Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the damping device embodiment of the utility model driving mechanism;
Fig. 2 is the sectional view along D-D direction in the damping device embodiment of the utility model driving mechanism.
Embodiment
As shown in Figure 1, a kind of damping device of driving mechanism, comprise input tooth bar 13, export tooth bar 9 and switching mechanism, wherein, switching mechanism comprises drive pin 6, rotating shaft 5 and is sheathed on input gear 4, input disc 8, output disc 10 and the output gear 11 in rotating shaft 5 in turn, drive pin 6 is connected with input disc 8 and vertical with input disc 8, output disc 10 is provided with the curve bath 7 coordinating drive pin 6, input gear 4 and input disc 8 are fixed and relatively rotate with rotating shaft 5, and output gear 11 and output disc 10 are fixed and fixed with rotating shaft 5; Input tooth bar 13 engages with input gear 4, exports tooth bar 9 and engages with output gear 11; Also be provided with push rod 3, roller 2 and cam 1, cam 1 is connected with gantry rotation, push rod 3 one end is connected with input tooth bar 13 one end, push rod 3 the other end connects roller 2, roller 2 and cam 1 offset, cam 1 turns to the corresponding position being positioned at curve bath 7 two ends with drive pin 6, and the part that roller 2 contacts with cam 1 is respectively jacking arc (being illustrated as near A point) and decline arc (being illustrated as near C point), and jacking arc and decline arc can coordinate the rising or falling speed reducing input tooth bar 13.The jacking arc part of cam 1, the point on cam 1 surface increases progressively to the distance of cam 1 center of rotation, and variance ratio is very little; In the decline arc part of cam 1, the point on cam 1 surface successively decreases to the distance of cam 1 center of rotation, and variance ratio is very little, so the speed of drive pin 6 at collision curve bath 7 two ends slowly, little to the impact of drive pin 6.
In the present embodiment, be also provided with guide fork 14 and maintainance block 15, guide fork 14 one end is connected with push rod 3, maintainance block and cam 1 axle are rotationally connected, and maintainance block 15 is stuck in guide fork 14, push rod 3 is reinforced by guide fork 14 and maintainance block 15, reduces roller 2 play in cam 1 surface scrolls process.
Output gear 11 is connected with rotating shaft 5 by key 12, and the mode connected by key is simple, and easy maintenance and replacement parts.
Concrete use flow process:
As shown in Figure 1, when cam 1 rotates counterclockwise, roller 2 is at the surface scrolls of cam 1, thus push rod 3 is moved up, now input tooth bar 13 to move back and forth thereupon, the input gear 4 engaged with input tooth bar 13 rotates counterclockwise, and drive input disc 8 to rotate counterclockwise, drive pin 6 is positioned on input disc 8, and this drive pin 6 coordinates with the curve bath 7 that output disc 10 is offered, when cam 1 turns to the position near diagram A point, drive pin 6 turns to the adjacent one end of curve bath 7, then drive pin 6 driver output dish 10 rotates counterclockwise, be rotated counterclockwise with the output gear 11 that output disc 10 is fixing, the output tooth bar engaged with output gear 11 9 is moved to the left.
When the position that cam 1 throw of eccentric is maximum go to contact with roller 2 time, input gear 4 moves to peak, near illustrated B point, input gear 4 moves down subsequently, input gear 4 is driven to rotate clockwise, now drive pin 6 moves in curve bath 7, export tooth bar 9 static, when cam 1 goes near illustrated C point, drive pin 6 turns to another end of curve bath 7, drive pin 6 drives output disc 10 to turn clockwise subsequently, and output gear 11 rotates thereupon, and the output tooth bar 9 engaged with output gear 11 moves right.
Rotate a circle in process at cam 1, input gear 4 realizes rotating and reverse two actions, so the drive pin 6 on input disc 8 understands two ends conversions of the curve bath 7 on output disc 10, because cam 1 turns to the corresponding position being positioned at curve bath 7 two ends with drive pin 6, the part that roller 2 contacts with cam 1 is respectively jacking arc (being illustrated as near A point) and decline arc (being illustrated as near C point), jacking arc and decline arc can coordinate the rising or falling speed reducing input tooth bar 13, so near these two positions time, the ratio of the input displacement of tooth bar 13 and cam 1 rotation angle is very little, drive pin 6 towards the motion of curve bath 7 end slowly, the impact at drive pin 6 pairs of curve bath 7 two ends is very little, the impact force that drive pin 6 is subject to is less, so drive pin 6 is not easy fracture.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
