Coaxiality alignment method for connection between transmission shafts of two sets of equipment through connecting discs

Abstract

The invention provides a coaxiality alignment method for the connection between transmission shafts of two sets of equipment through connecting discs, which relates to the technical field of mechanical transmission. The coaxiality alignment method includes: step 1: at a certain point on each connecting disc, gaps and edge height differences corresponding to the points are measured by at least two rotation angles; step 2: according to the measured data, whether the data difference meets the requirement is judged; if not, then the two sets of equipment are aligned, and step 1 is repeated; and if so, then the process is finished. The coaxiality alignment method can truly correct the coaxiality error of the transmission shafts (linkage shafts), and still can ensure that the two adjusted transmission shafts are almost coaxial even if the perpendicularity between the connecting discs and the linkage shafts is not enough or the axes of the connecting discs and the linkage shafts are not coaxial, thus reducing transmission noise and the abrasion of the transmission shafts, prolonging the service life and reducing power loss in transmission.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a coaxial centering method when two equipment transmission shafts are connected through a coupling plate. Background technique [0002] In daily work, it is often encountered that one device needs to be driven by another device, and in order to save space, the output shaft of the active device needs to be directly connected to the input shaft of the driven device. At this time, the transmission shafts of the two devices are required to have a certain degree of coaxiality to reduce noise and power loss during transmission. [0003] In the prior art, the coaxiality alignment method of the two transmission shafts is: by measuring the coaxiality of the two coupling discs to judge the coaxiality of the coupling shaft (that is, the transmission shaft), that is, the coaxiality of the coupling discs is used instead of the coupling Shaft concentricity. There are two spec...

Problems solved by technology

[0007] The inventor of the present application has found through painstaking research that the above two methods have the following disadvantages: they do not directly measure and adjust the coaxiality of the two coupling shafts, but indirectly replace the coaxiality of the coupling shafts with the coaxiality of the coupling disc

The effective premise of this method of adjusting the coaxiality is that the coupling disk and the coupling shaft must be coaxial; image 3 The coupling disc and coupling shaft shown on the right are not perpendicular enough or as Figure 4 There is a deviation in the coaxiality of the coupling disc and the coupling shaft shown on the right, which will cause the coaxiality of the two coupling shafts to be out of the required range even though the coaxiality of the two coupling discs is well adjusted situation (such as image 3 and Figure 4 shown)

This is also the reason that although some equipment thinks that the coaxiality is well adjusted, the equipment still has a large noise or the coupling shaft wears out quickly.

In reality, there must be errors in the verticality and coaxiality of the coupling disc and the coupling shaft.

From the above analysis, it can be seen that there are certain defects in the coaxiality alignment method in the prior art
