Abstract:

An apparatus for applying a hardenable or curable liquid coating, such as "varnish" to workpieces, such as electric motor rotor or stator conductor windings comprises a rotary table having plural workpiece supports mounted on the table circumferentially spaced and radially outwardly projecting. Rotatable stator grippers or rotor support heads are mounted at each support and are drivenly engaged with a drive mechanism, including a drive shaft assembly which is operably connected to a ring gear disposed centrally on the table and coaxial with the axis of rotation of the table. The ring gear is drivenly connected to a variable speed drive motor. Electric alternator stator members may be mounted at each support by a releasable pneumatically actuated gripper assembly which is mounted for rotation by a retractable friction wheel connected to the drive shaft assembly. Retractable induction heaters are disposed adjacent to the table for movement between working and non-working positions to heat workpieces prior to application of the liquid coating at a coating applicator station. A pressure fluid rotary coupling unit is operable to distribute pressure fluid to each workpiece support.
