Bearing rollerIt is a kind of Bearing. As the important neck rotates, it comes into circumferential contact with a number of Rollers, which are usually mounted on a locating ring.Bearing rollerGood accuracy and rigidity can be achieved by pretensioning. In addition, the tapered inner ring can be used to arbitrarily adjust the working clearance of the Bearing. This scheme can meet the requirement of zero clearance of printing press cylinder Bearing.
Bearing rollerThe use of the pin still worries printer manufacturers, who need high-precision jackets and experienced installers to find the right Roller pin group. To solve this problem, Bearing manufacturers have developed a Bearing Roller bracket with an integral flange on the outer ring. In addition, the flanged outer ring solves installation and lubrication problems for printer manufacturers. Its Bearing roller support solution has become the mainstream solution for printer roller support.
Bearing rollerGood accuracy and rigidity can be achieved by pretensioning. In addition, the tapered inner ring can be used to arbitrarily adjust the working clearance of the Bearing. This solution can fully meet the printing press cylinder Bearing zero clearance requirements. Roller clutch is a new type of friction clutch. Compared with the existing overrunning clutch, it has the advantages of high carrying capacity, long service life and reliable locking. The dynamic characteristics of roller clutch play an important role in its dynamic analysis. The theoretical analysis shows that the torsional stiffness of the clutch is nonlinear, which isBearing rollerThe dynamic analysis and structural parameter optimization of the clutch provide a theoretical basis.
Bearing rollerWhen the Roller under normal load rolls along the raceway, the material under the contact surface will be elastically deformed. After the contact is eliminated, most of the elastic deformation recovers. Experiments show that for a given stress value, the deformation during loading is always smaller than the deformation during unloading, resulting in the pressure in the front half of the contact zone being greater than the pressure in the back half.Bearing rollerofThe contact area is combined with the pressure within the contact area to obtain the moment of resistance and the horizontal resistance. This phenomenon, known as elastic hysteresis, reflectsBearing rollerThere is a certain energy loss, the size of which is related to the material, load, geometry and speed.
