Axial offset The axial distance that the coupling is allowed to move when connecting two shafts.The allowable offset angle when the angular offset coupler connects two shafts.High-precision couplings should be manufactured in accordance with the requirements of the standard and the drawings and technical documents approved by the prescribed procedures.The surface roughness Ra value of the shaft hole and shaft of the high-precision coupling is not more than 0.8um, the surface roughness Ra value of the shaft sleeve end surface is not more than 1.6um, and the surface roughness Ra value of the remaining parts is not more than 3.2um.The transmission error of the high-precision coupling is not more than 1; the idle travel error is not more than 1; the accuracy level of the shafting accuracy of the connected transmission components should be greater than 6.Coaxiality and axial, radial and angular offset.

　　For coupling diaphragms with an outer diameter greater than 300, connecting rod coupling diaphragms are generally used, because standard 304 stainless steel plates are 1 meter * 2 meters, and coupling diaphragms with large outer diameters do not have standard plates. , Can use scraps to cut into the same size for anchoring and pressing, the use effect is greater than the integral coupling diaphragm.
