Description
Technical field
The utility model relates to the drive technology field, is specifically a kind of two-to-one direction changing rotary gearing device.
Background technique
It is a kind of important mechanical motion that the shake double-direction turning movement input becomes unidirectional rotary motion output, in the actual production life, above-mentioned conversion demand extensively exists, therefore how to design a kind of good rotary actuator and realize that this conversion is the direction that the Machine Design personnel make great efforts always, and that at present shake double-direction turning movement input becomes the rotary actuator structure that unidirectional rotary motion output adopts is comparatively complicated, transmission progression is more, is unfavorable for improving transmission efficiency and reduces production costs.
The model utility content
The technical problems to be solved in the utility model is, a kind of simple in structure, transmission efficiency is high, cost of production is low two-to-one direction changing rotary gearing device is provided.
The technical solution of the utility model is, the utility model two-to-one direction changing rotary gearing device, it comprises the first rotating shaft, the second rotating shaft and the 3rd rotating shaft that is parallel to each other, the first rotating shaft is provided with the input gear of just contrary Double-directional rotary, the second rotating shaft is provided with the first output gear, the first ratchet, and the 3rd rotating shaft is provided with the second output gear, the second ratchet; The first ratchet comprises the first outer ring and the first inner ring, and the second ratchet comprises the second outer ring and the second inner ring, oppositely dallies each other all be used to promoting inner ring one-way rotation separately in each outer ring; The first inner ring is fixedly connected with the second rotating shaft, and the second inner ring is fixedly connected with the 3rd rotating shaft; Sequentially mesh described input gear, the first outer ring, the second outer ring.
The utility model working principle is, the direction that the definition outer ring is used for promotion inner ring one-way rotation is positive veer, when the input gear forward, input gear drives the first outer ring counter-rotating, and the first outer ring and the first inner ring dally each other, the first outer ring drives the second outer ring forward, the second outer ring drives the second inner ring forward, and the second inner ring drives the 3rd rotating shaft forward, and the 3rd rotating shaft drives the second output gear forward output, at this moment, the second ratchet plays the effect of output torque; When the input gear counter-rotating, input gear drives the first outer ring forward, the second outer ring counter-rotating, the second outer ring and the second inner ring dally each other, the first outer ring drives the first inner ring forward, and the first inner ring drives the second rotating shaft forward, and the second rotating shaft drives the second output gear forward output, at this moment, the first ratchet plays the effect of output torque; Like this, the clockwise and anticlockwise of input gear is converted to forward output by the second ratchet and the first ratchet respectively, thereby realizes that the shake double-direction turning movement input becomes the purpose of unidirectional rotary motion output; Be reverse directions when defining the outer ring for the direction that promotes the inner ring one-way rotation, principle is the same.
After adopting said structure, the utility model compared with prior art, have the following advantages: the characteristics of the utility model two-to-one direction changing rotary gearing device have been to utilize the characteristics of ratchet, with the clockwise and anticlockwise of input gear all for unidirectional output, not only simple in structure, transmission efficiency is high, cost is low, and the clockwise and anticlockwise of input gear has all obtained utilization, makes the utility model comparatively advanced and practical.
As improvement, described the first output gear, the second output gear are sprocket wheel, and like this, structure is comparatively simple, just unidirectional movement reliably can be exported by chain.
As improvement, described the first output gear is positioned at first ratchet the right, and described the second output gear is positioned at the second ratchet left side, like this, can mutually not interfere between the first output gear, the second output gear, has improved the reliability and stability of structure.
