Abstract

Keksintö koskee hihnatelaa kuiturainakonetta varten. Hihnatelaan (10) kuuluu pyörimätön paineakseli (11), johon kuuluu kuormitusalue (39). Lisäksi hihnatelaan (10) kuuluu kuormitussylintereitä (17) tuettuna paineakselille (11) kuormitusalueella (39). Edelleen hihnatelaan (10) kuuluu kuormitussylintereihin (17) yhdistetty ja paineakselin (11) suhteen liikkumaan sovitettu painekenkä (12), joka ulottuu oleellisesti kuormitusalueen (39) pituudelle. Hihnatelaan (10) kuuluu myös kuormitusöljylinja (18) paineistetun öljyn syöttämiseksi kuormitussylintereille (17) painekengän (12) kuormittamiseksi. Osana kuormitusöljylinjaa (18) painekenkään (12) kuuluu kanava (19), joka ulottuu kuormitussylinterien (17) kohdalle ja kanavasta (19) on yhde (20) usealle kuormitussylinterille (17).The invention relates to a belt roll for a fibrous web machine. The belt roller (10) comprises a non-rotating pressure shaft (11) which includes a load area (39). In addition, the belt roller (10) comprises load cylinders (17) supported on the pressure shaft (11) in the load area (39). Furthermore, the belt roller (10) comprises a pressure shoe (12) connected to the load cylinders (17) and adapted to move relative to the pressure shaft (11), which extends substantially the length of the load area (39). The belt roller (10) also includes a load oil line (18) for supplying pressurized oil to the load cylinders (17) to load the pressure shoe (12). As part of the load oil line (18), the pressure shoe (12) includes a passage (19) extending at the load cylinders (17) and the passage (19) being one (20) for a plurality of load cylinders (17).
