The model utility content
The purpose of this utility model is for the problems referred to above, and a kind of simple in structure and processing cost is low and structural strength is high oil hydraulic motor connecting cover is provided.
For achieving the above object, the utility model has adopted following technical proposal: this oil hydraulic motor connecting cover comprises lid in the form of annular discs, be provided with center hole in the lid axial centre, it is characterized in that, be provided with the first ring-shaped step that is positioned at one stomidium mouth place and the second ring-shaped step that links to each other with the first ring-shaped step in the described center hole, in center hole, be provided with the 3rd ring-shaped step and the Fourth Ring shape step that links to each other with the 3rd ring-shaped step that are positioned at its place, the other end aperture, be provided with circular groove at lid near an end of the 3rd ring-shaped step, the first screw that is provided with some even distributions and is communicated with described circular groove respectively at the lid sidepiece.Obviously, the utility model design is more reasonable, simple in structure and easy manufacturing, and low cost of manufacture and easily installation and removal, in addition, its structural strength is very high, and working life is longer, can reduce user cost, can satisfy usage requirement equally.
In above-mentioned oil hydraulic motor connecting cover, described lid is located by fixed structure.Be easy to install the location.
In above-mentioned oil hydraulic motor connecting cover, described fixed structure comprises that some even circumferentials are distributed in the fixed hole near the 3rd ring-shaped step one end.
In above-mentioned oil hydraulic motor connecting cover, described lid is provided with the second screw that some even circumferentials distribute away from an end face of the 3rd ring-shaped step, and described the second screwhole diameter is greater than described the first screwhole diameter.
In above-mentioned oil hydraulic motor connecting cover, described lid is made by the spheroidal graphite cast iron casting.
Compared with prior art, the advantage of this oil hydraulic motor connecting cover is: it is more reasonable to design, simple in structure and easy manufacturing, low cost of manufacture and easily installation and removal, in addition, its structural strength is very high, working life is longer, can reduce user cost, can satisfy usage requirement equally.
