Bearing clearance six big matters

So-called bearing clearance, that is, to show the bearing is not installed on the shaft and bearing box, to fix them one housing, then the party has not been fixed do radial or axial movement of the mobile. According to the moving direction, can be divided into radial clearance and axial clearance. Clearance for the use of the bearing is also very important, so the bearing network told everyone don't blind to this point. Bearing clearance six items: 1, the clearance (in the operation of As the work clearance) About the size of the bearing fatigue life of rolling, temperature, noise, vibration etc. 2, measuring the bearing clearance, to obtain stable measured value, generally impose regulations on bearing load measurement. Therefore, the resulting measured values than real clearance ( As the theory of clearance) Big, that is, to increase the measuring load produced by the elastic deformation. For roller bearing, due to the elastic deformation is small, can be neglected. 3, before installation of bearing internal clearance generally expressed in the theory of clearance. 4, from the theory of clearance minus the bearing installed on the shaft or housing because of the interference fit within the ring of the expansion or contraction after the clearance called 'installation clearance'. Add and subtract in installation clearance for bearing internal clearance after the size change from temperature difference is called 'effective clearance'. 5, bearing installed with mechanical clearance when placed under certain load, the effective clearance and bearing load produced by the elastic deformation of so called 'work clearance'. 6, when the working clearance is slightly negative, the fatigue life of bearing the longest but with the increase of negative clearance with a significant reduction in fatigue life. Therefore, choose the bearing clearance, general work clearance is zero or slightly is advisable. In addition, it is necessary to improve the bearing rigidity or to reduce noise, further negative clearance to work, and when the bearing temperature rise drastically, work clearance should further positively and so on, also must make a concrete analysis according to the conditions of use. 【 Warm prompt. 【 The bearing network] Some information from the Internet, and strive to secure timely, accurate, aims to deliver more information, does not represent our views to its approval or responsibility for their authenticity.
