Description

Technical Field

[0001] The utility model relates to the technical field of couplings, in particular to a centering structure of a coupling with a brake wheel. Background Art

[0002] A coupling is a mechanical part used to connect two shafts (driving shaft and driven shaft) in different mechanisms so that they rotate together to transmit torque. Alignment is a key step in the installation process of couplings. Poor alignment may cause unstable operation of the coupling, excessive noise, and even accelerate the wear and damage of the coupling. By accurately aligning the shafts, it can ensure that the coupling can smoothly transmit torque during operation and minimize the risk of failure caused by misalignment.

[0003] The existing method for coupling centering adjustment usually uses a ruler and a feeler gauge to measure the radial displacement of the two couplings, and uses a plane gauge and a wedge gauge to measure the axial position of the two coupling parts, so as to measure the upper, lower, left and right directions of the two coupling parts respectively, and finally adjust the two coupling parts according to the measurement results to align the two coupling parts. However, a coupling with a brake wheel is a special coupling installed on a belt conveyor or crane equipment. A brake wheel is fixed on the coupling, so that the space for measurement on the coupling part is only the distance between the brake wheel and the coupling part. The space is small, and the existing method for coupling part centering adjustment cannot be used to perform centering adjustment.

[0004] The utility model patent with application number 202420654348.1 discloses a centering structure with a brake wheel coupling, which includes a base, a slide rail is installed on the upper surface of the base, a slider is installed inside the slide rail, a mounting plate is connected to the outer surface of the slider, two movable plates are vertically penetrated inside the mounting plate, a bottom plate is installed at the bottom of the movable plate, a thimble is installed on the lower surface of the bottom plate, two fastening bolts are installed on the side surface of the mounting plate, and the two fastening bolts correspond to the two movable plates respectively, and a top plate is installed on the top of the movable plate. The base is placed on the surface of the coupling shaft, and the two thimbles are respectively vertically pressed against the two sleeves, and then the two fastening bolts are tightened in sequence to fix the position of the movable plate, and finally a vernier caliper is used to measure the distance from the upper surface of the top plate to the lower surface of the mounting plate. The height difference between the two sleeves can be obtained through the difference between the two sets of data, which is convenient for centering adjustment. This application has a slider installed inside the slide rail for sliding, and the outer surface of the slider is connected to a mounting plate. The slider can slide freely inside the slide rail. Because there are more or less errors in the processing process, in order to make the slider slide freely inside the slide rail, there must be a certain gap between the slider and the slide rail, which produces a large vertical movement at the end of the mounting plate, making the measurement inaccurate; after the measurement is completed, it is necessary to tighten the two fastening bolts, directly slide the mounting plate up, so that it drives the slider to be pulled out from the inside of the slide rail, and then use a vernier caliper to measure, which is a cumbersome operation.
