The coaxiality of the coupling is the extension of the axis of the connected equipment in a straight line called coaxial.
Coaxiality of mechanical and electrical equipment couplings is an important item for the quality requirements of mechanical and electrical equipment installation and maintenance.The coaxiality directly affects the operation of the connected equipment.Equipment with good coaxiality runs smoothly, with low noise, long service life, and high efficiency; if the coaxiality deviation is too large, the probability of serious consequences is greater.
However, it is difficult to achieve coaxiality in the installation and use of equipment, and some deviations will inevitably occur.Therefore, according to this situation, some deviation ranges that allow the axis of the connected equipment to not be on a straight line have been formulated. This deviation range is called coaxiality.
Since deviations are allowed, the extension of the axis of the connected equipment may appear in the following three situations: ①The two axes are displaced in parallel; ②The extension of the two axes intersect; ③The two exist at the same time.The deviations of these axes are encountered on the coupling, which is called the radial displacement and end face tilt of the coupling.The two are collectively called the coaxiality of the coupling.
