But no matter how precise the overrunning clutch is, there will always be a loss in travel, not to mention the engine speed, which can reach thousands or even tens of thousands per minute, so any excellent overrunning clutch will have a long service life.

Embodiment Construction

[0033] Such as figure 1 , the half-circular gear (2) installed on the rotating shaft (1) is a gear composed of a part circular gear and a part non-circular gear: the teeth of the part circular gear are the teeth of section AB in the figure, and it is the same as The teeth of ordinary circular gears are arranged in the same way, that is, the distance from each tooth to point D of the gear's rotation center (axis center) is constant. This constant distance is the constant radius of the semicircular gear. That is, the linear distance from D to B or from D to A in the figure; the gear teeth of the non-circular part are the gear teeth of DA and BD two sections, since D is the rotation center of the semicircular gear (2), the A gear tooth with a gear radius of zero. Therefore, the gear teeth of the DA segment, the gear radius from D to A, gradually increases from zero until it is equal to the constant radius, while the gear teeth of the BD segment, the gear radius from B to D, is c...

Abstract

The invention relates to a gear rack reciprocating motion mechanism and an engine thereof and designs a minimum semicircular gear, semidiameter of which is zero. Utilizing chronotropic action of non-circular gear in the semicircular rack, process of gear movement is from acceleration from standstill, speed reduction to motionless, therefore impact of the gear by the rack is eliminated, and continuous rotation of the gear and reciprocating shockless shifting of the rack are realized. In addition, the invention can reciprocating move in different types to improve mechanical efficiency. For example, reciprocating motion of fast forward and slow backward can prolong admission period and working time of the engine. Compression time is shortened, and exhaust can adjust a valve to keep in good order. Power per liter of the engine is increased, low speed property is improved, use ratio is improved largely and energy is saved.

Description

1. Technical field: [0001] The present invention relates to a reciprocating mechanism, especially related to the reciprocating mechanism of an engine. 2. Background technology: [0002] Since the rotary engine could not be solved due to the sealing problem, the engine has almost become a piston type. However, due to structural reasons, the mechanical efficiency of the crank-link mechanism that pushes the piston to reciprocate is only about 0.8. For this reason, there have been many engine patents with a rack and pinion with higher transmission efficiency as the reciprocating mechanism. However, to make the stationary rack move or the moving rack to stop, there must be a speed change process of acceleration or deceleration, which cannot be matched with the gear rotating at a uniform speed, which will produce a large impact and eventually be difficult to operate. Although in these patents, some also have gears to follow the rack and rack to reciprocate together, and then use...
