes and couplings are now ATEX rated.
