The two sides of the performance of needle roller bearings crack

Needle roller bearings crack source performance of two aspects: the site author: the administrator to release time: 2017 - 12 - 14 16:59:09 views: 0 needle roller bearings crack performance when it comes to bearing this kind of parts, both as an important part of industrial equipment, in use process, if for bearing its own problems, cause the damage of equipment and fault is a pyrrhic victory. This requests us in peacetime to needle roller bearing maintenance and troubleshooting work, first of all, we need to understand the cause of the cracks in needle bearing of two aspects. Only by understanding the needle roller bearings and the possibility of cracks to get our bearings in the industrial production and processing activities play a good role. Cracks in two aspects: first, on the surface, the spherical roller bearing in the process of rolling contact, because of the work in the plastic deformation and strain hardening on the surface of the contact stress on the surface of the cyclical changes caused by the effect of external load, and finally on the inner surface of the small crack from the development, the formation of surface crack between the two, because Xie into the lubricant on the surface of the work, the power of the open, crack down on the wall, crack force to move forward. Second, from the surface, again and again under the pressure of the surface contact, the early crack depth specified in the exposed surface of cracks, and along the surface direction Angle, to the specified depth, since on the surface of contact area, and more than the surface, and finally formed the corrosion, leaving a hole. From the bearing surface, or from the surface of the crack, if parts surface quality is poor, there is a defect ( Oxidation and decarburization) Poor lubrication, friction or from the surface crack. Don't ignore the needle roller bearing cracks, slowly accumulation will lead to the use effect of the bearing. Through the description of the above, we recognize the cracks shown in two aspects of needle roller bearings, surface and the inside will be lead to crack of the bearings. Professional needle roller bearings factory, choose jiaxing needle bearing, bearing in our company product type many, the price is very affordable.
