Abstract

A rotary sprayer for a coating apparatus is disclosed. An exemplary rotary sprayer may include a spraying body configured to be mounted on a drive shaft of a drive motor for rotation with the drive shaft. The spraying body may further include a detachable mounting device for coaxial connection of the spraying body to the drive shaft. The detachable mounting device may include a spraying body thread that mates with a driveshaft thread defined by the drive shaft, and a plurality of elastic tabs configured to abut a corresponding cavity defined by the driveshaft, such that rotation of the spraying body increases an abutment force between the elastic tabs and the corresponding cavity of the driveshaft.
