Abstract
The utility model relates to a separating and lubricating device for a two-stroke gasoline motor, which mainly comprises an air cylinder, a piston, a crankshaft, and a crankcase, wherein, a cylinder body is provided with a lubricating oil hole, the lubricating oil hole is arranged on a straight line for the move of a piston pin hole and is positioned at the relative position of a piston pin when the piston moves to a lower dead point; the lubricating oil hole is communicated with the crankcase via a lubricating oil pipe and a lubricating oil passage; the bottom part of the crankcase is provided with machine oil, and the lubricating oil pipe is positioned below an oil surface. When the piston moves to a lower dead point, the piston pin hole is opposite to the lubricating oil hole, lubricating oil can be sprayed into the piston pin hole and can go into a crankshaft connecting rod head and a crankshaft bearing via a built-in lubricating oil passage. In the utility model, the purposes of separation and lubrication are achieved; moreover, the structure is simple, and the production cost is low.
Description
The utility model belongs to two-stroke gasoline engine lubrication system technical field, specifically relates to a kind of separation lubricating fitting.
Existing two-stroke gasoline engine, its lubricating system mainly contains Mixed lubrication and separates lubricated dual mode, for solving the problem of environmental pollution and lubricant oil waste, present most motor has adopted the lubricated mode of separating, comparatively advanced in the world absolute forced lubricating system, be by improving the supply of lubricant oil, machine oil, gasoline are separated, reach and both save lubricant oil, reduce the purpose of environmental pollution again, but this system need be equipped with oil pump, whole lubricating system complex structure, fabricating cost height.
The purpose of this utility model provides a kind of gasoline, machine oil of can not only making and separates, and two-stroke gasoline engine simple in structure separates lubricating fitting.
The utility model comprises cylinder body, piston, cylinder head, crankcase, bent axle, connecting rod, cylinder body is provided with oilhole, this oilhole is located on the straight line of piston operation, and when being positioned at piston and moving to lower dead center, on the relative position of piston pin hole, oilhole communicates with crankcase by oil leab and lubricant pipe, crankcase bottom is provided with lubricant oil, the oil pipe lower end is positioned at below the pasta, piston pin hole is connected with built-in lubrication channel on being located at connecting rod and bent axle, and passage communicates with the oilhole of big connecting rod head and crankshaft two end.
The utility model piston pin hole be located at connecting rod, built-in grease channel in the bent axle communicates, the oilhole that is positioned on the cylinder body is on the straight line of piston pin hole operation, and when being positioned at piston and moving to lower dead center, on the relative position of piston pin hole, therefore when piston runs down to lower dead center by top dead center, owing to have certain pressure in the crankcase, the lubricant oil that is located at the bottom of the case just enters oilhole through lubricant pipe and grease channel, and injection into pistion pin-and-hole, wherein a part of lubricant oil enters small end, and to the wrist pin lubricate, a part arrives the bearing of connecting rod tip and crankshaft two end through built-in lubrication channel, and play lubrication, adopt this mode, the lubricant oil supply changes with engine speed, has reduced the lubricant oil use amount, machine oil does not mix with gasoline, improved gasoline combustion efficient, reduced harmful gas emission, this device does not need special oil pump simultaneously, simple in structure, cost of production is low.
The utility model will be further described below in conjunction with drawings and Examples
