How can I choose the axial clearance of tapered roller bearings? Is there a standard of rolling resistance?
The axial clearance is equal to the radial clearance divided by the tan alpha alpha as the contact angle of the bearing. This is a good formula for the empirical formula, and the radial clearance can be checked according to the bearings
If you are using a single bearing, the bearing is separable, so the axial clearance after the installation of the need to control, limit the axial position can be measured by the dial gauge to measure the shaft (displacement limit position of the push and pull of). Then how to control the axial clearance of much of it, if the general is high accuracy and less heating occasions, you can use the negative clearance measurement, when the push is negative clearance, but that is a slowly varying negative to the process, if you get too tight, may be too tight the axle burned; if your accuracy requirements are not particularly high, I suggest you install when the axial clearance between 100 ~ 300 um. If your shaft is very hot, the clearance needs to be enlarged and burned at the axle shaft. However, if the clearance is too great, the noise will increase and I wonder if you can accept it. This needs your own grasp.
This is not the same as the deep groove ball bearings, so axial clearance and radial clearance have no big relationship, the installation of direct control of axial clearance. First of all, are you using single or paired?.If you are paired, so when you only need to both inner and outer rings of top dead, can, by processing and manufacturing of the channel in the position to control the small clearance, clearance, clearance and clearance of 0 negative 3 cases (mean axial clearance).
