摘要： The gasket assembly comprises an annular gasket (20) and a coaxial thrust ring. The central portion of the ring (20) is bounded by two faces (35) and (36) which are parallel and inclined so that the thickness of the central portion remains constant. The face (35) meets a face (34) by way of a portion (37) forming a right angle therewith, and the face (36) meets a face (32) by way of a portion (38) forming a right angle therewith. The contacting surface between the ring (30) and annular cavity (8) and between the gasket (20) and annular cavity (8) do not vary substantially as the degree of compression of the assembly varies; moreover, the deformation to which the ring (300 is subjected is substantially one of flexure. This means that as the degree of compression varies, in proximity to the working position, the axial thrust transmitted by the ring (30)tothe annular gasket (28) does not vary substantially.

摘要： In the improved roller, sealing means (9) at either end each comprise a metal annular element (11) which is able to shift axially, and incorporates a smooth, slender frontal rim (14) breasted with the outward-facing frontal surface of the outer race (5) of an adjacent bearing (4) ; and a thrust washer (15) lodged between a relative thrust-bracket (7) and metal annular element (11). The surfaces actually breasted in relative rotation are those of the smooth rim (14) and the bearing outer race (5). The disclosed roller seeks to improve on existing types by simplifying and cutting the cost of manufacture, and at the same time, enhancing performance.

摘要： The invention refers to a process for the production of track bushes for tractors and tracked vehicles in general, said bushes being carburized in semicontinuous furnaces, with preheating chamber and extraction chamber, in which the carburizing atmosphere is obtained directly in situ, and then individually submitted to direct quenching, followed by tempering of the ends and total stress-relieving.
The production cycle calls for tight control of temperatures and of treatment times as well as of the composition of the carburizing atmosphere; on the other hand it ensures a big saving in energy, shorter treatment times and consistently high product quality.
