Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0015] Such as figure 1 As shown, as the first embodiment of the present invention, a crankcase body includes a box body 1 and a cylinder block 3, the box body is provided with a turning section 5, and the middle part of the box body 1 A crankshaft hole sleeve 2 is provided, and a base 8 is provided at the bottom of the box body 1. A plurality of reinforcing ribs 4 are arranged on the outside of the crankshaft hole sleeve 2 in a divergent shape, and one end of the reinforcing rib 4 is connected to the crankshaft hole. The corresponding position of the outer edge of the sleeve 2 is connected to the corresponding position of the inner wall of the folded section 5 at the other end. The lower plane of the reinforcing rib 4 has a certain height from the inner wall of the box body 1, and at least one of the reinforcing ribs 4 has a certain height. At least one vib...

Abstract

The invention relates to the field of general gasoline engine manufacturing, in particular to a crankshaft box. According to the technical scheme adopted by the invention, the crankshaft box comprises a box body and an air cylinder body; the box body is provided with a folding section; the middle of the box body is provided with a crankshaft hole sleeve; the lower portion of the box body is provided with a base; the outer side of the crankshaft hole sleeve is provided with a plurality of reinforcing ribs in a divergent shape; one ends of the reinforcing ribs are connected to corresponding positions of the outer edge of the crankshaft hole sleeve, and the other ends of the reinforcing ribs are connected with corresponding positions of the inner side wall of the folding section; a certain height is formed between the lower planes of the reinforcing ribs and the inner wall of the box body; at least one vibration absorption structure is installed on at least one reinforcing rib; and the bottom of the crankshaft box is provided with a row of fooling fins parallel to one another, and the top ends of the cooling fins and the box body are integrally connected. The crankshaft box has the advantages that vibration, produced in the working process, of parts inside the crankshaft box can be absorbed, so that a gasoline engine is reliable in operation and low in failure rate, and the service life of the gasoline engine can be prolonged.

Description

technical field [0001] The invention relates to the field of general gasoline engine manufacture, in particular to a crankcase body. Background technique [0002] Usually the crankcase body of engine is the important constituent part of power plant such as engine, and crankcase body comprises two parts of casing and the cylinder block that is integrated with casing. The function of the box body is to install the crankshaft, which plays an important role in the operation of the engine. The existing crankcase has a simple structure and a relatively single function, which cannot meet the use requirements. Therefore, a new technical solution should be provided to solve the above technical problems. Contents of the invention [0003] The object of the present invention is to provide a crankcase with reasonable structure and good use effect in view of the above-mentioned deficiencies. [0004] In order to achieve the above object, the technical scheme adopted in the present i...
