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.
