Abstract
A kind of mini four-stroke gasoline engine box body split-type structural, belongs to miniature gasoline engine technical field.Comprise cylinder head (1), cylinder (2), crankcase body (3), bent axle (4), machine oil case lid (5), its feature is made up of first half crankcase body (6) and later half crankcase body (7) at crankcase body (3); Machine oil case lid (5) forms lubricant oil apotheca (8) with later half crankcase body (7).One of its structure is described first half crankcase body (6) and later half crankcase body (7) and cylinder (2) formation crankshaft-link rod chamber (9) and cylinder chamber (10).The utility model makes crankcase body die casting, surface Machining saving of work and time, and makes cylinder, crankcase body, bent axle three's installation easy to assembly, simple, and easy to maintenance in the time that piston and bent axle break down.In addition, this structure also makes to bring simplification, convenient with cylinder processing, assembling and the maintenance of crankcase body Assembly.
Description
Technical field
The utility model patent relates to miniature gasoline engine technical field. specifically refer to a kind of mini four-stroke gasoline engine box body split-type structural.
Background technique
Existing mini four-stroke gasoline engine upper crankcase body is an entirety, there is following disadvantage in this structure, the one, overall crankcase body is because of complex structure, die casting, surface Machining are time-consuming, the 2nd, on the cylinder and the crankcase body that connect, piston is installed and bent axle is time-consuming, the 3rd, work as piston and the bent axle maintenance difficult that breaks down.As notification number: CN202659300U " mini four-stroke gasoline engine ", it comprises cylinder body, piston in combination, firing chamber, bent axle, crankcase, it is characterized in that: described crankcase top is connected with cylinder body.Above-mentioned description explanation crankcase is an entirety.
Summary of the invention
The purpose of this utility model is that a kind of mini four-stroke gasoline engine box body split-type structural will be provided, and it can overcome existing mini four-stroke gasoline engine crankcase is the disadvantage such as the existing processing of an overall structure and assembling difficulty, maintenance inconvenience.
Above-mentioned goal of the invention is to realize by following technical proposal: a kind of mini four-stroke gasoline engine box body split-type structural, comprise cylinder head, cylinder, crankcase body, bent axle, machine oil case lid, its main points are to be made up of first half crankcase body and later half crankcase body at crankcase body; Machine oil case lid and later half crankcase body form lubricant oil apotheca.
As preferably, described first half crankcase body and later half crankcase body and cylinder form crankshaft-link rod chamber and cylinder chamber; Later half crankcase and machine oil case lid form oil chamber.
The utility model makes crankcase body die casting, surface Machining saving of work and time, and makes cylinder, crankcase body, bent axle three's installation easy to assembly, simple, and easy to maintenance in the time that piston and bent axle break down.In addition, this structure also makes to bring simplification, convenient with cylinder processing, assembling and the maintenance of crankcase body Assembly.
