Abstract
The utility model relates to an assembly structure for assembling an engine body and a main bearing cover. The assembly structure for assembling the engine body and the main bearing cover comprises the engine body, the main bearing cover, and thrust plates, wherein thrust grooves are formed in a matching surface of the engine body and a matching surface of the main bearing cover, the thrust plates are arranged in the thrust grooves in the engine body and the main bearing cover, the thrust plate is in an up-down two-part structure, the thrust plate comprises a thrust plate alloy layer and a thrust plate steel backing, a thrust plate oil slot is formed in the thrust plate alloy layer, the thrust plate steel backing is in an one-piece structure, and the thrust slots in the engine body and the main bearing cover are all in rectangular check structures. According to the assembly structure for assembling the engine body and the main bearing cover, no hard spot is on the thrust plates within a range of a thrust surface of a crankshaft, so that axial bearing capacity of the thrust plates is effectively increased, the thrust plates are prevented from being broken, and the normal operation of an engine is not influenced.
Description
Technical field
The utility model belongs to the engine component technical field, particularly relates to the assembly structure of a kind of engine body and main bearing cap.
Background technique
In engine operation process, bent axle not just rotates, and axial motion trend is also arranged.Excessive when the axial clearance of bent axle, the bent axle axial float is large, and the oil film in main bearing can't form, and accelerates the wearing and tearing of bent axle and bearing.Simultaneously, the bent axle axial float produces excessive vibration (the particularly torsional vibration of bent axle), affects the stationarity of motor output.The effect of thrust plate is exactly that the adjustment crankshaft axial gap, prevent the bent axle axial float.When the thrust plate breaking releasing, motor will produce above problem, affects the normal use of motor.
Summary of the invention
The utility model provides a kind of engine body of crankshaft thrust collar bearing capacity and assembly structure of main bearing cap of increasing for solving the technical problem existed in known technology.
The technological scheme that the utility model is taked for the technical problem existed in the solution known technology is:
The assembly structure of a kind of engine body and main bearing cap, comprise engine body, main bearing cap and thrust plate, described engine body and main bearing cap fitting surface are provided with the thrust groove, described thrust plate is arranged in the thrust groove of engine body and main bearing cap, described thrust plate adopts the two-piece unit structure, described thrust plate comprises thrust plate alloy-layer and thrust plate steel backing, and described thrust plate alloy layer is provided with the thrust plate oil groove; The thrust groove of described engine body and main bearing cap all adopts the rectangle bit-stopping structure.
The utility model can also adopt following technical measures:
Described thrust plate steel backing adopts integrative-structure.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, thrust plate adopts new split-type structural, and the design of thrust plate steel backing employing integral type, has avoided thrust plate to concentrate and rupture because of processing groove stress; Main bearing cap and engine body thrust groove adopt new rectangle bit-stopping structure, have improved traditional processing technology, have increased the loaded area of thrust groove.When thrust plate is arranged in main bearing cap and body thrust groove while being used in conjunction with, in the crankshaft thrust face scope, the unstressed centrostigma of thrust plate, can effectively increase the thrust plate axial carrying capacity, prevents the thrust plate fracture, thereby do not affect the normal operation of motor.

Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 to Fig. 8, the assembly structure of a kind of engine body and main bearing cap, comprise engine body 1, main bearing cap 2 and thrust plate 3, described engine body 1 and main bearing cap 2 fitting surfaces are provided with thrust groove (1-1,2-1), described thrust plate 3 is arranged in the thrust groove (1-1,2-1) of engine body and main bearing cap, described thrust plate adopts the two-piece unit structure, described thrust plate comprises thrust plate alloy-layer 3-1, thrust plate steel backing 3-2, and described thrust plate alloy layer is provided with thrust plate oil groove 3-3; The thrust groove of described engine body 1 and main bearing cap 2 all adopts the rectangle bit-stopping structure, has improved traditional processing technology, has increased the loaded area of thrust groove.
For fear of thrust plate concentrate and to rupture because of processing groove stress, described thrust plate steel backing 3-2 adopts integrative-structure.
Said structure, in the crankshaft thrust face scope, the unstressed centrostigma of thrust plate, can effectively increase the thrust plate axial carrying capacity, prevents the thrust plate fracture, thereby do not affect the normal operation of motor.
Although the above is described preferred embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, can also make a lot of forms, within these all belong to protection domain of the present utility model.
