AI Technical Summary
The existing camshaft bushings are not effective when lubricating and lack the function of collecting and reusing lubricant oil, resulting in low reuse rate and low practicality of lubricant oil.
A camshaft bushing including a main body, a first oil inlet, a first oil storage chamber, a second oil storage chamber, a lubricating chamber and a third oil storage chamber are designed. Entering the first oil storage chamber and the second oil storage chamber through the first oil inlet, the lubricating oil flows into the lubricating chamber in the oil supply chamber for lubrication, and the lubricating chamber is in an X-shaped cross shape to improve the lubricating range. When the lubricating oil overflows, it enters the third oil storage chamber through the second oil inlet and reuses the lubricating oil through the oil outlet.
It improves the lubricating effect, increases the reuse rate of lubricating oil, and significantly improves the practicality of the camshaft bushing.
