Abstract
The utility model discloses a planetary gear of high lubricating property processes a plurality of arc walls as leading the oil groove at planetary gear's terminal surface. The arc-shaped grooves are divided into three parts, namely a first arc-shaped groove, a second arc-shaped groove and a third arc-shaped groove. The utility model provides a novel planetary gear's structure. The oil guide groove is processed on the end face of the planet gear, so that the planet gear has sufficient grease supplement in the running process, the planet gear assembly is kept to work in a high-lubrication state all the time, the running is smooth, and the noise is stable.
Description
Technical Field
The utility model relates to a planetary gear of high lubricating property belongs to planetary reducer technical field.
Background
At present, a planetary gear transmission assembly of a planetary reducer is lubricated by filling lubricating grease during assembly. Although the planetary gear assembly can be lubricated, insufficient lubrication occurs in a high-speed operation state and a long-time operation state, and thus, a problem such as wear of parts and noise occurs.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects, the utility model discloses the purpose is overcome lubricated not enough defect of present planet wheel transmission assembly when a small amount of incremental cost, provides a neotype planetary gear's structure. The oil guide groove is processed on the end face of the planet gear, so that the planet gear has sufficient grease supplement in the running process, the planet gear assembly is kept to work in a high-lubrication state all the time, the running is smooth, and the noise is stable.
The technical scheme of the utility model as follows:
a planetary gear with high lubricating performance is characterized in that a plurality of arc-shaped grooves are processed on the end face of the planetary gear to serve as oil guide grooves.
The arc-shaped grooves are divided into three parts, namely a first arc-shaped groove, a second arc-shaped groove and a third arc-shaped groove.
The first arc-shaped groove, the second arc-shaped groove and the third arc-shaped groove are discontinuous arcs and are separated by the planetary gear cavity, so that the planetary gear cavity is provided with 6 notches to be connected with the outside.
The circle centers of circles where the first arc-shaped groove, the second arc-shaped groove and the third arc-shaped groove are located are the same circle center.
The circle center is positioned at the top of the planet gear.
The utility model discloses the beneficial effect who reaches:
1. the planetary wheel assembly is kept to work in a high-lubrication state all the time;
2. continuous lubrication of the planetary gear assembly is realized;
3. under the same use condition of the speed reducer, the use performance of the product is improved, and the service life of the product is prolonged.
Drawings
FIG. 1 is a schematic structural diagram of the first embodiment;
fig. 2 is a structure of a single planet wheel in the first embodiment.
Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Example one
As shown in FIG. 2, in a planetary gear 1 with high lubricating performance, three arc-shaped grooves are processed on the end surface of the planetary gear 1, namely a first arc-shaped groove 1-1, a second arc-shaped groove 1-2 and a third arc-shaped groove 1-3.
The first arc-shaped groove 1-1, the second arc-shaped groove 1-2 and the third arc-shaped groove 1-3 are discontinuous arcs, and the middle of the arc is separated by the planetary gear cavity 2, so that the planetary gear cavity 2 is provided with 6 notches to be connected with the outside.
The circle centers of the circles of the first arc-shaped groove 1-1, the second arc-shaped groove 1-2 and the third arc-shaped groove 1-3 are the same circle center.
The circle center is positioned at the top of the planet gear.
As shown in fig. 1, when the speed reducer operates, the planetary gear 1 revolves around the sun gear 3, and meanwhile, in the process of rotation of the planetary gear 1, lubricating grease in the cavity 4 is brought into the planetary gear cavity 2 of the planetary gear assembly, and sufficient grease is supplemented into the planetary gear cavity 2 in the process of operation of the planetary gear, so that the planetary gear assembly is kept to operate in a high-lubrication state all the time, the operation is smooth, and the noise is stable. Continuous lubrication of the planetary gear assembly is achieved. Under the same use condition of the speed reducer, the use performance of the product is improved, and the service life of the product is prolonged.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
