Abstract
The utility model discloses a long-life differential mechanism cross mainly includes cross, axle journal, helicla flute, all is equipped with the helicla flute on four axle journals of cross, and the helicla flute distributes along axle journal axial spiral, and axle journal suit conical gear packs lubricating oil in the helicla flute. The spiral groove penetrates through the circumference of the shaft diameter to two ends. The utility model discloses equipartition helicla flute makes the lubricating oil equipartition on the cross axle journal, has reached better lubricated effect, has improved the noise and the wearing and tearing condition, has improved the life of differential mechanism cross axle, has solved the problem of differential mechanism cross axle because the poor noise that leads to of lubrication and early inefficacy in the use.
Description
Technical Field
The utility model relates to a differential mechanism's field, concretely relates to long-life differential mechanism cross axle.
Background
In the prior art, the differential spider is provided with notches on four shaft diameters, and the notches are machined by adopting a numerical control lathe in a rotating mode. When the differential operates, the bevel gear rotates at high speed, and lubricating oil flows to the surface of the shaft diameter through a gap on the differential spider, so that the purpose of lubricating the gear and the differential spider is achieved. According to the existing scheme for lubricating the notch on the differential spider, because the notch does not link up the whole shaft diameter, in the high-speed rotation process of the bevel gear, lubricating oil can only lubricate the shaft diameter through two sides of the notch on the differential spider, oil films are not uniformly distributed on the surface of the shaft diameter, the lubricating effect is poor, and the differential has noise and early wear in the operation process, so that the differential fails in advance.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a long-life differential mechanism cross.
The purpose of the utility model is accomplished through following technical scheme: the differential spider with the long service life mainly comprises a spider, shaft necks and spiral grooves, wherein the spiral grooves are formed in the four shaft necks of the spider, the spiral grooves are spirally distributed along the axial direction of the shaft necks, the shaft necks are sleeved with conical gears, and lubricating oil is filled in the spiral grooves.
The spiral groove penetrates through the circumference of the shaft diameter to two ends.
The utility model has the advantages that: the utility model discloses equipartition helicla flute makes the lubricating oil equipartition on the cross axle journal, has reached better lubricated effect, has improved the noise and the wearing and tearing condition, has improved the life of differential mechanism cross axle, has solved the problem of differential mechanism cross axle because the poor noise that leads to of lubrication and early inefficacy in the use.

Fig. 3 is a schematic structural diagram of the present invention.
Fig. 4 is a sectional view taken at B-B in fig. 3.
Description of reference numerals: a cross shaft 1, a shaft neck 2 and a spiral groove 3.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in the attached drawings, the differential spider with the long service life mainly comprises a spider 1, shaft necks 2 and spiral grooves 3, wherein the spiral grooves 3 are formed in the four shaft necks 2 of the spider 1, the spiral grooves 3 are spirally distributed along the axial direction of the shaft necks 2, the shaft necks 2 are sleeved with conical gears, and lubricating oil is filled in the spiral grooves 3. When the bevel gear runs, lubricating oil is uniformly distributed on the surface of the shaft diameter 2 through the spiral grooves 3 on the differential spider, so that the lubricating effect is improved, and the service life of the differential spider is prolonged. The spiral groove 3 penetrates through the circumference of the shaft diameter 2 to two ends, and the whole shaft diameter 2 can be effectively lubricated.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
Claims (2)
