Abstract
The utility model relates to a planetary row lubricating device for a planetary gear-box. The utility model is characterized in that at least two radial communicating holes are arranged on a planetary gear, so lubricating holes on planetary axis are replaced by the communicating holes on the planetary gear for lubricating needle rollers. Since at least two lubricating roles are arranged face to face in radial direction between gear teeth on the planetary gear, pressure difference exists between two lubricating holes, one hole for oil out, the other hole for oil in, so that lubricating oil circulation of planetary row needle rollers of the planetary gear-box is formed and the lubrication on planetary row needle rollers of the planetary gear-box is also improved. The utility model can guarantee the bending strength of the planetary axis and make drilling operation more easy and convenient.
Description
Technical field
The utility model relates to a kind of planetary driving mechanism that is used for, and is specially adapted to the planetary transmission planet row lubricating fitting on the engineering machinery such as loader.
Background technique
In present planetary transmission, be to adopt the mode of on planet axis, boring oilhole to make planet axis form the lubrication hole that connects, with lubrication quill always; Have plenty of and on planet axis, bore elongated inclined hole, directly lubrication quill.The deficiency of said structure is: bore relatively difficulty of elongated inclined hole on planet axis; Axially bore big center hole in planet axis, cumbersome to the little hole processing of brill at the planet diameter of axle again, particularly the resistance to flexure of planet axis is weakened, and especially in the cross section of the planet diameter of axle to the brill aperture, the resistance to flexure of planet axis is by very big weakening.
Summary of the invention
The purpose of this utility model just provides a kind of resistance to flexure that improves planet axis, the planetary transmission planet row lubricating fitting that makes boring processing become easy and easy.
Solution of the present utility model is such: have the through hole of at least two radial communication on planet wheel, thereby cancelled the oilhole on the planet axis, and by the through hole of opening on planet wheel needle roller is lubricated.
The utility model has the advantages that the resistance to flexure that guarantees planet axis, boring processing is become easily with easy.
Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is that the utility model through hole 8 is the structural representation of straight hole.
Accompanying drawing 2 is that the utility model through hole 8 is the structural representation of inclined hole.
Embodiment
The utility model includes planet wheel 1, planet axis 2, sun gear 3, pad 4, needle roller 5, planet carrier 6, gear ring 7.
On planet wheel 1, have the through hole 8 of at least two radial communication.In the present embodiment, described through hole 8 is to be distributed on the planet wheel 1; Described through hole 8 is straight holes.
During the utility model work, owing to radially be distributed with at least two lubrication holes relatively between the gear teeth on the planet wheel, between two oilholes pressure difference is arranged necessarily, such hole is fuel-displaced, another hole will oil-feed, one-in-and-one-out, thus the lubrication oil circulation that the planetary transmission planet is arranged needle roller formed, improved the lubricated of planetary transmission planet row needle roller better.
Described in actual use through hole 8 can be a straight hole, as shown in Figure 1; It also can be inclined hole.Through hole 8 can be to be distributed on the planet wheel 1, also can right and wrong are uniform opens on planet wheel 1.
Claims (4)
1, a kind of planetary transmission planet row lubricating fitting, include planet wheel (1), planet axis (2), sun gear (3), needle roller (5), planet carrier (6), gear ring (7), it is characterized in that on planet wheel (1), having the through hole (8) of at least two radial communication.
2, planetary transmission planet row lubricating fitting according to claim 1 is characterized in that described through hole (8) is to be distributed on the planet wheel (1).
3, planetary transmission planet row lubricating fitting according to claim 1 and 2 is characterized in that described through hole (8) is a straight hole.
