KTR: Settings things in motion

KTR Couplings (I) Pvt. Ltd., which is a 100 per cent subsidiary of KTR Systems GmbH, Germany, is one of the well-known names in couplings & power transmission products. KTR established in 1959, with headquarters in Rheine, Germany, has subsidiaries in over 23 countries with 7 manufacturing plants in Germany, USA, Poland, Brazil, China, India & Taiwan.

KTR India, established in 1998, has a manufacturing plant at BHOSARI, PUNE, with full-fledged manufacturing set-up, and caters to the coupling needs of every industrial sector. We manufacture variety of couplings and transmission products for all types of conceivable drive applications. Apart from couplings, we also supply hydraulic components, clampex, universal joints, torque limiters and torque measuring equipment, hydraulic & electro-mechanical break systems, and oil/air/ water cooling systems.

Automation technology has to meet with contradictory demands: speed and accuracy, flexibility and reliability, and highest efficiency combined with highest profitability. It is good to see that KTR couplings are as multi-purpose as their applications.

For feed drives in machine tools, gantry robots or other handling units driven by servo motors, accurate positioning with at the same time full dynamics is important. The selection of coupling has a decisive influence on behavior of overall system. KTR offers you four different types of backlash-free couplings: jaw coupling (Rotex GS), servo lamina coupling (Radex NC), metal bellow-type coupling (Toolflex) and special coupling for shaft encoders (Countex).

Positional technology
The back lash free flexible jaw coupling ROTEX GS has proven its worth in the positioning technology and on main spindle drives. In spite of its damping vibration feature, it is sufficiently and torsionally stiff so that even with highly dynamic servo drives accuracy does not suffer. This is why it is said to be the standard solution for ball screws with inclines S < 40. Clamping ring hubs are suable for circumferential speeds up to 50 m/s.

Rotex GS P was developed by KTR in cooperation with VDMA (Association of German Manufacturers of Machines and Plants) to be used on the stub spindles of multiple spindle heads. Integrated clamping system of back lash free, and highly precise shaft coupling is made of 100 per cent steel. With circumference speed of 75 m/s and higher, it is ideally suited for applications on HSC main spindle drives. ROTEX GS P is manufactured to DIN 69002.

The backlash-free metal bellows-type coupling TOOLFLEX with a non-positive connection of bellow and a hub and a frictionally engaged clamping hub is suitable for temperatures up to 280C. For higher inclines, S = 40 Toolflex coupling is recommended; it remains fatigue and is endurable in high temperature up to 200C. Its main application ranges are both positioning drives e.g. ball spindles with high incline and indexing tables or planetary and work gears with small gear ratios.

RADEX NC is developed for servo technology. Stainless steel laminas make it torsionally stiff and at the same time flexible. Aluminum hubs ensure a low mass moment of inertia even with double cardanic design.
