Abstract

The utility model discloses a labor-saving transmission mechanism. A trough-shaped bracket serves as a basal body; one end of the bracket is provided with a driving shaft which can rotate around the bracket; a cam which can synchronously rotate along with the driving shaft is fixed on the driving shaft; the other end of the bracket is provided with a driven shaft which can rotate around the bracket; a driven gear is fixed on the driven shaft; a transmission lever is arranged; a unidirectionally rotating driving gear which is engaged with the driven gear is fixed on one end of the lever; a supporting shaft which passes through the lever and serves as the fulcrum of the lever is fixed on one end, ,which is close to the driving gear, of the bracket; the other end of the lever is transmissively engaged with or disengaged from the cam; and the cam can rotate to drive the lever to move up and down. Since the utility model utilizes the leverage theory and the supporting shaft serves as the fulcrum, if the length of the part of the lever at the side of the driving shaft is far larger than the length of the part of the lever at the side of the driven shaft, the force received by the driven shaft is far larger than the force applied on the driving shaft, so the purpose of labor-saving transmission can be realized.

Description

But a kind of labour-saving driving mechanism
Technical field:
But the utility model relates to a kind of labour-saving driving mechanism.
Background technique:
The following kind of drive of the general employing of traditional driving mechanism, chain transmission, gear transmission, bent axle transmission etc., what for example bicycle adopted is exactly chain transmission mode, ride the driving gear that is that is driven, flywheel on the trailing wheel is a driven gear, both can change rotating speed by the size that changes between active and the driven gear, but not have the labour-saving function by chain transmission; Gear transmission is the most frequently used kind of drive, be widely used in lathe, drilling machine, automobile, Hoisting Machinery etc., gear transmission is to mesh by the rotation between the gear to realize transmission, equally, also the size that can change between the gear changes rotating speed, or adopt umbrella gear to change transmission direction, but there is not the labour-saving function yet, in sum, driving mechanisms such as chain transmission commonly used at present, gear transmission, bent axle transmission all do not have the labour-saving function, and inventing a kind of labour-saving driving mechanism promptly is to benefit the society, promote the well-being of mankind.
The model utility content:
For overcoming the defective of prior art, but the purpose of this utility model is to provide a kind of labour-saving driving mechanism.
The utility model technical solution problem adopts following technological scheme:
But a kind of labour-saving driving mechanism, with the fluted body support is matrix, end setting at support can be around the driving shaft of support rotation, set firmly the cam that can rotate synchronously with driving shaft on the driving shaft, the other end setting at support can be around the driven shaft of support rotation, be installed with driven gear on the driven shaft, one transmission levers is set, one end of lever is installed with the driving gear of the unidirectional rotation of meshing with driven gear, on support, set firmly one and pass lever and as the back shaft of balance pivot near an end of driving gear, the other end of lever and cam clutch transmission, cam rotation drives lever and moves up and down.
Structural feature of the present utility model also is:
Card at described cam is provided with axially extended boss, and lever is installed with hook, described boss and the hook clutch transmission of arc near this end of cam.
Described cam is a plurality of being set up in parallel, correspondingly, and the driving gear on described lever and the lever, and the driven gear on the driven shaft also is a plurality of being set up in parallel.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model is by the rotation of driving shaft, cam driven lever on the driving shaft moves up and down, the driving gear of the lever the other end also is that fulcrum moves up and down with the back shaft, driven gear engagement on driving gear and the driven shaft also drives the driven shaft rotation, according to lever principle, with the back shaft is fulcrum, if the lever length of driving shaft one side is much larger than the lever length of driven shaft one side, then in the power that obtains on the driven shaft just much larger than the power that on driving shaft, applies, therefore can reach the purpose of laborsaving transmission.
2, cam of the present utility model, lever, driving gear and driven gear all are a plurality of being set up in parallel, and cooperating separately, strength can be evenly distributed, and can increase the stability of whole driving mechanism operation.
Description of drawings:
Fig. 1 is a perspective view of the present utility model.
Fig. 2 is a plan view of the present utility model, the support of anticipating out not shown in the figures.
Fig. 3 is a plan view of the present utility model.
Number in the figure: 1, support, 2, driving shaft, 3, cam, 4, boss, 5, driven shaft, 6, driven gear, 7, lever, 8, driving gear, 9, back shaft, 10, hook.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment:
Embodiment: referring to Fig. 1, Fig. 2, but present embodiment labour-saving driving mechanism, with fluted body support 1 is matrix, end setting at support can be around the driving shaft 2 of support rotation, set firmly the cam 3 that can rotate synchronously with driving shaft on the driving shaft, the card of cam is provided with axially extended boss 4, the other end setting at support can be around the driven shaft 5 of support rotation, be installed with driven gear 6 on the driven shaft, in order between driving gear and driven gear, to realize transmission, one transmission levers is set, one end of lever 7 is installed with the driving gear 8 with driven gear 6 engagements, driving gear 8 is a ratchet, and its axle is fixedlyed connected with lever, and an end of close driving gear sets firmly one and passes lever and as the back shaft 9 of balance pivot on support, the two ends of back shaft connect firmly on support, lever can be done seesaw type motion around back shaft, sets firmly the hook of an arc, boss and hook clutch transmission during cam rotation at lever near this end of cam.
Embodiment 2: referring to Fig. 3, present embodiment is with embodiment 1, different is, cam 1 is a plurality of being set up in parallel, correspondingly, the driving gear 8 on lever 7 and the lever, and the driven gear on the driven shaft 6 also is a plurality of being set up in parallel, make the strength of transmission be evenly distributed like this, therefore can increase the stability of whole driving mechanism operation by several levers.
During concrete enforcement, driving shaft 2 is by motor, motor or manpower drive and are rotated counterclockwise, cam 3 rotations simultaneously, when boss 4 combines with the inner arc surface of hook 10, boss is carried lever 7 and is moved upward, the driving gear 8 of the lever the other end moves downward simultaneously, driven gear and driving gear engagement are rotated, because driven gear is fixedlyed connected with driven shaft, thus driven shaft also rotate, when the inner arc surface of boss 4 and hook 10 breaks away from, because action of gravity, this end of the hook of lever falls, and the other end of lever lifts, and driving gear is a ratchet, this moment, driving gear rotated, be back to initial state, finish course of action next time, so move in circles and carry out transmission.According to lever principle, be fulcrum with the back shaft, if the length of close this end of driving shaft of lever is the several times near that end length of driven shaft, just be the several times of the power that applies on driving shaft then in the power that obtains on the driven shaft, therefore can reach the labour-saving purpose.
