Abstract
A thin-wall multi-rib aluminum alloy crankcase of a single-cylinder diesel comprises a case body, wherein a front main bearing hole, a rear main bearing hole, a cylinder liner mounting hole and a oil pan are arranged on the case body; a crankcase inner chamber and a gear chamber are also arranged in the case body; reinforcing ribs are arranged on two sides of the surfaces where the front main bearing hole, the rear main bearing hole and the cylinder liner mounting hole are formed, the outer surface of the oil pan, the top surface of the crankcase inner chamber, the surface where the gear chamber is arranged, and the inner cavity surface of the gear chamber. With the multiple reinforcing ribs arranged on the case body, the case body can be made of aluminum alloy, so that the weight of the crankcase can be greatly reduced; and due to the arrangement of the reinforcing ribs, the strength and rigidity of the crankcase can be guaranteed.
Description
(1) technical field
The utility model relates to a kind of single cylinder diesel crankcase.
(2) background technique
Single cylinder diesel is the series model that has a large capacity and a wide range in China's small-bore diesel engine system, its crankcase (body) mostly is the cast iron structure, structure weight is bigger than normal, generally account for 25～35% of Diesel Engine Complete Machine nt wt net weight, badly influence the specific mass index exceeding standard of " efficient single cylinder diesel general technical specifications " regulation.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing single cylinder diesel crankcase, the utility model provides a kind of many muscle of single cylinder diesel thin-walled aluminum alloy crankcase that adopts aluminum alloy, and still can keep corresponding rigidity and intensity.
The technical scheme in the invention for solving the technical problem is: many muscle of single cylinder diesel thin-walled aluminum alloy crankcase, comprise casing, described casing is provided with front main bearing hole, rear min bearing hole, mounting hole of cylinder sleeve, oil sump, also have crankcase intracavity and gear chamber in the described casing, be equipped with stiffening rib on the inner cavity surface of the outer surface of the both sides of the both sides of place, described front main bearing hole face, place, rear min bearing hole face, the both sides on plane, mounting hole of cylinder sleeve place, oil sump, the end face of crankcase intracavity, gear chamber place face, gear chamber.
Further, the wall thickness of described casing is 2.5～6mm.
Further, the stiffening rib of the both sides of the stiffening rib of the both sides of place, described front main bearing hole face, place, rear min bearing hole face includes ring-type rib, radial rib, and described ring-type rib and radial rib intersect.
Further, the stiffening rib of the stiffening rib of the stiffening rib of the stiffening rib of the stiffening rib of the both sides on plane, mounting hole of cylinder sleeve place, the outer surface of oil sump, the end face of crankcase intracavity, gear chamber place face, the inner cavity surface of gear chamber includes horizontal bar and perpendicular muscle, and described horizontal bar and perpendicular muscle intersect to form rectangular mutually.
The beneficial effects of the utility model are: after many stiffening ribs were set on the casing, casing can adopt aluminum alloy, can alleviate the weight of crankcase greatly, and because the existence of stiffening rib, had guaranteed the intensity and the rigidity of crankcase.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the present utility model of another angle.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, many muscle of single cylinder diesel thin-walled aluminum alloy crankcase, comprise casing, described casing is provided with front main bearing hole 1, rear min bearing hole 2, mounting hole of cylinder sleeve 3, oil sump 4, also have crankcase intracavity and gear chamber 5 in the described casing, be equipped with stiffening rib on the inner cavity surface of the end face 6 of the both sides on the both sides of described front main bearing hole 1 place face, the both sides of rear min bearing hole 2 place faces, plane, mounting hole of cylinder sleeve 3 place, the outer surface of oil sump 4, crankcase intracavity, gear chamber 5 place faces, gear chamber 5.After many stiffening ribs were set on the casing, casing can adopt aluminum alloy, and the wall thickness of casing can be accomplished 2.5～6mm, can alleviate the weight of crankcase greatly, and because the existence of stiffening rib, had guaranteed the intensity and the rigidity of crankcase.
In the present embodiment, the stiffening rib of the stiffening rib of the both sides of described front main bearing hole 1 place face, the both sides of rear min bearing hole 2 place faces includes ring-type rib, radial rib, and described ring-type rib and radial rib intersect.The stiffening rib of the inner cavity surface of the stiffening rib of the stiffening rib of the stiffening rib of the both sides on plane, mounting hole of cylinder sleeve 3 place, the outer surface of oil sump 4, the end face 6 of crankcase intracavity, the stiffening rib of gear chamber 5 place faces, gear chamber 5 includes horizontal bar and perpendicular muscle, and described horizontal bar and perpendicular muscle intersect to form rectangular mutually.
