DEVICE FOR APPLICATION OF POLYMERIC COATINGS ON INNER CYLINDRICAL SURFACES Russian patent published in 2001 - IPC

FIELD: devices for application of polymeric coatings on inner cylindrical surfaces, applicable for restoration of mounting surfaces of antifriction bearings of the base members. SUBSTANCE: the device has a rotating body with an annular reservoir for polymer and outlet ducts, that rests on a bedplate through a cover screwed in it, and a trust bearing. Slotted heads tightened to the surface of the processed hole with the aid of torsion springs are installed in the upper part of the rotating body around the edges of the flange for movement. The uniformity of fit of all slotted heads to the worked surface is controlled by an adjusting washer installed with its spiral holes on the pins of the slotted heads. To feed polymer from the annular reservoir of the rotating body to the cavity of the slotted heads, the device is provided with pipe unions of the outlet channel and slotted heads, as well as with flexible PVC tubes. The body is set in motion by means of reciprocating motion of the drive screw, manually driven in the cover nut. EFFECT: enhanced capacity of the process of application and quality of the applied coating. 2 dwg
