Abstract
The utility model discloses a motorbike engine crankshaft box body with an oil spraying hole. The box body wall of a cylinder combining position (1) of the crankshaft box body and a crankshaft hole (2) is provided with an oil spraying hole (3). The motorbike engine crankshaft box body leads an engine to spray lubricating oil into a cylinder sleeve automatically when in running by only opening a small oil spraying hole on the side wall of the crankshaft box body, so as to lubricate the cylinder sleeve and a piston, thus reducing the temperature of a cylinder body and the piston, reducing the wear between the cylinder sleeve and the piston and prolonging the service life thereof.
Description
Technical field
The utility model belongs to a kind of crankcase body structure of motorcycle engine, specifically, is a kind of crankshaft box of motorcycle engine body that has nozzle opening.
Background technique
Motorcycle engine is in the process of work, and the cooling of piston mainly relies on the heat transmission between itself and the cylinder wall outwards to dispel the heat, and piston lubricated is during only by crankshaft rotating, and the machine oil that has splashed is to piston lubrication.But because the oil level that splashes during crankshaft rotating is smaller, and the machine oil that has splashed can not drop on the piston inner wall skirt section usually exactly, makes machine oil relatively poor to the cooling effect of piston, fails effective lubricating and cooling.Can not well lubricate and lower the temperature, make the easily stuck and temperature of cylinder sleeve and piston raise the working life of having reduced cylinder sleeve and piston.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of crankshaft box of motorcycle engine body that can carry out the lubricated band nozzle opening of fuel feeding to cylinder body.
The technical solution of the utility model is as follows: a kind of crankshaft box of motorcycle engine body with nozzle opening, its key is: have nozzle opening on the cylinder junction of described crankcase body and the box body wall between the crankshaft hole.Above-mentioned nozzle opening is positioned on the right crankcase.During engine running, under the effect of gear chamber self pressure, machine oil is lubricated cylinder sleeve and piston in nozzle opening spirt cylinder sleeve, has improved cooling-down effect.Reduced the wearing and tearing of cylinder sleeve and piston space, also improve greatly its working life.
As the above-mentioned nozzle opening diameter of optimal design is 1 millimeter.
Beneficial effect: the utility model is only opened a slight nozzle opening at the crankcase body sidewall, make motor in the running, can be in the trend cylinder sleeve lubricating oil spraying, cylinder sleeve and piston are lubricated, reduce the temperature of cylinder body and piston, reduce the wearing and tearing of cylinder sleeve and piston space, improved its working life greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the connection diagram of the utility model and cylinder sleeve;
Fig. 3 is the partial enlarged drawing of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As Fig. 1, Fig. 2, shown in Figure 3, the crankshaft box of motorcycle engine body of the utility model band nozzle opening has diameter and is 1 millimeter nozzle opening 3 on the cylinder junction 1 of crankcase body and the box body wall between the crankshaft hole 2.Described nozzle opening 3 is opened on the right crankcase.
Claims (3)
1. the crankshaft box of motorcycle engine body with nozzle opening is characterized in that: have nozzle opening (3) on the cylinder junction (1) of described crankcase body and the box body wall between the crankshaft hole (2).
2. according to the crankshaft box of motorcycle engine body of the described band nozzle opening of claim 1, it is characterized in that: described nozzle opening (3) is positioned on the right crankcase.
3. according to the crankshaft box of motorcycle engine body of claim 1 or 2 described band nozzle openings, it is characterized in that: described nozzle opening (3) diameter is 1 millimeter.
