In order to realize the utility model discloses a purpose, the utility model discloses a technical scheme do:
the utility model discloses a transmission shaft high speed grease that economizes on fuel seals blanking cover structure, including the blanking cover body, the blanking cover body is the circular structure that one side evagination formed the recess, the blanking cover body passes through the interference fit pressure equipment on the one end terminal surface of high-speed festival, the other end of high-speed festival passes through rubber sheath and seals.
The groove opening part of blanking cover body is equipped with the outer fringe that is ring structure, the equidistant a plurality of blanking cover bolt holes that are equipped with on the outer wall of outer fringe, the blanking cover bolt hole with bolt hole on high-speed festival, the transaxle flange is coaxial, the transaxle flange with the terminal surface of high-speed festival links to each other.
Six blanking cover bolt holes are formed in the outer wall of the outer edge at equal intervals.
And a plurality of concave parts are arranged at the joint of the outer edge and the plugging cover body at equal intervals.
The outer end of the outer edge is provided with a limiting plate connected with the outer edge, the cross section of the limiting plate is of an annular structure, and the longitudinal section of the limiting plate is parallel to the axis of the plug cover body.
The beneficial effects of the utility model reside in that:
(1) the utility model discloses the assembly is easier, and can guarantee that the high-speed section does not leak the grease, and dustproof and waterproof that also can be fine, sealing performance is more excellent, and life is longer.
Drawings
Fig. 1 is a first schematic structural diagram of the present invention;
FIG. 2 is a second schematic structural view of the present invention;
fig. 3 is a sectional view of the usage state of the present invention.
In the figure: the sealing structure comprises a sealing cover body 1, a groove 11, an outer edge 12, an inner concave part 13, a limiting plate 14, a driver flange 2, a high-speed joint 3, grease 4, a rubber sheath 5 and a sealing cover bolt hole 6.
Detailed Description
The following further description of the present invention:
referring to figures 1-3 of the drawings,
the utility model discloses a transmission shaft high speed grease that economizes on fuel seals blanking cover structure, including blanking cover body 1, blanking cover body 1 is the circular structure that one side evagination formed recess 11, blanking cover body 1 passes through the interference fit pressure equipment on the one end terminal surface of high-speed festival 3, the other end of high-speed festival 3 passes through rubber sheath 5 and seals, plays sealed effect, can prevent effectively that the grease from leaking, dustproof waterproof that also can be fine.
The opening part of the groove 11 of the plug body 1 is provided with an outer edge 12 which is of an annular structure, a plurality of plug bolt holes 6 are arranged on the outer wall of the outer edge 12 at equal intervals, the plug bolt holes 6 are coaxial with bolt holes in the high-speed joint 3 and the drive axle flange 2, the drive axle flange 2 is connected with the end face of the high-speed joint 3, the plug bolt holes 6 of the outer edge 12 are easily aligned, and the assembly is easy.
Six blanking cover bolt holes 6 are arranged on the outer wall of the outer edge 12 at equal intervals, correspond to the number of the bolt holes in the drive axle flange 2 and the high-speed joint 3 in the axial direction, are easy to align and are easy to assemble.
The outer edge 12 and the connection part of the plug body 1 are provided with a plurality of concave parts 13 at equal intervals, so that the connection strength of the outer edge 12 and the plug body 1 can be enhanced.
The outer end of the outer edge 12 is provided with a limiting plate 14 connected with the outer edge, the cross section of the limiting plate 14 is of an annular structure, the longitudinal section of the limiting plate is parallel to the axis of the plug body 1, and the limiting plate 14 is arranged to further facilitate assembly.
