Axial and radial bearing YRTM395 rotary table bearing with the angle measuring system
The series bearing is based on the YRT bearing; it is mounted with angle measuring system on the YRT bearing, in order to accurately measure and adjust the angle of the bearing rotating and make sure the high rotation speeds. Measuring system is composed of transmission chain and measuring scale.
It adopts pure inductive measurement principle, so the signal, its precision and the precision of measuring is very high.And by using high protective measures, the measurement system will be not disturbed in operation from external ambience, such as Smoke and Dust, mild pollution and scratches, magnetic field. I can work reliably without too much maintenance; the application scope is very wide.
It can be applied to high precision rotary table and axis rotation, index head, military radar, aviation, aerospace and the field with the high accuracy of Angle rotation in the measuring and the test.
Axial/radial bearings with integral measuring system comprise: axial/radial bearing YRTM with a dimensional scale and a electronic measuring system. The electronic measuring system contains two measuring heads, a set of shims and an electronic evaluation system.
Bearings of series YRTM correspond in mechanical terms to axial/radial bearings YRT but are additionally fitted with a magnetic dimensional scale. The measuring system can measure angles to an accuracy of a few angular seconds by non-contact, magneto-resistive means.
Advantages of the angular measuring system.
1.operates by non-contact means and is therefore not subject to wear
2.carries out measurement irrespective of tilting and position
3.has an automatically self-adjusting electronic system
4.has a self-centring function
5.is unaffected by lubricants
6.is easy to fit and the measuring heads are easily adjusted
7.there is no need for alignment of the bearing and a separate measuring system
8.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
9.does not give any problems relating to supply cables. The cables can be laid within the adjacent construction directly through the large bearing bore
10.ives savings on design envelope size and costs due to the compact, integrated design requiring fewer components.
