BEARING PROVISION DIVIDED IN A HOUSING, ESPECIALLY SMOOTHING CRANKSHAFT BEARING FOR ALTERNATIVE PISTON ENGINES.

摘要

Bearing arrangement divided into a housing, especially plain crankshaft bearing for reciprocating piston engines, comprising - a bearing seat (4) and a bearing cover (5) based on materials of different hardness, where - the cover of bearing (5) arranged in a bracing way against the bearing seat (4) and formed of a ferrous material has sharp projections (6) with sharp edges that are formed protruding from its clamping surface (7) and that - during a first The mounting of the bearing cover (5) is pressurized by applying force on the opposite clamping surface (10) of the bearing seat (4) formed of a light metal, and where - grooves (8) are also provided. on the clamping surface (7) of the bearing cover (5), characterized in that - the bearing cover (5) is formed with projections (6) having a cutting edge or pyramid profile, - presenting the projections (6 ) an angle d e edge at ~ 50º-110º, - also, the cutting edge ¿H¿ on the clamping surface (7) of the bearing cover (5) is between 0, 25 and 1, 5 mm, - joining grooves (8) rounded with radii of R = 0, 15-0, 30 mm, made with the respective measure of the radius ¿R¿ on the clamping surface (7), to the edge edges (6¿, 6¿), and - the grooves (8) are used to receive the material from the bearing seat (4) dislodged during the pressurization of the projections (6) into the bearing seat (4).
