How To Do Regular Maintenance After Installation Of Rolling Bearing

Rolling Bearing

According to the relevant data, the damage during the installation of rolling bearings accounts for 20% of the bearing damage. How can we reduce the damage during the installation of bearings? The following is a detailed introduction to the specific requirements for the site when installing the bearing. The site must be kept dry and clean to prevent iron filings, sand, dust and moisture from entering the bearing.

The common installation tools of rolling bearings include hammer, copper rod, sleeve, special backing plate, Rolling Bearing screw mosquito fixture, press, etc. the measuring tools include vernier caliper, micrometer, dial indicator, etc., but different tools should be selected according to different bearing models.

After selecting the correct tool, the bearing can be installed. During installation, Rolling Bearing pay attention to whether there are bumps, rust layers, wear debris, sand particles, dust and soil. If any, it will cause installation difficulties. It is necessary to keep the assembly surface of imported bearing and the surface of matched parts clean.

In addition to the cleaning of the assembly surface of rolling bearing and the surface of matched parts, Rolling Bearing pay attention to whether there is corrosion layer on the surface of journal, bearing seat shell hole, shoulder end face, and connecting parts such as bushing, washer, end cover, etc? If any, it can be filed off and polished with fine emery cloth before installation.

How To Do Regular Maintenance After Installation Of Rolling Bearing

1. In terms of bearing speed,

the bearing is determined according to the type, size, Rolling Bearing accuracy, cage type, load, lubrication mode, cooling mode and other factors.

2. For the installation and disassembly of bearings,

they need to be removed and installed frequently in specific applications to ensure that they can be Rolling Bearing inspected and repaired according to their location. Bearings with separate inner and outer rings, such as cylindrical bearings, needle roller bearings and conical bearings, are very suitable for this occasion. With the help of the shaft sleeve, the installation procedure of the taper hole type self-aligning ball bearing and self-aligning roller bearing is also simplified.

3. In some cases,

preloading shall be applied to the rolling bearing to increase the rigidity. This procedure is usually used for the offset of the inner and outer rings of deep groove ball bearing, Rolling Bearing centripetal thrust ball bearing and tapered roller bearing, shaft bending, the change of tolerance of shaft or bearing housing, and matching error will lead to the eccentricity of the inner and outer rings.

In order to prevent excessive eccentric angle,

self-aligning ball bearing, self-aligning roller bearing, or self-aligning bearing seat are better choices. Voice frequency and torque, dynamic bearings are manufactured according to high-precision standards, Rolling Bearing so voice and torque are small. Deep groove ball bearings and cylindrical roller bearings are used for occasions with special requirements for low noise and low torque.

Centripetal thrust ball bearing is a precision part, so it is required to be quite cautious in use, that is, it uses high-performance bearing. If it is not used properly, Rolling Bearing it can not achieve the expected performance effect, and it is easy to damage the bearing. Therefore, pay attention to the following matters when using bearings:

However, under some special operating conditions, the centripetal thrust ball bearing can obtain a longer life than the traditional calculation, especially under light load. Rolling Bearing These special operating conditions are the surface damage that may be caused when the rolling surface (track and rolling parts) is effectively separated and limited by a lubricating oil film. In fact, under ideal conditions, the so-called permanent bearing life is possible.

Grease lubrication includes the sealing method of filling grease in the sealed bearing in advance, and the filling grease supply method of Rolling Bearing filling an appropriate amount of grease in the shell and replenishing or replacing it at regular intervals. In addition, the centralized grease supply mode with pipes connected to each lubrication point is also adopted for the machinery with multiple centripetal thrust ball bearings that need lubrication.

Grease lubrication can be filled with grease for a long time without supplement, and the structure of its sealing device is simple, so it is widely used. Oil lubrication is relatively simple.
