Background technology:
Cyclotron oscillation device is the important device of chemistry, biological experiment and production, for carrying out shaken cultivation to various liquid state, the solid compounds such as bacterial classification, cell in biological, biochemical test.Cyclotron oscillation device requires to possess and starts the performance slim and graceful, frequency is stablized, hunting range is wide, load capacity is large, noise is low, but, traditional cyclotron oscillation device/shaking table uses three eccentric wheel motor drag convolution supports, actual use in have that swing angle resistance is large, rotary speed unstabilization, starting torque and the problem such as load is little, low speed cannot drag, performance is unsatisfactory, is necessary to be improved.
Summary of the invention:
Object of the present invention be just for prior art exist weak point and a kind of modified cyclotron oscillation device is provided, its have rational in infrastructure, start slim and graceful, convolution is stable, load is large, vibrate little, that noise is low feature, can meet the scientific research needs to cyclotron oscillation culture experiment and production better.
For achieving the above object, modified cyclotron oscillation device of the present invention includes the shell be made up of face-piece and base plate, be provided with motor, speed reduction gearing, eccentric shaft, convolution lower carriage and convolution upper bracket in shell, wherein, motor is via speed reduction gearing and drive the lower carriage that circles round
And the eccentric shaft that convolution upper bracket does cyclotron oscillation motion is connected, and is connected, passes through second group of damping steel disc connected between convolution lower carriage and convolution upper bracket between described convolution lower carriage and the bearing in shell by first group of damping steel disc; First group of described damping steel disc and second group of damping steel disc form by two panels damping steel disc; Wherein, the two panels damping steel disc of first group of damping steel disc is set in parallel in the both sides up and down of convolution lower carriage, and the two panels damping steel disc of second group of damping steel disc is set in parallel in the left and right sides of convolution lower carriage and convolution upper bracket; Described base plate rear end face is provided with beam.
Preferred as technique scheme, described speed reduction gearing is made up of little profile of tooth belt wheel, Timing Belt and eccentric shaft toothed belt wheel, wherein, little profile of tooth belt wheel is fixed in the rotating shaft of motor, Timing Belt is connected with little profile of tooth belt wheel and eccentric shaft toothed belt wheel, and eccentric shaft is fixed on the front end of eccentric shaft toothed belt wheel.
Preferred as technique scheme, described eccentric shaft toothed belt wheel rear end is provided with photoelectric velocity measurement dish.
Preferred as technique scheme, described eccentric shaft toothed belt wheel side is fixed with balancing weight.
Beneficial effect of the present invention is: it adopts single eccentric shaft to drive convolution lower carriage and convolution upper bracket to do cyclotron oscillation motion, in addition, the tension force of two groups of damping steel disc generations can overcome the resistance of eccentric motion corner, the plane convolution of support of making to circle round produces without the component of horizontal direction, having coherent stable, the moment of circling round of motion greatly, advantage that good rigidly, noise are low.

Detailed description of the invention:
See shown in Fig. 1 and Fig. 2: a modification of the present invention type cyclotron oscillation device, include the shell 10 be made up of face-piece 11 and base plate 12, motor 20, speed reduction gearing 30, eccentric shaft 40, convolution lower carriage 50 and convolution upper bracket 60 is provided with in shell 10, wherein, motor 20 via speed reduction gearing 30 and drive circle round lower carriage 50 and the upper bracket 60 that circles round to do eccentric shaft 40 that cyclotron oscillation moves is connected; Speed reduction gearing 30 is made up of little profile of tooth belt wheel 31, Timing Belt 32 and eccentric shaft toothed belt wheel 33, wherein, little profile of tooth belt wheel 31 is fixed in the rotating shaft of motor 20, Timing Belt 32 is connected with little profile of tooth belt wheel 31 and eccentric shaft toothed belt wheel 33, and eccentric shaft 40 bias is fixed on the front end of eccentric shaft toothed belt wheel 33.Eccentric shaft toothed belt wheel 33 rear end is provided with the photoelectric velocity measurement dish 80 measuring cyclotron oscillation rotating speed.In addition, more steady for making eccentric shaft toothed belt wheel 33 run, eccentric shaft toothed belt wheel 33 side is fixed with balancing weight 34.
Be connected by first group of damping steel disc 70 between convolution lower carriage 50 and the bearing 13 in shell 10, be connected by second group of damping steel disc 71 between convolution lower carriage 50 and convolution upper bracket 60.First group of damping steel disc 70 and second group of damping steel disc 71 form by two panels damping steel disc; Wherein, the two panels damping steel disc of first group of damping steel disc 70 is set in parallel in the both sides up and down of convolution lower carriage 50, and the two panels damping steel disc of second group of damping steel disc 71 is set in parallel in the left and right sides of convolution lower carriage 50 and convolution upper bracket 60.
In addition, base plate 12 rear end face is provided with the beam 90 of multiple quality of rubber materials, with reduce cyclotron oscillation device work time vibrations and noise.
