By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
embodiment 1
As shown in Figure 1, the utility model is a kind of driving mechanism with reverse self-locking structure, as depicted in figs. 1 and 2, this product is a kind of driving mechanism with reverse self-locking structure, it is comprised frame and one and is fixed on pto＝power take-off 8 in frame by bearing, pto＝power take-off 8 is fixed with internal tooth wheel disc 1 successively, power input gear 5, as Fig. 4 wherein power input gear 5 be fixed by socket on the input shaft that is connected with output shaft rotation at one, power input gear 5 is coaxially fixed by input shaft and internal tooth wheel disc 1, power input shaft 7 wherein one end is also connected with gantry rotation by bearing,
Output shaft is gone back eccentric setting and has a cylindrical drive block 6, cylindrical drive block 6 is e with the throw of eccentric of input shaft, output shaft, driving block 6 is socketed with a planetary pinion 2, be slidably connected between the round and outer surface of driving block 6 in planetary pinion 2 center, as Fig. 3, planetary pinion 2 also engages with the internal tooth on internal tooth wheel disc 1, gear ratio internal tooth wheel disc 1 number of teeth few 1 ~ 5 of planetary pinion 2;
Position in frame between corresponding power input gear 5 and internal tooth wheel disc 1 is provided with cross slide way and longitudinal rail, wherein cross slide way comprises a guide plate 3 be arranged between planetary pinion 2 and power input gear 5, be provided with a radius at the middle part of guide plate 3 and equal eccentric distance e, the rotation hole 3-1 of cylindrical drive block 6 radius sum, the edge of rotation hole 3-1 is symmetrical arranged and is provided with two sliding-groove 3-2, on planetary pinion 2, the positional symmetry of corresponding sliding-groove 3-2 is provided with two slide blocks 2-1 simultaneously, slide blocks 2-1 is embedded in sliding-groove 3-2, do linear reciprocation along sliding-groove 3-2 to move,
As Fig. 5, longitudinal rail comprises and is arranged on guide plate 3 both sides, between two symmetry and is symmetrically arranged with four supporting posts 4, the axis of supporting post 4 and the axis being parallel of pto＝power take-off 8, the both lateral sides edge of guide plate 3 and the wall contacts of supporting post 4, carry out cross spacing by four supporting posts, 4 pairs of guide plates 3, guide plate 3 is the moving back and forth of intercropping longitudinal direction of four supporting posts 4.
During forward transmission, the principle of this structure for convenience of description, as shown in Figure 6, it is a planet-gear transmission mechanism comparing simplification, comprise a fixing internal tooth torus 9, the support of a fixed crankshaft 11, and two the planetary pinion A10-1 be fixed on bent axle and planetary pinion B10-2, two curved bars that planetary pinion A10-1 and planetary pinion B10-2 is fixed on bent axle engage with internal tooth torus 9 respectively, in frame, be also rotatably connected to an output shaft 12 simultaneously, the rotation axis of output shaft 12 and the coaxial of bent axle 11, on planet gear A 10-1 and planetary pinion B10-2, equal annular is processed with some movable spans, output shaft 12 is provided with a driving plate 13, driving plate 13 is provided with some driveshafts 14 be inserted in movable span, the diameter of driveshaft 14 is less than the direct of movable span, pass through driving crank, make planetary pinion A10-1 and planetary pinion B10-2 mobile in internal tooth torus 9, because relative output shaft 12 radius of gyration of movable span is greater than the radius of gyration of curved bar on bent axle 11, export so last power is slowed down by output shaft 12,
