按，在目前用於傳遞動力與運動的機構中，減速機的應用範圍相當廣泛，常見的減速機有齒輪減速機(Gear reducer)、蝸桿減速機(Worm Wheel reducer)、行星減速機(Planetary gears)等，此些減速機皆是應用齒輪或是齒輪與蝸桿，結構複雜且維修不易，使用成本較高。 According to the current mechanism for transmitting power and motion, the range of applications of the reducer is quite wide. Common reducers include Gear reducer, Worm Wheel reducer, and Planetary gears. ), etc., these reducers are applied gears or gears and worms, the structure is complex and maintenance is not easy, and the use cost is high.
本發明之主要目的乃在於，利用螺紋轉換速度，進而簡化減速機構，方便維修以及降低使用成本。 The main object of the present invention is to utilize the thread conversion speed, thereby simplifying the speed reduction mechanism, facilitating maintenance and reducing the cost of use.
為達上述目的，本發明之減速機構係設置有基座組、傳動桿、位移座以及傳動輪，基座組設置有基座，傳動桿係樞接於基座，且傳動桿表面設置有第一外螺紋，而位移座內設置有第一內螺紋，表面設置有第二外螺紋，第二外螺紋之導程係大於第一內螺紋之導程，且第一內螺紋螺合於傳動桿第一外螺紋，而傳動輪具有第二內螺紋，第二內螺紋係螺合於位移座之第二外螺紋。 In order to achieve the above object, the speed reduction mechanism of the present invention is provided with a base group, a transmission rod, a displacement seat and a transmission wheel. The base group is provided with a base, the transmission rod is pivotally connected to the base, and the surface of the transmission rod is provided with a An external thread, wherein the displacement seat is provided with a first internal thread, the surface is provided with a second external thread, the lead of the second external thread is greater than the lead of the first internal thread, and the first internal thread is screwed to the transmission rod The first external thread has a second internal thread, and the second internal thread is screwed to the second external thread of the displacement seat.
藉上，當傳動桿轉動時，傳動桿之第一外螺紋會推動位移座之第一內螺紋，使位移座於傳動桿上位移，於位移座移動之同時，位移座之第二外螺紋會推動傳動輪之第二內螺紋，俾使傳動輪轉動，且因第二外螺紋之導程大於第一內螺紋之導程，使傳動輪轉 動速率低於傳動桿。 By the way, when the transmission rod rotates, the first external thread of the transmission rod pushes the first internal thread of the displacement seat, so that the displacement seat is displaced on the transmission rod, and the second external thread of the displacement seat is moved while the displacement seat moves. Pushing the second internal thread of the transmission wheel to rotate the transmission wheel, and the lead of the second external thread is larger than the lead of the first internal thread The speed is lower than the drive rod.

請參閱第一圖至第三圖所示，由圖中可清楚看出，本發明係設置有基座組1、傳動桿2、位移座3以及傳動輪4，其中：該基座組1設置有基座11，以及基座11內之限位件12與軸承13，且限位件12為複數設置。 Referring to the first to third figures, it is clear from the figure that the present invention is provided with a base set 1, a transmission rod 2, a displacement base 3 and a transmission wheel 4, wherein: the base set 1 is provided There is a base 11, and a limiting member 12 and a bearing 13 in the base 11, and the limiting member 12 is provided in plural.
該傳動桿2係樞接於基座組1之基座11，且傳動桿2與基座組1之限位件12呈平行狀，並於傳動桿2表面設置有第一外螺紋21。 The transmission rod 2 is pivotally connected to the base 11 of the base set 1 , and the transmission rod 2 is parallel with the limiting member 12 of the base set 1 , and a first external thread 21 is disposed on the surface of the transmission rod 2 .
