This article summarizes our study made to obtain a super high-speed of 20, 000rpm in
spindle
revolutions of a ring frame, by improving the mechanisms of rotation parts such as
spindle
and ring, and by developing an advanced speed controller and speed regulator.
Our study for speeding up the
spindle
revolutions up to 20, 000rpm is as follows:
1) We have succeeded in developing a new
spindle
for ring frame, which can attain a speed of 20, 000rpm, putting the
spindle
vibration under restrain of the same level as in the conventional operation at 15000rpm.
2) All the bottlenecks of the rings and travellers usually encountered during the high-speed operation of
spindle
have been broken by imporving their mechanisms.
3) We have developed a speed regulators provided with wider ranges of speed and also a speed controller with lemient pitches to cause no sudden changes in speed. The new equipment thus developed increases the efficiency of
spindle
and is effective in eliminating yarn ends-down.
