The end face processing of the coupling is often carried out by sleeves on the shaft. This is to make the tenon on the end face of the coupling accurately concentric with the center line of the shaft. In this processing process, special attention should be paid to ensure that the end face of the coupling is connected to the shaft. The rotor shaft is vertical, and attention should be paid to whether the alignment of the centering tenon 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) 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 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.
(3) Gear-type stability inspection: It needs to be removed for inspection when the transmission noise increases or the product is overhauled.
(4) The most 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 must not be obvious when viewed visually. I feel that when using the instrument to check, it cannot be greater than the limit.
