In the selection of bell jar couplings, it is often encountered that the oil pump shaft is a spline, commonly SAE and DIN5480 standard spline shafts. The spline holes of the coupling are usually machined by wire cutting. It should be noted that the half coupling that processes the spline needs to be checked for dynamic balance, otherwise abnormal shaking of the oil pump may occur during on-site installation
