Integrated Angular Measuring System (TPI 154) for Torque Motor Axes
Axial/radial bearings with integrated measuring system for torque motor axes comprise: an axial/radial bearing YRTSM with a dimensional scale, an SRM electronic measuring system and the signal cables. The electronic measuring system comprises two measuring heads, two shims and an electronic evaluation system. Bearings of series YRTSM correspond in mechanical terms to axial bearings YRTS but are additionally fitted with a magnetic dimensional scale on the shaft locating washer.
The measuring system can measure angles to an accuracy of a few angular seconds by non-contact, magneto-resistive means. For the mechanical part of axial/radial bearings YRTSM, please refer to the information in the catalogue Rolling Bearings, HR 1 and Technical Product Information TPI 120.
The measuring system: operates by non-contact means and is therefore not subject to wear, carries out measurement irrespective of tilting and position, has an automatically self-adjusting electronic system, has a self-centring function, is unaffected by lubricants, is easy to fit, the measuring heads are easily adjustable, there is no need for alignment of the bearing and a separate measuring system, requires no additional parts – the dimensional scale and measuring heads are integrated in the bearing and adjacent construction respectively.
The resulting space saved can be used for the machining area of the machine does not give any problems relating to supply cables. The cables can be laid within the adjacent construction directly through the large bearing bore, gives savings on design envelope size and costs due to the compact, integrated design requiring fewer components.
