Abstract

Keksinnön kohteena on esimerkiksi harvesteripään (1) ketjusahan (3) kärkipyörä (21), joka on kiinnitettävissä ketjusahan laippaan (11) sen suhteen ja sen tason sunnassa pyörivästi ketjusahan teräketjun (12) liikkeen tukemiseksi. Ainakin yhteen kärkipyörän pintaan (31) on muodostettu ainakin yksi kärkipyörän ulkoreunalta (27) tai ulkoreunan läheisyydestä kohti kärkipyörän keskiosaa (32) johtava voitelu-ura (33, 34) voiteluaineen johtamiseksi ulkoreunan ja keskiosan välillä. Lisäksi keksinnön kohteena on ketjusahan laippa (11), harvesteri (1) sekä menetelmä harvesteripään (2) ketjusahan (3) teräketjun (12) ja kärkipyörän (21 ) voitelemiseksi.The object of the invention is, for example, the tip wheel (21) of the chainsaw (3) of the harvester head (1), which can be attached to the flange (11) of the chainsaw in relation to it and its plane so as to rotate in order to support the movement of the chainsaw blade chain (12). At least one lubrication groove (33, 34) leading from the outer edge (27) of the outer edge (27) or the vicinity of the outer edge towards the central part (32) of the apex wheel is formed on at least one surface (31) to conduct the lubricant between the outer edge and the central part. In addition, the subject of the invention is a chainsaw flange (11), a harvester (1) and a method for lubricating the chainsaw (3), blade chain (12) and top wheel (21) of the harvester head (2).
