SA-E & SA-ES Rod Ends

SA-E & SA-ES Rod Ends
Rod ends bearings are spherical sliding contact area, large inclination Angle, but also because most joint bearings take special processing methods, such as surface phosphating, galvanized, chrome or external sliding surface lining, gaskets, spraying, etc..Therefore has the big load ability and the anti-impact ability, and has the anti-corrosion, the wear-resisting, from adjusts the center, the lubrication is good or from the lubrication does not have the lubrication dirt pollution the characteristic, even if the installment dislocation can also work normally.Therefore, the joint bearings are widely used in low speed swing motion, tilt motion and rotation motion.Spherical plain bearings and rod end joint bearings have a variety of designs and have different combinations of sliding contact surfaces.Each design and combination has unique properties that make it particularly suitable for certain applications.

SA-E & SA-ES Rod Ends Features

The radial clearance of rod ends bearing must change the relative position relationship of the outer ring, inner ring and rolling body. The intuitive way is to make the outer diameter of the inner ring or the inner diameter of the outer ring change as required.The inner hole of the bearing inner ring is processed into a certain taper, and the corresponding taper is also processed for the shaft neck.After assembly, the position of the inner ring on the shaft is changed by an additional device on the shaft, so that the inner ring is deformed and the outer diameter is changed to adjust the clearance of the bearing.The amount of adjustment is limited, and the gap is too large.The shaft neck needs to be machined to a high precision taper, and additional adjustment device needs to be set, which makes the shaft manufacturing process complex.The inner ring is subjected to great prestress and circumferential tensile stress, which is extremely unfavorable to bearing strength. Sometimes the inner ring will even break during adjustment.Analysis of the bearing structure, the inner ring of this part has been done no way.The outer ring of this part is really simple and simple, with the conventional way of thinking to start, must be another way.After much deliberation and consultation, repeated deliberation, finally enlightened.Changing the radial clearance of the bearing can only be forced from the radial attack, but also from the axial detour.The premise is that we must break through the shackles of the traditional thinking set and the shackles of the habitual forces and dare to innovate.Therefore, the bold idea of bearing the outer ring along the cross - section section.Then, with the help of the interaction between the special surface on the inner ring fairway and the rolling body, the relative axial displacement of the outer ring is converted into the radial displacement of the rolling body, so as to obtain the effect of indirectly changing the radial position among the inner ring, outer ring and rolling body, and achieve the purpose of adjusting the clearance.The outer ring of the bearing is changed from the integral type to the axial split-type combination type, with the double-row rolling body, supplemented by the adjusting gasket group.Rod ends bearing can adjust the radial clearance of the bearing to the required value conveniently by adjusting the thickness of the gasket during assembly. Finally, the jacket is assembled as a whole with threaded connection.When the bearing works for a period of time after wear, also need to reduce the thickness of adjusting the gasket properly, can easily eliminate bad clearance, restore the original accuracy.
