INA thrust tapered roller bearing cage clearance adjustment

Bearing is zoning cage and keep two kinds of structure. One large thrust tapered roller bearing general requirements under high load, often without a cage, but full of rolling element between the inner and outer raceway. While most of the small and medium-sized rolling bearings are with cage. In INA bearings in machining process, the bearing's outer ring, inner ring, rolling body and is how to a cage. Simply put, is to put the bearing inner and outer ring, inner ring pull over, and then put a rolling body ( On one side) , and then adjust the rolling body position, in the end, put the cage. Now everyone knows, in the process of thrust tapered roller bearing is a cage, so bearing cage main exactly is what effect? 1. Adjusting shim method: in the INA bearing cover and bearing seat face between placing a set of soft materials ( Mild steel or elastic paper) Gasket; When adjustment, not first spacer on bearing end cover, a evenly tighten the screw on the bearing end cover, a rotating shaft with the hand, until the rolling element bearing contact with the outer ring and axial internal clearance so far; When measuring thrust tapered roller bearing cover and bearing clearance between end face, plus bearing the axial clearance in normal work need; This is required to fill in spacer thickness, and then fill in the bearing cover and gasket prepared between bearing end face, finally tighten the screws. 2. Adjusting bolt method: press the circle on the INA bearing outer ring, pressurized with adjusting bolts; Before the pressure adjustment, first of all to measure adjustment bolt pitch, then adjust the bolt tightening slowly, until the bearing internal no clearance, and then calculate the adjustment bolt corresponding rotation Angle. For example, pitch to 1. 5 mm, thrust tapered roller bearing clearance required for normal operation, then adjust the bolt required rotation Angle of 3600 * 0. 15／l. 5 = 360; Then turn the adjusting bolt against 360, miniature bearing was 0. 5 mm axial clearance, and then use gaskets to be fixed can stop. INA bearing called window, used to isolate and guide roller, the cage pocket hole clearance in radial and axial activity to a certain extent, the radial clearance of total activity called cage. In roller cage has a variety of structural types, complicated shape. Keep on many equidistance hole, hole shape is spherical, tooth type, such as round, oval, rectangular, and its size is greater than the rolling body size, the difference between the two for the pocket hole clearance, sometimes to keep rolling connection part between window called the lintel, it ACTS as connection and increase strength of cage.
