CRANKSHAFT BEARING CAP WITH OPTIMISED SUPPORTS Russian patent published in 2016 - IPC F16C9/02 F16C35/00 F02F7/00 

FIELD: machine building.

SUBSTANCE: invention relates to and crankshaft bearing caps, in particular, to attachment of these bearing caps. Cap (10) of crankshaft bearing of internal combustion engine has a shape of semicylinder (13) with its axis aligned with crankshaft axis and comprises diametrically opposite attachment supports (20). Each support (20) is made in the form of a post resting on the heel (26), and has essentially oval top surface (18), which includes a support surface (16), surrounding the hole (15) for passage of a fastening screw and bearing surface for screw head, the said surface surrounding passage opening (15). Attachment Support (20) comprises at least two vertical slot on its outer side surface extending from the base support on heel (26) and continued in the section support height. Slots are arranged outside of vertical support cylinder, its base equal to the support surface (16), and outside the volume confined by crosswise plane passing through the axis of the fastening holes and located symmetrically relative to direction along the length.

EFFECT: optimised shape of bearing cap supports.
