(1) When removing the coupling shaft, do not hit the hammer directly to pad the copper stick, and the hub of the bearing shaft should not be used to not be damaged by the outer edge of the shaft, because it is easily broken here. The ideal way is to disassemble the coupling with a captive. For small and medium -sized water pumps, because it has a small profits, it is easy to take it down. There is a large surgery in a large pump and a shaft and shaft, so the couplet must be heated when disassembling. (2) When assembling the couplet, pay attention to the serial number of the key (for the couplet with two or more keys). If you use a bronze stick, you must pay attention to the hit. For example, when knocking on the ends of the shaft hole, it is easy to cause a shaft hole to shrink, so that the shaft cannot be worn; the straightness of the end of the wheel will easily destroy the straightness of the end surface. Spend. For a joints with a large profit volume, it should be heated and then installed.

(3) Sales, nuts, rings, and rubber pads must ensure that their respective specifications and sizes must be consistent, so as not to affect the dynamic balance of the coupling. Corresponding marks should be made on the sales holes and corresponding couplet sales holes to prevent mistakes.

(4) The cooperation between the coupling and the axis generally uses a transition coordination. There may be a small amount of agent and a small amount of gaps. For long wickers, a loose transition can be used. For a long time, due to rough surface processing, part of the survey will naturally generate after assembly. If the coordination of the coupling and the shaft is too loose, it should be replenished when it affects the concentricity of the holes and shafts. Putting numbness or copper leather on the axis is an appropriate measure, and cannot be used as an ideal method.
