Description
本發明係關於一種雙向棘輪結構；更詳細而言，本發明係關於一種動力由主輪輸入時，無論主輪正轉或逆轉，均可由定向齒輪輸出固定轉向動力；反之，若動力由定向齒輪輸入時，無論定向齒輪為正轉或逆轉，亦均可由主輪輸出固定轉向動力之雙向棘輪結構。The present invention relates to a two-way ratchet structure; more particularly, the present invention relates to a type of power input by the main wheel, whether the main wheel is rotating or reversing, the steering gear output can be fixed by the steering gear; When inputting, the two-way ratchet structure of the fixed steering power can be output from the main wheel regardless of whether the directional gear is forward or reverse.
棘輪為一般工業上經常使用之元件，其作用為使得線性往復運動或旋轉運動保持單一方向動力輸出的機械機構，用以防止傳動機構逆轉。The ratchet is an element commonly used in the industry, and functions as a mechanical mechanism that maintains linear reciprocating or rotational motion to maintain a single direction of power output to prevent the transmission mechanism from reversing.

請參考第一圖及第二圖所示，本發明之雙向棘輪結構1，一主輪10，內部具複數環狀槽以容納外環狀棘輪11、內環狀棘輪13及定向齒輪15，並具有主輪軸103及環狀凸起之主輪外緣101、主輪內緣102；複數外層棘爪12，固定於主輪外緣101；複數內層棘爪14，固定於主輪內緣102；一外環狀棘輪11，其外側棘齒111與外層棘爪12連動，內側齒輪112與定向齒輪15連動；一內環狀棘輪13，其內側棘齒131與內層棘爪14連動，外側齒輪132與定向齒輪15連動；複數定向齒輪15，設置於外環狀棘輪11與內環狀棘輪13間，具有定向齒輪軸151，並與棘輪組相互連動。Referring to the first and second figures, the two-way ratchet structure 1 of the present invention has a main wheel 10 having a plurality of annular grooves therein for accommodating the outer annular ratchet 11, the inner annular ratchet 13 and the directional gear 15, and a main wheel outer edge 101 having a main axle 103 and an annular projection, a main wheel inner edge 102; a plurality of outer detents 12 fixed to the outer wheel outer edge 101; a plurality of inner detents 14 fixed to the inner wheel inner edge 102 An outer annular ratchet 11 having an outer ratchet 111 and an outer pawl 12, the inner gear 112 and the directional gear 15 interlocking; an inner annular ratchet 13 having an inner ratchet 131 and an inner pawl 14 interlocking, outer side The gear 132 is interlocked with the directional gear 15; the plurality of directional gears 15 are disposed between the outer annular ratchet 11 and the inner annular ratchet 13, and have an directional gear shaft 151 and are interlocked with the ratchet set.
承上，其中之主輪軸103及定向齒輪軸151均向外延伸，並固定於主輪10以外之物體，亦即主輪軸103及定向齒輪軸151之相對位置固定。The main axle 103 and the directional gear shaft 151 extend outwardly and are fixed to objects other than the main wheel 10, that is, the relative positions of the main axle 103 and the directional gear shaft 151 are fixed.
承上，其中之外環狀棘輪11之過濾方向與內環狀棘輪13之過濾方向相反，亦即外環狀棘輪11與內環狀棘輪13於同時間內僅有一組由棘爪與主輪10連動，另一組處於棘爪滑開而可自由轉動。The filtering direction of the annular ratchet 11 is opposite to the filtering direction of the inner annular ratchet 13, that is, the outer annular ratchet 11 and the inner annular ratchet 13 have only one set of pawls and main wheels at the same time. 10 linkages, the other group is in the pawl slipping open and free to rotate.
請參考第三圖，當本發明之雙向棘輪結構1，由主輪10輸入左旋動力時，外層棘爪12帶動外環狀棘輪11左旋，而內層棘爪14滑開使內環狀棘輪13可自由旋轉，外環狀棘輪11左旋經由其內側齒輪112帶動定向齒輪15左旋。實現主輪10輸入左旋動力時，由定向齒輪15可輸出左旋動力。Referring to the third figure, when the two-way ratchet structure 1 of the present invention inputs left-handed power from the main wheel 10, the outer pawl 12 drives the outer annular ratchet 11 to rotate left, and the inner layer pawl 14 slides open to make the inner annular ratchet 13 Freely rotatable, the outer annular ratchet 11 is left-handed to drive the directional gear 15 to the left by its inner gear 112. When the main wheel 10 is input to the left-handed power, the directional gear 15 can output the left-handed power.
請參考第四圖，反之，當本發明之雙向棘輪結構1，由主輪10輸入右旋動力時，外層棘爪12滑開使外環狀棘輪11可自由旋轉，而內層棘爪14帶動內環狀棘輪13右旋，內環狀棘輪13右旋經由其外側齒輪132帶動定向尺輪15左旋。實現主輪10輸入右旋動力時，由定向齒輪15可輸出左旋動力。Referring to the fourth figure, in contrast, when the two-way ratchet structure 1 of the present invention inputs the right-handed power from the main wheel 10, the outer pawl 12 slides open to allow the outer annular ratchet 11 to freely rotate, and the inner layer pawl 14 drives The inner annular ratchet 13 is right-handed, and the inner annular ratchet 13 is rotated rightward via its outer gear 132 to rotate the directional ruler 15 to the left. When the main wheel 10 inputs the right-handed power, the directional gear 15 can output the left-handed power.
綜上所述，藉由本發明所揭示的雙向棘輪結構1，實現一種無論動力為正向或逆向輸入時，均可將動力過濾並導向為固定方向輸出之機構裝置。In summary, with the bidirectional ratchet structure 1 disclosed in the present invention, a mechanism device capable of filtering and guiding power to a fixed direction output regardless of whether the power is forward or reverse input is realized.
