Problems solved by technology

Another problem is that these instruments are manufactured with large tolerances, so angular misalignment measurements become very inaccurate due to backlash
The prior art of this document involves swivel joints, which must be mounted in place along the support

Embodiment Construction

[0025] FIGS. 1-4 show a first machine or first machine part 30 with an axle 34 on a first base 32 and a second machine or second machine part 31 with an axle 35 on a second base 33 . The shafts 34, 35 of the two machines 30, 31 are substantially parallel with respect to their axial orientation, but in one of the two spatial directions, the two shafts are along a longitudinal axis perpendicular to the two shafts 34, 35. offset relative to each other in one direction. Accordingly, at the end of each shaft 34, 35 there is a universal joint 36, 37, respectively. The two cardan joints 36 , 37 are connected to each other by means of a third shaft 38 .

[0026] As we all know, in order to realize the correct operation of the unit formed by the three shafts 34, 35 connected to the two universal joints 36, 37, two conditions must be met: first, the two forks of the universal joint are in the third The axis 38 lies in one plane, and secondly, the angles on the two universal joints 36,...

Abstract

A device for measuring and optionally correcting the angular offset of two shafts which are connected to one another by way of two universal joints and a third shaft calls for the measurement heads of an optoelectronic alignment device to be adjustably arranged on the shafts by means of at least one pivot joint on one of the clamping devices, with an adjustment capacity. A pertinent method contains matching of the orientation of the measurement heads of the optoelectronic alignment device on the shafts in at least two measurement positions by adjusting the pivot joint.

Description

[0001] This application is a Chinese invention patent application titled "A device and method for determining the orientation of two shafts connected by two universal joints and a third shaft with a rotary joint" with a filing date of November 8, 2012 Divisional application of 201210444231.2. technical field [0002] The invention relates to a device and an improved and simplified method for determining and correcting the angular misalignment of two axes of a machine or a machine part which, due to their parallel misalignment, pass through two universal joints and connect them The third axis is interconnected. Background technique [0003] In the past, offsets between the two shafts connecting the motor and the driven machine to each other were compensated by means of two cardan joints and a third shaft. However, this configuration can only compensate for parallel deviations. If the two axes are not aligned exactly parallel to each other, severe damage usually occurs due t...
