Cross roller bearing is a new type of bearing, which has its special structural characteristics and advantages. Although in foreign countries, both the theoretical research and production technology are quite mature, in China, the research on such bearings is very few. In the design and application of bearings, the bearing capacity and service life of bearings must be considered. In the cross roller bearing, because the cylindrical rollers are vertically arranged on the V-shaped groove rolling surface with a 90 degree shape through spacer blocks, the cross roller bearing can bear radial load, axial load, torque load and other multi-directional loads.

Today's curriculum reform, what kind of classroom does primary school mathematics need? In his lecture, Mr. Zhu Leping used PPT to compare the different design forms and design concepts of new and old textbooks for us, making us clear that the biggest difference between new and old textbooks is that new textbooks are open. It also makes us clear that today's primary school mathematics classroom should attach importance to the application of mathematical thinking methods in combination with the content of textbooks, and let students understand and familiarize themselves with mathematical thinking methods and understand their role in solving practical problems. I have heard experts say what will remain in students' memory after several years? Some knowledge and skills of mathematics are gradually forgotten with the passage of time, but the strategies for solving problems and mathematical thinking methods can be retained and play a strong role in his study, life and work.
