GEAR FLUID DEVICE

Document Type and Number:

WIPO Patent Application WO/2015/040985

Kind Code:

A1

Abstract:

Groove parts (53, 55) are disposed on the sliding contact surface of a first side plate (5) more towards the inside in the radial direction than the root diameter of a drive gear (1) and more towards the outside in the radial direction than a through hole (5a), into which a first rotation shaft (11) of the drive gear (1) is inserted, so that the through hole (5a) does not communicate with a clearance groove (51). Moreover, grooves (54, 56) are disposed more towards the inside in the radial direction than the root diameter of a driven gear (2) on the first side plate and more towards the outside in the radial direction than a through hole (5b), into which a second rotation shaft (12) of the driven gear (2) is inserted, so that the through hole (5b) does not communicate with the clearance groove (51). As a consequence, a gear fluid device, which is capable of effectively preventing abrasions on the slide contact surface while maintaining the lubricated state of a bearing part by means of a simple configuration, is provided.
