Abstract
The utility model discloses a main bearing cover of an engine, wherein raised thrust faces are arranged at two sides of a crankshaft hole of the engine main bearing cover; the edges of the thrust faces fit the arc-shaped edge of the crankshaft hole. The main bearing cover of an engine has thrust function, is simple to assemble and has lower cost.
Description
Technical field
The utility model relates to the engine cylinder system, relates in particular to the main bearing cap of motor.
Background technique
The thrust function of present most of motors all is by 2 or 4 thrust plates realizations.The groove of thrust plate is installed in one of processing on cylinder body or main bearing cap, and thrust plate is packed in the groove, realizes the thrust function.The thrust plate assembling is complicated, and cost is than higher.
The model utility content
The technical problems to be solved in the utility model is to realize a kind of main bearing of engine lid that has the thrust function.
To achieve these goals, the technical solution adopted in the utility model is: a kind of main bearing of engine lid, cover the thrust surface that the crankshaft hole both sides are provided with protrusion, described thrust surface edge applying crankshaft hole curved edge at main bearing of engine.
Described thrust surface is a semi-round ring shape.
Described thrust surface surface is provided with quench hardened case.
Crankshaft hole one end of main bearing of engine lid is provided with two bolt of main bearing cap holes.
Advantage of the present utility model is to realize that the main bearing of engine lid has the thrust function, and assembling is simple, and cost is lower.
Description of drawings
Below the content of each width of cloth accompanying drawing expression of the utility model specification and the mark among the figure are made brief description:
Fig. 1 is main bearing of engine lid structural representation;
Fig. 2 is the plan view of main bearing of engine lid shown in Figure 1;
Fig. 3 is the side view of main bearing of engine lid shown in Figure 1;
Mark among the above-mentioned figure is: 1, crankshaft hole; 2, bolt of main bearing cap hole; 3, thrust surface.
Embodiment
Referring to the described main bearing of engine lid of Fig. 1-3 structural representation as can be known, main bearing of engine lid of the present utility model, crankshaft hole 1 one ends of main bearing of engine lid are provided with two bolt of main bearing cap holes 2, the thrust surface 3 of protrusion is set in crankshaft hole 1 both sides, this thrust surface 3 replaces former thrust plate function, thrust surface 3 is a semi-round ring shape, and ring edge applying crankshaft hole 1 curved edge in it, these two thrust surfaces 3 are done quenching heat treatment makes its surface formation quench hardened case increase wear resistance.
