Installation steps detailed installation steps detailed high temperature bearing shell high temperature and high temperature bearing ring and rolling element bearing shell has high machining accuracy.
In order to guarantee the precision of the high temperature bearing, and the main performance, life must adopt the correct methods and steps, and the use of appropriate tools.
Theoretical proof, high temperature bearing improper installation is often one of the main reasons for high temperature bearing early damage.
According to high temperature and the structure of the bearing type, size and matching performance to determine the high temperature bearing assembly.
Device is commonly used in high temperature bearing pressure method, the temperature difference method and three kinds of hydraulic method.
(
1)
High temperature device bearing cone hole: the cone bearing directly in the high temperature prototype shaft device, pressure can be described using heating methods or means, can use devices to lock nut.
(
2)
Cylindrical hole high temperature affect the bearing device: cylindrical hole of high temperature bearing device, can provide basis for the request, can choose different pressure, temperature and hydraulic method.
So-called high temperature and the clearance of the bearing shell, this means that in the high temperature bearing axis is not attached to the received stated or described in the bearing shell, the shell inside or outside a is fixed, so they are not fixed, either radial or axial movement of the mobile.
Mobile trend, can be divided into radial clearance and axial clearance.
Clearance (in the operation of
As the design task work clearance)
Intrusive for high temperature and the rolling of the bearing of frustrated life, temperature, noise, vibration, and function aspects.
When measuring high temperature bearing clearance, in order to obtain the measured value of the constant, impose rules on high temperature bearing the load measurement.
Therefore, measuring value is greater than the actual gap (
Called the theory of clearance)
, the measurement of load and elastic deformation.
But the roller high temperature bearing, due to the elastic deformation is small, can you can ignore them.
Installation steps detailed high temperature lubricating grease bearing shell ordinary heating temperature does not exceed 80 ℃, smooth, high temperature fuel heating temperature shall not exceed 120 ℃ of the bearing.
Do not allow the high temperature bearing contact at the bottom of the tank, heat set of device also can be applied research induction heating equipment installation will again after high temperature bearing heating mode to make it produce contraction device on the shaft.
High temperature high temperature due to angular contact ball bearings and tapered roller bearing of the radial and axial internal clearance, there is a clear relationship between so you only need to specify a value.
Ordinary is specified by the axial internal clearance.
Then loosen or tighten the nut on the shaft rod or box part of screw shaft hole, high temperature or in IKO bearing ring and stent insertion calibration between gasket or gasket, can range from zero clearance status for the specified value.
Adjust the clearance and the actual methods of measurement setup gap depends on the number of high temperature bearing to be installed.
For example, a method is to use the installed on the wheels of the dial gauge to check the wheel hub design of high temperature bearing axial clearance.
High temperature in the adjustment of tapered roller bearing and the measuring gap, in order to ensure the correctness of ball head and the inner ring rail contact, need a few weeks on axis or high temperature bearing box of different direction of rotation.
If improper contact measurement result is not accurate, and can't count on the purpose of the high temperature bearing adjustment.
