Why our couplings are No1 in market : The function of every
flexible coupling is to transmit power or motion control from
one rotating shaft to another that is not perfectly aligned,
without excessive bearing loads. But since the requirements
for transmitting power are not the same as they are for controlling
motion, couplings designed to transmit power might well be
unsuitable for motion control and vice versa. For instance,
a resilient coupling made with rubber or springs would work
well delivering power because it could absorb vibration and/or
shock loads, but would not work well controlling motion. In
a motion control system, every component in the drive train
(including couplings) affects the accuracy of the system by
the amount of compliance (Wind-Up), Inertia, Friction, Backlash,
etc. the things, which are quite unimportant when transmitting
power. A coupling that absorbs vibration must by definition,
have Wind-Up, Inertia, or Backlash. Whereas a true motion control
coupling must have no Backlash, low Inertia, and very low or
zero Wind-Up. Here's what may happen in a typical servo system
- Closed Loop, Open Loop, PID Loop, Feed Forward, or what ever:
Delay caused by Wind-Up, Inertia, or Backlash. The system must
also be free from imbalance, vibration, and oscillation in
order to prevent hunting - especially in closed-loop systems
where a null balance is established between error signals.
Since 1994 MICRON has been building and improving Servo and
Encoder Couplings that provide reliability and long life free
from maintenance - at moderate cost.
