The new docking system helps increase the efficiency of engine test bench<br />
The new adaptive docking system from Reich-Kupplungen helps<br />
automate the process of changing the test objects for engine testing<br />
to the greatest possible extent and thus enables a significant<br />
increase in the efficiency of engine test bench operations. The<br />
system was showcased for the first time at the this year’s Automotive<br />
Testing Expo in Stuttgart. The visiting vehicle<br />
manufacturers and component suppliers, were<br />
impressed with the self-docking and self-centering<br />
fixture. It consists of 2 standard components - a<br />
transverse pin and a sleeve which are both straighttoothed.<br />
Rigging only involves the mounting of the<br />
matching coupling with the pin to the engine. Given<br />
that this work is performed outside the test bench area, the rigging<br />
times are minimized in the test cell. This fixture allows for preparing<br />
other engines to be tested while one engine still undergoes<br />
testing. The basis is a correctly positioned, solid support on which a<br />
CV-jointed sleeve is placed. While the engine with the mounted<br />
coupling and the toothed pin is approaching its<br />
destination, the sleeve is lifted and turned until the<br />
toothed components come into mesh. All toothed<br />
shaft components come into mesh in any turning<br />
position to maintain a good balanced condition.<br />

Low-friction ball<br />
bearings increase<br />
energy efficiency<br />
Low-friction ball bearings in the<br />
drive system increases energy<br />
efficiency and reduces operational<br />
noise and heat generation,<br />
which in turn helps to extend the<br />
service life. Based on optimized<br />
raceway geometry and special<br />
sealing concepts, NSK has<br />
developed several series of ball<br />
bearings that offer significantly<br />
lower friction characteristics.<br />
The new bearings feature a<br />
proprietary geometry that<br />
reduces the contact surface<br />
between the balls and raceways.<br />
Its fiber-glass-reinforced<br />
polyamide cages and high-performance<br />
lubricants contribute<br />
significantly to lowering the<br />
frictional torque. Its production<br />
process is another important<br />
factor, since any roughness in<br />
the bearing raceway is likely to<br />
impair lubrication, increase<br />
running noise and generate<br />
greater friction. Therefore, the<br />
raceways of NSK ball bearings<br />
undergo a bespoke honing<br />
process that is designed to<br />
deliver an extremely smooth<br />
running surface. In regards to<br />
seal technology, the non-contact<br />
labyrinth design developed and<br />
patented by NSK ensures<br />
efficient sealing properties<br />
without increasing frictional<br />
torque or operating temperature.<br />
This is vitally important in<br />
applications where any loss of<br />
performance is deemed to be<br />
particularly detrimental.<br />
