Aiming at the problem of the connecting position fusion at expansion sleeve coupling ofthe transmission shaft of the bucket wheel type reclaimer in Ningxia Zhongning Electric Power Genera?tion Co.

Ltd.

makes analysis and calculation seriously

changes the expansion sleeve coupling intothe involute spline coupling. The result shows that the main cause of connecting position fusion at ex?pansion sleeve coupling of the transmission shaft is the bucket wheel type reclaimer working mode inoverload condition

after changing the transmission mode

the load capacity of transmission shaft of thebucket wheel type reclaimer augment

overhaul facility; achieving the expectant effect.
