If this kind of bearing is used improperly, are there any precautions?
(1) Keep tapered roller bearings and their surroundings clean.
Even small dust that can't be seen by the eye will bring bad effects to the bearing. Therefore, keep the surrounding clean, so that the dust will not invade the bearing.
(2) Use with care and caution.
Strong impact on tapered roller bearings in use will produce scars and indentations, which will become the cause of accidents. In serious cases, there will be cracks, fracture, so must pay attention to.
(3) Use the appropriate operating tools.
Avoid replacing existing tools with the right ones.
(4) Pay attention to the corrosion of tapered roller bearings.
When operating bearings, sweat on the hands will become the cause of rust. Be careful to use clean hands, preferably wear gloves as much as possible.
How to install tapered roller bearings?
Adjusting axial clearance For the installation of tapered roller bearing axial clearance can be adjusted by adjusting nuts on the journal, adjusting gaskets and threads in the bearing seat hole, or by pre-tightening springs and other methods. The size of axial clearance is related to the arrangement of bearing installation, the distance between bearings, the material of shaft and bearing seat, and can be determined according to working conditions.
For tapered roller bearings with high load and high speed, the influence of temperature rise on axial clearance must be considered when adjusting clearance, and the reduction of clearance caused by temperature rise must be estimated. That is to say, the axial clearance should be properly adjusted to a larger extent.
For bearings with low speed and bearing vibration, no-clearance installation should be adopted, or pre-load installation should be applied. The purpose is to make the tapered roller bearing roller and raceway have good contact, uniform load distribution, prevent the roller and raceway from vibration impact damage. After adjustment, the size of axial clearance is tested with a micrometer.
Single-row tapered roller bearing
A single-row tapered bearing is usually adequate for the most straightforward applications (e.g., angular forces on a fixed point and with only mild fluctuation). To find the right one, you'll need to determine whether the end-use of the tapered bearing will have more radial or axial loads. There are axial-only tapered roller bearings called thrust tapered bearings that resemble flat rings or disks where the rollers are perpendicular to the bearing bore axis. When multiple bearings are required, it could be advantageous to use two- or more single-row tapered bearings rather than multi-row bearings within a single housing. One such example is if one bearing will need to be maintained, adjusted, or replaced separately from the other. Another is when there is a need to allow for flexibility in design and add or subtract individual single-row tapered bearings, which is impossible with a multi-row tapered bearing.
