Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a speed reduction mechanism. [Prior Art] [0002] As an important part of mechanical transmission, the speed reduction mechanism is widely used in robots, automobiles, and other industries. A common reduction mechanism typically uses two intermeshing gears that are different in diameter to achieve deceleration. [0003] The type of speed-extinguishing mechanism includes an outer casing, an inner gear formed in the outer casing, a crankshaft having an eccentric portion disposed in the outer body, and a cycloidal wheel provided with gear teeth disposed on the eccentric portion. The cycloidal wheel is interlocked with the eccentric portion of the crankshaft, and the output is twisted by decelerating the input rotation by the side and the internal gear U#. S, in order to achieve a 33-fold coincidence of the highest, and obtain a smooth output, the cycloidal wheel of the above-mentioned speed reduction mechanism usually forms a tightly-set tooth on the outer peripheral surface of the outer surface of the outer wheel. When the whole body of the mechanism is limited to the limit, the teeth need to be made very small and the distance between the teeth and the circumference of the teeth is also very small. Even the roots of the teeth will have overlapping 千 千 千 :: thus the cycloidal wheel and its The manufacturing of gear teeth is more difficult, the production cost is higher and the structure is more complicated. [Summary of the Invention] In the above, it is necessary to provide a speed-losing mechanism which is simple in structure and low in cost. [0005] A speed reduction mechanism 'includes a transmission assembly and a power material, the transmission assembly includes a propeller, a first follower, a second follower, a first transmission member and a second transmission member, and the power component is connected with the active member The rotary power of the active part is provided. The first transmission member connects the main domain and the first driven member, and drives the first slave driven by the active 099107593 table grass number A0101 page 3 / 18 pages 0992013687- 201132878. When the piece rotates, the second transmission member connects the first follower and the second follower, and drives the second follower to rotate under the driving of the first follower. [0006] The speed reduction mechanism realizes the reduction transmission by connecting the first transmission member of the active member and the first driven member and the second transmission member connecting the first driven member and the second driven member, thereby eliminating the gear The device with complicated structure has simple structure, low production cost and simple structure. In addition, the setting of the two transmission members enables the speed reduction mechanism to realize multi-stage transmission. [Embodiment] Hereinafter, the speed reduction mechanism of the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments. Referring to FIG. 1, a speed reduction mechanism 100 according to an embodiment of the present invention can be applied to a mechanical device such as a robot. The speed reduction mechanism 100 includes a transmission assembly 10, a power unit 30 that provides transmission power for the transmission assembly 10, and a bracket 50 that supports the transmission assembly 10. The transmission assembly 10 includes an active member 11, a first follower 12, a second follower 13, a first transmission member 14, a second transmission member 15, and a fixing member 16. The first driving member 14 is wound around the driving member 11 and the first driven member 12, and the second transmission member 15 is wound around the first driven member 12 and the second driven member 13. The fixing member 16 fixedly connects the end of the first transmission member 14 with the first follower member 12, and the end of the second transmission member 15 is fixedly coupled to the second follower member 13. [0010] The active member 11 is substantially cylindrical and has one end connected to the power component 30. Referring to FIGS. 1 and 2, the first follower 12 includes a driven shaft 121 and a driven wheel 123 formed on the driven shaft 121. The driven shaft 121 is substantially cylindrical. 099107593 Form No. A0101 Page 4 of 18 0992013687-0 201132878 The diameter of the driven shaft 121 is smaller than the diameter of the driven wheel 123. In this embodiment, the number of the driven wheels 123 is two, and each of the driven wheels 123 is provided with a screw 6 and a valley groove 125. The ratio of the diameter of the driven wheel 123 to the diameter of the driving member η is the first stage gear ratio. [0012] Referring to FIG. 1 to FIG. 3, the second follower 13 includes a transmission portion 131, a transmission rod 133 extending from the end of the transmission portion 131, and a through hole extending through the transmission portion 131. 