Technical field
The utility model relates to a kind of diesel engine connecting bar.
Background technique
Diesel engine connecting bar is the connected element that connects crankshaft and piston on the diesel engine; Connecting rod carries the effect of fitted load such as bush gap and bolt pretightening and alternate loads such as gas blow-through power and inertial force in movement process; If connecting rod lubrication effect in use is good inadequately; Not only the Oscillation Amplitude of diesel engine is big and noise is big, and can shorten the working life of connecting rod.
The model utility content
The utility model technical problem to be solved is: the diesel engine connecting bar that a kind of high lubricating effect, long service life are provided.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of diesel engine connecting bar comprises: shaft; Shaft one end is provided with the piston attachment hole; Be provided with lining in the piston attachment hole, the shaft the other end is provided with connecting rod cap, and connecting rod cap is provided with the bearing shell mounting hole; Connecting rod cap comprises connecting rod lower cover and connecting rod loam cake; Faying surface between connecting rod lower cover and connecting rod loam cake and connecting rod loam cake and the shaft is perpendicular with the central axis of shaft respectively, and shaft is provided with the oilhole of axial perforation, and the piston attachment hole hole wall of described shaft is provided with the first fuel feeding groove; Described shaft is provided with some oil storage holes that are communicated with the first fuel feeding groove; Circumferentially be provided with some through holes that are connected with the first fuel feeding groove on the described jacket wall, the bearing shell mounting hole hole wall of described connecting rod cap is provided with the second fuel feeding groove, and the connecting rod loam cake is provided with the oil duct that is communicated with the shaft upper oil hole and the second fuel feeding groove.
Described connecting rod lower cover is fixedly connected through the high tenacity connecting bolt with the connecting rod loam cake.Described connecting rod shank is fastenedly connected through high tenacity connecting bolt and connecting rod cap.
Be respectively arranged with the assembling and positioning pin between described shaft and connecting rod loam cake, connecting rod lower cover and connecting rod loam cake.
The utility model has the advantages that: that diesel engine connecting bar is carried out fuel feeding is lubricated owing to be provided with oilhole, oil storage hole, oil duct and fuel feeding groove; Make the lubrication effect of diesel engine connecting bar better; Prolong the working life of connecting rod and bent axle, and reduced the Oscillation Amplitude and the noise of diesel engine.
Because diesel engine connecting bar is the three stage structure of shaft, connecting rod loam cake, connecting rod lower cover, and is respectively arranged with the assembling and positioning pin between shaft and connecting rod loam cake, connecting rod lower cover and connecting rod loam cake, makes the installation of diesel engine connecting bar more easy.
