Description

This invention relates to a measurement technique.

The aim of the invention is to improve the accuracy of determining the amount of misalignment,

FIG. 1 shows a device for determining the magnitude of the misalignment of centers; in fig. 2 is a section A-A in FIG. one; in fig. 3 - design scheme. devices.

The device comprises a roller 1 with conical surfaces 2 and 3, the axes :: which are the same as the axis of the roller 1. On the outer surface of the roller 1 is fixed reading units 4 and. 5 in such a way that their measuring rods 6 and 7 are located in the same diametrical plane B perpendicular to the axis of the roller 1 opposite each other. The roller 1 has two spring-loaded lever elements 8 and 9, which are located in the roller 1 through through from the outer surface to the inner conical surfaces 2 and 3 of the guide grooves 10 and 11, which are made on opposite sides of the roller 1 axis. Lever elements 8 and 9 mounted on axles 12 and 13 located

equidistant from the axis of the roller 1 and the perpendicular diametral plane B. The measuring rods 6 and 7 interact with the large lines of the lever elements 8 and 9.

The device works as follows.

The device is installed in the tested centers 14 and 15 and the initial readings are recorded and at the reference nodes 4 and 5. Then the device is rotated 180 ° and recorded
