Embodiment
Embodiment
Be clearly and completely described the technological scheme in the utility model embodiment below in conjunction with drawings and Examples, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.
Refer to Fig. 1, a kind of embodiment circular movement being transferred to sine and cosine swing Minitype transmission device of the present utility model, this Minitype transmission device includes driving wheel 1, rocking arm 2, slide block 3, chute 4, gear 5, tooth bar 6, support 7 and straight-bar 9.
Please composition graphs 1 and Fig. 2 further, be convenient to the clearer concrete structure understanding the present embodiment, Fig. 2 is the assembling schematic diagram of Minitype transmission device embodiment.
Described driving wheel 1, it is a discoid steel component with card, driving wheel 1 radius size is between 1 ~ 3 centimetre, driving wheel 1 card center has connecting shaft hole 13, the outer relative set connecting bushing 11 in connecting shaft hole 13, the motor shaft 8 of motor is penetrated connecting bushing 11 and connecting shaft hole 13, and motor shaft 8 and attachment hole 13 are rigidly connected at the position that contacts, thus can be driven by motor and make driving wheel 1 make uniform circular motion.Have in the different radii position of driving wheel 1 card some can the rocking arm hole 12 of connecting rocker arm 2,3 rocking arm holes 12 are set in the present embodiment, this rocking arm hole 12 for install can in rocking arm hole 12 rocking arm 2 of moving rotary; rocking arm 2 is the wear-resisting steel components of short cylindrical shape; rocking arm 2 diameter is between 1 ~ 3 millimeter; after one end of rocking arm 2 is housed to rocking arm hole 12; spacing fixing through the position of driving wheel 1 at rocking arm 2 by nut 21, rocking arm 2 is arranged on the object that diverse location can realize adjusting rock arm 2 radius of gyration.
The other end of the rocking arm 2 on described driving wheel 1 is flexibly connected with slide block 3 bearing type, and rocking arm 2 does the circular movement relative to driving wheel 1 with movable slider 3.Slide block 3 is a short cylinder or the wear-resisting steel components of cuboid, and slide block 3 sectional shape is circular or rectangle, and slide block 3 diameter is 3 ~ 5 millimeters, is highly 3 ~ 5 millimeters.The attachment hole of slide block 3 and the outer surface of slide block 3 all smooth and do lubricated, prevent the wearing and tearing of relative movement surface of contact.
Described chute 4 is the wear-resisting steel components at vertical direction opening, and slide block 3 is arranged in chute 4, and driving wheel 1 upper rocker arm 2 does reciprocatingly sliding on vertical direction with the relative chute 4 of movable slider 3.The bottom of chute 4 is vertically fixed on the straight-bar 9 of a wear-resisting steel, or the bottom of chute 4 is connected with straight-bar 9 is one-body molded, makes chute 4 and straight-bar 9 form inverted T-shaped structure.The two ends of straight-bar 9 are installed in two openings that support 7 has, support 7 fixations, straight-bar 9 can move horizontally in support 7, but can not move up and down, when chute 4 is driven by slide block 3, because chute 4 to be limited the motion of vertical direction by support 7, therefore chute 4 is consistent with the horizontal component movement locus of rocking arm 2, realizes chute 4 to-and-fro motion in the horizontal direction.
Described tooth bar 6 is the supine spur rack of tooth, is fixed on straight-bar 9 side, or tooth bar 6 is connected with straight-bar 9 is one-body molded, makes tooth bar 6 do identical horizontal reciprocating movement with chute 4, and tooth bar 6 material is steel or wear-resistant plastic.
Gear 5 is component supporting with tooth bar 6, material is consistent with tooth bar 6, the radius of gear 5 is between several millimeters to tens millimeters, after gear 5 is meshed with tooth bar 6, the to-and-fro motion driven gear 5 of tooth bar 6 swings, realize gear shaft 51 and repeatedly swing output, gear shaft 51 can connect the device needing oscillating motion.
Consult Fig. 3, Fig. 3 is principle schematic circular movement being transferred to sine and cosine swing Minitype transmission device of the present utility model.
By adjustment rocking arm 2 to driving wheel 1 distance of shaft centers from, rocking arm 2 circular motion radius can be changed, also can change gear 5 radius simultaneously, realize gear shaft 51 and swing amplitude of oscillation Angulation changes, if rocking arm 2 circular motion radius is much larger than gear 5 radius, pendulum angle can more than 360 °, even for weeks on end.
The motion of gear 5 axis swing sine and cosine realizes as follows:
Suppose that driving wheel 1 center of circle is in initial point O (0,0), rocking arm 2 radius of gyration of driving wheel 1 is R, does uniform rotation, then rocking arm 2 and slide block 3 tie point A (X, Y) coordinate:
X＝R×cosωt
Y＝R×sinωt
Chute 4 is in the vertical direction without motion, and substantially horizontal chute 4 speed is:
Gear 5 radius is r, and angle of oscillation speed is ω
1.
Gear shaft 51 pendulum angle is:
Therefore, pendulum angle can be changed, frequency by adjustment R, r, ω.
Circular movement is transferred to sine and cosine and swings Minitype transmission device by one of the present utility model, by adjusting rock arm position and corresponding transfer gear bar length, the accurate control of oscillating motion can be realized, the sine and cosine be converted to by the uniform circular motion that motor produces in several angle swings, and may be used for miniature oscillating engine swing arm skimulated motion.
Above-described embodiment only in order to the utility model is described and and technological scheme described by unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment, those of ordinary skill in the art should be appreciated that and still can modify to the utility model or equivalent replacement; And all do not depart from technological scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in the middle of right of the present utility model.
