Abstract
The utility model discloses a reciprocating transmission mechanism which comprises a power ring, an eccentric shaft sliding frame, an eccentric shaft and an eccentric sleeve which are arranged in a waist-shaped groove of the eccentric shaft sliding frame and a speed reducing mechanism for driving an eccentric wheel, wherein the outer part of the eccentric shaft sliding frame is provided with an outer frame connected with the power ring; the middle parts of the upper and the lower ends of the eccentric shaft sliding frame are provided with rotating shafts movably connected with the outer frame. Due to adopting the structure, the reciprocating transmission mechanism is arranged on the circumference of the power ring so as to reduce the middle section of transmission and reduce friction force, and transmission force is more balanced. A reciprocating device does reciprocating motion on the circumference, and the eccentric shaft sliding frame is rotated around a shaft to be carried out with tiny angular adjustment so that the eccentric shaft and the eccentric sleeve are linearly contacted with the inner surface of the eccentric shaft sliding frame. The utility model overcomes the scratch defect caused by point type contact.
Description
Technical field
The utility model relates to driving mechanism, specifically relates to a kind of reciprocal driving mechanism.
Background technique
In the engineering and product of fountain, for obtain circular entad wave water shape view, can realize with electronic computer and stepper motor, retarder, but exist technical difficulty bigger that the cost height in use has certain narrow limitation.
Reciprocal driving mechanism, the dynamic ring that known a kind of mechanism such as ZL02219819.9 patent are disclosed, drive the dynamic ring back and forth movement driving mechanism, form for driving mechanism provides the power source of power.As shown in Figure 3, this mechanism can realize the dynamic ring back and forth movement, but exist some weakness and narrow limitation, because reciprocating thrust force is positioned at the below of dynamic ring horizontal plane, thrust is to drive the dynamic ring to-and-fro motion by the horizontally-guided bar by plate washer, because horizontally-guided bar straight line motion, the plate washer movement in a curve causes the guide rod support to wear and tear, behind the generation cut, the to-and-fro motion stroke is reduced, increased friction simultaneously.This structure when mounted, take up space deflection below of institute, stressed secund, structure is compact inadequately.
The model utility content
Technical problem to be solved in the utility model provides a kind of compact structure, reciprocal driving mechanism on circumference.
For solving the problems of the technologies described above, the technical solution of the utility model is a kind of reciprocal driving mechanism, comprise dynamic ring, eccentric shaft slider bar, place eccentric shaft in the eccentric shaft slider bar chute and cover, the eccentric reducing gear of drive, the outside of described eccentric shaft slider bar is provided with and the joining housing of dynamic ring; Its upper/lower terminal middle part is provided with and the movable rotating shaft that connects of housing.Described housing upper/lower terminal middle part is provided with perforation symmetrically, and the rotating shaft on the eccentric shaft slider bar is sleeved in the perforation by gasket ring.Eccentric shaft and cover were with the crop rotation circular movement when eccentric wheel rotated, rotating shaft can be rotated in the perforation of housing, back and forth device to-and-fro motion on circumference, at this moment the eccentric shaft slider bar is swayed and is made small angular adjustment, makes eccentric shaft and cover and eccentric shaft slider bar internal surface make " line " and contacts.
A kind of reciprocal driving mechanism leaves the gap between described housing and the eccentric shaft slider bar.
A kind of reciprocal driving mechanism, the middle part of described housing both sides links with the dynamic ring tangent plane respectively.
A kind of reciprocal driving mechanism, the upper and lower end portion of described housing both sides links by stiffening plate and dynamic ring respectively.
Owing to adopt said structure, compare with prior art, back and forth driving mechanism is located on the circumference of dynamic ring, has reduced the medium tache of transmission, has reduced friction, and power transmission is balance more also.The outside of eccentric shaft slider bar is provided with and the joining housing of dynamic ring; Its upper/lower terminal middle part is provided with and the movable rotating shaft that connects of housing.Rotating shaft can be rotated in the perforation of housing, back and forth device to-and-fro motion on circumference, and at this moment the eccentric shaft slider bar is swayed and is made small angular adjustment, makes eccentric shaft and cover and eccentric shaft slider bar internal surface make " line " and contacts.Overcome the wear-out defect that causes by " point " contact.
