Description

Reciprocally swinging transmission and application

The present invention relates to a kind of transmission device and application thereof that swing power can be converted into rotating power

The swing power switching device of using generally all is a transmission rod-type mechanism at present, as bicycle, treadle type sewing machine, it is characterized in that carrying out power-converting with the drive link mode, and be the power-converting between the parallel axes, high speed performance is better, but low-speed performance is relatively poor, as unsatisfactory in effect aspect the conversion of Wave power, patent gazette (application number: 91208218.6) once disclosed a kind of tricycle reciprocating drive unit, it is that two flywheels are installed on rear axle side by side, two ends on the axis parallel with rear axle are separately installed with fork and pedal, two groups of each self-reversal connection chain wheels of chain, spring, fork and immovable point drag left side sprocket wheel acting when scrunching pedal, right side sprocket wheel counter-rotating, unclamp pedal, then drag right side sprocket wheel acting, the counter-rotating of left side sprocket wheel by spring, subject matter is, when scrunching pedal, not only to drag the sprocket wheel acting, also to drag spring simultaneously, so just increase and scrunch dynamics, the difficulty that has increased starting and driven a vehicle.

The objective of the invention is to improve the prior art deficiency, provide the compound transmission of a kind of cable and chain and by the complete cable driving mechanism of its evolution,---chain, line---transmission combination between line that makes line can be used for solving the transmission conversion between unparallel shaft.

The present invention seeks to realize like this:

Fig. 1, Fig. 2, Fig. 3 are structural representations of the present invention;

Fig. 4 is the ratchet view that becomes appearance structure;

Fig. 5 is the basic embodiment of totally-enclosed tricycle;

Fig. 6 is the basic embodiment of Wave power conversion equipment;

Details are as follows below in conjunction with view:

See Fig. 1, two sprocket wheel A are installed on running shaft, A ｀, two chain L on the sprocket wheel, the top of L ｀ (being pilled-in selvedge) respectively with bearer cable B, B ｀ links to each other, hawser B, the other end of B ｀ can connect the two ends C of fork S, C ｀, chain L, the bottom of L ｀ (being the slack list) connect guiding hawser E and with leading block F solderless wrapped connection, thereby make fork S, sprocket wheel A, A ｀, and leading block F is by by with hawser B, B ｀, Transmitted chains L, the drive line that L ｀ and guide cable E form organically is connected in series, form a double-action mechanism, its working principle is: when dragging fork C end, stressed cable B and Transmitted chains L are dragged, drive sprocket wheel A rotary driving axle outputting power, Transmitted chains L drags the guide cable E pile warp leading block F that joins with it simultaneously and drags Transmitted chains L ｀, drive sprocket wheel A ｀ reversing, and drive hawser B ｀ retreats; On the contrary, when dragging fork C ｀ end, whole process is with above-mentioned opposite, sprocket wheel A ｀ is dragged and driven rotary axle outputting power by Transmitted chains L ｀, therefore, because the unidirectional torque function of sprocket wheel, when the fork S that links to each other with stressed cable B, B ｀ swings continuously, a stressed work done of sprocket wheel is always arranged, thereby finished the conversion that transfers to merit by swing work done mutarotation; Fork S also can be substituted by other power bearer cable B, B ｀ are back and forth dragged.

Fig. 2 has shown the power-converting schematic representation that two leading block F, F ｀ are housed, and wherein escapement H has substituted fork S, and can be fixed on the escapement at the G hawser of naming a person for a particular job.

If above-mentioned running shaft adopts semiaxis, then this mechanism also can to about two semiaxis carry out driven.

Said apparatus can change swaying direction by installing leading block additional, sees Fig. 3.

Sprocket wheel in the said apparatus then can be realized the reversing of running shaft if use double rolling key clutch to substitute.

The maximum characteristics of said apparatus are by utilizing the combination of cable, Transmitted chains and pulley, good solution chain-driven can only carry out transmission between the parallel axes, and can not carry out the transmission problem of other form, and the structure separate room, easy to manufacture.

Because the active part of this mechanism is for back and forth dragging, the journey of the hawser that drags was long certain when fork was expired width of cloth swing at every turn, therefore, as long as the length of Transmitted chains L, L ｀ satisfies the swing that fork drags.

Fig. 4 has shown a kind of evolution, can remove the ratchet mechanism of chain, its internal structure is identical with ratchet, external structure is a pulley profile, it is the race that the gear teeth of sprocket wheel change pulley into, because this mechanism is made up of ratchet and pulley two-part, and possesses unidirectional torque function again, hereinafter to be referred as " sour jujube pulley ", hawser is wrapped in some circles on the sour jujube pulley, and the hawser of intermediate portion is fixed, and G is fixing dead for knot, and as long as the length of both sides institute pitch of the laps number is the swing that is dragged when swinging greater than fork (or escapement), like this, the combination transmission of above-mentioned hawser and chain just can develop into pure hawser and drag, and its advantage is that the transmission accuracy requirement is low, and structure is simpler; Its hawser is chosen as wirerope or belt.

Above-mentioned ratchet and sour jujube pulley mechanism all can be substituted by suitable step mechanism such as magnetic clutch etc.

This change swing energy has purposes widely into the technology of rotating energy, for example: utilize this technology to can be made into the reciprocally swinging bicycle, swinging body-building device and Wave power conversion equipment (containing wave-activated power generation, Wave power ship etc.), this technology can be applicable to any be fit to the swing energy of this device and the conversion of swing mode.

The circumference revolution space is very big immediately stepping on step for the tricycle of using at present, when pedal goes to the lower end almost near ground, therefore, it is very difficult to make the totally enclosed type tricycle that can keep out wind and rain, if raise wheel disc, then chain and seat will be elevated simultaneously, thereby it is higher to be directed at center of gravity, and driving is unstable; Utilize this technology can be easy to vertical circumference with bicycle and scrunch and change horizontal level into and back and forth scrunch, thereby lower the center of gravity, realize the totally-enclosed of tricycle, see Fig. 5.

From Fig. 1, Fig. 2, Fig. 3, as can be seen,, can on the hawser of its connection, install leading block additional and change transmission direction and push-pull fashion, and expansion tightening wheel can be installed adjust the tensioner degree no matter in the pilled-in selvedge or the slack list of chain.

This driving mechanism also can be used on Wave power conversion aspect, Fig. 6 has shown Wave power conversion schematic representation (wherein containing the swing mechanism that uses in parallel), the several oscillating actuation mechanism is housed on power platform 1, at escapement one end (or two ends) floating drum 2 is housed, floating drum is fluctuated by wave action, drive escapement and back and forth drag hawser, make sour jujube pulley 3 alternately export unidirectional torque and give transmission shaft 4, its rotating power becomes useful power output after speed change gear 5 is integrated; The platform of this Wave power conversion equipment can substitute with retired ship, thereby can reduce cost, and design is oversimplified more, can be applicable on the coastal thousands of island of China, and can be exported to external.
