The embodiments described below by referring to the drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.

The embodiment of the utility model provides a: the utility model discloses a shaft coupling centering calibration mechanism, mainly used centering calibration after the shaft coupling is connected, after the shaft coupling with driving shaft and driven shaft installation butt joint, generally need driven shaft and the coaxial setting of driving shaft, can realize the synchronous rotation of driving shaft and driven shaft when driving shaft drive shaft coupling and drive the driven shaft and rotate to can avoid the driving shaft to appear swinging or rock at the transmission in-process. Especially for equipment running at high speed, the running stability and the service life of the equipment are seriously influenced by the misalignment of a driving shaft and a driven shaft connected with a coupling.

Whether shaft coupling centering aligning gear is used for calibrating driving shaft and driven shaft and has the deviation in this embodiment, the inaccurate problem of centering of discovery driving shaft and driven shaft that can be timely to the use of better realization shaft coupling.

As shown in fig. 1 to 6, the coupler centering calibration mechanism disclosed in this embodiment includes a pair of centering assemblies 1 disposed oppositely, where the centering assemblies 1 include a fastening member 11 for being fixedly connected to a shaft 100 and disposed coaxially with the shaft 100, and an alignment mark 12 disposed on the fastening member 11.

The fastener 11 is used for fixing the centering calibration mechanism on the shaft 100, it should be noted that the shaft 100 may be a driving shaft or a driven shaft, in this embodiment, two centering assemblies 1 in a pair of centering assemblies 1 are respectively fixed on the driven shaft and the driving shaft, and then whether the driven shaft and the driving shaft are centered is judged through two alignment parts 12 on the two centering assemblies 1, so that the centering calibration of the driven shaft and the driving shaft is realized.

In the present embodiment, the fastening member 11 has an axial direction and a radial direction arranged perpendicular to the axial direction, and since the fastening member 11 is fixed to the shaft, the axial direction of the fastening member 11 is parallel to the axial direction of the shaft, and the radial direction of the fastening member 11 is parallel to the radial direction of the shaft.

The pair of standard parts 12 extends along the radial direction of the fastener 11, and a centering surface 121 is formed on one side of the pair of standard parts 12 facing the other centering component 1.

The misalignment of the driven shaft and the driving shaft mainly comprises the following two conditions in the actual use process, wherein the first condition is that the driving shaft and the driven shaft are mutually staggered in the axial direction but are in a parallel state in the axial direction, the bottoms of the alignment parts 12 are butted together in the state, and after the bottoms of the alignment parts are butted together, whether the tops of the alignment parts 12 are overlapped together or not is judged so as to judge whether the misalignment occurs or not.

Of course, in other embodiments, the above problem may be determined by first butting the tops of the targets 12 together and then observing whether the bottoms of the targets 12 can be butted together.

In the present embodiment, the calibration target 12 is arranged to extend in the radial direction, which substantially amplifies the misalignment of the driving shaft and the driven shaft in the axial direction, and the misalignment can be more efficiently detected by the calibration target 12.

In the practical use process, another condition of inaccurate alignment exists after the driving shaft and the driven shaft are in butt joint, and the axial direction of the driven shaft is not parallel to the axial direction of the driving shaft in the condition, namely the problem that the driving shaft or the driven shaft is tilted exists.

In order to solve the above technical problem, in the present embodiment, the centering surface 121 is provided on the calibration part 12, and whether there is a shaft warpage problem can be determined by observing whether the centering surfaces 121 on two opposite calibration parts 12 can be attached to each other. The extension of the target 12 in the radial direction, if there is a warpage of the shaft, enables the warpage to be magnified and observed through the gap between the two centring surfaces 121.

This application can be more high-efficient audio-visual the centering of realization driven shaft and driving shaft through two settings to mark piece 12 judge.
