Cone bearing applications, the typical structure is nothing more than the typical structure of the following three:
1. Direct pretightening bearing inner ring
Axial rotation through the nut pressin g the bearing inner ring, to eliminate both inside and outside the ring gap to achieve the purpose of bearing preload.
At present, the commonly used methods for this purpose: First of all, a much larger than the final assembly preload force preload bearing, then the nut returned a 1/4 turn.
This assembly method, the advantages of small investment, the structure is simple, practical, good premise, bearing taper roller quality consistency can be used.angular bearings
The drawback: no quantitative data. Especially: cone roller consistency conditions, we will find: preload bearing preload unstable above, some too large or too small, resulting in unstable assembly quality.
2. Gasket preload
With pad, eliminating the bearing clearance, to achieve the purpose of the axial preload.
Commonly used methods: First, a much larger than the final assembly preload force preload bearings, m easuring the axial size of about minus 0.2mm, get gaskets value. This assembly method, the advantages and disadvantages ibid.
3. Bellows deformation preload
By compression deformation of the bellows to achieve the bearing preload purpose.
At present, the commonly used methods: gas trigger tighten the nut to a value less than the lower limit of the torque through the torque wrench after tightening test rotational torque, then tighten the test repeated alternately, up the two torque are qualified.thin ball bearings
This assembly method, the advantages of small investment, simple structure, bellows and bearing quality consistency under the premise that you can use.
The drawback: no quantitative data. In particular: the bellows and bearing quality consistency conditions, often tighten the force is too large, resulting in waste, resulting in unstable product quality.
