Abstract
The utility model discloses a lever transmission mechanism. When a driving rotating rod is rotated around the circumference, a lever 3 is swung from top to bottom and is moved in a slip tube 4 in a reciprocating way. The lever 3 can also cause a driven rotating rod 4 to be rotated, and the driven rotating rod 4 is also moved in a slip tube 6 in a reciprocating way. Therefore, the power of a shaft 7 is transferred to a shaft 8. One lever in the lever gearing can play two functions of the lever and a side rod. The utility model has the advantages of no dead center, continuous circumferential rotation, and labor saving. Besides, the production efficiency can be improved. The utilization can be widely applied to the field of mechanical transmission.
Description
The utility model relates to a kind of mechanical lever driving mechanism.
The used transmission of available dynamic equipment has: band transmission, chain-driven, gear transmission, connecting rod transmission and lever transmission etc.Connecting rod has the dead point in the transmission process, the garden revolution, and mechanisms such as flywheel must be installed.Lever will become the garden revolution swinging up and down in transmission process, mechanisms such as sour jujube ratchet must be installed, and just can carry out the garden revolution.
The purpose of this utility model provides a kind of lever transmission mechanism, and it can not only surpass the gearing of lever, also can play the gearing of connecting rod simultaneously.
The purpose of this utility model is achieved in that
Lever is installed in the slip pipe of fulcrum in mode movingly, and two ends are respectively in movingly mode, is installed on the axle of initiatively bull stick and passive bull stick end points.Initiatively the other end of bull stick is installed on the transmission shaft, the other end of passive bull stick is installed in the slip pipe on the transmission shaft or in the slip pipe of lever end points in the mode that cooperates, when the active bull stick rotates, slidably reciprocate on the flexible or fixing rod in the fulcrum slip pipe of lever, and swing up and down, power is passed to passive bull stick, and passive bull stick has in the slip pipe of axle point or in the slip pipe of lever end points and slides.
After adopting above-mentioned lever transmission mechanism, because a lever has just played the effect of connecting rod and lever, and rotate no dead point continuously and mechanisms such as flywheel and ratchet need be installed, thereby reduced manufacture cost, improved transmission performance and reliability, gram can the dead point that exists of connecting rod transmission, the speed change transmission of Keyuan Garden week, by the shift lever fulcrum, can carry out variable force and laborsaving transmission, and also simple in structure.
The concrete structure of model utility is provided by following example and accompanying drawing:
Fig. 1 is the fixed point transmission of lever transmission mechanism
Fig. 2 is the unfixed point transmission of lever transmission mechanism
Among the figure 1, fixing rod 2, bull stick initiatively
3, lever 4, slip pipe
5, passive bull stick 6, slip pipe
7, axle 8, axle
Lever in Fig. 1 (3) is installed in the fulcrum slip pipe (4) in the mode that cooperates, the rotatingshaft of one end on active bull stick (2) end points connects, the other end is installed in mode movingly with the axle (7) be connected active bull stick (2) and fixing rod (1) by the rotatingshaft on transmission rod (5) end points on, and axle (8) slip pipe (6) on passive bull stick (5) and the fixing rod (1) is installed in mode movingly.Fulcrum slip pipe (4) is fixed between two axle points of fixing rod (1).When active bull stick (2) rotated, lever (3) slided in fulcrum slip pipe (4), and was the garden heart with fulcrum slip pipe (4), swing up and down, passive bull stick (5) is rotated, and slide, thereby initiatively the merit of bull stick (2) is passed to by transmission rod (5) at axle (8) slip pipe (6).
Lever in Fig. 2 (3) is fixed on the fulcrum slip pipe (4), and fulcrum slip pipe (4) is installed on the fixing rod (1) in mode movingly.One end of lever (3) is connected with rotatingshaft on bull stick (2) end points initiatively, and the other end and passive bull stick (5) are installed in mode movingly, and the axle (8) on passive bull stick (5) and the fixing rod (1) is installed in mode movingly.When active bull stick (2) rotates, lever (3) and fulcrum slip pipe (4) are gone up at fixing rod (1) together and are slided, lever (3) is the garden heart with fulcrum slip pipe (4), swing up and down, passive bull stick (5) is rotated, and in the slip pipe (6) of lever (3) end points, slide, thereby the merit of main transmission rod (2) is passed to passive bull stick (5).
Claims (1)
1, a kind ofly is used for mechanically operated lever transmission mechanism, it comprises initiatively bull stick, passive bull stick, fixing rod, fulcrum and lever, it is characterized in that: initiatively bull stick 2 connects in an end of lever 3, lever 3 slides in fulcrum slip pipe 4 or slides on fixing rod 1 together with the fulcrum slip pipe, the other end of lever 3 is connected with passive bull stick 5, and passive bull stick 5 slides in axle point slip pipe 6 or slides in the slip pipe 6 of lever 3 end points.