該位移座3內設置有第一內螺紋31，以及第一內螺紋31一側之限位孔32，第一內螺紋31與限位孔32係貫穿於位移座3二側表面，且限位孔32為複數設置，而位移座3表面設置有第二外螺紋33，第二外螺紋33之導程係大於第一內螺紋31之導程，並使第一內螺紋31係螺合於傳動桿2之第一外螺紋21，而限位孔32套設於基座組1之限位件12。 The first internal thread 31 and the limiting hole 32 of the first internal thread 31 are disposed in the displacement seat 3, and the first internal thread 31 and the limiting hole 32 are penetrated through the two sides of the displacement seat 3, and the limit is limited. The hole 32 is provided in plural, and the surface of the displacement seat 3 is provided with a second external thread 33. The lead of the second external thread 33 is larger than the lead of the first internal thread 31, and the first internal thread 31 is screwed to the transmission. The first external thread 21 of the rod 2 is disposed on the limiting member 12 of the base set 1 .
該傳動輪4具有第二內螺紋41，第二內螺紋41係螺合於位移座3之第二外螺紋33，且傳動輪4係受基座組1之軸承13承托定位。 The transmission wheel 4 has a second internal thread 41. The second internal thread 41 is screwed to the second external thread 33 of the displacement seat 3, and the transmission wheel 4 is supported by the bearing 13 of the base set 1.
請參閱第四圖所示，由圖中可清楚看出，由於基座組1之軸承13限制了傳動輪4位移，讓傳動輪4僅能依軸承13樞轉，且基座組1之限位件12限制了位移座3僅能橫向位移無法樞轉， 故傳動桿2於轉動時，傳動桿2之第一外螺紋21會推動位移座3之第一內螺紋31，使位移座3於傳動桿2上位移，而於位移座3移動之同時，第二外螺紋33會推動傳動輪4之第二內螺紋41，俾使傳動輪4依軸承13樞轉，藉由第二外螺紋33之導程係大於第一內螺紋31之導程，使傳動輪4轉動速率低於傳動桿2，以達到減速之目的。 Referring to the fourth figure, it can be clearly seen from the figure that since the bearing 13 of the base group 1 limits the displacement of the transmission wheel 4, the transmission wheel 4 can only be pivoted by the bearing 13, and the limit of the base group 1 is limited. The position member 12 limits that the displacement seat 3 can only be pivoted without lateral displacement. Therefore, when the transmission rod 2 rotates, the first external thread 21 of the transmission rod 2 pushes the first internal thread 31 of the displacement seat 3, so that the displacement seat 3 is displaced on the transmission rod 2, and while the displacement seat 3 moves, The second external thread 33 pushes the second internal thread 41 of the transmission wheel 4, so that the transmission wheel 4 pivots according to the bearing 13, and the lead of the second external thread 33 is larger than the lead of the first internal thread 31, so that the transmission The rotation speed of the wheel 4 is lower than that of the transmission rod 2 for the purpose of deceleration.
是以，本發明為可解決習知之問題與缺失，其關鍵技術在於，本發明利用限制位移座3僅能於傳動桿2上橫向位移，並於位移座3上設置不同導程之第一內螺紋31與第二外螺紋33，並讓第一內螺紋31螺合於傳動桿2之第一外螺紋21，以及第二外螺紋33螺合於傳動輪4之第二內螺紋41，使傳動桿2帶動傳動輪4轉動時，產生不同的轉動速率，以達到減速之目的，並可簡化減速機構，方便維修且降低使用成本。 Therefore, the present invention solves the conventional problems and lacks. The key technology is that the present invention utilizes the limit displacement seat 3 to be laterally displaced only on the transmission rod 2, and the first inside of the displacement lead 3 is provided with different leads. a thread 31 and a second external thread 33, and the first internal thread 31 is screwed to the first external thread 21 of the transmission rod 2, and the second external thread 33 is screwed to the second internal thread 41 of the transmission wheel 4 to drive When the rod 2 drives the transmission wheel 4 to rotate, different rotation speeds are generated to achieve the purpose of deceleration, and the speed reduction mechanism can be simplified, the maintenance is convenient, and the use cost is reduced.
