Abstract
The utility model relates to an engine component, in particular to a crank case which includes a base plate (1). The base plate is provided with an inner cylinder (2) which is used for installing a crank shaft. A lateral plate is arranged at the edge of the base plate to form an outer cylinder (3). The outer cylinder (3) is provided with a cylinder body (4); a first mounting hole (5) and a second mounting hole (6) are formed in the base plate (1). The crank case is characterized in that a first support plate (7) is arranged on the lateral surface of the base plate (1) between the inner cylinder (2) and the outer cylinder (3). Stiffness of the inner cylinder (2) is increased by arranging the first support plate (7) and the second support plate (9) on the lateral surface of the base plate (1) between the inner cylinder (2) and the outer cylinder (3) and by arranging a plurality of reinforcing ribs (8) at intervals on the inner lateral surface of the base plate (1) between the inner cylinder (2) and the outer cylinder (3) so as to improve soundness and reliability of the support crank shaft.
Description
Technical field
The utility model relates to a kind of engine pack, is specifically related to a kind of crankcase.
Background technique
At present, the crankcase of petrol engine comprises crankcase body and is arranged on the upper cylinder block of crankcase body, described crankcase body comprises base plate, be provided with on described base plate for the inner core that bent axle is installed, described bottom edge is provided with side plate and forms urceolus, and described cylinder block is arranged on described urceolus, when mounted, one end of bent axle supports by inner core and is arranged in inner core, and bent axle is connected with piston by connecting rod simultaneously, and piston is arranged in cylinder block.
When petrol engine is worked, because the piston in cylinder block is done to-and-fro motion at a high speed in cylinder block, piston axially produces movement inertia along cylinder block, thereby make petrol engine produce vibration, also inner core is impacted simultaneously, because the base plate on crankcase body is plate, thereby can not be solid and reliable inner core is supported on base plate, and then cause the displacement of bent axle, damage petrol engine and even cause serious security incident.
So need at present a kind of crankcase that can solid and reliable support inner core badly.
The model utility content
Goal of the invention of the present utility model is: for existing crankcase exist can not solid and reliable support inner core deficiency, a kind of crankcase that can solid and reliable support inner core is provided.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of crankcase, comprise base plate 1, be provided with on described base plate 1 for the inner core 2 that bent axle is installed, described base plate 1 edge is provided with side plate and forms urceolus 3, be provided with cylinder block 4 on described urceolus 3, also be provided with the first mounting hole 5 and the second mounting hole 6 on described base plate 1, be provided with the first dunnage 7 on base plate 1 inner side surface between described inner core 2 and described urceolus 3.Connect inner core 2 and urceolus 3 by the first dunnage 7, increased the rigidity of inner core 2, and then improved soundness and the reliability that supports bent axle.
As preferred version of the present utility model, also be arranged at intervals with some stiffening ribs 8 on base plate 1 inner side surface between described inner core 2 and described urceolus 3.Further improved the rigidity of inner core 2.
As preferred version of the present utility model, be provided with stiffening rib 8 on base plate 1 inner side surface between described the second mounting hole 6 and described the first dunnage 7, also be provided with another root stiffening rib 8 on base plate 1 inner side surface between described the second mounting hole 6 and the described wherein stiffening rib 8 that is connected inner core 2 and urceolus 3.Also improved the rigidity of inner core 2 when improving the rigidity of the second mounting hole 6.
As preferred version of the present utility model, also be provided with the second dunnage 9 on the outer side surface of the base plate 1 between described inner core 2 and described the first mounting hole 5 and the second mounting hole 6.Further improved the rigidity of inner core 2, the first mounting hole 5 and the second mounting hole 6.
Crankcase of the present utility model, by on base plate 1 side between inner core 2 and urceolus 3, the first dunnage 7 and the second dunnage 9 being set, and the interval arranges some stiffening ribs 8 on base plate 1 inner side surface between inner core 2 and urceolus 3, increased the rigidity of inner core 2, and then improved soundness and the reliability that supports bent axle, also increase the rigidity of the first mounting hole 5 and the second mounting hole 6, thereby improved the overall performance of crankcase.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
1, by on base plate 1 side between inner core 2 and urceolus 3, the first dunnage 7 and the second dunnage 9 being set, and the interval arranges some stiffening ribs 8 on base plate 1 inner side surface between inner core 2 and urceolus 3, thereby increased the rigidity of inner core 2, and then improved soundness and the reliability that supports bent axle.
2, increase the rigidity of the first mounting hole 5 and the second mounting hole 6, thereby improved the overall performance of crankcase.
