The machine oil of oily main oil gallery leakage channels to the groove of sealing surface.
Further, the groove is to the arcuate structure close to sealing surface side protrusion, and the port at groove both ends deviates from
Sealing surface.
Further, reinforcing rib is equipped in the lower section in the intake and exhaust side of the frame, flange face region.
Further, the frame installs bolt by main bearing seat and frame is installed bolt and is assembled on cylinder body, frame
Crankcase and crankshaft installed hole are collectively constituted with cylinder body.
Further, the frame, cylinder body, the joint face two-by-two between timing cover three are all made of anaerobic adhesive or silicon
Glue is sealed.
The advantages of using technical solutions of the utility model are as follows:
1, the sealing surface of the utility model can solve in the prior art, due to each part material thermal expansion coefficient not
Together, while frame front end is limited by timing cover, and rear end is limited by frame installation bolt, eventually leads to flange face deformation, occurs
The problem of permeability, the setting of sealing surface, which is equivalent to, is widened the flange face of frame roof, increase frame and cylinder body it
Between sealing surface；Sealing surface has double action, and first can be enhanced the rigidity at flange face, can effectively resist deformation；The
Two widen band, play the role of better seal.
2, the utility model groove plays the role of reinforcing sealing, once machine oil is scurried out, will return to song by groove
Axle box.
3, the setting of the utility model reinforcing rib prevents frame further to enhance the rigidity of frame roof flange face
Frame flange face bending deformation herein, thoroughly solves oil leakage problem.
