Description
Technical field
This utility model relates to a kind of end cover, particularly relates to a kind of motor end cover, belongs to hydraulic pressure horse
Reach technical field.
Background technology
At present, in hydraulic motor end cover sealing structure, generally using end cap to combine O, bolt reinforcing is twisted
Tightly sealing, the weak point that this structure is primarily present has: structure is more complicated, and part is various, installs numerous
Trivial, cost is high.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of simple in construction, easy for installation, stability
High, the end cover of low cost, solves employing end cap and combines O, and bolt reinforcing is tightened and sealed,
The structure of this structure is more complicated, and part is various, installs loaded down with trivial details, the problem that cost is high.
In order to solve above-mentioned technical problem, the technical solution of the utility model there is provided a kind of end cover, its
It is characterised by, for open circles bucket body structure, by outside cylinder with end face is one-body molded constitutes, described cylinder
Inner surface is provided with the first rubber layer, and end face inner surface is provided with the second rubber layer, and the second rubber layer is provided with a circle half
Spheroid rubber layer.
Preferably, the thickness of described cylinder is more than the first rubber layer thickness.
Preferably, the thickness of described end face is more than the second rubber layer thickness.
Preferably, described hemisphere rubber layer is higher than the second rubber layer of end face inner surface.
This utility model simple in construction, part are easy to process, easy for installation, low cost, serviceability are the most steady
Fixed, conventional is combined O by end cap by it, and bolt reinforcing is tightened and carried out sealing means and change into by close
End-blocking lid is directly and motor shell closely cooperates and punching press riveting point, has both been easily installed operation, in turn ensure that sealing effect
Really.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of end cover；
Fig. 2 is the close-up schematic view of Fig. 1.
Detailed description of the invention
For making this utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
This utility model is a kind of end cover, and as shown in Figure 1 and Figure 2, this end cover is open circles staving
Structure, by outside cylinder 1 with end face 4 is one-body molded constitutes；Cylinder 1 inner surface is provided with the first rubber layer 2,
The thickness of cylinder 1 is more than the first rubber layer 2 thickness.End face 4 inner surface is provided with the second rubber layer 5, end face 4
Thickness more than the second rubber layer 5 thickness.Second rubber layer 5 of end face 4 inner surface is provided with a circle hemisphere
Rubber layer 3.Second rubber layer 5 higher than end face 4 inner surface of hemisphere rubber layer 3.
Motor end cover of the present utility model in use, by the first rubber layer 2 of cylinder 1 inner surface
Couple with motor shell seam tight fit, by the circle hemisphere on the second rubber layer 5 of end face 4 inner surface
Rubber layer 3 and motor shell end face compact siro spinning technology, by having groove on motor shell seam, to end cover
Cylinder 1 outer surface carry out punching press riveting point, by the combination of above 3 kinds of modes, effectively carried out motor-end
Lid seals, and guarantees that this end cap in use will not loose or dislocation.
