The motor shaft is in parallel to the driven rotating shaft, and one end of the motor shaft is fixedly connected with an eccentric quality block of the motor shaft, the other end of the motor shaft is fixedly connected with a motor shaft gear. One end of the driven rotating shaft is fixedly connected with a driven rotating shaft gear meshed with the motor shaft gear. An eccentric quality block of the driven rotating shaft is fixedly connected with the driven rotating shaft, and the driven rotating shaft is fixed on the motherboard by two bearing supports. When the motor rotates, the driven rotating shaft rotates in the opposite direction, and the two eccentric quality blocks fixed on the driven rotating shaft of the motor shaft rotate at the same time to produce the centrifugal force. The function result of the two centrifugal forces enables the motherboard to produce a horizontal and/or vertical power superimposition, so that the motherboard vibrates. The biaxial vibration mechanism has the advantages of simple structure, low noise during operation, low production cost and simple maintenance.
Description
Technical field
The utility model belongs to the mechanical vibration equipment field, particularly relates to a kind of dual-axis vibration device.
Background technology
Present existing vibratory equipment divides two classes, and a class is a vibratory sieve, and another kind of is shake table.Vibratory sieve generally is that an eccentric massblock moves in a circle, and makes equipment produce vibration by centrifugal force, and this vibratory equipment can only can not be made the equipment of technical indicator, required precision as functional use.Existing shake table basic principle is: two rotating shafts respectively carry an eccentric massblock, it is by Motor Drive one reduction box, between reduction box and two rotating shaft is the length telescope steel link rod that two ends have universal shaft coupling device, this equipment is numerous and diverse, and the rotation of two gimbal suspensions is not only arranged during this device busy, also has the continuous variation of straight line link rod length, noise is big when therefore moving, and complexity is installed, the cost height.
The utility model content
At the defective in the above-mentioned field, the utility model provides a kind of dual-axis vibration device, this device has been drawn the advantage of above-mentioned two class devices, both small and exquisite simple, can farthest develop skill again index and precision, and this apparatus structure is simple, cost is low, noise is less during operation, and is easy to use, easy care.
The dual-axis vibration device, it is characterized in that: comprise a base plate and be installed in motor and passive rotating shaft on the base plate, described motor shaft and passive shaft parallel, motor shaft one end is fixedly connected with a motor shaft eccentric massblock, and the other end is fixedly connected with a generator shaft gear; One end of passive rotating shaft is fixedly connected with a passive shaft gear that is meshed with generator shaft gear, also is fixedly connected with a passive rotating shaft eccentric massblock in the described passive rotating shaft, and passive rotating shaft is fixed on the base plate by the diaxon bearing.
Described passive shaft gear is identical with the number of teeth and the modulus of generator shaft gear.
Described passive rotating shaft eccentric massblock is identical with the rotating torque of motor shaft eccentric massblock.
Described passive rotating shaft eccentric massblock and motor shaft eccentric massblock identical in quality, barycenter direction unanimity.
Described motor and passive rotating shaft are positioned at the homonymy of two meshing gears.
Described passive rotating shaft eccentric massblock is between the diaxon bearing of passive rotating shaft.
Described motor is a vibrating motor.
Basic functional principle of the present utility model is: in two parallel rotating shafts (one of them rotating shaft is a motor shaft) eccentric massblock has been installed separately respectively, eccentric massblock is followed rotating shaft and is rotated generation centrifugal force together, making two rotating shafts do relative direction by certain mode rotates, the utility model will produce the stack of the centrifugal force of level and vertical direction, when the pivoting moment of two eccentric massblocks is identical, two centrifugal force equal and opposite in directions that eccentric massblock produces, horizontal direction centrifugal force direction is opposite, vertical direction centrifugal force direction is identical, the synthetic of final two centrifugal force is that horizontal direction offsets, and vertical direction is superimposed.
According to above-mentioned principle, the utility model adopts a motor and a passive rotating shaft parallel with motor shaft is installed on a base plate; A motor shaft eccentric massblock and a generator shaft gear are installed respectively at the two ends of motor shaft; A passive shaft gear and a passive rotating shaft eccentric massblock also are installed in passive rotating shaft; When motor rotates by two gear effects of being meshing with each other, passive rotating shaft and motor shaft are rotated simultaneously, but direction of rotation, be fixed on two eccentric massblocks in motor shaft and the passive rotating shaft, along with rotation, produce centrifugal force, two action of centrifugal force results simultaneously, make the strength of base plate generation level and vertical direction superpose, thereby make back plate vibration.Using motor as power source in this structure, is again the rotating shaft of a setting-up eccentricity mass and travelling gear simultaneously, and many functions are replaced with ripe parts dexterously, when saving the universal scalable power transmission bull stick of reduction box, has brought many advantages.This device structure is simple, does not have long-range power transmission, and noise is low during operation, and cost of manufacture is low, safeguards simple.
When the number of teeth of the number of teeth of passive shaft gear and modulus and generator shaft gear was identical with modulus, passive rotating shaft was identical with the rotating speed of motor shaft, switched in opposite.
When the pivoting moment of two eccentric massblocks was identical, the direction of two centrifugal force was that horizontal direction is cancelled out each other, and the vertical direction mutual superposition produces vibration force in vertical direction.Make that the pivoting moment of two eccentric massblocks is identical, it is identical in quality that the easiest method is exactly two masses, and the barycenter direction is identical.
Motor and passive rotating shaft can be positioned at the both sides or the homonymy of two meshing gears, are preferably placed at homonymy, can select less relatively base plate for use like this, more compact structure, take up an area of little, conserve space.
Eccentric massblock in the passive rotating shaft can be positioned at any position in the passive rotating shaft, is preferably placed between the diaxon bearing of passive rotating shaft, and such structure makes that the utility model device is more steady.
The preferred vibrating motor of motor can adapt to the vibration that base plate produces, and prolongs the service life of whole device.
The present invention goes up the gear of installing that is meshed by two parallel axes and axle, make the diaxon switched in opposite, make that simultaneously lay respectively at eccentric block on the diaxon rotates and produce centrifugal force, the stack result of two centrifugal force makes the power of base plate generation level and/or vertical direction; When the number of teeth of passive shaft gear is identical with the number of teeth and the modulus of generator shaft gear with modulus, when the pivoting moment of two eccentric blocks was identical, horizontal direction power was offset, the vertical forces stack, and base plate produces vibration in vertical direction.This device is more suitable for producing in one direction the device of power, satisfies the Focus requirement.
