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.
Structure:
This type of bearing is equipped with a round platform roller, the roller by the inner ring of the large rim.
Single row bearings can bear radial load and unidirectional axial load, and double row bearings can bear radial load and bidirectional axial load.Suitable for bearing heavy load and shock load.
According to the different contact Angle (α), it can be divided into three types: small cone Angle, middle cone Angle and large cone Angle. The larger the contact Angle is, the greater the axial load capacity is.
Outer ring and inner assembly (inner ring and roller and cage assembly) can be separated for easy assembly and disassembly.
Characteristics of tapered roller bearings:
1.Suitable for heavy load mechanism, or impact load mechanism;
2.Can bear radial load and axial load at the same time;
3.Tapered stick bearings will have axial force, so they need to be used in pairs;
4.The operation speed is not suitable for high speed;
5.Good lubrication.
