The third deflector hole in hole and third step surface.
By using above-mentioned technical proposal, adaptation is respectively mounted on First terrace, second step face and third step surface
Lubricating oil can be filled in blind hole for rotatable parts, and the internal thread on blind hole open end plays envelope for connecting sealing screw to blind hole
Stifled effect, lubricating oil can with the first deflector hole, the second deflector hole and third deflector hole seepage flow to corresponding First terrace,
On second step face and third step surface, increase First terrace, second step face and third step surface lubrication, reduce friction
And abrasion, extend axis body service life, mounting hole is used for fixing bolt and gasket, prevents rotatable parts along axis body axis by gasket
To slippage.
The utility model is further arranged to：The mounting hole include the first pilot hole being axially sequentially communicated along axis body,
Second pilot hole, cushion hole, third pilot hole and threaded hole, the first pilot hole are placed on the end face of axis body, the first pilot hole
Hole wall is tapered and is connect with axis body end face, and the hole wall of the second pilot hole and third pilot hole is also tapered, the hole of cushion hole
Wall is connect with the hole wall of third pilot hole by arc reinforced wall.
By using above-mentioned technical proposal, the hole wall of the first pilot hole and the second pilot hole is taper, convenient for bolt
Installation, in use, the gasket for playing fixed function can be by axial force, to act power, the first pilot hole to axis body end face
Stress intensity, the tension that third pilot hole is used to that bolt to be avoided to rotate can be improved with the hole wall structure of the second pilot hole, and is made
At sliding tooth, arc reinforced wall can increase the forced area between cushion hole and third pilot hole, disperse surface stress, improve knot
Structure intensity.
The utility model is further arranged to：The First terrace is equipped with location hole.
By using above-mentioned technical proposal, location hole is used for the connection with external component and positions, and limitation circumferentially rotates.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of driven axle embodiment of the utility model.
Specific implementation mode
A kind of driven axle embodiment of the utility model is described further referring to Fig.1.
