Abstract (en)
[origin: EP3048303A1] Groove portions (53, 55) are provided in a sliding contact surface of a first side plate (5) as to be positioned radially inside a root diameter of a drive gear (1) and radially outside a through hole (5a) into which a first rotary shaft (11) of the drive gear (1) is inserted, so that the through hole (5a) and a clearance groove (51) are not communicated with each other. Moreover, grooves (54, 56) are provided radially inside a root diameter of a driven gear (2) on the first side plate and radially outside a through hole (5b) into which a second rotary shaft (12) of the driven gear (2) is inserted, so that the through hole (5b) and the clearance groove (51) are not communicated with each other. As a consequence, a gear fluid device is provided which is capable of effectively preventing wear of sliding contact surfaces while keeping the lubricated state of the bearing part with simple construction.
