The invention relates to measuring equipment, namely to means for measuring deviations from the alignment of drive shafts, .- .., ..

The purpose of the invention is to increase the accuracy of determining the type of misalignment and increase the measurement performance by eliminating calculations.

The drawing shows a device for checking shaft alignment, general view.

The device for checking the alignment of the shafts consists of two attachment nodes 1 with base surfaces, two posts 2 fixed to the nodes 1, mounts in planes perpendicular to the base surfaces. A holder 3 s is rigidly attached at a 90 ° angle measuring indicator 4 arrow type. To the same stand 2, at an angle of 90 ° below the holder 3, a holder 5 is rigidly attached to which the two-arm lever 6 is hinged. One arm of the lever 6 is connected to the strut 2 by a spring 7, tending to push the lever 6 away from the strut 2. Other lever arm 6 is provided with a support pad 8 and an opening / through which an adjustment rod 9 passes, also connected to the second post 2 by means of a screw thread. The rod 9 is installed with a gap and is equipped with a nut 10. And a screw head 11. The measuring rod of the indicator: torus 4 is located coaxially with the arm of the lever 6 with the possibility of interaction with the supporting platform 8.-

The device operates as follows.

Before checking, we assume that the axis of the shafts are tilted relative to one another. The device is set up to determine the amount of shaft inclination, for which the rod 9 is screwed into the rack 2 until the two-arm lever 6 raises the support platform 8 until the gap between the hole and the rod 9 is visible. During the measurement, it is necessary to maintain gap. In the case of a large slope of the shafts, the setting must be repeated, increasing the clearance ..

Then the indicator readings are set to zero. The shafts with the device attached to them rotate together 180 °. According to the indicator, we determine the value of the shaft inclination in mm.

After eliminating the tilt of the shaft by installing the pads, they begin to determine the misalignment of the shafts in height. To do this, the rod 9 is twisted until a gap appears between the left part of the two shoulders lever 6 and the rod 9. In this case, the upper cut of the hole should lie on the rod9. Thus, the rod 9 can act on the indicator 4 directly. Set indicator 4 to zero. Turn the shafts with the device fixed 180 °. Based on the indicator, the thickness of the pads in mm is determined, which must be laid or removed.

To determine the shift of the shafts to the side, the device is placed horizontally, the indicator is set to zero and, turning the shafts 180 °, take a reading in mm.
