The specific embodiment
The utility model carries out Optimal Structure Designing, to increase the balance shaft 7 of joining with existing vibrating shaft 6 contrarotations, offsets the non-linear moment of torsion outside directional vibration.
Realize involving vibrations axle 6 in device of the present utility model, balance shaft 7 and eccentric block 8.
Concrete, side at the vibrating shaft 6 of setting-up eccentricity piece 8 increases balancing axle 7, and the configuration secondary eccentric block identical with eccentric block 8 total weightes on vibrating shaft 6 is as balance weight on balance shaft 7, vibrating shaft 6 is contrary with balance shaft 7 hand of rotation, the eccentric block 8 of installing on vibrating shaft 6 or balance shaft 7 or the center of gravity of secondary eccentric block lay respectively at vibrating shaft 6 or balance shaft 7 in the heart.
The utility model produces the vibratory drive of linear power output, vibration angle is adjustable, when balance shaft 7 Relative Vibration axles 6 rotate backward, can produce linear power output, because therefore propulsive effort can not produce moment of torsion through equipment center of gravity, and can adjust angle of throw by the phase relation changing between balance shaft 7 and vibrating shaft 6.Adopt the linear vibration better quality of the vibratory equipment generation of this type of drive, move controlled.
Below in conjunction with drawings and Examples, further illustrate.
Embodiment 1: delivery system is single motor-driven 3 eccentric shaft piece type of drive.As shown in accompanying drawing 1,2,3, vibratory drive system has three parallel main shafts, two vibrating shafts 6 in outside turn to unanimously, and contrary with intermediate equilibria axle 7, on two vibrating shafts 6 outside being positioned at, be separately installed with the eccentric block 8 of same weight, and intermediate equilibria axle 7 is provided with the secondary eccentric block of two times of weight.When equipment moves like this, the bias of generation is just linear pattern with joint efforts, 14 vibrations of driving arrangement delivery chute.
In the present embodiment, vibration chutes 14 or delivery board are welded on two rectangular tubes 15, then by rectangular tube 15, are connected to driver element.Delivery chute 14 bottoms are supported to be arranged on static ground by one group of isolation spring 16.
In aforementioned, two vibrating shafts 6 in outside and the balance shaft at middle part 7 are installed in a framework driving arm 17, same, also can be arranged in the framed structure on delivery chute 14 tops.After being positioned at intermediate equilibria axle 7 location, make resultant direction pass through vibratory equipment center of gravity.
In aforementioned, a cone belt 2 connects motor pulley 1 and drive wheel 3, this drive wheel 3 is connected with balance shaft 7 one end axles, balance shaft 7 other ends connect timing belt pulley 11, timing belt pulley 11 drives the same side of other two vibrating shafts 6 by a double cog synchronous belt 13 and idle pulley 12, two vibrating shafts 6 and balance shaft 7 synchronous backwards are rotated, idle pulley 12 is installed and is contributed to tensioning Timing Belt 13.Therefore, can drive intermediate equilibria axle 7 rotation directions reverse with the vibrating shaft 6 of both sides all the time by separate unit motor.
In aforementioned, balance shaft 7 middle parts are installed secondary eccentric block and are adopted hard connecting mode to fix.
In aforementioned, between vibrating shaft 6 and balance shaft 7, distance is greater than the maximum outside diameter of eccentric block 8.Between vibrating shaft 6 and balance shaft 7, reserve sufficient space, collision while preventing weight block rotation.
