Abstract
The utility model relates to a power and tunable frequency eccentric shaft cylinder vibration exciter is mainly installed two pairs of eccentric excitation pieces of anti vibration drive machine, eccentric excitation axle and the contained angle adjustable that take at both ends on vibration carrier curb plate, is installed initiative turriform belt pulley on electric motor rotating shaft, is installed at the epaxial driven turriform belt pulley of eccentric shaft transmission, driving belt, is formed to the take -up pulley of belt etc. With appropriate stability factor spring top by the seat formula of inserting. By the drive ratio that forms the difference that pairs of different diameters initiative turriform belt pulley and driven turriform belt pulley, through adjusting the exciting force that two eccentric block contained angles formed the variation in size. Through two or many power and tunable frequency eccentric shaft cylinder vibration exciter's aggregate erection, the vibration of different mode of vibration orbits and different excitation developments parameter is realized to excitation vibration carrier. Broken through because of the limitation of drive machine rotational speed design and eccentric shaft exciting force are difficult to the restriction that changes, satisfied under different work condition the demand to the vibration exciter is done all can and on -the -spot convenient adjustment is carried out to the frequency.

Initiatively tower-shaped belt pulley and driven tower-shaped belt pulley carry out pairing by the tower-shaped belt pulley of different-diameter and form different gearratios, realize the different excited frequencies of eccentricity excitation axle.
Two ends, with the exciting eccentric shaft of the adjustable two pairs of coaxial eccentric blocks of angle, realize the exciting of the different exciting force of vibrator by the angle adjusting two pairs of coaxial eccentric blocks.
Installed by the combination of two or multiple stage power and frequency-adjustable eccentric shaft barrel type vibration exciter, excited vibration carrier realizes the vibration of different vibration shape track and different exciting dynamic parameter.
Antivibration driving motor adopts the seat formula of inserting to be arranged on vibrating carrier side plate, and existing tensile bolt has again to be sheared bolt and participate in being fastenedly connected of motor and vibrating carrier side plate simultaneously.
Appropriate stiffness coefficient spring top is adopted to be the smooth realization in order to follow motor synchronizing and synchronous regime stability when ensureing that driving belt has suitable skidding function to realize two or the work of multiple stage vibrator to the regulating wheel of belt.
The double shaft inertia shaker " centre of force theoretical " that proposes is taught and " non-etc. mass-radius product follow motor synchronizing and synchronous regime Theory of Stability " carries out calculating design according to Southwest Petrol University Zhang Minghong, installed by the combination of two or multiple stage power and power and frequency-adjustable eccentric shaft barrel type vibration exciter, carrier screen box just can be encouraged to realize the vibration of different vibration shape track and different exciting dynamic parameter.
Compared with prior art, advantage of the present invention is:
(1) in Ben Li and frequency-adjustable eccentric shaft barrel type vibration exciter, forming different gearratios by being arranged on the active tower-shaped belt pulley on antivibration driving motor turning cylinder with the different-diameter pairing of the driven tower-shaped belt pulley be arranged on eccentricity excitation through-drive axle, realizing the different excited frequencies of eccentricity excitation axle.The exciting of the different exciting force of vibrator is realized by the angle of adjustment eccentricity excitation axle two ends coaxial eccentric exciting block.And installed by the combination of two or multiple stage power and frequency-adjustable eccentric shaft barrel type vibration exciter, excited vibration carrier realizes the vibration of different vibration shape track and Different Dynamic characterisitic parameter.
(2) in Ben Li and frequency-adjustable eccentric shaft barrel type vibration exciter; to the regulating wheel of belt, tensioning transmission is carried out to belt owing to adopting appropriate stiffness coefficient spring top; both bel-drivenn overload protection function had been remained; the more important thing is due to bel-drivenn skidding function, what better realize eccentricity excitation axle when this is just conducive to two or the vibration of multiple stage vibrator combination of stimulation carrier follows motor synchronizing and synchronous regime stability.
(3) Ben Li and frequency-adjustable eccentric shaft barrel type vibration exciter belong to pioneering both at home and abroad, are at home and abroad showed no and Ben Li and the similar Product Report of frequency-adjustable eccentric shaft barrel type vibration exciter.
