Abstract
The utility model discloses a pin gear track driving device which comprises a driving motor (1). The pin gear track driving device is characterized in that the driving motor (1) is connected with a rotating shaft (2) through a reduction gearbox; the two end parts of the rotating shaft (2) are respectively in key joint with pin gear discs (3) adopting the same structure; a plurality of rotatable pin gears (4) are uniformly arranged on the circumference of each pin gear disc (3); each pin gear disc (3) is matched with a track (5); grooves (6) are formed at intervals in the upper end of each track (5); the grooves (6) are matched with the pin gears (5) in shape; and the interval between every two adjacent grooves (6) is matched with that between every two adjacent pin gears (4). The pin gear track driving device is simple in structure and unique in design and can realize long-distance linear driving.
Description
Technical field
The utility model relates to a kind of drive unit, particularly a kind of pinwheel rail driving device.
Background technique
Utilize motor to realize that as original driving source straight-line mechanism has a lot, but be the various variant structures of gear, tooth bar or worm gear, worm screw mostly, and the crow flight distance that drives if desired is longer, just need the very long tooth bar of length or worm screw, one side processing difficulties, inconvenience, cost also can rise significantly on the other hand, and if adopt the mode of many toothed rack splicing, then might cause variety of problems because of processing or alignment error.Therefore need a kind ofly can address the above problem now, can satisfy long apart from driving structure or the device realizing transmitting.
Summary of the invention
The utility model is in order to solve the above-mentioned deficiency of existing in prior technology, proposes a kind of simple in structurely, designs ingeniously, can realize long pinwheel rail driving device apart from linear drives.
Technical solution of the present utility model is: a kind of pinwheel rail driving device, comprise drive motor 1, it is characterized in that: described drive motor 1 links to each other with rotating shaft 2 by speed reducer, the two end part of rotating shaft 2 key respectively are connected with the identical pinwheel dish 3 of structure, evenly be provided with a plurality of rotary pinwheels 4 on the circumference of pinwheel dish 3, be provided with track 5 with each pinwheel dish 3 matches, the upper end of each track 5 is provided with the groove 6 that arranges at interval, the shape of groove 6 and pinwheel 4 coincide, and adjacent two grooves 6 equate with pitch between adjacent two pinwheels 4.
The utility model is compared with prior art, has following advantage:
The pinwheel rail driving device of this kind of structural type, it is simple in structure, designs ingeniously, matches on the pinwheel dish that its utilize to rotate and the track and realizes that straight line motion exports; In the pinwheel dish rotating process, the groove of the pinwheel that arranges on its circumference on just can injection, because track relative fixed, therefore the rotation of pinwheel dish just can change straight line motion into, this have with the pinwheel dish match groove track processing on simple, also be easy to control on the cost, most importantly it can process long distance very easily, provides new approaches for long apart from the straight line transmission.Therefore we can say that it has possessed multiple advantage, be particularly suitable for applying in the art that its market prospects are very wide.

Fig. 1 is the utility model embodiment's plan view.
Fig. 2 is the structural representation that the utility model embodiment pinwheel dish and track match.
Fig. 3 is the sectional view of the utility model embodiment pinwheel dish.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.As Fig. 1, Fig. 2, shown in Figure 3: a kind of pinwheel rail driving device, comprise as drive source drives motor 1, this drive motor 1 links to each other with rotating shaft 2 by speed reducer, be that drive motor 1 can drive rotating shaft 2 rotations, the two end part of rotating shaft 2 key respectively are connected with identical in structure pinwheel dish 3, on the circumference of this pinwheel dish 3, be provided with a plurality of rotary pinwheels 4 equably, be provided with track 5 with each pinwheel dish 3 all matches, and the upper-end surface of track 5 is provided with the groove 6 that a plurality of intervals arrange, the shape of groove 6 and pinwheel 4 match, be that pinwheel 4 can enter groove 6, and the distance between two adjacent grooves 6 equates with pitch between adjacent two pinwheels 4 on the circumference at interval, be in pinwheel dish 3 rotating process, the pinwheel 4 on it can be continuous, enter (or disengaging) corresponding groove 6 swimmingly successively.
The working procedure of the utility model embodiment's pinwheel rail driving device is as follows: start drive motor 1, rotating shaft 2 is rotated, and the pinwheel dish 3 that drives its two ends rotates simultaneously, in pinwheel dish 3 rotating process, pinwheel 4 is that round dot moves in a circle with the center of pinwheel dish 3, below some pinwheels 4 turn to, when entering in the groove 6, frictional force between groove 6 and the pinwheel 4 allows pinwheel 4 along himself medial axis rotation, and pinwheel 4 does not then rotate with respect to groove 6; In above-mentioned rotation process, because track 5 is fixing, therefore two pinwheel dishes of final realization 3 drive rotating shaft 2 and do straight line motion along track 5, and straight-line distance then depends on the length of track 5, therefore as long as the distance of track 5 is longer, can realize that just the straight line transmission of long distance drives.
