Changes the traditional structure, he has developed a new type of bearing is not all over the world, has won the affirmation

Bearing is a common use of the machine parts, is indispensable in the rotary movement of the mechanical equipment. However, ordinary bearing allows a hovering exercise, but limit the motion of the bearing. The problem about some machinery, especially agricultural products processed machinery, exist a lot of disadvantages. Exciting is that the problem to solve in the northwest agriculture and forestry university of science and technology. Recently, northwest agriculture and forestry university of science and technology, mechanical and electrical college professor kang-quan guo discussion to create 'CURVED TRENCH BALL BEARING' ( A curved groove ball bearing) In the United States, the United States patent no. : US9970484 B2, authorized. This is the northwest agriculture and forestry university of science and technology first, after international PCT way in the United States is empowered to create patents. Biggest changes, curved groove ball bearing is the traditional deep groove ball bearings 'ditch' changed to 'curve channel. Which USES the curve groove groove ball bearing, through the bearing to the existing bearing rotary motion into reciprocating linear motion. Because, today's rotary motion and reciprocating motion transformation mechanism is limited as long as four or five kinds, like crank connecting rod mechanism, slider-crank mechanism, CAM mechanism, swinging ring mechanism, etc. , and curved groove ball bearing can add a kind of new type machine of the rotary motion into reciprocating linear motion mechanism, which is the innovation of the curved groove ball bearing. Curved groove ball bearing's advantage lies in: to apply curved groove ball bearing peeling machine, sheller and other mechanical equipment in the middle, it can complete in the rotation stop oscillating at the same time, while the swing is on shells, peel a rubbing effect, so that they can progress of mechanical efficiency, but also simplifies the structure of the machine more. , a curved groove ball bearing can be applied, both sides will Jane to convert rotary motion into reciprocating linear motion, expand the new methods of mechanical motion transformation, exercises in the textbook for mechanical foundation transformation has added new content, the agricultural products processing machinery, light industry and food processing machinery in universal use. Since this is the northwest agriculture and forestry university of science and technology developed a new kind of structure, and bearing a part widely used all over the world. Apply the patent in China since 2013, 2014 in preference to Chinese nation knowledge property of PCT international application ( Application number: PCT/CN2014/084488) In March 2015, the patent to achieve the world knowledge property rights organization ( 世界知识产权组织| PCT) The international release ( International release number: 2015/035844 send A1) In December 2015, the patent application to enter the United States, released in March 2016 in the United States ( 酒吧。 No：US2016/0123395A1） In August 2016, the patent in China create patent authorized ( The patent number: ZL201310412905. 5) In march, in 2018, the patent authorized to the United States, over five years. It not only represents the northwest agriculture and forestry university of science and technology research and development of patent has achieved international recognition, more represents the northwest agriculture and forestry university of science and technology in the field of patent create international position has improved. Read on: professor kang-quan guo: enjoy special government allowances, won honorary titles such as department of agriculture has outstanding dedication middle-aged and young experts, selected 'country pacesetter project in shaanxi province to the first and second layers and' 35 engineering talents' first level. In terms of scientific research, professor kang-quan guo long engaged in plant material squeeze molding and natural resources research, comprehensive application has run the country natural sciences fund, the ministry of agriculture & # 39948 & # 39 projects, one project, exchanging and shaanxi province kingdom research plan project and so on more than 20 scientific research project. Research papers published more than 70, of which more than 30 papers abroad. Publishing monographs 2, 1 textbooks. 1 create international patents, three kingdom to create patents, 6 items for the new patent.
