INSTALLATION FOR THE PLASMA SPRAYING ON THE CRANKSHAFTS Russian patent published in 2007 - IPC C23C4/00 B05B5/14 

FIELD: mechanical engineering; production of installations of the plasma spraying on the crankshafts.

SUBSTANCE: the invention is pertaining to the installation of the plasma spraying on the crankshafts and may find application in the mechanical engineering. The installation has the heat-sound-insulation chamber, which consists of the shot-blasting section and the spraying section separated by the septum. The gear of transportation of the details consists of: the stationary guides, the movable guide with the bracket, the plate for mounting of the motor-reducer, the pneumatic cylinder for transportation of the detail into the spraying section and the pneumatic cylinders for transportation of the details into the shot-blasting section. The stationary guides are placed on the cover of the heat-sound-insulation chamber perpendicularly to the detail rotation axis. The movable guide is connected to the stationary guides and on it there is the motor-reducer mounting plate linked with the pneumatic cylinder rod used for transportation of the detail into the spraying section. This rod is rigidly fixed on the movable guide bracket. The indicated movable guide is rigidly connected with the rods of the pneumatic cylinders for transportation of the detail into the shot-blasting section. The rods are rigidly fixed on the cover of the heat-sound-insulation chamber. Such design of the installation allows to increase the adhesion strength of the produced coating due to reduction of the time between the shot-blasting treatment and the spraying and also to decrease the labor input used for the detail mounting at the centers.

EFFECT: the invention ensures the increased adhesion strength of the produced coating, reduction of the time between the shot-blasting treatment and the spraying operations, the decreased labor input used for the detail mounting at the centers.
