Abstract
Oil duct planet carrier, including axis body are carried the utility model discloses one kind, one end of axis body has to be connected between the sidepiece for being provided with and being parallel to each other on bearing mounting base, bearing mounting base, the sidepiece being parallel to each other through fishplate bar, and its key is：One end of the axis body is provided with sun wheel shaft mounting hole, main oil gallery is offered on the side wall of the axis body, auxiliary oil duct is further opened with along along the side wall of the bearing mounting base, described auxiliary oil duct one end is communicated with the main oil gallery, the auxiliary oil duct other end connection planetary gear installation cavity.Increase auxiliary oil duct on the wall of bearing mounting base side so that lubricating oil is quickly efficiently entering in planet gear transmission system, the lubricating system that planetary transmission system is effectively ensured normally is run.
Description
Technical field
The utility model is related to speed changer planet carrier technical field, specifically, is that one kind carries oil duct planet carrier.
Background technology
Planetary transmission system is a kind of gear train assembly with shaft line, available for slowing down, speedup and differential
Device.Planet carrier is a strength member in planetary transmission system, when planetary sun gear is used as a driving
During device, the lubricant effect of lubricating system is not good, and then increases the fretting wear between gear, reduces the service life of gear.
Utility model content
In view of this, the utility model provides one kind and carries oil duct planet carrier, by increasing on the wall of bearing mounting base side
Auxiliary oil duct, it is ensured that the lubricating system of planetary transmission system is normally run.Concrete technical scheme is as follows：
One kind carries oil duct planet carrier, including axis body, and one end of axis body has to be set on bearing mounting base, bearing mounting base
There is the sidepiece being parallel to each other, connected between the sidepiece being parallel to each other through fishplate bar, its key is：One end of the axis body is set
Have and offer main oil gallery on sun wheel shaft mounting hole, the side wall of the axis body, also opened up along along the side wall of the bearing mounting base
There is auxiliary oil duct, described auxiliary oil duct one end is communicated with the main oil gallery, the auxiliary oil duct other end connection planetary gear installation cavity.
Design based on said structure, increases auxiliary oil duct so that lubricating oil quickly effectively enters on the wall of bearing mounting base side
Enter into planet gear transmission system, the lubricating system that planetary transmission system is effectively ensured normally is run.
Further, planet axis installing hole is provided with the sidepiece being parallel to each other, planetary gear passes through installed in planet axis
Wheel shaft on mounting hole is arranged between two sidepieces being parallel to each other, and planetary gear is connected by gear engagement with the sun gear
Together.The planet axis installing hole is provided with 5, is distributed on what is be parallel to each other centered on the hole heart of sun wheel shaft mounting hole
On sidepiece.
Further, in order to fix the axis body, the other end of the axis body is provided with spline.
Beneficial effect：It is simple in construction, by increasing auxiliary oil duct on the wall of bearing mounting base side so that lubricating oil is quickly effective
Enter in planet gear transmission system, the lubricating system that planetary transmission system is effectively ensured normally is run.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model；
Fig. 2 is Fig. 1 left view.
Embodiment
With reference to embodiment and accompanying drawing, the utility model is described in further detail.
One kind as shown in Figure 1 to Figure 2 carries oil duct planet carrier, including axis body 1, and one end of axis body 1 has bearing installation
The sidepiece 3 being parallel to each other is provided with seat 2, bearing mounting base 2, is connected between the sidepiece 3 being parallel to each other through fishplate bar 4, it is closed
Key is：One end of the axis body 1 is provided with sun wheel shaft mounting hole 5, the side wall of the axis body 1 and offers main oil gallery 6, edge
Auxiliary oil duct 7 is further opened with the side wall of the bearing mounting base 2, described auxiliary one end of oil duct 7 is communicated with the main oil gallery 6, described
The auxiliary other end of oil duct 7 connection planetary gear installation cavity 8.
Design based on said structure, increases auxiliary oil duct 7 so that lubricating oil is quickly effective on the side wall of bearing mounting base 2
Enter in planet gear transmission system, the lubricating system that planetary transmission system is effectively ensured normally is run.
By Fig. 2 it is also seen that being provided with planet axis installing hole 9 on the sidepiece 3 being parallel to each other, planetary gear is by installing
Wheel shaft in planet axis installing hole 9 is arranged between two sidepieces 3 being parallel to each other, planetary gear by gear engage with it is described
Sun gear 6 links together.The planet axis installing hole 9 is provided with 5, centered on the hole heart of sun wheel shaft mounting hole 5
Cloth is on the sidepiece 3 being parallel to each other.
By Fig. 1 it is also seen that in order to fix the axis body 1, the other end of the axis body 1 is provided with spline 10.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modifications, equivalent substitutions and improvements made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
