Problems solved by technology

[0003] At present, this kind of gear lubrication method that uses external oil lubrication, once the lubrication system fails or the oil in the lubrication system is insufficient or due to other reasons, some gears in the gear train are not sufficiently lubricated, which will cause great damage to the poorly lubricated gears. The damage of the gear reduces the service life of the gear; and the lubricating medium cannot enter the friction interface due to the high temperature, high pressure and high sliding speed between the tooth surfaces of the conventional tooth surface friction interface, and the lubricating medium at the interface is often difficult to form a continuous lubricating film

Abstract

The invention discloses a self-lubricating gear with a micro-texture. The micro-texture includes a transverse groove array arranged on the meshing tooth surface of the gear. The transverse groove array includes transverse grooves arranged in parallel, and the transverse groove The depth direction of the groove is perpendicular to the meshing tooth surface, and the lubricating medium is also filled in the transverse groove, and the micro-texture also includes an outer groove with a closed edge provided on the periphery of the transverse groove array on the meshing tooth surface, and The edge of the outer groove perpendicular to the friction direction of the meshing tooth surface is an arc edge, and the bottom surface of the outer groove is a slope inclined to the transverse groove. The invention uses a special micro-texture to fill the lubricating medium and then softens to form a lubricating film under the high temperature generated by friction, so as to realize the continuous lubricating effect in the friction area of ​​the tooth surface, and has the advantages of saving lubricating medium, long service life and good lubricating effect. It can suppress tooth surface wear and avoid damage to gears that may be caused by external oil lubrication or other lubrication methods.

Description

technical field [0001] The invention belongs to the technical field of gear manufacturing, in particular to a self-lubricating gear with micro-texture. Background technique [0002] Gears are common mechanical components in people's lives, and they are widely used in mechanical transmission mechanisms to transmit motion and power. The gears are transmitted through mutual meshing, and the sliding friction between the tooth surfaces is mainly accompanied by rolling friction. Therefore, the rotation of the gears is inseparable from lubrication. If there is not enough lubrication, it will cause great damage to the gears and reduce the service life of the gears. At present, the lubrication method of gears mostly adopts the method of external oil lubrication, adding lubricating oil to the surface of the gear to lubricate the gear, such as: drip lubrication (drop lubricating oil to the friction surface of the moving pair), splash lubrication (lubricate the lubricant Splash to the ...
