Skeleton rubber oil sea right end, which is successively arranged, is equipped with packing holder, and the packing holder right end, which is successively arranged, is equipped with roller gear
Circle, and the bearing bowl of press fitting have gasket between the bearing bowl inside and cross axle, the angle of cross axis connection described in four groups
Place is provided with the first lubricating cup, and the cross axle two sides are additionally provided with roller.
Preferably, the cross axle includes at least spindle nose, and the spindle nose is arc-shaped structure, the outermost end cap of cross axle
Equipped with bearing bowl, ball is provided between the spindle nose and bearing bowl.
Preferably, it is provided with the second lubricating cup on the closed end of the bearing bowl outer wall, is offered on the inside of second lubricating cup
Oil transportation mouth, and oil transportation mouth is connected to cross axle and oil transportation mouth fit inside is equipped with bolt.
Preferably, the skeleton rubber oil sea 3 is arranged with two groups on the outside of one group of cross axle 10 altogether.
The technical effect and advantage of the utility model: the modified cross assemble, by increase labyrinth sealing lid and
After packing holder, so that rotation axis cross axle is sealed to double skeleton rubber oil seas and the combined type of labyrinth sealing composition is close
Envelope extends Wrapping Roll WSP type rotation axis physical life, since spindle nose is cambered design, so the contact point of ball and roller
It is less, spindle nose can in this way moved more smooth in bearing bowl, increase the second lubricating cup, conducive to the profit for promoting cross axle
Slip prolongs the service life, the modified cross assemble, structurally reasonable using Combination nova Seal Design, long service life,
It can be widely used.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；

In figure: 1 first lubricating cup, 2 labyrinth sealing lids, 3 skeleton rubber oil seas, 4 packing holders, 5 spindle noses, 6 rollers gear
Circle, 7 bearing bowls, 8 gaskets, 9 rollers, 10 cross axles, 12 balls, 13 bolts, 14 oil transportation mouths, 15 second lubricating cups.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of modified cross assemble as shown in Figs. 1-3, including the first lubricating cup 1, labyrinth
Formula sealing cover 2, cross axle 10 and bearing holder (housing, cover) 11, the cross axle 10 circularize array and are provided with four groups, outside the cross axle 10
End cap is equipped with labyrinth sealing lid 2,2 right end of labyrinth sealing lid is successively arranged and is equipped with skeleton rubber oil sea 3, described
Skeleton 3 right end of rubber oil sea, which is successively arranged, is equipped with packing holder 4, and 4 right end of packing holder, which is successively arranged, is equipped with rolling
Column retaining ring 6, and the bearing bowl 7 of press fitting have gasket 8, cross axle described in four groups between 7 inside of bearing bowl and cross axle 10
The angle of 10 connections is provided with the first lubricating cup 1, and 10 two sides of cross axle are additionally provided with roller 9, double skeleton rubber oil seas 3
With the combined labyrinth and carbon gland of labyrinth sealing composition, extend Wrapping Roll WSP type rotation axis service life.
Specifically, the cross axle 10 includes at least spindle nose 5, the spindle nose 5 is arc-shaped structure, and the cross axle 10 is most
Outer end is arranged with bearing bowl 7, is provided with ball 12 between the spindle nose 5 and bearing bowl 7, since spindle nose 5 is cambered design, so
