Structure introduction

the Austria AMOSIN steel grade measurement system including three parts:steel grade feet, reading-head and electronic assessment. the steel grade feet was installed on the inner ring of the bearing(figure 2), it is a steel ring with grids uniform distribution on. the reading-head was installed on the outer ring of the bearing (figure 1), it is near the steel grade feet, but not touch, there is a 0.1–0.2mm clearance between them.

When Working, the bearing rotary, the steel grade feet and the reading- head (figure 3) do non-contact relative motion, then turn the the data wich was collected by induction to the electronic evaluation  (figure 6) through the cable (figure 5). The electronic evaluation then transfer the information to square wave or Positive harmonic signal. these signal was put into the numerical control system In the machine tools, to realize the measuring and control to the angular displacement.

Advantage of the steel measuring system:

A. No- contact inductive encoder, no wearing.

B. the precision can compare to the optical encoder, high precision<2 arc-second

C. Double reading-head measuring system can correct the deviation on  bearing radial in real time.  

D. High speed, high dynamic resolution, high dynamic performance.

E. No magnetic components, no hysteresis reaction, no demagnetization dangerous

F. Strong anti-jamming to solid grain, oil etc. Protection grade IP67, resistance to water pressure and dense dust, not sensitive to any type of dirt and pollutants.

G. Compact design, no matter for narrow installation space.

H. Easy for installation, high speed for adjustment, high resistance to impact and vibration, good stability, high reliability

I. Can output sine wave (1VPP) and square wave signal (TTL), compatible with Siemens and Fanuc numerical control system, etc

3. Application parameters

AMOSIN steel measuring system has many different kinds of configuration, we can offer the best solution according to your requirement.

*X*When order, the buyer should provide the following information of location accuracy rotary speed for real-time working, the length of the cable, the kinds of the  signa l output, number, the number and type marked on the reference point.

the steel grade feet divided into three precision grades of +-3 μm (Arc length), +-5 μm(Arc length), +-10μm(Arc length).

Stander for reference points mark: every 360 degrees. We can do as clients’ actual application: more reference points mark

Signal output type: IVPP or TTL

*X* for other specification of YRTM rotary table bearing, please contact with HONGYUAN.

4. Installation guide

the installation method is the same as the standard YRT bearing, (please reference chapter three: Design and installation guide)

for YRTM rotary table bearings with integral measuring system. the measuring system was installed on the bearing and adjust to the best before ship. You can be installed and to be use after receipt, no need to be  re-adjusted.  

5. Special design

Avalible by agreement. for the special dimension, reference points, the space of reader head, the length of the cable, please contact with HONGYUAN.(HONBbearing02)
