Cylindrical Roller Bearing The Difference In Structure
Metal solid cage materials used mainly brass, Cylindrical Roller Bearing bronze alloy, there are cast iron and steel, the main structure of the main and two kinds of split, Cylindrical Roller Bearing split the structure of the difference in the most of the way; the overall structure of the difference is reflected in the On the bearing friction, operation and bearing performance improvement.
As the split cage to be integrated after the realization of the function, the main part of the process is easy to consider, and the separation of the connection there are still unreliable problems, therefore, with the progress of technology, Cylindrical Roller Bearing the overall application of the cage will be more and more more.
Split pillar riveting cage from the semi-cage, blankets and rivets, the general use of roller guide. Semi-cage and blanks are generally copper, rivets generally use low-carbon steel. Cylindrical Roller Bearing The structure of the cage roller roller bearings are more commonly used, Cylindrical Roller Bearing with low friction, low temperature rise, low noise, high strength, easy processing, etc., for high-speed and heavy load conditions. The disadvantage is that the presence of rivet holes weakens the strength of the cage and the riveting improperly causes loosening.
The self-riveting cage is composed of semi-cage and stopper. Cylindrical Roller Bearing The half-cage beam ends are riveted, with riveting holes on the flap, Cylindrical Roller Bearing which can be self-riveting without rivets. The structural retainer and the split pillar are riveted Frame structure similar to the technical principle and application characteristics are basically the same, the difference lies in the split cage connection.
Cylindrical roller bearings are supported by pillars through the pillars. Cylindrical Roller Bearing The ends of the struts are threaded, with one end screwed into a retainer ring, Cylindrical Roller Bearing through the hollow roller, and the other end welded to the other retainer On the circle. Sometimes, in heavy duty applications, both ends of the pillar are required to be welded. Cage for the pillar design, Cylindrical Roller Bearing the number of rollers can accommodate more, then higher carrying capacity, generally used for large bearings, such as rolling mill bearings.
Integral Straight Window Holder Structure The cage is generally made of an outer ring guide or an inner ring guide with a straight window with a locking point to lock the roller. Compared with the split cage, the overall cage high strength, work more reliable, but the processing is relatively large, Cylindrical Roller Bearing the window is generally required to use broaching.
Integral arc angle window holder structure, because of its inner surface of the beam for the circular arc, easy to guide and lubrication roller, but increased processing difficulty. This structure can be mainly to avoid the hole between the beam angle and roller interference, Cylindrical Roller Bearing the maximum reduction in the corner of the stress concentration, easy to lubricate.
Double and four-row cylindrical roller bearings are commonly used in the cage is a single claw comb cage and double claw comb cage, double claw comb cage can be loaded into two rows of rollers, two rows of rollers alternately arranged ; Cylindrical Roller Bearing Single claw comb cage to be used in combination of two, the equivalent of a double claw holder radial incision. Cylindrical Roller Bearing Small and medium-sized precision double row cylindrical roller bearings generally use single claw holder; double claw cage is generally used in large bearings.
