GAS-THERMAL METHOD OF SPRAY COATING ROTATION BODY AND DEVICE FOR IMPLEMENTING METHOD Russian patent published in 2008 - IPC B05D1/08 B05B7/20 

FIELD: spray coating techniques.

SUBSTANCE: method involves displacement of a sprayer along a rotation body and turning the sprayer in the plane of displacement such that, the longitudinal axis of the sprayer is perpendicular to the rotation body. Turning the sprayer is done about an axis, passing through the centre of the sprayed spherical surface. In the device for gas-thermal spray coating a rotation body, the mechanism of out-in traverse of the sprayer is made in form of two levers, joined to each other by a bar. The end of one of the levers is fixed to the case of a holder frame, and the end of the other is fixed to the axis of a hinge. The mechanism of azimuthal displacement of the sprayer is made in form of a beam with a triangular groove and hinged to a disc, on which there are supports, limiting movement of the beam. The mechanism for moving the sprayer along its longitudinal axis is made in form of plates, one end of which is joined to the sprayer, and the other end is made with bending and encircles the beam. The plate itself is fixed on the beam using a screw, moving along the triangular groove of the beam. Besides that, the axis of the hinge passes through the axis of rotation of a spindle and the centre of a spherical surface. The simple structure of the proposed device allows for simplifying its production and easier control. The proposed device is simple and convenient for operation.

EFFECT: increased uniformity of spray coating when reconstructing objects with a spherical surface; lowering of power consumption of the process; simplification of the structure of the coating device and easier of control.
