It is a new method of plaary gears, which has the features of strong bearing capacity, simple structure and high efficiency.. By changing the input power of the motor, it can achieve the results of the speed change.. At the same time, it and other transmission have many differences, such as if not through changing transmission ratio reached down and increase the effect of torsion, increase speed and decrease torque, only through the input power increases or the input power is reduced to increase or reduce the output rotation speed. This paper mainly carries on the design of the plaary gear, including the modulus, the number of teeth, the diameter of the dividing circle, the height of the teeth, the coefficient of the radial clearance, the design of the shaft and the selection of the material.. Key words: electric vehicle plaary gearbox, gearbox and axle calculation 23 您好，為你提供優(yōu)秀的畢業(yè)論文參考資料，請(qǐng)您刪除以下內(nèi)容， O(∩_∩)O 謝謝?。?！A national survey was recently launched to evaluate the eye health of Chinese children June 6, China39。s digitized society, will also be attached on the report.Myopia is not only a disease that makes people see things blurrily, but also leads to severeplications, such as glaua (increased pressure within the eyeball), and can causeblindness, said Zhou Yuehua, an established eye care specialist with Beijing TongrenHospital.It is very important for parents and children to know about the risk and care for their eyes.There are about 450 million myopia patients in China. Among Chinese myopia patients,30million are severe patients, according to ZhouThe prevalence of myopia among high school and college students is more than 70 percent,and the situation is continuously worsening, he Zhu, director with the China Youth Development Service Center, said long hours ofstudy, lack of exercise, especially outdoor activities, and attachment to electronic screen aresome of the top reasons behind the widespread myopia problems, and the increase ofyounger patients, although China has made great progress in improving the hardwarefacilities and lighting conditions in said he hopes the survey will alert people on the threatening situation, and also helpmedical experts to better guideline parents and children39。s work can be a way to unwind. It is true for He Wenjun, whose workplace is right near the forest park. She discovered her athletic aptitude at the age of seven, when she began playing tennis. Then she turned to jogging, and she has persevered with it for 10 years. I e to jog almost every day after work, whenever I have time. I think jogging is good for my health. And for me, a girl, it helps me to achieve to eternal goal, to keep slim, He said. He says she prefers jogging alone, so she can focus better. She loves jogging, even during Beijing39。ll hold off jogging for a while. But if I really want to get away from work, I39。s health. Poor technique harms the muscles and skeleton, and can cause secondary injures. And, jogging in a bad environment can cause circulation problems, said Lu Zhiyong, attending doctor, Sports Hospital, General Admin. of . Lu has some tips for joggers, and those who are thinking of taking it says people sh ould first evaluate their physical condition, to decide the amount and type of exercise, and jogging in the open air is better running on a treadmill. Conrad Macao will run special programs for the entire month of October this year to support the Hong Kong Cancer Fund39。t conducive to raising a child. She planned to have children once she had achieved career success so she could provide a stable environment for her baby. After 10 years, Xiao felt the time was right, and she tried to conceive for about six months, but was unable to bee pregnant. I conducted prehensive physical checkups. The results suggested that Xiao39。s suggestion that a special day be marked in the year for the global practice of the stressbusting regimen, which is already a multibillion dollar industry in the United States. Modi said in the speech: Yoga is an invaluable gift of India39。s Guangzhou city anized the Chengdu festival. A terrifying wooden bridge in China has just been replaced by a glass one. This, the world’s longest glassbottomed walkway, is located in Shiniuzhai Geopark in Hunan, and spans 300m (984f) and is 180m (590f) above ground. The floor is made of 24 doublelayered glass that is 24mm (), and is reportedly 25 times stronger than regular window glass. The bridge had previously been made of wood, linking the two peaks of Stone Buddha Mountain, but 11 engineers working 12 hours a day converted it to glass. Previously, you were considered brave if you steeled yourself to cross the wooden walkwa
