Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Example one
The crankcase flange part is connected with an automobile engine to transmit the torque of a main shaft of the engine, a first connecting hole is formed in the engine, and a second connecting hole 12 corresponding to the first connecting hole is formed in the flange part as shown in fig. 7; when the position of the first connecting hole on the engine is changed, the position of the second connecting hole 12 of the flange part of the crankcase also needs to be correspondingly changed, the existing crankcase is used as an integral mechanism, and when the position of the second mounting hole 12 is changed, the mold opening of the whole crankcase needs to be carried out again, so that the cost is high.
Referring to fig. 1, a cross-sectional view of a novel detachable crankcase structure flange element is shown, and a mounting seat 9 is arranged on the flange element 1.
As shown in fig. 1 and 2, an annular projection 11 is provided on the mount 9, a first passage is formed inside the annular projection 11, and an axis of the annular projection 11 is parallel to a first direction; the first mounting hole 2 is provided on the mounting seat 9, and the first mounting hole 2 penetrates the flange member 1 in a first direction, and the first mounting hole 2 is provided around an axis of the annular protrusion 11, the first direction being a horizontal direction in fig. 2.
