Abstract:
1. A rotary sprayer for a coating apparatus, comprising: a spraying body for a coating material, the spraying body configured to be mounted on a drive shaft of a drive motor for rotation with the drive shaft during a coating procedure, the spraying body including a detachable mounting device for coaxial connection of a connecting component of the spraying body to the drive shaft; wherein the detachable mounting device includes a first mechanism and a second mechanism, at least the first mechanism configured to selectively secure the spraying body to the drive shaft, the second mechanism configured to prevent a self-acting complete detachment of the mounting device from the drive shaft when the spraying body is decelerated and accelerated with the drive shaft such that the first mechanism would, in the absence of the second mechanism, allow an undesirable movement of the spraying body radially about an axis of rotation of the drive shaft, the second mechanism being inactivated when the spraying body is not being rotated with the drive shaft such that the mounting device may be unfastened from the drive shaft; wherein a limit stop construction is provided, which, after unfastening the first mechanism, the second mechanism provides a limit stop that limits accidental axial relative movement between the spraying body and the drive shaft, and forms a guide for the spraying body to prevent radial relative movements between the spraying body and the drive shaft.
