With fixing hole, the screwed hole of circle distribution is additionally provided with the agent structure on the outside of the mounting boss, it is characterised in that：
The end face of the mounting boss is provided with the seal groove of cylindrical distribution, and the section of the seal groove is triangle, the sealing
The depth of groove is less than the height of the mounting boss, and the center of the sealed step is provided with back taper pilot hole, it is described fall
Positive taper hole is provided with the inside of taper pilot hole, the back taper pilot hole is identical with the maximum taper bottom surface in the positive taper hole,
Face where the taper of the back taper pilot hole is less than the taper in the positive taper hole, the bosom in the positive taper hole with it is described
At grade, the position that the sealed step is connected with the agent structure is uniform provided with 3 for seal groove innermost position
Locating dowel that is being distributed and being formed in one.
Further, the height of the mounting boss is less than the height of the agent structure, the positioning fixing lug boss
Highly it is less than the height of the mounting boss, the height of the sealed step is 1mm.
Further, the quantity of the screwed hole is 6, is uniformly distributed using the center of the agent structure as axle center, institute
Stating screwed hole is made in the way of nut is crimped.
Beneficial effects of the present invention：
Structural strength of the present invention is higher, and being set by the sealing structure of multiple positions makes overall sealing property obtain higher
Lifting, and in link position by setting reverse taper hole, make its connective stability more preferably, more stable when in use, peace
Full property is higher, and making hydraulic pump, performance is more preferable when in use, and service life is longer.
