Description
Technical field
A kind of glossy construction of the present invention on engine timing sprocket, especially can make timing sprocket to obtain enough profits
Lubricating oil is glossy and cools, and can lift the glossy construction of the engine timing sprocket using effect of engine.
Background technology
The glossy construction of engine timing sprocket is related to, such as TWI299380 Patent Cases, is referred to shown in Fig. 1, main system
In setting a camshaft 12 on the cylinder head 11 of engine 1, the camshaft 12 is provided with least one cam 121, and in cam 12
Two sides be arranged bearing 122, separately in providing a lubricating oil in the fixed timing sprocket 14 in the side of timing chain room 13, the camshaft 12
Main channel 123, and open up the first subaisle 124 on main channel 123 and the second subaisle 125, the first passage 124 go out
Mouthful 1241 systems are located on cam 121, and thereby, after lubricating oil is transfused to camshaft 12, lubricating oil can be by main channel 123 through the
One subaisle 124, flowed out from outlet 1241 by cam 121, use lubrication cam 121 and the inlet and outlet valve contacted with cam 121
The rocking arm (not drawn in schema) of door.
The system of second subaisle 125 at the nearly timing sprocket 14, i.e., positioned at the first subaisle 124 and timing sprocket 14 it
Between, the system of outlet 1251 of second subaisle 125 is on camshaft 12, thereby, after lubricating oil is transfused to camshaft 12, portion
The lubricating oil divided is flowed out by the first subaisle 124, and parts of lubricating oil can be rotated by main channel 123 by camshaft 12, be produced
Raw centrifugal force sprays from the outlet 1251 of the second subaisle 125, and the lubricating oil flows out from the outlet 1251 of the second subaisle 125
Afterwards, part can be just sprayed on timing sprocket 14, thereby timing sprocket 14 can be made to be lubricated.
TWI299380 Patent Cases, the timing sprocket 14 is set to obtain the lubrication of lubricating oil by above-mentioned glossy mode.
Only, the system of outlet 1251 of second subaisle 125 is on camshaft 12, and the system of outlet 1251 of second subaisle 125
Set towards above-below direction, therefore the lubricating oil rotates by camshaft 12, caused centrifugal force goes out from the second subaisle 125
After mouth 1251 sprays, actual ejection is limited in the oil mass of the lubricating oil on timing sprocket 14, and the lubricating oil oil mass is still insufficient
So that the timing sprocket 14 obtains glossy and has the function that cooling by lubricating oil.
Therefore the timing sprocket is obtained enough lubricating oil and carry out effect that is glossy and reaching cooling by lubricating oil
Fruit, actually a motorcycle dealer big problem urgently to be resolved hurrily.
