Abstract
A kind of heaver actuating device, its feature is that it has a mechanism of bi-connecting rod, which is composed of the heaver and two parallel foot-connecting bars, there has the gear rack which floated with the mechanism of bi-connecting rod, and adapting with the orient gear which muff coupled on the power output shaft, there are tow sets of the heavers and the foot-connecting bars at lest, and compose two sets of the mechanisms of bi-connecting rod. Its advantage is that it can adjust the required length of the tension arm optionally, the mechanisms of bi-connecting rod controlled that the motion mode of the apply of the heaver must be the parallel motion, no matter how long the tension arm of the heaver prolonged, the required distance of the apply work always unchangeable; the two parallels do the apply work take turns and forming the great and successional impetus by making the input power through the great drive ratio, it is energy saving, labor saving.
Description
Technical field
The present invention relates to a kind of drive unit, particularly a kind of lever driving device.
Background technique
Lever law is the mechanical general knowledge that people know, the concrete manifestation that at present lever is applied to mechanical Continuous Drive or transmission aspect is to drive gearwheel or small belt pulley band big belt pulley etc. with small gear, but because lever arm of force rotates around fulcrum, the arm of force is long more, the required swing space of its arm of force is just big more, and the power of its output can't form bigger and successional work done power by bigger velocity ratio with input power with regard to restricted when the swing space is restricted.
Summary of the invention
Purpose of the present invention just provide a kind of can the required arm of force length of regulated at will lever, no matter how long the arm of force of lever prolongs, the needed distance of lever work done is constant all the time, and can realize input power is formed bigger and successional work done power by bigger velocity ratio, lever driving device simple in structure, that mechanical efficiency is higher.
Solution of the present invention is such: have two fulcrum connecting rods that are hinged on the end formation parallel four-bar linkage of lever, the other end of lever stretches out, on fulcrum connecting rod and the lever section of stretching out formation swing arm, be hinged with tooth bar, tooth bar and the oriental toothed gear engagement that is socketed on the pto.
Lever, fulcrum connecting rod have two groups at least, constitute two groups of parallel four-bar linkages, every group of hinged tooth bar and the gear engagement that is socketed in separately on the pto, two groups of parallel four-bar linkages have the interlock returning device respectively, adopt two groups of parallel four-bar linkages can be easily outputting power continuously.
Working principle of the present invention is exactly to utilize the external force that acts on the lever, presses lever and moves downward, and after by lever power being amplified, exerts pressure to tooth bar, drives axle rotation outputting power through oriental toothed gear.
Advantage of the present invention is can the required suitable arm of force length of regulated at will lever, and the motion mode that utilizes parallel four-bar linkage to control the lever work done is parallel moving, and no matter how long the arm of force of lever prolongs, and the needed distance of lever work done is constant all the time; Move work done and just can realize input power is formed bigger and successional work done power by bigger velocity ratio if adopt at least two levers to take turns down tilt under external force, energy-conservation, laborsaving.
Description of drawings
Accompanying drawing is embodiments of the invention.
Accompanying drawing 1 is a structural representation of the present invention.
Accompanying drawing 2 the present invention have the structural representation of interlock return mechanism.
The plan view of accompanying drawing 3 accompanying drawings 2.
Embodiment
Have two fulcrum connecting rods (5,6) that are hinged on the end formation parallel four-bar linkage of lever 1, the other end of lever 1 stretches out, on fulcrum connecting rod 5 and lever 1 section of stretching out formation swing arm, be hinged with tooth bar 2, tooth bar 2 and oriental toothed gear 3 engagements that are socketed on the pto 4, as shown in Figure 1, this kind structure can not self-return because lever 1 does not have returning device, can not drive the pto outputting power during return.
Described interlock returning device is to be hinged with the two ends that 7, two pull bars 7 of pull bar are hinged on fork 8 respectively on two levers 1 respectively.In the accompanying drawing 2, described pull bar 7 is to be hinged on the end that lever 1 is connected with fulcrum connecting rod (5,6) respectively.
Described tooth bar 2 is the hinged places that are hinged on lever 1 and fulcrum connecting rod 5, shown in accompanying drawing (1,2).In addition, described tooth bar 2 can be to be hinged on the lever 1.Described tooth bar 2 can also be to be hinged on the fulcrum connecting rod 5.
Structure shown in the accompanying drawing 2 is when work, act on the section of stretching out of lever 1 downwards by outer power, thereby can arbitrarily transfer the long lever arm of force to needed appropriate length, with obtain maximum laborsaving, economize can purpose, driving lever 1 downward translation, the motion of lever 1 drives the tooth bar 2 that is hinged with it, and band changes oriental toothed gear and rotates, the rotation of gear band moving axis can output power.When it has interlock during return mechanism, the motion of one group of lever drives another group lever return, and under external force, lever 1 takes turns parallel mobile work done, drives axle and rotates continuously, and power is passed continuously.