135 and the rotating shaft 137 ^ The transmission portion 131 is substantially a fan-shaped structure, and includes a connecting end 1311, two side walls 1313 extending from the connecting end 1311, and a curved edge 1315 connecting the two side walls 131 3 ... the curved edge 131 5 is curved The receiving slot 1317 is opened in the extending direction. In the embodiment, the number of the receiving slots 1317 is four and substantially parallel. The transmission rod 133 extends from the connecting end 1311 away from the curved edge 1315. The through hole 135 is located between the side wall 1313 and the curved edge 1315. The rotating shaft 137 is partially received in the connecting end 1311. The ratio of the radius of the sector structure of the transmission portion 131 to the radius of the driven shaft 121 of the first follower I? is the second stage transmission ratio. The fan angle of the transmission portion 131 of the second follower 13 is obtained by multiplying the ratio of the number of rotations of the first extension member 12 to the second-stage transmission ratio and multiplying by three hundred and sixty degrees. The first transmission member 14 is wound around the driving member π and the receiving groove 125 of the driven wheel 123 of the first follower 12. The number of turns of the first transmission member 14 on each of the receiving slots 125 of the first follower member 12 is smaller than the number of turns remaining on the receiving slot 25 to ensure the realization of the transmission. The first transmission member 14 may be a steel wire rope and a steel belt structure 'as long as it has sufficient strength and bobness' to ensure a good transmission. In the present embodiment, the first transmission member 14 is a steel wire rope. [0014] 099107593 The second transmission member 15 is wound around the driven shaft 121 of the first follower 12 and the receiving slot 1317 of the second slave form number A0101, page 5 of 18, 0992013687-0, 201132878. The second transmission member 15 may be a wire rope, a steel belt or the like as long as it has sufficient strength and toughness to ensure good transmission. The number of the second transmission members 15 can also be determined according to factors such as the actual required strength and the size of the speed reduction mechanism 100. In the present embodiment, the second transmission member 15 is a steel cord, and there are two. Referring to FIG. 4 and FIG. 5 , in the embodiment, there are four fixing members 16 , and two of them are used for fixing the end of the first transmission member 14 to the two driven wheels 123 of the first follower 12 . The other two are used to fix the end of the second transmission member 15 to the transmission portion 131 of the second follower 13. Each fixing member 16 includes a positioning block 1 61, an adjusting block 16 3 , a disc-shaped elastic piece 16 5 , a connecting rod 167 and a screw 169 〇 [0016] The power component 30 is a motor 'including the body 31 and the: dust '3 =1 Rotate the connected rotation axis (not shown). [0017] The bracket 50 includes a bottom plate 51, side plates 53 extending perpendicularly from opposite edges of the bottom plate 51, and two connecting plates 55 extending from the middle portion of the bottom plate 51. The connecting plate 5 5 and the side plate 5 3 are respectively located on the opposite sides of the bottom plate 51. [0018] Referring to FIG. 1 to FIG. 5, when the fascia mechanism is assembled, the opposite ends of the rotating shaft 137 of the second follower 13 are respectively received in the two connecting plates η of the bracket 5, and The connecting plate 55 is rotatably connected. The body 31 of the power component 3 is fixed on one side plate 53 of the bracket 50, and the driving member π passes through the through hole 135 of the second follower 13 and one end passes through the side plate 53 and the power component 3 The rotary shaft is rotatably connected to the other end through the other side plate 53' and is rotatably coupled to the side plate 53. The two ends of the first follower 12 pass through the two side plates 53, respectively, and are rotatable relative to the two side plates 53. The axis of the driven shaft 121 of the first follower 12 is 099107593 Form No. A0101 Page 6 of 18 0992013687-0 201132878 The axis of the active member 11 is substantially parallel. After the first transmission member 14 is wound on the driving member, the two ends are respectively wound around the receiving groove 125 of the second driven wheel 123 of the second-the driven member 12. The two ends of the first