According to a recent study by researchers at Pennsylvania State University's School of Engineering, a major technological advance has been made in the area of ​​high-speed beam-scanning equipment where print speeds in both 2D and 3D are up to 1000 times faster.
Using the space charge controlled tantalum niobate beam deflector, a crystal made of lithium potassium niobate and potassium niobate with a large electro-optic effect, the researchers found that it is possible to achieve higher speed scanning.
"Basically, when the crystal material is used in an electric field, it produces a uniformly distributed reflection that deflects the incident beam," said Shizhuo Yin, an electrical engineering professor at the School of Electrical Engineering and Computer Science. "We conducted a systematic study of the adaptation to velocity and found that the phase transition of the electric field is one of the limiting factors."
To overcome this problem, Yin and his team of researchers, including Wenbin Zhu, Ju Hung Chao and Chang-Jiang Chen from Pennsylvania State University and Robert Hoffman from the Army's Army Research Laboratory in Maryland, Temperature environment in order to eliminate the disordered potassium tantalate niobate crystal induced by the electric field induced phase transition. Not only did they go beyond the Curie temperature (ie, some materials lose their magnetic properties at this temperature, thus displacing them to induce magnetism), they also surpass the critical end point where the liquid and its vapor coexist.
This increases the scanning speed from the microsecond range to the nanosecond range and improves the technology of high-speed imaging, broadband optical communication, ultra-fast laser display and printing.
The team's findings have been published in the Journal of Science, a British interdisciplinary magazine.
Yin says technologies like this will be particularly relevant, such as enabling real-time, high-speed imaging in the medical industry. As another example, using a noninvasive imaging technique, lightwaves are used to take a cross-sectional picture of a human retina and to give them a three-dimensional image of the retina of their patient at the time of surgery so they can see where they still need surgical correction .
Yin added that the study could benefit everyone and took about an hour in the past to take advantage of 3D printing, which now takes only a few seconds, compared to 20000 for two-dimensional printing in just a minute.
The differential cross shaft,Differential Spider, mounted in the drive axle main drive differential, supports the planetary bevel gears and, together with the half-shaft gears, enables differential speed
Common accessories of drive axle:Loader Drive Axle Assembly, including: axle housing, Loader Reducer Assembly, Loader Differential Assembly, half shaft, wheel rim inner gear ring, planetary frame assembly, hub, Loader Rim Assembly , Loader Brake Clamp ,loader brake pads, hub and bearings, etc
The role of the drive axle is: 1, reduce speed and increase torque; 2. Change the direction of power transmission and transfer power; 3. Make the left and right wheels rotate at different speeds to meet the steering requirements; 4, bearing the gravity of the frame and the body. The drive axle is composed of main reducer, differential, half shaft and axle housing. The function of the drive axle is: 1. The engine torque from the universal transmission device is transmitted to the driving wheel through the main reducer, differential and half shaft to achieve speed reduction and torque increase; 2. Change the transmission direction of torque through the bevel gear of the main reducer; 3, to achieve differential speed, to ensure the inner and outer wheels to turn at different speeds; 4. Realize load bearing and torque transmission.
