Abstract
An eccentric synchronous belt-driven mechanism includes a driving eccentric synchronous belt wheel and a driven wheel; a synchronous belt is mounted between the driving eccentric synchronous belt wheel and the driven wheel; the driven wheel adopts an eccentric synchronous belt wheel; a tensioning wheel is mounted between the driving eccentric synchronous belt wheel and the driven wheel; and the tensioning wheel adopts the eccentric synchronous belt wheel. The eccentric synchronous belt-driven mechanism has the advantages of simple structure, suitability for longer-distance and higher-speed transmission, and applicability to a transmission device of a transplanting mechanism of a rice transplanter, a punching and transplanting mechanism in a vegetable transplanting machine, a transplanting transmission device in a tobacco transplanter, and the like.
Description
Technical field
The utility model relates to a kind of driving mechanism, particularly a kind of eccentric synchronous belt drive mechanism.
Background technique
Present driving mechanism mainly contains band transmission, gear transmission, chain-driven, Eccentric Gear-drive, elliptic gear transmission, eccentric planet wheel transmission and eccentric chain-wheel transmission.Band transmission, gear transmission and chain-driven are used for the constant angular velocity transmission.And Eccentric Gear-drive, elliptic gear, eccentric planet wheel transmission and eccentric chain-wheel transmission are with the follower that passes to of the angular velocity variable speed of driving wheel, though wherein Eccentric Gear-drive, elliptic gear, the transmission of eccentric planet wheel can make follower output continually varying angular velocity, these mechanisms are not suitable for long apart from transmission.Though the eccentric chain-wheel transmission can overcome above problem, chain inertia is big in the chain wheel driving mechanism, and the driving mechanism noise is big, and is easy to wear, in the eccentric gearing process vibrations bigger, the elasticity of chain and influence tooth number relation are big.
The model utility content
The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of simple in structure, is fit to the eccentric synchronous belt drive mechanism of longer distance and fair speed transmission.
The purpose of this utility model is achieved by following technical proposals:
A kind of eccentric synchronous belt drive mechanism comprises initiatively eccentric synchronous pulley, follower, between eccentric synchronous pulley of described active and the described follower synchronous band is installed, and described follower is eccentric synchronous pulley.
In the utility model, between eccentric synchronous pulley of described active and the described follower Idle wheel is installed also, described Idle wheel is eccentric synchronous pulley.
Owing to adopt above-mentioned scheme, the utlity model has following advantage:
1) the initiatively constant angular velocity of eccentric synchronous pulley motion in the transmittance process of eccentric synchronous pulley and synchronous band, makes the rotation of follower become variable-speed motion.
2) having Idle wheel to cooperate in the transmission process is the tensioning of the driving belt of band maintenance synchronously, is fit to the transmission of longer distance and the not constant angular velocity transmission of off-centre of higher speed like this.
In sum, described model utility, eccentric synchronous belt drive mechanism has simple in structure, be fit to advantages such as longer distance and fair speed transmission, can be applicable to transmission device, the punching of vegetable transplanting machinery and the transplanting transmission device of transplanting mechanism and tobacco transplanter etc. in the slotting mechanism of rice trans-planter separate.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
In the accompanying drawing, 1---is eccentric synchronous pulley initiatively; The 2---follower; The 3---Idle wheel; 4---is with synchronously.
Embodiment
Below in conjunction with accompanying drawing, describe the embodiment of eccentric synchronous belt drive mechanism in detail.
As shown in the figure, a kind of eccentric synchronous belt drive mechanism comprises initiatively eccentric synchronous pulley 1, follower 2, is equipped with between eccentric synchronous pulley 1 of described active and the described follower 2 and is with 4 synchronously, and described follower 2 is eccentric synchronous pulley.
In the utility model, between eccentric synchronous pulley 1 of described active and the described follower 2 Idle wheel 3 is installed also, described Idle wheel 3 is eccentric synchronous pulley.
In the utility model, initiatively eccentric synchronous pulley 1 provides the power drive to be with 4 to move synchronously by power plant, thereby make follower 2 under synchronously with 4 driving, do the not rotation of constant angular velocity, the effect of Idle wheel 3 is to regulate synchronously to change with the degree of tightness in 4 transmission process, makes synchronously too tight or too loose phenomenon can not occur with 4 when working; In the utility model, change for satisfying desired speed ratio, but appliance computer calculates throw of eccentric and the core wheel starting phase angle of determining eccentric synchronous pulley 1 of active and follower 2, and the position of Idle wheel 3 and starting phase angle also available computers computation optimization obtain; This mechanism can be applicable to transmission device, the punching of vegetable transplanting machinery and the transplanting transmission device of transplanting mechanism and tobacco transplanter etc. in the slotting mechanism of rice trans-planter separate.
