| 20090165588 | GEAR ROTATION TRANSMISSION DEVICE - Since lubricating oil is injected to a tooth of a small-diameter helical gear immediately before meshing begins, the injected lubricating oil can be captured between the small-diameter helical gear and a large-diameter helical gear and successively flow along meshing tooth surfaces. Therefore, lubrication of the tooth surface and cooling of the tooth surface can be simultaneously performed with an appropriate quantity of lubricating oil to enable a reduction in tooth surface wear and a longer gear life. Moreover, a lubricating oil film formed on the tooth surface makes it possible to prevent direct contact between the tooth surfaces of both the small-diameter helical gear and the large-diameter helical gear. Since a covered tooth surface effect is also obtained, the occurrence of pitching and scoring can be suppressed. By injecting lubricating oil directly to the small-diameter helical gear, which has a small heat capacity, a cooling effect thus obtained can suppress a temperature increase of the small gear. Moreover, the occurrence of tooth damage such as pitching and scoring caused by a temperature increase can also be greatly suppressed. | 07-02-2009 |
