How To Install The Thrust Bearing In The Imported Bearing

Imported Bearing

Installation method of thrust bearing in imported bearing. The fit between thrust bearing and shaft is generally transition fit, and the fit between seat ring and bearing seat hole is generally clearance fit. The middle shaft ring of bidirectional thrust bearing shall be fixed on the shaft to prevent rotation relative to the shaft.

Generally, the installation method of thrust bearing is mostly shaft rotation, so the fit between inner ring Imported Bearing and shaft is win-win fit, and the fit between bearing outer ring and bearing chamber is clearance fit.

How To Install The Thrust Bearing In The Imported Bearing

When installing the thrust bearing, check the verticality of the shaft ring and the shaft centerline.

The method is to fix the dial indicator on the end face of the box shell, make the contact of the dial indicator push on the raceway of the bearing Imported Bearing shaft ring, rotate the bearing and observe the pointer of the dial indicator. If the pointer swings, it indicates that the shaft ring is not perpendicular to the shaft centerline. When the shell hole is deep, it can also be inspected with an extended dial indicator.

When the thrust bearing is installed correctly, its seat ring can automatically adapt to the rolling of the rolling element to ensure that the rolling element is located in the raceway of the upper and lower rings. If it is installed reversely, not only the bearing does not work normally, but also the mating surfaces will be seriously worn. Since the difference between the shaft ring and the seat ring is not obvious, extra care should be taken during assembly.

In addition, a clearance of 0.2-0.5mm shall be reserved between the thrust bearing race and the bearing seat hole to compensate for the error caused by inaccurate processing and installation of parts. When the center of the Imported Bearing bearing ring is offset during operation, this clearance can ensure its automatic adjustment, avoid contact friction and make it run normally. Otherwise, the bearing will be severely damaged.

The above two methods can significantly simplify the installation process.

The oil filling equipment required to operate the hydraulic nut and use the oil filling method is supplied. For details of these products, see the relevant section in the online catalog “maintenance and lubrication Imported Bearing products”. When the hydraulic nut is used to install the bearing, it must be positioned on the threaded part of the journal or the thread of the sleeve,

so that the annular piston is close to the inner ring of the bearing, the nut on the shaft or the retaining ring installed at the shaft end. Press the oil pressure into the hydraulic nut Imported Bearing through Imported Bearing the oil pump to move the piston axially with the force required for accurate installation. Use the hydraulic nut to install the spherical roller bearing onto the

Using the oil injection method, the oil is injected between Timken bearing and journal under high pressure to form an oil film. This oil film separates the mating surfaces and significantly reduces the friction between the mating surfaces. This method is generally used when installing the bearing directly on the conical journal, but it is also used to install the bearing on the set sleeve and push sleeve specially prepared for the oil injection method.

The oil pump or oiler generates the necessary pressure to inject oil between the mating surfaces through the groove and oil distribution channel on the shaft or sleeve. When designing the bearing layout, the necessary grooves and channels on the shaft must be considered. The spherical roller bearing is installed on the withdrawal sleeve with oil groove. The withdrawal sleeve is pressed into the bearing hole by injecting oil into the mating surface and tightening the screws in turn.