transmission member 14 are fixedly coupled to the two driven wheels 123 by a fixing member 16, respectively. The fixing block 161 is fixed on the driven wheel 123 by the screw 169. The connecting rod 167 passes through the disc spring 165 and the adjusting block 163 and is fixedly connected with the positioning block ΐ61. After the adjustment block 163 is inserted, it is screwed into the adjustment block 163 by the screw 169. Further, the fixing member _ fixes the other end of the second transmission member 15 to the other driven pulley 123 in the same manner. The two second transmission members 15 are wound around the driven shaft 121 between the two driven wheels 123 of the first follower 12, and then wound into the second driven member 13 and respectively received in the two spaced apart portions. The receiving groove 1317 is in the middle. The two ends of each of the second transmission members 15 are respectively fixed to the two side walls 1313 of the second driven member 13 by fixing members 16 in the same manner as the ends of the first transmission member 14. [0019] When the speed reduction mechanism 100 is in operation, the power unit 30 drives the driving member u to rotate, which is convenient for description. In the present embodiment, it is assumed that the active partner 11 is rotated in the X direction (that is, rotated in the clockwise direction). When the driving member turns in the sense direction, the portion of the first transmission member 14 that is close to the power member 3 is gradually circulated from the driving member 11 and wraps around the first follower 12 near the driven member 123 of the power member 3? In the accommodating groove 125, the portion of the first transmission member 14 remote from the power member 3 is then circulated from the accommodating groove 125 of the other driven wheel 123. The first follower 12 rotates in the opposite direction of the X direction under the driving of the first transmission member 14, so that the second transmission member 15 wound on the driven shaft 121 of the first follower 12 is partially wound into the first cymbal. The second follower 13 is rotated in the direction of the housing 13 of the movable member 13 and the other portion from the adjacent housing 099107593 Form No. A0101 Page 7 / 18 pages 0992013687-0 201132878 (4) (4). After the driving member 11 rotates in the X direction - after the number of turns, the power component 30 automatically adjusts the reverse direction of the driving member 11 / α χ direction correspondingly, the first - the follower: 2 will rotate in the Χ direction, the second The follower 13 will rotate in the opposite direction of the X direction. [0020] The present invention (4) is described as a wire-weaving device by means of the material-(four) member I and the second follower member 13, eliminating the need for gears. Such a complicated structure, the structure is simple, and the production cost is low. __In the transmission process disk, the active member 11, the first follower 12 and the second follower 13 are wound/received and do not have a backlash. The transmission is relatively smooth and efficient. The arrangement of the first follower 12 and the second follower 13 can realize multi-stage transmission, and the manner of the driven shaft 121 and the driven wheel 123 of the first follower 12 is such that the first follower 12 is It is the driven component of the upper transmission and the active component of the next transmission, which saves components. The through hole 135 opened in the second follower 13 is advanced so that the transmission portion 131 has a hollow structure 'to allow the active phase to pass therethrough, so that the speed reduction mechanism is just compact. Step by step, g] material 16 towel dish turn Sichuan 5 borrow (four) sexual restoring force to keep the first transmission member 14 and the second transmission member 15 in tension, when the first transmission member 14 or the second transmission member 15 After the long-term use, when the looseness exceeds the range in which the elastic restoring force of the disk-shaped elastic piece 165 can be tightened, the disk-shaped elastic piece 165 can be retracted by the screw connecting rod 167, so that the first transmission member 14 or the second transmission member 15 is again Tightened to avoid slipping and other conditions. [0022] 099107593 It can be understood that the driven wheel 123 of the first follower can also be provided only one, and the two ends of the first transmission member 14 are fixed to the driven wheel 23, correspondingly, the form number A0101 is required. / Total] 8 pages 0992013687-0 201132878 Change the number of laps of the accommodating groove 125 opened on it to ensure the deceleration transmission.
