Description
Technical Field
The invention relates to the technical field of engine lubrication, in particular to a lubricating structure of a rotary engine.
Background
As shown in fig. 1, the conventional rotary engine structure includes an engine housing, a rotor rotating in the engine housing, and a combustion chamber provided on the engine housing; in order to increase the lubricating effect between the rotor and the engine housing, a lubricating groove for containing lubricating oil is usually arranged on the engine housing, and a roller coating shaft is arranged in the lubricating groove; thus, when the housing of the rotor touches the roller coating shaft, the roller coating shaft can coat the lubricating oil in the lubricating groove on the housing of the rotor.
However, there is a problem in that when the tail end of the bucket slot passes over the roll coating shaft, the bucket slot comes into contact with the roll coating shaft, so that some lubricating oil is applied to the bucket slot. When too much lubricant is accumulated in the bucket slot, the lubricant in the bucket slot may cause some cushioning effect on the pressure released by the combustion chamber, reducing the efficiency of the rotary engine in converting chemical energy into kinetic energy.
Disclosure of Invention
The object of the present invention is to provide a rotary engine capable of avoiding excessive accumulation of lubricating oil in a bucket groove and avoiding reduction in the conversion efficiency of the engine.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a rotary engine comprises an engine housing, a rotor and a combustion chamber, wherein a bucket groove is arranged on the rotor; a lubricating groove for storing lubricating oil is formed in the inner wall of the engine shell, and a guide rail is arranged on the side wall of the lubricating groove; a roller coating shaft is further arranged in the lubricating groove, sliding blocks are arranged at two ends of the roller coating shaft and clamped in the guide rail, and a return spring is further arranged between the sliding blocks and the bottom of the guide rail; the inner wall of the engine shell is also provided with an elastic switch, the elastic switch is in linkage connection with the roller coating shaft, and the elastic switch is positioned at the rear side of the lubricating groove in the rotating direction of the rotor; when the lubricating groove is opposite to the bucket groove, the elastic switch is ejected out and drives the roller coating shaft to be embedded in the lubricating groove; when the lubrication slot is not directly opposite the bucket slot, the resilient switch is compressed by the rotor and the resilient switch drives the roller coating shaft out of the lubrication slot.
As a specific embodiment, a transmission connecting rod component is arranged between the elastic switch and the roller coating shaft.
The transmission connecting rod assembly comprises a connecting block fixed on the elastic switch, a fixing pin fixed on the engine shell and a transmission connecting rod sleeved on the fixing pin, and the transmission connecting rod is connected with the connecting block and the roll coating shaft respectively.
As a specific example, the height at which the resilient switch springs out of the inner wall of the engine housing is no greater than the minimum of the bucket slot depth.
Compared with the prior art, the invention has the following technical effects:
the rotor engine of the invention is characterized in that the elastic switch is arranged on the engine shell and is positioned at the rear end of the lubricating groove in the rotating direction of the rotor, and only when the lubricating groove is not right opposite to the bucket groove on the rotor, the elastic switch is compressed by being extruded by the rotor, so that the rolling coating shaft linked with the elastic switch protrudes out of the lubricating groove and rotates in the contact with the rotor, and the lubricating oil in the lubricating groove is coated on the rotor.
For a better understanding and practice, the invention is described in detail below with reference to the accompanying drawings.
