Abstract
The present invention relates to a transmission mechanism for eccentric chain wheels for transferring motion and power. An eccentric tensioning chain wheel is arranged in the transmission mechanism composed of a driving eccentric chain wheel, a driven eccentric chain wheel and a chain, wherein one or more than one eccentric tensioning chain wheel can be arranged. The present invention is characterized in that the constant angular velocity motion is converted into equal-direction non-uniform velocity motion, or is converted into reverse-direction non-uniform velocity rotation by the transmission of the transmission mechanism for eccentric chain wheels. The mechanism can be applied to the design of a transmission device of a respective planting mechanism of a novel seedling planting machine with high speed.
Description
The present invention relates to a kind of transmission mechanism of eccentric chain wheel that is used for transmitting movement and power.
Present driving mechanism mainly contains band transmission, gear transmission, chain-driven, Eccentric Gear-drive and elliptic gear transmission etc.Band transmission, gear transmission and chain-driven are used for general transmission, they can not realize giving driven wheel with the constant angular velocity transmission of movement of driving wheel, making the angular velocity output of driven wheel is continually varying, and Eccentric Gear-drive and elliptic gear can be given the constant angular velocity transmission of movement of driving wheel driven wheel, making the angular velocity output of driven wheel is continually varying, but structure is comparatively complicated, is not suitable for long apart from transmission especially.
The object of the present invention is to provide and a kind ofly can change constant angular velocity motion and be non-uniform velocity motion, the transmission mechanism of eccentric chain wheel of change transmission direction.This mechanism can be applicable to design the transmission device in the high-speed transplanter transplanting mechanism of new generation.
The objective of the invention is to take following technological scheme to realize: be the initiatively isogonism speed motion of eccentric chain-wheel, transmit the motion to driven eccentric chain-wheel by chain, make the rotation of driven eccentric chain-wheel become variable-speed motion, in the transmission mechanism of eccentric chain wheel of forming by active eccentric chain-wheel, driven eccentric chain-wheel and chain, eccentric tension sprocket is set, and eccentric tension sprocket makes chain keep the degree of tightness unanimity at movement process; Two eccentric tension sprockets can be set in transmission mechanism of eccentric chain wheel, like this, the constant angular velocity motion can be become variable-speed motion, make the direction of rotation of active eccentric chain-wheel and driven eccentric chain-wheel simultaneously by the eccentric chain-wheel transmission.
The invention has the advantages that:
1. the initiatively constant angular velocity of eccentric chain-wheel motion by the eccentric chain-wheel mechanism driving, makes the rotation of driven eccentric chain-wheel become variable-speed motion.
2. by several eccentric tension sprockets are set, make the reverse variable-speed motion of driven eccentric chain-wheel.
3. make and keep the degree of tightness basically identical in the chain transmission process.
4. be fit to the transmission of longer distance.
Below in conjunction with accompanying drawing the present invention is elaborated:
Fig. 1 is an a kind of embodiment's of the present invention structural representation.
Fig. 2 is an another kind of embodiment's of the present invention structural representation.Among the figure: 1. eccentric chain-wheel 2. driven eccentric chain-wheel 3. eccentric tension sprocket 4. eccentric tension sprocket 5. chains 6. driving shafts 7. driven shafts initiatively
According to embodiment shown in Figure 1: the present invention includes initiatively eccentric chain-wheel 1, driven eccentric chain-wheel 2 and chain 5, an eccentric tension sprocket 3 is set in this mechanism.The constant angular velocity of driving shaft 6 is rotated, make initiatively eccentric chain-wheel 1 and chain 5 rotations, make driven eccentric chain-wheel 2 (driven shaft 7) with variable-speed motion in the same way, the degree of tightness that relies on eccentric tension sprocket 3 to solve chain 5 in the transmission changes, and makes chain 5 be unlikely to too tight or too loose at work.
According to embodiment shown in Figure 2: the present invention includes initiatively eccentric chain-wheel 1, driven eccentric chain-wheel 2 and chain 5, two eccentric tension sprockets 3 and 4 are set in this mechanism.The constant angular velocity of driving shaft 6 is rotated, make initiatively eccentric chain-wheel 1 and chain 5 rotations, and driven eccentric chain-wheel 2 (driven shaft 7) relies on eccentric tension sprocket 3 and 4 to solve the degree of tightness variation of chain 5 in the transmission with reverse variable-speed motion, makes chain 5 be unlikely to too tight or too loose at work.
The eccentric chain-wheel transmission changes for satisfying desired speed ratio, but appliance computer calculates throw of eccentric size and the two core wheel initial phase differences of determining its active eccentric chain-wheel 1 and driven eccentric chain-wheel 2.The position of eccentric tension sprocket 3,4 and and the initial angle displacement utilize computer optimization to calculate.
Can use the transmission device in this mechanism design a new generation high-speed transplanter transplanting mechanism.
