Description

455 222 Åstadkommandet av ett par dylika urtag 26, 27 sker lämpligen vid presstill- verkningen av vevstaken. Urtagens storlek fâr begränsas med hänsyn till beräknad pàkänning på lagret vid kolvens övre vändpunkt. Under huvuddelen av kolvens rörelse utsättas dock kolvtappslagrets undre halva för den största pakänningen, varför urtagen i den övre halvan inte påverkar lagrets totala halifasthet negativt. 455 222 The production of a pair of such recesses 26, 27 suitably takes place in the press production of the connecting rod. The size of the recesses may be limited with regard to the calculated stress on the bearing at the upper turning point of the piston. During the main part of the piston's movement, however, the lower half of the piston pin bearing is exposed to the largest packing stress, so that the recesses in the upper half do not adversely affect the total halifast of the bearing.

Claims (2)

1. 455 222 Patentkrav l. Anordning i förbränningsmotor med minst en kolv (10) i en cylinder och en vevstake (11) lagrad medelst kolvuappslager(l7) vid kolven och vevstaks- lager (16) till en vevaxel (12), varav kolvtappslagret har axiella lagringsytor (24. 25) på vevstaken respektive kolven, vilka ytor på vevstaken är belägna i en undre lagerhalva, medan segmenturtag (26, 27) är utförda i den övre halvan av lagret, k ä n n e t e c k n a d d ä r a v , att lagringsytorna på kolven har l sin helhet plan utformning och uttagen, som är placerade i vevstaken, därigenom bildar en öppen väg för smörjmedel till kolvtappen (18) i kolvtappslagret. .A device in an internal combustion engine with at least one piston (10) in a cylinder and a connecting rod (11) mounted by means of piston bearings (17) at the piston and connecting rod bearings (16) to a crankshaft (12), of which the piston pin bearing have axial bearing surfaces (24. 25) on the connecting rod and the piston, respectively, which surfaces on the connecting rod are located in a lower bearing half, while segment recesses (26, 27) are made in the upper half of the bearing, characterized in that the bearing surfaces on the piston has in its entirety a flat design and the sockets, which are located in the connecting rod, thereby forming an open path for lubricant to the piston pin (18) in the piston pin bearing. . 2. Anordning enligt patentkravet l, k ä n n e t e c k n a d d ä r a v, att vardera urraget är begränsat av ett snedplan utsträckt från en skiljelinje mellan nämnda övre och undre lagerhalvor, vinkelrätt mot lagertappen. varvid planet bildar en vinkel v > 0 mot motsvarande lagrlngsyta på kolven.Device according to claim 1, characterized in that each recess is delimited by an inclined plane extending from a dividing line between said upper and lower bearing halves, perpendicular to the bearing pin. wherein the plane forms an angle v> 0 towards the corresponding bearing surface on the piston.
