Abstract
The utility model provides a mechanism for changing linear reciprocating motion into circular uniform motion, which can realize the transform of two motion with simple driving members. The utility model is provided with a gear rack and a gear. Both sides of the gear rack are provided with internal straight-teeth. The gear is engaged with the gear rack, which is provided with half circle of tooth shapes. When the internal straight-teeth of one side are engaged, the internal straight-teeth of the other side are broken away teeth with the gear. Each end of the two internal straight-teeth sections of the gear rack is elastically embedded with an automatic engaging and disengaging gear block. The gear blocks are arranged along an inclined diagonal line. The internal straight-teeth section of the gear rack is at least equal to the section having tooth shapes of the gear. The automatic engaging and disengaging gear block is at least provided with three tooth shapes.
Description
The utility model belongs to motion gear.
Solve the method that straight reciprocating motion becomes garden Zhou Yundong at present, the one, use connecting rod, as piston-engined connecting rod and bent axle, its shortcoming was that upper and lower stop leans on flywheel inertia, the rotating speed inequality, work done is little, and piston and cylinder have the side pressure wearing and tearing; Chinese patent ZL93201421.6 name is called direct-shaft engine, be that the driven gear that utilizes annular rack to replace on the reciprocating sliding d-axis rotates d-axis, though overcome a lot of shortcomings that crankshaft ﹠ connecting brings, but for the alternately engagement and disengaging of tooth bar that guarantees the d-axis both sides, add the coordination control mechanism, this has just increased the weight and the complexity of whole parts.
At the deficiency that above-mentioned prior art exists, the utility model proposes the mechanism that a kind of straight reciprocating motion becomes garden week uniform motion, it just can realize the conversion of two kinds of motions with open-and-shut dirivig member.
The purpose of this utility model reaches with following measure: there be rack frame and gear that is meshed with it and has the half-turn profile of tooth of straight-tooth in the both sides band in this mechanism, when a side straight-tooth of wheel and rack frame meshes, the straight-tooth of opposite side just in time takes off tooth with gear, do not hold each activity to be inlaid with an automatic clutch tooth piece at two internal straight-toothed sections of rack frame, and by the clinodiagonal setting.The internal straight-toothed section of above-mentioned rack frame should equal the arc length section that profile of tooth is arranged on the gear at least, and their profile of tooth preferably adopts zigzag fashion.Have three profiles of tooth above the automatic clutch tooth piece at least.
Be described further below in conjunction with embodiment of the present utility model and accompanying drawing thereof.
Fig. 1 is a stereogram of the present utility model.Fig. 2 is the Facad structure schematic representation.Fig. 3 is the mechanism kinematic schematic representation, and wherein a is depicted as the state of rack frame (1) when moving to top dead center, and b is the state of rack frame (1) when moving to lower dead center.Fig. 4 uses the embodiment's schematic representation that replaces original crankshaft ﹠ connecting in motor for this mechanism, and dotted line partly is to use the crankshaft-link rod that saves after this mechanism, and the volume of cylinder also is reduced to original below 1/3rd.
As shown in the figure, the mechanism that the straight reciprocating motion that the utility model proposes becomes garden week uniform motion is a kind of very simple and practical driving mechanism, it has one or two inboard to be the straight-tooth section, upper/lower terminal is half garden, oval-shaped rack frame (1) in closure forms one, screw (8) and straight reciprocating motion part can be passed through in its top, and be affixed as piston.The half-turn gear (2) that is fixed on the d-axis (4) by axle key (3) is loaded in the ellipse of rack frame rack frame both sides straight-tooth and half-turn gear engagement.Rigging position is: when gear is positioned at the arbitrary end of rack frame, there is the half-turn of tooth should be over against the other end of rack frame, and gear automatic clutch tooth piece (5) engagement that has three teeth of tooth Duan Shangyi end to install with elasticity, the other end then just takes off tooth with internal straight-toothed section.Automatic clutch tooth piece has two, becomes the clinodiagonal setting, and effect is to guarantee to have three teeth to be engaged with smoothly when making rack frame arrive upper and lower stop.Automatic clutch tooth piece is connected with return spring (6) behind and adjusts screw (7).
The foregoing description that the utility model provides, because gear is formed the structure that side engagement opposite side takes off tooth by the internal straight-toothed section of rack frame and the half-turn gear on the d-axis, on even rack frame arrives, lower dead center begins when return, because of gear continues to rotate in the same way, phenomenon that so pause suddenly can not occur or slow down, rotating speed is evenly smooth and easy, be used for substituting existing piston engine connecting bar and crankshaft, can make the motor volume reduce 30%, weight reduces 25%, and power increases 15～30%, and starting rapidly, the piston no side pressure wearing and tearing of moving in cylinder can prolong life-span of motor.
Working principle is as follows: when rack frame moves to top dead center position (shown in a among Fig. 3), the right side tooth of gear is thrown off, the engagement of left side tooth.When rack frame is up, because the left side tooth is engagement, just promotes gear and rotate counterclockwise, because right side tooth and rack frame break away from, and enter anodontia section again, so can not influence the reverse gear motion of rack frame and gear.When arriving lower dead center (shown in Fig. 3 b), three teeth in gear right side enter engagement by the clutch teeth block on rack frame right side, and at this moment the gear left side just in time breaks away from engagement with rack frame.Just in time with above-mentioned opposite, promote gear by the left side engagement and continue to rotate counterclockwise when moving on the rack frame, move in circles, this mechanism is that mechanical energy transfers out by d-axis with the thermal power transfer of motor.
Claims (3)
1, a kind of straight reciprocating motion becomes the mechanism of garden week uniform motion, it is characterized in that: a rack frame (1) and a gear that is engaged with and the half-turn profile of tooth is arranged (2) that straight-tooth in the both sides band is arranged, when a side straight-tooth of wheel and rack frame meshes, the straight-tooth of opposite side just in time takes off tooth with gear, the straight-tooth Duan Weiduan elasticity that is positioned at rack frame two inboards is inlaid with an automatic clutch tooth piece (5), and by the clinodiagonal setting.
2, mechanism according to claim 1 is characterized in that: the either side internal straight-toothed section of rack frame (1) should equal on the gear (2) profile of tooth arc length section arranged at least, and profile of tooth preferably adopts zigzag fashion.
3, mechanism according to claim 1 is characterized in that: have three profiles of tooth above the automatic clutch tooth piece (5) at least.
