In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not constitute limitations on the invention.
The transmission bearing lubricating device provided by the embodiment of the invention will be described in detail below.
Fig. 1 shows a schematic structural view of a transmission bearing lubrication device of the present invention; fig. 2 shows a cavity internal view of the transmission bearing lubricating device of the present invention.
As shown in fig. 1, for the sake of convenience of the following description, a side close to the edge of the transmission case 1 is referred to as an outer side, and a side away from the edge of the transmission case 1 and close to the middle region of the transmission is referred to as an inner side. The utility model discloses a derailleur bearing lubricating arrangement lubricates for inboard bearing 4 and outside bearing 7 in the derailleur.
The utility model discloses a transmission bearing lubricating device, which comprises a gear circumferential rib 2 for limiting the throwing-out direction of lubricating oil, a cavity positioned in the throwing-out direction of the lubricating oil, and an oil blocking rib 3 for blocking a part of the thrown-out lubricating oil; for the convenience of the following description, the direction of gravity, i.e., the vertically downward direction, is referred to as downward, and the opposite direction to the direction of gravity is referred to as upward. The inner bearing 4 and the outer bearing 7 are positioned below the cavity in space, but not directly below, so that the inner bearing 4 and the outer bearing 7 are lubricated by the flow of the lubricating oil itself by gravity. The cavity is connected with the inner side bearing 4 through the oil blocking rib 3, the oil blocking rib 3 can block a part of thrown lubricating oil, and meanwhile, a part of lubricating oil received by the cavity is reserved to the oil blocking rib 3 and flows to the inner side bearing 4 along the oil blocking rib 3. The cavity is connected with the outer bearing 7 through the oil guide groove 6, and the outer bearing 7 is lubricated through the drainage of the oil guide groove 6.
The utility model discloses an in an embodiment, after adding lubricating oil, the softening oil is thrown away through the gear rotation on the derailleur, and gear circumference muscle 2 is fixed in the direction that people's lubricating oil was thrown away, and lubricating oil can be along the surface motion of gear circumference muscle 2, and the extending direction of gear circumference muscle 2 has injectd the direction of throwing away of lubricating oil, ensures that lubricating oil is thrown away along same direction.
In one embodiment of the present invention, the extending direction of the gear circumferential rib 2 is substantially horizontal, so that the lubricating oil is thrown out in parallel. Preferably, the gear circumferential rib 2 is provided with a tail end which is tilted upwards, so that the gear circumferential rib moves along a parabola, the movement track of lubricating oil is increased, and the cavity and the oil blocking rib 3 can be conveniently connected. The thrown lubricating oil is divided into two parts due to inertia and gravity, one part flows to the oil guide groove 6 through the cavity, and the other part is blocked by the oil blocking rib 3 which is obliquely arranged downwards and is connected with the cavity and the inner side bearing 4 and flows to the inner side bearing 4.
In one embodiment of the present invention, the cavity is composed of the oil baffle 5 and the housing 1.
