A Bearing roller is a type of Bearing. As the journal rotates, it makes circumferential contact with a number of Rollers, which are usually mounted on locating rings. Bearing rollers can be preloaded to achieve good accuracy and rigidity. In addition, the working clearance of the Bearing can be adjusted arbitrarily by the conical inner ring. This solution makes it possible to achieve the requirement of zero play Bearing the rollers of the printing press.
The use of Roller pin Bearing still leaves printer manufacturers fretting about the need for high-precision sheaths and experienced installers to find the right Roller pin set. In order to solve this problem, Bearing manufacturers have developed Bearing roller supports with integrated flanges on the outer ring. In addition, the flange outer ring solves installation and lubrication problems for printer manufacturers. itsBearing rollerSupport solutions have become the mainstream solution for printer roller support.
Bearing rollers can be preloaded to achieve good accuracy and rigidity. In addition, the working clearance of the Bearing can be adjusted arbitrarily by the conical inner ring. This solution completely achieves the requirement of zero play Bearing the rollers of the printing press. Bearing roller clutch is a new type of friction clutch. Compared with the existing overrunning clutch, it has the advantages of high carrying capacity, long life and reliable locking. The dynamic characteristics of the Bearing roller clutch play an important role in its dynamic analysis. The theoretical analysis points out that the torsional stiffness of the clutch is nonlinear, which provides a theoretical basis for the dynamic analysis and structural parameter optimization of the Bearing roller clutch.
WhenBearing rollerWhen the Roller bearing normal load rolls along the raceway, the material under the contact surface will produce elastic deformation. When the contact is removed, most of the elastic deformation is restored. The experiment pointed out that for a given stress value, the deformation generated during loading is always smaller than the deformation during unloading, which causes the pressure in the first half of the contact area to be greater than the pressure in the second half. The contact area is combined with the pressure of the contact area to obtain the resistance torque and the horizontal resistance. This phenomenon, called elastic hysteresis, reflectsBearing rollerThere is a certain amount of energy loss, and its size is related to materials, loads, geometric dimensions, and speeds.
