"high-end bearing is dependent on the import, why don't we can't create it?" after investigation of five or six provinces such as dongsan province, zhejiang, shandong, wang dongsheng, the executive deputy director of the shandong technology transformation center of the chinese academy of sciences, found the answer: the biggest problem is in the material "there is no good steel, never make high-end bearings". as a core component of the mechanical equipment, the bearing supports the mechanical rotating body, reducing the friction coefficient, and ensures its rotation accuracy. in his view, regardless of airplane, car, high-speed rail, or high-precision machine tools, instrumentation, "all rotating parts, need bearing".
A few days ago, linxi county mingxin heavy industry machinery co., ltd. successfully developed p2-level screw bearings, product accuracy is 4 times that of japan, the same type of germany; high load capacity angular angular contact ball bearing produced by hebei youtejie bearing co., ltd., the product accuracy reaches p5, and the speed is 2 times the domestic similar products ... and the world's extension, filling a number of white gaps in the linxi bearing industry, also injecting new vitality into the high quality development of the bearing industry.
On may 24-26, 2018, in order to promote the implementation of major shortboard equipment special projects, the ministry of industry and information technology will go to hunan changsha, zhuzhou, xiangtan and other places to conduct field research, understand china's electric, china middle car, china air duty, china wu mine in xiangsui and huayuao, chongde industrial, xiangtan motor and other companies major short board and bearing development, there is a problem, listening to the next policy measures.
It has always been a large gap between prospective technical reserves in prospective technical reserves. however, it is also undeniable that in recent years, there are no shortage of self-contained parts companies in the corresponding technical field, and there are also many companies that are easy to gradually replace import parts. there are also many companies enter the "unknown small paw". "
Northeast network april 23, (liu wei reporter jiang yu) in the spacecraft, there is a part called bearings, "a head" is small, but it is an indispensable role in spacecraft flight. the minimum inner hole diameter is only a few millimeters, only the soybean grain is like, the largest inner hole diameter is only dozens of millimeters, but so delicious but controls the aerospactor activity "posture".
On february 1, 2018, skef participated in a combat counterfeit bearing export action conducted in china, a large number of counterfeit skf brands were all collected in the customs, with more than 2 million yuan. the action is jointly participated by the general administration of customs, and the customs department will issue administrative penalties for the relevant companies. due to the huge amount involved, it is rising to criminal cases, and participating in the fraud will be severely punished by the law. in a seized fake, there is a fake deep groove ball bearing, a tapered roller bearing, a cylindrical roller bearing, and the like. these counterfeit bearings are not allowed to meet the performance requirements of the machine, which is easy to cause large-scale damage to the surrounding machine, causing planned production and financial losses to end users.
On the morning of april 25, with the positive rings, a commodity crime that was charged with the sale of counterfeit registered trademarks was publicly held in the jinniu district tier steel city lamp market. partially invited chengdu, jinniu district two-level people representatives and cppcc members, and the management of the case of the opener of the lamp market. in order to welcome the 4 · 26 world intellectual property day, the rule of law environment for protecting intellectual property rights is created, and the jinkiu district court of chengdu will move this case to the power supply market. before preaching, the golden cow court staff first popularized relevant criminal law knowledge about selling counterfeit registered trademarks. at 10 o'clock in the morning, the trial is long, and the trial is kicked off.
Scrolling bearings are widely used in the basic parts of various types of machinery. the rolling bearings are generally composed of four basic geometric components of the inner ring, outer ring, rolling bodies and holders (commonly known as "four major parts", and most work occasions must have a lubrication. ), the bearing structure bearing structure is usually assembled on the shaft and rotates with the shaft. the outer ring is typically supported in the bearing seat or the mechanical component housing. however, in some applications, there are also outer circles, fixed or inner ring, and the outer ring is rotated; there are more components of components;
