Problems solved by technology
The orbital oscillator requires the performance of light starting, stable frequency, wide oscillation range, large load capacity, and low noise. However, the traditional orbital oscillator / shaker uses three eccentric motors to drive the orbiting support, and there are cyclotrons in actual use. There are problems such as large corner resistance, unstable speed, small starting torque and load, and failure to drag at low speeds. The performance is not satisfactory, and it is necessary to improve it.

The invention discloses an improved cyclotron oscillator. The improved cyclotron oscillator comprises an outer shell composed of a face shell and a base plate, wherein the outer shell is internally provided with an electric motor, a speed reducing transmission device, an eccentric shaft, a lower cyclotron bracket and an upper cyclotron bracket; the electric motor is connected with the eccentric shaft for driving the lower cyclotron bracket and the upper cyclotron bracket to perform a cyclotron oscillatory motion by the speed reducing transmission device; the lower cyclotron bracket and a supporting seat inside the outer shell are connected through a first group of damping steel sheets; the lower cyclotron bracket and the upper cyclotron bracket are connected through a second group of damping steel sheets. According to the improved cyclotron oscillator, the single eccentric shaft is adopted for driving the lower cyclotron bracket and the upper cyclotron bracket to perform the cyclotron oscillatory motion; moreover, tensile force generated by the two groups of damping steel sheets can overcome corner resistance of eccentric motion, so that no component force in the horizontal direction is generated by plane cyclotron of the cyclotron brackets; the improved cyclotron oscillator has the advantages of stable motion coherence, large cyclotron moment, good rigidity and low noise.
