Abstract
The utility model discloses a crank shaft box casing which comprises a crank shaft box casing body (1), two adjacent screw holes (2) are arranged on the left lateral casing face of the crank shaft box casing body (1), and a boss (3) is arranged above one side of the screw hole (2). The crank shaft box casing improves connection strength between a crank shaft box and a support, reduces shock of the crank shaft box on the automobile, reduces noise, enables the crank shaft box to be stable in operation and improves fuel oil efficiency.
Description
Technical field
The utility model relates to field of machining and machinebuilding technology, is specifically related to a kind of shell of crankcase.
Background technique
Crankcase can directly cause its vibrations larger because it is comparatively loosening with being connected of support in the process of work, also can produce larger noise after long-time the use, and fuel efficiency is lower.
Summary of the invention
The utility model purpose provides a kind of shell of crankcase, and it can solve existing problem in the background technique effectively.
In order to solve existing problem in the background technique, it comprises crankcase shell 1, and the left side shell face of this crankcase shell 1 is provided with two adjacent screws 2, is provided with boss 3 near the top of described screw 2 one sides.
Owing to adopted above technological scheme, the utlity model has following beneficial effect: strengthened the join strength between crankcase and the support, reduced the vibrations of crankcase on automobile, reduced noise, it is also more steady that crankcase is moved, and improved fuel efficiency.
Description of drawings
In order to be illustrated more clearly in the utility model, the below will be to doing simple introduction to embodiment by reference to the accompanying drawings.
Fig. 1 is plane structure schematic representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, the accompanying drawing below in conjunction with among the utility model embodiment is clearly and completely described the technological scheme among the utility model embodiment.
Referring to Fig. 1, this embodiment is to be achieved by the following technical solutions, it comprises crankcase shell 1, and the left side shell face of this crankcase shell 1 is provided with two adjacent screws 2, the join strength between strong crankcase and the support, be provided with boss 3 near the top of described screw 2 one sides, between this boss 3 and the support mutually socket cooperate, reduced the vibrations of crankcase on automobile, reduced noise, it is also more steady that crankcase is moved, and improved fuel efficiency.
Claims (1)
