DEVICE FOR SPATIAL EXPOSURE OF SPHERICAL PIECES HAVING MAXIMAL DIMENSIONS, SUBJECTED TO TITANIUM ION EMISSION IN LOW-PRESSURE CHAMBER OF TITANIUM-COATING PLANT

摘要

The invention relates to a device for the spatial exposure of pieces having spherical shape and maximally increased dimensions, which are subjected to titanium ion emission in a low-pressure chamber of a titanium-coating plant, the device exhibiting a unitary and modulated structure which is yielding and resilient, being interchangeable and adaptable to any titanizing plant at minimal costs, with application in the machine building industry. According to the invention, the device consists of a clockwise rotating plate (1) on which six small-sized anti-clockwise rotating trays (2) are arranged, an inclined plate (5) provided with one or several cells meant to provide stability to the spherical pieces (4), a rotating plate (6) of rough surface on which the spherical piece (4) runs , where the inclined plate (5) has a central casing in which there is the radial bearing (17) wherethrough the central shaft of the rotating plate (6) passes, actuated by a gearing consisting of a toothed crown (7) and a driving wheel (8) which is driven by the tray (2), by means of a cardan shaft (9), centrally mounted with flanges on the tray axis and two fixed abutment members (10 and 11), i.e. an upper one and a lower one, meant to maintain the inclined position of the plate (5), both members (10 and 11) removing the load of the rotating plate (6) by means of the supports (12).
