Control system for tapered lubricating system

Abstract

The invention provides a control device for a tapered lubricating system, and belongs to the technical field of mechanism design. The device comprises a control cavity, a valve body, a filling body, a fixing body, through tubes, a spring, a rotating block, a rotating plate, a connecting plate, a rotating shaft and a connecting tube, wherein the lower section of the valve body is tapered; four ribs are arranged in the middle part of the valve body; outer threads are formed in the upper section of the valve body; a first through tube and a second through tube are arranged on the fixing body; the cross section area of the first through tube is less than that of the second through tube; one end of the connecting tube is communicated with the first through tube and while the other end of the connecting tube is communicated with an air feeding tube of an engine; when the pressure of the air feeding tube of the engine is high, the valve body upwards moves, a main oil channel is separated from an oil returning tube, and then the pressure of the engine oil in the main oil channel is increased; when the pressure in the air feeding tube of the engine is small, the valve body downwards moves, the main oil channel is communicated with the oil returning tube, and then the pressure of the engine oil in the main oil channel is reduced. The device is reasonable in design, simple in structure, and suitable for optimization design of a mechanical lubricating system.

Description

technical field [0001] The invention relates to a lubricating adjustment system in the technical field of mechanical design, in particular to a conical lubricating system control device suitable for supercharged engines. Background technique [0002] When the engine is working, the speed is very high, and the parts between the piston and the cylinder wall, between the connecting rod bearing bush and the crankshaft are tightly matched. If these matching parts are not fully lubricated, dry friction will occur. The heat generated by dry friction in a short period of time is enough to melt the metal, causing damage or even jamming of the parts (piston scuffing, crankshaft pads, etc.), so the matching parts in the engine must be well lubricated. When the lubricating oil flows to the mating part, an oil film will be formed on the friction surface. In order to ensure that the lubricating oil can reach the mating surface smoothly, the engine lubricating oil must have a certain pres...
