The invention relates to the technical field of biological cells, and discloses a speed-limiting transmission device for stepless adjustment of the rotational speed of a biological cell centrifuge, which includes a driving shaft, an electric coil is fixedly connected to the inside of the driving shaft, and the axis of the driving shaft is A rotating shaft is rotatably connected, and an active rod is movably clamped on the outer surface of the driving shaft. The central end of the active rod is rotatably connected to a transmission rod. The surface of the ring is movably connected with a transmission belt, the side lower end of the driving shaft is fixedly connected with a return spring, the lower end of the return spring is fixedly connected with a sleeve block, the bottom end of the sleeve block is fixedly connected with an arc groove, and the inside of the arc groove The speed-limiting spring is fixedly connected, and the bottom end of the speed-limiting spring is fixedly connected with a weight. The speed-limiting transmission device of the biological cell centrifuge with infinitely adjustable rotational speed achieves the effect of constant rotational speed of the centrifuge through the cooperation of return springs, sleeve blocks, arc grooves, speed-limiting springs and weights.
Description
technical field [0001] The invention relates to the technical field of biological cells, in particular to a speed-limiting transmission device for stepless adjustment of the rotational speed of a biological cell centrifuge. Background technique [0002] Currently, centrifuge equipment is basically used in the biological cell separation step, which is often used to separate the solid phase and liquid phase in the colloidal solution. In the actual use of the centrifuge, the requirements for the speed of the centrifuge are extremely strict. Different speeds can separate different organelles. The speed of the centrifuge will change due to external factors such as unstable voltage and vibration of the receiving equipment. If the rotation speed is too fast, the organelles that need to be kept may rupture, while if the rotation speed is too slow, the separation of the organelles may not be complete. In addition, because the speed adjustment structure of some equipment adopts hiera...
