On hub reducer casing 1.
3 center of planet carrier is equipped with the through-hole for installing tire axis, and five are uniformly arranged around the through-hole for installing row
The circular hole of spider gear shaft 7, sun gear 13 are mounted on the end of tire axis, and planetary gear 5 is sleeved on planet wheel spindle 7, the sum of planetary gear 5
Needle bearing 9 and spacer 8 are packed between the diameter of axle of planet wheel spindle 7；Gear ring 12 is mounted on the outside of planet carrier 3, five planetary gears 5
Tooth form respectively with the tooth form of gear ring 12 and sun gear 13 cooperate.
It is provided with the round rectangle of through-hole centered on the end face of planetary gear gasket 6, is expert at using the through-hole set that its center is arranged
On spider gear shaft 7, end face is bonded with planet carrier 3；The end face of sun gear gasket 4 is pentagon, the pentagon end face of sun gear gasket 4
It docks, is mounted in the plane contacted with planet carrier 3 with the right angle end face 15 of five planetary gear gaskets 6；
Four rectangular section oil ducts are respectively adopted in the planetary gear 5, two end faces, for planetary gear gasket and planetary gear it
Between lubrication, and for the impurity discharge in needle bearing；At tooth root among tooth form, using four uniformly distributed circular holes, it is used for
Lubricating oil flow, and for the impurity discharge in needle bearing.
The planetary gear gasket is cooperated using the gabarit of squarish with five arms of angle of sun gear gasket；Using center
Hole cooperates with planet wheel spindle；Using two planar structures without oil duct, process costs are reduced.
The beneficial effects of the utility model are:
Two end faces of planetary gear promote the greasy property between planetary gear gasket, benefit using the oil channel structure of perforation
Impurity discharge in needle bearing；At the intermediate tooth root of planetary gear, using circle hole shape oil duct, guarantee that lubricating oil flow is unimpeded,
Conducive to the impurity discharge in needle bearing；Planetary gear gasket saves processing cost without oil channel structure.
