Description

Backing bearing contour measuring instrument

Technical Field

The utility model belongs to the field of detection, and particularly relates to a backing bearing equal-height measuring instrument.

Background

The multi-roller cold rolling mill is widely used for rolling mills of high-precision steel and nonferrous metal strip steel. As the requirements for flatness, thickness tolerances and surface quality of the rolled product continue to increase, higher and higher requirements are placed on backing bearings for multi-roll cold rolling mills.

The backing bearing is a bearing which is mounted in groups on a stationary shaft as a backup roll when used with a particularly thick outer ring. The pressure on the work rolls is transferred through the intermediate rolls to the backing bearings (support rolls) and through the saddle system to the frame.

The backing bearing is generally a multi-row cylindrical roller bearing, the precision required by the bearing is very high, and particularly the section height from the inner diameter to the outer diameter (also called as T value) after eliminating radial play is particularly important, and the T value is controlled within 0.005mm on each shaft, so that the precision of the backing bearing part is required to be very high.

The backing bearing has certain difficulty in carrying and adjusting during T value detection because of the extremely thick bearing outer ring, which always plagues manufacturers.
