Abstract
The invention discloses a kind of vittate planet carrier structures of band, and including axis body, one end of axis body has bearing mounting base, is provided with the side being mutually parallel on bearing mounting base, is connected between the side being mutually parallel through fishplate bar, 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 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 bearing mounting base side wall so that lubricating oil is quickly and effectively entered in planet gear transmission system, and the lubricating system normal operation of planetary transmission system is effectively ensured.
Description
Technical field
The present invention relates to speed changer planet carrier technical field, specifically, being a kind of vittate planet carrier structure of band.
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 an important part in planetary transmission system, when planetary sun gear is as a driving
During device, the lubricant effect of lubricating system is bad, and then increases the fretting wear between gear, reduces the service life of gear.
Invention content
In view of this, the present invention provides a kind of vittate planet carrier structure of band, by increasing on bearing mounting base side wall
Add auxiliary oil duct, ensure the lubricating system normal operation of planetary transmission system.Specific technical solution is as follows：
A kind of vittate planet carrier structure of band, including axis body, one end of axis body has bearing mounting base, is set on bearing mounting base
The side being mutually parallel is equipped with, is connected between the side being mutually parallel through fishplate bar, key is：One end of the axis body is set
Sun wheel shaft mounting hole is equipped with, main oil gallery is offered on the side wall of the axis body, is also opened along the side wall of the bearing mounting base
Equipped with 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 above structure increases auxiliary oil duct on bearing mounting base side wall so that lubricating oil quickly and effectively into
Enter into planet gear transmission system, the lubricating system normal operation of planetary transmission system is effectively ensured.
Further, planet axis installing hole is provided on the side being mutually parallel, planetary gear is by being mounted on planet axis
Wheel shaft on mounting hole is mounted between two sides being mutually parallel, and planetary gear is engaged by gear and connect with the sun gear
Together.The planet axis installing hole is provided with 5, is distributed on what is be mutually parallel centered on the hole heart of sun wheel shaft mounting hole
On side.
Further, in order to fix the axis body, the other end of the axis body is provided with spline.
Advantageous effect：It is simple in structure, by increasing auxiliary oil duct on bearing mounting base side wall so that lubricating oil is fast and effective
It enters in planet gear transmission system, the lubricating system normal operation of planetary transmission system is effectively ensured.
Description of the drawings
Fig. 1 is the structure chart of the present invention；
Fig. 2 is the left view of Fig. 1.
Specific embodiment
With reference to embodiment and attached drawing, the invention will be further described.
The vittate planet carrier structure of a kind of band as shown in Figure 1 to Figure 2, including axis body 1, one end of axis body 1 has axis
Mounting base 2 is held, the side 3 being mutually parallel is provided on bearing mounting base 2, is connected between the side being mutually parallel 3 through fishplate bar 4
It connects, key is：One end of the axis body 1 is provided with sun wheel shaft mounting hole 5, and master is offered on the side wall of the axis body 1
Oil duct 6 is further opened with auxiliary oil duct 7, described auxiliary 7 one end of oil duct and 6 phase of main oil gallery along the side wall of the bearing mounting base 2
It is logical, auxiliary 7 other end of the oil duct connection planetary gear installation cavity 8.
Design based on above structure increases auxiliary oil duct 7 so that lubricating oil is fast and effective on 2 side wall of bearing mounting base
It enters in planet gear transmission system, the lubricating system normal operation of planetary transmission system is effectively ensured.
By Fig. 2 it is also seen that being provided with planet axis installing hole 9 on the side 3 being mutually parallel, planetary gear passes through installation
Wheel shaft in planet axis installing hole 9 is mounted between two sides 3 being mutually parallel, 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 side 3 being mutually parallel.
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.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.
