SUMMERY OF THE UTILITY MODEL
To the above-mentioned problem that exists among the prior art, the utility model aims at providing a differential mechanism cross axle structure, the lubricated groove structure of optimal design cross axle makes to form "rectangle" lubricated groove between cross axle and the planetary gear, can guarantee lubricated unobstructed, can avoid again that impurities such as iron cuts are crowded between cross axle and planetary gear cooperation are vice, realizes the lubrication of cross axle and planetary gear cooperation pair.
The utility model discloses a following technical scheme realizes:
the utility model provides a differential mechanism cross axle structure, includes annular connecting block, footpath and lubrication groove, footpath evenly distributed is the cruciform structure around annular connecting block, be provided with the lubrication groove on the footpath, the lubrication groove is the rectangle structure along the radial tangent plane in footpath.
Further, the depth of the lubricating oil groove ranges from 3 mm to 5mm, and the length of the lubricating oil groove is larger than the axial size of the planetary gear, as shown in a and b in fig. 6.
Compared with the prior art, the utility model has the advantages as follows:
the utility model discloses a differential mechanism cross axle structure is through forming "rectangle" lubrication groove between cross axle and planetary gear cooperation are vice for planetary gear is rotatory in-process, and the impurity such as the iron that gets into this oil groove can stay in the oil groove and not crowded between cross axle and planetary gear cooperation are vice, and then avoids the cross axle and planetary gear cooperation to wear and tear unusually and sintering, and the oil groove is darker, and lubricating oil flows unobstructed, and is lubricated effectual.
