Couplings are intermediate parts that connect the motors of general machinery and equipment with bearings or two shafts. The coupling has high torque rigidity, zero backlash, and elastic body compensation for the radial and axial generated by the two shafts during the transmission process of manufacturing machinery. , Angular deviation, clockwise and counterclockwise rotation characteristics are equal. It makes a major contribution to papermaking, metallurgy, textiles, shipbuilding, agricultural machinery, transportation, chemical, light industry and other industries. The end face processing of the coupling is often set in This is done on the shaft, so that the tenon on the end face of the coupling can be accurately concentric with the axis. In this machining process, special attention should be paid to ensure that the end face of the coupling is perpendicular to the rotor shaft, and attention should be paid to the alignment of the tenon Whether the mutual cooperation meets the requirements.For flange couplings without centering tenon, the two half couplings should be sleeved together for reaming after drilling.

　　(1) There are problems such as whether the sealing of the lubricating series oil is intact, the oil is deteriorated, and the oil leaks out.When the above situation occurs, the seal and oil need to be replaced. When the oil is lacking, it needs to be replenished as soon as possible.

　　2) Gear-type safety inspection: It needs to be removed for inspection when the transmission noise increases or the product is overhauled.

　　(3) Inspection of the elastic coupling: When the rubber ring and the leather pad are damaged, they need to be replaced as soon as possible. If the pin or the hole is destroyed and vibration occurs, it is necessary to rotate the half body at an angle Drill the hole once and replace the standard new pin. It is not possible to expand the original hole with a new pin.

　　(4) The basic requirements for its inspection: the connection must be stable, the connecting bolts and connecting keys must not be loosened, and the radial and end surface jumps in the transmission should not be obvious when viewed visually. , When using the instrument to check, it cannot exceed the limit.
